Can Obstructive sleep apnea cause cognitive decline?

Can Obstructive sleep apnea cause cognitive decline?

Comments 0 Comment

According to a study, people who have obstructive sleep apnea may experience cognitive decline.

The study is distinctive because all of its subjects were in good health and were free of the comorbid conditions that are frequently cited as the processes behind the association between sleep apnea and cognition.

According to the study, males as young as middle age can experience cognitive decline brought on by obstructive sleep apnea.

When a person has obstructive sleep apnea (OSA), their airway occasionally becomes obstructed for at least 10 seconds while they are asleep. It has been hypothesised that the cardiovascular or metabolic comorbidities that cause these breathing disruptions are the cause of the eventual decline in cognitive function.

According to a recent research of individuals without these comorbidities, sleep apnea itself can cause cognitive deterioration as early as age 40.

Men from a distinctive group took part in the study. People with systemic hypertension, hyperlipidemia, diabetes, cardiovascular disease, and other metabolic illnesses are more likely to be diagnosed with OSA.

This study is the first to examine the cognitive impact of OSA in otherwise healthy and non-obese persons because none of the study participants had any such comorbidities.

In their otherwise healthy subjects, the researchers discovered that OSA was associated with worsened executive function, visuospatial memory, vigilance (sustained attention), psychomotor function, and impulsive control.

Obstructive sleep apnea

According to a recent examination of data from 16 countries, 425 million adult men and women between the ages of 30 and 69 have moderate-to-severe OSA, and 936 million have mild-to-severe OSA. One estimate places the number of Americans with the illness at 25 million.

Sleep apnea might be one of two forms. The brain is unable to regularly signal the breathing muscles in people with less common central sleep apnea. OSA is more prevalent.

The dilator muscles that normally maintain the soft palate at the back of the throat open during breathing malfunction in people with obstructive sleep apnea or enable the tongue to impede the airway. Respiration is halted until the affected individual gasps or snorts to reopen the airway and restore breathing, which frequently happens before they completely awaken.

The link between obstructive sleep apnea and cognitive decline

According to the study’s findings, males who had severe obstructive sleep apnea had deficiencies in:

  • Vigilance
  • executive ability
  • Visual recognition memory in the short term
  • esteem on a social and emotional level

These issues were present in the males with mild obstructive sleep apnea as well, though not to the same extent as the individuals with severe versions of the illness. In reality, they hardly ever outperformed the control group in a meaningful way.

Even though the majority of men with sleep apnea had medical comorbidities, the study’s participants had none, including cardiovascular disease, diabetes, chronic inflammation, or depression. The authors pointed out that earlier studies blamed concomitant illnesses rather than sleep apnea for cognitive deficiencies.

Ivana Rosenzweig, MD, Ph.D., FRCPsych, a sleep specialist and consultant neuropsychiatrist, and the study’s lead author, said in an email to Healthline that “in our small proof-of-concept cross-sectional study, we demonstrated cognitive deficits in male patients with obstructive sleep apnea, even without any comorbidities.” This is extremely relevant because the current prevailing theory holds that cognitive deficiencies in this age range may be caused by comorbidities connected to obstructive sleep apnea.“

Rosenzweig stated, “Our research demonstrates that sleep apnea is sufficient to initiate cognitive alterations. Since the majority of these patients were (otherwise) healthy males with this condition, the vast majority of them were consciously ignorant that they already had cognitive abnormalities detected by the extremely sensitive testing battery.

The following are some potential causes of the cognitive issues, according to the researchers:

  • sporadic low oxygen
  • high blood carbon dioxide levels
  • changes in the brain’s blood flow
  • fragmented sleep
  • Neuroinflammation

They stated that sleep apnea is a disorder that could be harmful.

Sleep apnea and dementia

The chance of developing dementia, including Alzheimer’s disease, may be considerably raised by sleep apnea. An assessment of research from 2022 found that it does not appear to raise the likelihood of acquiring vascular dementia.

Unfortunately, dementia can also cause sleep disruptions, according to Merrill. “Sleep disturbances increase dementia risk,” she said. As a result, your memory may eventually deteriorate to the point of dementia, which will make it harder for you to sleep. In this way, disturbed sleep can contribute to a downward spiral, making it even more crucial to recognize and address sleep problems during early and midlife adult development. Dementia affects sleep in several different ways, Merrill continued. “Dementia is a neurodegenerative illness, which means that brain cells begin to malfunction and die as time passes.

The brain’s sleep centres begin to malfunction when a person loses brain cells, making it harder for us to communicate with our bodies to stay asleep. Sleep is frequently broken up or even inverted, keeping patients awake all night before they fall asleep for the most of the day.

Merrill stated, “Ideally, sleep will be optimised years before the potential onset of dementia.” “With better sleep, we may be able to postpone the age at which dementia first manifests itself. To increase a person’s healthy life span as much as feasible, sleep quality should be improved.

The CDC recommends that those aged 61 to 64 receive seven to nine hours of sleep per night, while those aged 65 and over should aim for seven to eight hours.

Causes of OSA and cognitive damage

“Craniofacial and physiological particularities can be a risk factor for OSA — having a short chin, large tonsils, a large tongue, etc.,” said neuroscientist Dr. Nadia Gosselin from the University of Montreal in Canada, who was not involved in the study.

According to her, “these peculiarities increase a person’s risk of upper-airway obstruction during sleep.”

Although it is unclear how OSA causes cognitive loss, several of its fundamental characteristics, such as sleep disruption, intermittent hypoxemia, neuroinflammation, and oxidative stress, may be to blame.

According to Dr. Gosselin, OSA stops sleep from playing its part in memory consolidation, brain plasticity, and the elimination of cerebral metabolic waste by continuously fragmenting sleep.

She stated that systemic inflammation and blood-brain barrier disruption resulting in neuronal death are two more potential causes.

According to one study, the hippocampus and the entorhinal cortex, two areas of the brain that degrade quickly in Alzheimer’s disease, have higher levels of oxidative stress and inflammation.

How to treat sleep apnea

The good news is that OSA can frequently be treated by making small lifestyle adjustments, such eating better, working out more, and decreasing weight, she continued.

Through a range of therapy techniques, doctors can also assist patients in controlling OSA.

The CPAP machine, which uses continuous positive airway pressure to keep the airway open while you sleep, is the OSA technology that is used the most frequently. People with central sleep apnea may also be given medication, CPAP machines, or other breathing aids.

Other OSA therapies include oral mandibular advancement devices or dental appliances that prevent the tongue from obstructing the throat. Additionally, there are neurostimulation implants for OSA, and surgery can occasionally be beneficial.

Melatonin and reduction in risk of youth Self harm.

Melatonin and reduction in risk of youth Self harm.

Comments 0 Comment

Researchers examined how melatonin consumption affected children’s and teenagers’ self-harm. They discovered that melatonin consumption reduced self-harm in children and adolescents. Particularly in adolescent girls who were depressed and anxious.

These findings and the potential advantages of melatonin for mental health and wellbeing require further research to be confirmed. Young people frequently experience sleep difficulties including insomnia, particularly those who have psychiatric issues.

Some estimates place the number of young people who self-harm at roughly 17%. There aren’t many treatments for the disease among young people that have empirical backing right now.

According to a recent meta-analysis, addressing the root reasons of self-harm may lower its prevalence. Hence, some have proposed that correcting sleep issues may lower the frequency of self-harm.

Melatonin is the most frequently prescribed medication in Sweden for treating sleep disorders in kids and teenagers. A hormone that occurs naturally, melatonin supports a healthy sleep-wake cycle as well as other biological functions.

Treatment options for the habit might be improved by learning more about how melatonin influences self-harm in children and teenagers. Recently, researchers looked at the risk of self-harm and unintentional injuries in young people with and without psychiatric problems before and after melatonin administration.

They discovered that taking melatonin was associated with lower rates of self-harm, particularly among adolescent girls who were depressed and anxious. Journal of Child Psychology and Psychiatry published the paper.

Why Do Young People Self Harm?

There are several reasons why kids and teenagers self-harm. A traumatic event, like abuse, or a mental illness, like anxiety or depression, are frequently to blame.

Youth who self-harm may also be unable to articulate their emotions or feel like they have no control over their lives. Self-harm is not a healthy behaviour and should be seen as a cry for help rather than a coping mechanism for uncomfortable emotions.

It’s possible that kids and teenagers have trouble expressing their emotions. You can encourage kids to start talking about what’s going on in their lives by paying attention to what they are saying and doing.

Decreased risk of self-harm with melatonin

For the study, the researchers analyzed public healthcare data from 25,575 youths in Sweden who began melatonin treatment between ages 6 and 18.

The children and adolescents were followed for a year prior to melatonin prescription and a year following. They began treatment at an average of age 13 years old, and most commonly initiated treatment in November. Treatment lasted for an average of 6.4 months.

The researchers found that 87.2% of melatonin users received at least one psychiatric diagnosis by age 18. Over 50% received an ADHD diagnosis. Self-harm was around five times more common in girls than boys.

In the end, the researchers found that melatonin use decreased the risk of self-harm by 42% and poisoning risk by 41%. Effects were especially prevalent among girls and adolescents with depression and or anxiety.

They noted, however, that melatonin use did not decrease rates of bodily injuries, falls, or transport accident rates.

Limitations

Even though he was not engaged in the study, Dr. Lokesh Shahani, an associate professor of psychiatry at UTHealth Houston’s McGovern Medical School, commented:

“Some cases were overlooked since the study employed a national registration to obtain patient diagnosis, prescription, and death records. Moreover, no research was done in this city on the impact of various sleep aids on suicidal behaviour.

As several of the study participants also took antidepressants, Dr. McGrath continued, it’s probable that their use had an impact on the study’s findings.

Dr. Johnson-Arbor cautioned that the findings might not be applicable to other nations. Where melatonin is sold as a dietary supplement rather than a prescription, is less strictly regulated. This may be tainted with other drugs.

How melatonin may help mental health?

Dr. Kelly Johnson-Arbor, a medical toxicologist, co-medical director, and interim executive director of the National Capital Poison Center who was not involved in the study, responded to a question on how melatonin can decrease self-harm in young people by saying:

Melatonin, a hormone naturally produced by the brain, aids in controlling circadian rhythm and sleep-wake cycles. Young persons with psychiatric disorders frequently experience sleep disruptions, and childhood emotional and behavioural problems have also been linked to sleep issues.

It’s feasible that changes in sleep quality will lead to gains in emotional stability and behavioural control given that sleep issues can affect mood and conduct, said Kelly Johnson-Arbor, M.D.

Because of this, she explained, the authors of the study “sought to explore if management of the sleep cycle, through the use of melatonin, might potentially help avoid self-harm, body injuries, and falls in young individuals between the age of 6 and 18 years old.”

Melatonin during puberty

Depending on the animal species, melatonin administration was found to either hasten or postpone the onset of puberty in animal studies. Gonadotropin-releasing hormone, which controls puberty in humans, is produced by the brain. It may be altered by melatonin treatment, according to Dr. Johnston-Arbor.

“The development of female reproductive organs may be affected by melatonin as well. Yet, numerous human trials including kids who received melatonin for extended periods of time did not reveal any negative impacts on puberty, she continued.

Dr. Michael J. McGrath, a board-certified psychiatrist and medical director of The Ohana Luxury Alcohol Rehab who was also not engaged in the study, responded when asked the same question by saying:

Melatonin should be used with caution in prepubescent children because there is conflicting information and no conclusive evidence linking it to changes in the timing of puberty.

Melatonin dosage recommendations are still unclear.

The results “suggest that children with sleep disorders may experience additional benefits, other than sleep control, after the use of melatonin,” Dr. Johnson-Arbor stated in response to a question regarding the study’s implications.

“More studies are needed to confirm the appropriate amount and duration of usage of melatonin needed to achieve the effects discovered in this analysis,” she said. “This study’s results may not generalise to other populations, and these findings warrant further exploration.”

Insufficient sleep tied to increased risk of stroke.

Insufficient sleep tied to increased risk of stroke.

Peripheral artery disease (PAD), which affects more than 200 million people worldwide and results in blocked arteries in the legs and raises the risk of stroke and heart attack, is a condition that causes blocked arteries, and new research published in the European Heart Journal has shown a strong correlation between sleep habits and the development of PAD.

Researchers discovered that compared to people who sleep 7 to 8 hours each night, those who sleep less than 5 hours have a 74% increased risk of developing PAD. The study stresses the need of getting enough sleep for preserving vascular health and delaying the onset of PAD.

A recent study that was just published in the European Heart Journal found a strong connection between getting too little sleep and an elevated risk of peripheral artery disease (PAD).

In comparison to people who follow a healthy sleep schedule of 7 to 8 hours per night, the research showed that people who sleep fewer than 5 hours each night have a 74% higher risk of developing PAD.

Both excessive daytime naps and insufficient sleep at night have previously been associated with an increased risk of coronary artery disease, which, like PAD, is brought on by blocked arteries. With the goal of filling in the knowledge gap about how sleep habits affect PAD and how they affect it the other way around, this study sought to provide insightful information.

Using genetic data to study PAD risk

Almost 650,000 people participated in the survey, which was conducted in two phases. The first thing the researchers did was look at how napping during the day and how much sleep an individual gets at night correlated with their chance of developing PAD.

They next performed a Mendelian randomization analysis utilising genetic data to see whether these relationships were indeed responsible for the elevated risk of PAD.

Mendelian randomization is a research technique that examines whether there is a cause-and-effect link between specific factors and a specific outcome using genetic data. In layman’s terms, it is comparable to a natural experiment that makes use of the randomness with which our genes are passed along.

Stronger evidence for probable causal ties is produced by this strategy, which assists researchers in distinguishing between real cause-and-effect correlations and merely associational relationships.

The possibility of reverse causality is one of the drawbacks of observational research, making it difficult to determine whether sleep habits caused PAD or if having PAD affected them when a link between them and the condition is found.

Mendelian randomization is a trustworthy method for determining causality, increasing the confidence in the results.

Link between short sleep duration and PAD

Sleeping less than 5 hours each night compared to sleeping 7 to 8 hours significantly quadrupled the risk of PAD in observational research involving 53,416 adults. This result was confirmed by other analyses involving 156,582 and 452,028 individuals.

In the causative investigations, not only was short sleep associated with an increased risk of PAD, but PAD was also associated with an increased risk of short sleep.

These findings imply that insufficient nighttime sleep increases the risk of PAD development and that PAD itself increases the risk of insufficient nighttime sleep.

An observational study of 53,416 adults indicated that sleeping for more than eight hours per night was linked to a 24% higher risk of PAD than sleeping for seven to eight hours.

Analyses in two larger groups of 156,582 and 452,028 people provided support for this observation. However, no cause-and-effect relationship was observed between extended sleep and PAD.

Similar results were reported for daytime napping, when nappers had a 32% higher risk of PAD than non-nappers, although no causative links were found.

“This is a well-put-together study that better examines the link of sleep length with PAD,” said Dr. Rigved Tadwalkar, a board-certified cardiologist at Pacific Heart Institute in Santa Monica, California, who was not involved in the study.

According to Dr. Tadwalkar, “The study is of high value because earlier studies addressing this link have been limited because of less reliable study design and lower statistical power.”

Study implications

Dr. Tadwalkar told that the American Heart Association released a document titled “Life’s Essential” last year, adding that the consequences for patients and the general public are enormous.

It aims to enhance public health by offering recommendations for lifestyle modifications that can lower the risk of cardiovascular disease. The paper is an update of “Life’s Easy.” The most recent update includes an eighth element that emphasises sleep length.

According to other studies, “Life’s Essential 8” makes it clear that getting between 7-9 hours of sleep each night is ideal from a cardiovascular standpoint.

What do the experts think?

In order for people to improve their health results, Dr. Tadwalkar also emphasised the need for “increased understanding of the importance of high-quality sleep for individuals.”

This study “adds to the growing body of data demonstrating strong and consistent links between sleep quality and risk of developing cardiovascular disease,” according to Dr. Devin W. Kehl, a cardiologist at Providence Saint John’s Health Center in Santa Monica, California who was not involved in the current study.

The majority of people are aware of how crucial it is to maintain a balanced diet and engage in regular exercise to reduce one’s chance of developing heart disease. Now, with studies like these and others, it is becoming more and more obvious that we also need to think of sufficient sleep duration and sleep quality in the same category as an important lifestyle habit, according to Dr. Devin Kehl.

Although not engaged in the study, board-certified physician Dr. Collin Johnston stated: “In my years of practising medicine, I have always believed that the western medical model must strive and focus more on the prevention of disease rather than merely the treatment of sickness.”

Dr. Johnston continued, “Unfortunately, during my medical school and residency training, a relatively small portion of time was spent learning the importance of basic health principles such as well-balanced nutrition, regular and frequent physical activity, and the integral role that quality “sleep hygiene” practises can play in helping prevent the onset of chronic health conditions.

Sleep and Heart Health During Pregnancy

The heart is put under greater stress during pregnancy, and some women experience cardiovascular issues at this time. For instance, high blood pressure can develop or get worse during pregnancy, which could have negative effects on both the mother and the unborn child.

Several pregnant women struggle with insomnia, sleep apnea, and other sleep disorders, and research has linked these concerns to an increased risk of cardiovascular diseases both during and after pregnancy. With the aim of lowering hypertension and other cardiovascular problems, ongoing research investigations are attempting to determine how to make pregnancy sleep better.

Important ways to consider to avoid afternoon slumps.

Important ways to consider to avoid afternoon slumps.

Comments 0 Comment

The majority of us have experienced highly productive mornings where we finished assignments. Also, worked to clear our inboxes and resisted the impulse to tweet at our coworkers. As 2:00 rolls around, you might as well close the blinds, put on your jammies, and go to bed.

Whenever the afternoon comes around, it’s quite normal to feel extremely exhausted. The noon slump can be caused by circadian rhythms, which have an impact on your sleep patterns.

You may wish to take an afternoon nap because your “sleep signals” actually peak at night and in the afternoon (at around 2 p.m.).

Your energy may also be impacted by other elements, such as what you eat, and how well you’re hydrated. Also, how much time do you spend staring at a screen.

Consider it time to relax on your office chair. Here are some strategies for combating weariness as soon as it manifests.

What is the Afternoon Slump?

As your energy levels drop in the late afternoon, it’s known as the afternoon slump. You may find it difficult to focus at work, lose interest in working exercise, and feel overall lethargic. Also, slow, and unable to think of anything other than snatching up another cup of coffee or fitting in a quick sleep.

Not simply in the mid-afternoon slump do you feel exhausted. Your morals and self-control are compromised, as well as your ability to drive safely.

What Causes the Afternoon Slump?

Contrary to popular perception, a big lunch is not what causes the afternoon slump (but it can be exacerbated by one). Your circadian cycle is to blame.

The internal biological clock in your body is called the circadian rhythm. This clock regulates things like your sleep-wake cycle when your body generates specific hormones. Also, when your body temperature changes on an approximately 24-hour cycle.

Your daily timing can vary, but your generally steady flow of energy takes the form of:

  • You experience grogginess or sleep inertia when you awaken.
  • You experience your initial energy surge in the morning.
  • You have an afternoon blah.
  • In the late afternoon or early evening, you experience a second-wind energy surge.
  • Your activity level decreases till sleep

So, the majority of the time, your body’s biological makeup is to blame for your energy slump in the afternoon. There might, however, be more factors at work.

You might experience afternoon fatigue more than usual if:

  • You haven’t had enough rest.
  • Your circadian cycle is out of whack.
  • You suffer from a sleeping issue such as sleep apnea.
  • You have a medical issue like ADHD that makes it difficult for you to sleep and stay awake.

How to Beat the Afternoon Slump?

Lower Your Sleep Debt

The amount of sleep you owe your body in total is called your sleep debt. It is compared to your sleep demand, which is the amount of sleep per night that is controlled by your genes.

According to one study, the recommended amount of sleep per night is 8 hours 40 minutes, plus or minus 10 minutes. Although 13.5% of people may require 9 hours or more.

To find out your exact number, turn to the RISE app. Your exact amount of sleep is determined by RISE using historical phone use data and proprietary sleep science-based models. The amount of sleep debt you are carrying can then be calculated by the app. To feel and perform at your best, we measure this over the previous 14 nights and advise that you keep it under five hours.

Even while you can always have a fall in energy in the afternoon, you’ll notice it more after a sleepless night or when your sleep debt is high. Reduce your sleep debt to lessen how tired you feel overall and in the afternoon slump.

Sync Up with Your Circadian Rhythm

Your circadian rhythm is what makes you feel so weary in the afternoons, but if you’re not synchronizing your lifestyle with it, you may feel even less energised at this time and throughout the rest of the day. Circadian rhythm may be out of whack if:

  • You work the night shift.
  • You’re living contrary to your chronotype. For example, if you force yourself to get up early while being a night owl. Here, we discuss how to maximize the potential of your chronotype.
  • When your physiological clock and social clock don’t sync. This can happen due to an erratic sleep routine, you get social jet lag. For instance, 87% of us, on average, go to bed two hours later on the weekends than we do during the week.

Schedule Your Day

You can lessen how severely the afternoon slump affects you each day by reducing your sleep debt and synchronizing with your circadian clock. The energy slump is still a normal aspect of your biology, therefore you’ll probably always experience it to some degree.

Working with the slump rather than against it will help you if you can’t overcome it. Employ rise to determine when your daily afternoon slump will occur, and then plan your day accordingly.

For instance, if at all possible, plan simpler work for your afternoon slump, such as administrative duties, emails, and catch-up meetings with low stakes. Reserve laborious chores, like writing, programming, or making presentations, for when your energy is at its highest.

Take a Break

Sometimes, during your afternoon energy slump, you can’t even do simple administrative activities. It’s better to take a break at this point and take a step back.

Take a stroll, finish some pointless housework, or engage in a soothing hobby like reading or listening to music. After you feel more energised and capable of being productive, return to work.

Use your weekend afternoon slump for some peace and quiet. Read a book, watch TV, or snooze with the kids (more on the power of naps below).

According to research, judges tend to make less favourable decisions on cases as the day goes on, but taking a break allows them to refocus. It is preferable to take brief but frequent breaks throughout the day, and to avoid waiting until the end of your schedule. Even taking pauses has been found to keep you focused on your objectives.

Work on a Task

Although if it doesn’t seem like it while you’re exhausted, the afternoon slump may be the ideal time to concentrate on a project that calls for insight, creativity, and problem-solving abilities.

According to research, you might be more adept at these tasks when your circadian cycle is not at its best. Hence, even though the afternoon is typically best suited for simple chores, try working on a challenging job on your to-do list during your afternoon slump to see if your brain can come up with new answers then.

Go to sleep

If you’re sleep deprived, taking a nap will help you reduce your sleep debt and increase your vitality. Even if you’ve been getting enough sleep lately, a midday nap can still assist to increase your energy, mood, and performance.

The best time to take a nap is also during your afternoon slump because sleeping now shouldn’t make it more difficult to fall asleep later.

It has been demonstrated that taking a 10-minute sleep in the afternoon increases vigour, vitality, and cognitive performance. Some of these advantages remain for more than 2.5 hours, so you should be able to finish the rest of the workday.

Get Some Exercise

The last thing on your mind in the afternoon when you’re feeling drowsy is exercising. Nonetheless, exercising might aid in removing exhaustion so that you can return to work feeling rejuvenated.

Even while you might not be setting any personal records at the gym, if you want to save your energy peaks for work and family time, your afternoon energy slump may be the perfect time to work out.

Also, a 2020 study indicated that exercising between 3 and 6 p.m. had greater metabolic benefits than exercising between 8 and 10 a.m. for people who were either at risk for or had been diagnosed with type 2 diabetes.

Drink Caffeine in the Morning but avoid in afternoon

The seductive call of a cup of coffee might be difficult to resist when the afternoon slump sets in. Yet, caffeine can stay in your system for up to 12 hours, so an innocent cup of coffee at 3 p.m. might keep you up at night. Your sleep debt will increase as a result, which will worsen your afternoon slump the following day.

Yet there’s another way that coffee can help you get through the mid-afternoon lull.

The half-life of caffeine is between three and seven hours. Thus, it takes three to seven hours for the quantity of caffeine in your system to decrease by half, and another three to seven hours for it to decrease by half once again, and so on.

Socialize with Friends or Colleagues 

Your energy can increase by socialising. Hence, if you’re experiencing a mid-afternoon energy slump, stop by a colleague’s desk for some energising small talk (if they’re also experiencing a dip in energy) or work on a project together. During this time, you can also take a break and talk to a friend or family member.

As you interact with others, dopamine and oxytocin are released, which improves your mood, lowers your cortisol levels, and lessens stress.

Need one more justification to invest in relationships? Your sleep may improve, giving you more energy throughout the day and throughout the afternoon slump.

Need one more justification to invest in relationships? It might help you get better sleep, which will give you more energy throughout the day, including during the afternoon slump.

Eat a Healthy Lunch 

We know we mentioned your lunch isn’t the cause of the afternoon slump, but if you eat the wrong items, it can make matters worse. Your afternoon energy slump may be considerably worse than usual if you eat a meal high in carbohydrates or sugary snacks.

According to research, a big lunch results in higher drowsiness and subpar performance on simulated driving exams. Make a point of choosing lunches that are high in vegetables, whole grains, complex carbohydrates, and healthy fats.

Go for things like bananas, chickpeas, kimchi, and tempeh. A 2022 study revealed that a diet strong in prebiotic and fermented foods reduced felt stress and increased subjective sleep quality.

Can Insomnia Increases the Risk of Heart Attack?

Can Insomnia Increases the Risk of Heart Attack?

Not only is getting enough sleep crucial for your energy levels, but also for the health of your heart. Discover the link between heart health and sleep.

Sleep is not an indulgence. It is essential for health. Your body can mend itself while you sleep. Also, getting adequate restful sleep enables you to go about your day properly.

Sleep gives the body the chance to recover and replenish, and it is crucial for almost every element of physical health. Insufficient or interrupted sleep can increase the risk of cardiovascular conditions such heart disease, heart attacks, diabetes, and stroke. It can also affect blood pressure and increase the likelihood of heart attacks.

As a result, getting enough sleep can contribute to living a heart-healthy lifestyle. Also, for those with heart issues and may help prevent harm to the cardiovascular system in healthy individuals.

How much sleep do I need?

Adults typically require at least 7 hours of sleep per night. 1 The majority of American adults—more than 1 in 3—state that they don’t receive the necessary amount of sleep. 2 While this could be alright for a day or two, chronic sleep deprivation can cause serious health issues and exacerbate some already existing conditions.

Health conditions linked to lack of sleep

People who sleep for fewer than 7 hours a night are more likely to report having health issues, such as asthma attacks, heart attacks, and depression. The risk of heart disease, heart attacks, and stroke is increased by certain of these medical conditions. These health issues consist of:

  • Elevated blood pressure. Your blood pressure lowers when you are sleeping normally. Your blood pressure will be higher for a longer time if you have sleep issues. One of the major dangers for heart disease and stroke is high blood pressure. One in three individuals in America, or 75 million people, have excessive blood pressure.
  • Diabetes type 2. Diabetes is a condition that can harm your blood vessels because it causes blood sugar levels to rise. According to several research, having adequate restful sleep may enhance people’s ability to control their blood sugar.
  • Obesity. Unhealthy weight gain might be a result of sleep deprivation. Children and teenagers need more sleep than adults do, therefore this is particularly true for them. Lack of sleep may have an impact on the area of the brain that manages hunger.

How Sleep Deprivation Affect Heart Health?

There is strong evidence that sleep disorders, such as sleep deprivation and fragmented sleep, are harmful to heart health.

The body needs time to rest in order to heal itself. The non-rapid eye movement (NREM) sleep stages are characterised by a slowed heart rate, decreased blood pressure, and stable breathing. These modifications lessen the heart’s workload, allowing it to recover from the strain it experiences while awake.

Without enough sleep each night, a person doesn’t spend enough time in the deep NREM sleep stages that are good for the heart. Those who experience frequent interruptions to their sleep may experience the same issue.

Chronic sleep loss has been associated with a variety of cardiac issues, including high blood pressure, high cholesterol, heart attacks, obesity, diabetes, and stroke.

Blood pressure during sleep

Blood pressure decreases by about 10% to 20% when you sleep normally and healthily. Research has shown that this practise, known as nocturnal dipping, is important for cardiovascular health.

Poor sleep is linked to non-dipping, which is when a person’s blood pressure doesn’t drop at night due to lack of sleep or sleep interruptions. According to studies, having high nocturnal blood pressure is associated with generalised hypertension (high blood pressure).

In fact, studies have shown that high blood pressure during the night is much more indicative of heart issues than high blood pressure during the day. Non-dipping has been linked to an increased risk of heart attack and stroke. Reduced blood supply to the brain and kidney issues have also been connected to it.

Many studies have shown that sleep loss has the effect of raising daytime blood pressure, however not everyone is affected equally. In middle-aged people, the connection between sleep deprivation and high blood pressure is strongest. Individuals who have other hypertension risk factors, work long hours in stressful occupations, or have chronically poor sleep patterns are more likely to have elevated blood pressure.

Coronary Heart Disease and Sleep

The most common cause of death in the US is coronary heart disease. It is sometimes referred to as coronary artery disease and occurs when atherosclerotic atherosclerosis, or plaque buildup in the arteries, causes them to harden and narrow. The heart’s capacity to receive enough blood and oxygen is decreased as a result.

Lack of sleep has been linked to atherosclerosis, according to research. White blood cells, which are produced by the immune system and accumulate in the arteries as a result of inflammation, lead to the formation of plaque. Chronic inflammation is sparked by a lack of sleep, and this chronic inflammation makes the arteries harder and leads to plaque buildup.

It is also thought that the effects of sleep on blood pressure affect how sleep loss affects coronary heart disease. The arteries are strained by hypertension, which reduces their ability to carry blood to the heart and makes heart disease more likely.

Heart failure and sleep

Heart failure occurs when there is insufficient blood flow from the heart to provide the body with the oxygen and blood it requires to function. Strong correlations between sleep issues and heart failure were observed in an observational research including more than 400,000 persons.

People in that study had a higher chance of developing heart failure if they slept for fewer than seven hours per night. Heart failure was also more prevalent in individuals who had other signs of poor sleep, such as symptoms of insomnia, daytime sleepiness, snoring, and an evening personality. One’s risk of developing heart failure increases with the number of these symptoms of poor sleep they experience.

A Heart Attack and Sleep

When the blood supply to the heart is cut off, a heart attack—also referred to as a myocardial infarction—occurs. Due to the harm that results from the heart not receiving enough oxygen, heart attacks are sometimes fatal.

Lack of sleep increases the risk of heart attacks. According to one study, those who slept for fewer than six hours per night had a 20% increased risk of having a heart attack. NREM sleep aids the heart in slowing down and recovering, whereas REM sleep is more stressful and active. The balance of these stages can get off if you don’t get enough sleep, which raises your risk of having a heart attack.

Heart attacks may occur if sleep disturbances occur, according to some research. Frequent sleep disturbances can create cardiac stress and may result in a heart attack because both heart rate and blood pressure might suddenly jump upon awakening.

Stroke and sleep

A stroke occurs when the brain’s blood supply is interrupted, depriving brain cells of oxygen and resulting in cell death. Ischemic strokes happen when an artery is blocked by a blood clot or plaque. A mini-stroke, also known as a transient ischemic attack (TIA), merely includes a momentary blockage.

Lack of sleep has been linked in studies to a higher chance of suffering a stroke. Lack of sleep raises blood pressure, and high blood pressure is thought to be the main contributor to stroke risk. Insufficient sleep may also make it simpler for blockages to happen and result in mini-strokes or strokes by promoting the building of plaque in the arteries.

Sleep and Heart Rate

The heart rate normally decreases throughout NREM sleep stages and then increases as you get ready to wake up.

A poor night’s sleep, particularly sudden awakenings, can cause a sudden increase in heart rate. According to research, those who have trouble sleeping are more prone to experience irregular heartbeats. These factors suggest that sleep deprivation and heart palpitations may be related.

Also, a research of senior citizens revealed that those who frequently experience nightmares are far more likely to report having an abnormal pulse. When a person’s sleep is disrupted by a nightmare, their heart rate may rise, and they may awaken feeling as though their heart is racing.

Chest Pain and Sleep

There are several causes of chest pain. Angina is a type of chest pain brought on by inadequate blood flow via blood arteries. Heart problems are unrelated to non-cardiac chest pain, such as heartburn or a muscle injury.

Studies have found a link between sleep deprivation and chest discomfort, and they also show that when sleep is disrupted, a fast rise in blood pressure and heart rate can result in angina.

Even non-cardiac chest pain may be related to sleep. Sleep disturbances are a common symptom of heartburn and acid reflux, which may increase the likelihood that these people will experience chest pain in the middle of the night.

Undiagnosed chest discomfort and poor sleep have also been linked in numerous studies. High incidence of symptoms like sleeplessness are present in those with persistent, unexplained chest discomfort. This connection may be related to stress and anxiety, including panic attacks, which are emotional responses that may be more frequent in persons with poor sleep, however its exact nature is unknown.

Do we actually need more sleep in the winter?

Do we actually need more sleep in the winter?

Comments 0 Comment

A vital part of wellbeing is sleep, and getting enough of it helps the body heal and function normally. According to a recent study, people get more REM sleep in the winter, which is an essential part of the regular sleep cycle.

To corroborate the results of this study in the broader population, more data is required. Yet, people can make efforts to encourage sound sleep during the winter, a season in which doing so may be particularly important.

Everyone requires sleep, yet everyone’s demands are different. Research is ongoing to determine what influences sleep requirements and the most effective course of action.

A recent study examined how seasonal changes in sleep patterns. The researchers discovered that REM sleep is more prevalent during the months of winter.

Human sleep study

The research team enlisted 292 patients to take part in sleep studies termed polysomnographies, which are conducted on individuals who have trouble falling or staying asleep.

The volunteers visited a specialised lab where they were instructed to go to sleep naturally, without setting an alarm, so that the duration, kind, and quality of their sleep could be observed.

Although sleep issues may have affected the results, the study’s design allowed for a sizable group to be evenly distributed throughout the year, which helped to better show variations from month to month.

Those who took sleep-related medications, those who experienced technical difficulties during the polysomnography, and participants whose REM sleep latency was greater than 120 minutes—which suggested that the initial REM sleep episode had been skipped—were excluded from the study.

There were 188 subjects left after the exclusions. The majority of their diagnoses exhibited little seasonal variation, while sleeplessness was more frequently identified as the year’s end approached.

Importance of REM sleep

Several facets of life, including physical, emotional, and mental health, are impacted by sleep. Sleep duration and quality have an impact on bodily functions like immune system, metabolism, heart health, and memory.

The several stages of sleep that people go through are all necessary for a restful night’s sleep.

Rapid eye movement (REM) sleep is one type of sleep. The brain is more active during REM sleep, and dreams are experienced. REM sleep is beneficial for controlling mood. Moreover, it enhances immunological performance, focus, and memory.

According to the results of this latest study, there may be seasons of the year when people experience more REM sleep.

M​ore REM sleep in the winter

This specific study focused on variations in seasonal sleep patterns. All through the year, researchers examined the subjects’ sleep patterns. The individuals were already dealing with some sleep abnormalities, such as insomnia and sleep-related respiratory issues.

When conducting their analysis, the researchers used 188 participants. Participants were monitored while they slept using a method known as polysomnography.

Participants were encouraged by the researchers to stick to their usual bedtime routines. Alarm clocks were not allowed to be used by participants. Participants were disqualified from the study based on a few important factors, such as the usage of sleep-interfering drugs.

To Medical News Today, research author Dieter Kunz provided the following significant findings:

“In our work, we demonstrate that, in an adult population residing in an urban environment, human sleep architecture differs significantly across seasons. In a sizable population with neuropsychiatric sleep disorders, we employed polysomnography to record the various stages of sleep over the course of a full year.

According to Kunz, they discovered three intriguing findings:

  • In comparison to summer, people slept an hour more during the winter.
  • I had about 30 minutes more of REM sleep in the winter than the spring.
  • Got 40 minutes fewer of deep sleep in the fall than the other months.

Researchers found no statistical significance in the one-hour sleep gap between the winter and summer seasons. Instead, one of their key areas of interest was the seasonal variations in REM sleep.

Get better sleep in the winter

The American Board of Sleep Medicine-certified sleep specialist Nicole Eichelberger focuses on abnormalities of the circadian rhythm, apnea, and insomnia. Eichelberger gave us some advice for getting a good night’s sleep, which included maintaining a consistent sleep routine.

Even on weekends, try to go to bed and wake up at the same time every day, she advised.

Making a sleep-friendly environment is also beneficial.

Ensure that your bedroom is cold, quiet, and dark. Utilize supportive bedding and soft pillows, advised Eichelberger.

Restrict your screen time before bed.

It can be more difficult to fall asleep due to the blue light emitted by electronic gadgets, according to her. Melatonin is a hormone that promotes sleep.

Avoid alcohol and caffeine.

Both can interfere with your sleep and make it more difficult to get enough rest, she explained.

Develop your relaxing skills.

You can relax and be ready for sleep by engaging in activities like yoga, deep breathing, or meditation, according to Eichelberger.

She continued by saying that sleep is essential for both our physical and mental health because it aids in both memory consolidation and learning as well as body recovery and repair.

Persistent sleep loss has been connected to a number of health problems, including as obesity, diabetes, and heart disease, she said. “On the other side, it has been demonstrated that getting adequate sleep strengthens our immune system, lifts our mood, and improves our cognitive performance. Simply put, having enough good sleep is crucial for our overall health.

Irregular sleep habits may increase atherosclerosis risk.

Irregular sleep habits may increase atherosclerosis risk.

Comments 0 Comment

According to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association, irregular sleep patterns, such as sleeping fewer or more hours each night and going to bed at various times, may put adults over 45 at an increased risk of developing atherosclerosis.

A recent study investigates the relationship between irregular sleeping patterns, atherosclerosis, and not keeping a regular bedtime.

The study discovered that older persons were much more likely to experience subclinical symptoms of atherosclerosis. Only if their sleep patterns altered by an average of two hours over the course of a single week and by an hour and a half.

What is Atherosclerosis?

When you have atherosclerosis, the interior of your arteries develop sticky plaques made of cholesterol, fatty deposits, and cell waste products from your blood. As a result, the plaques thicken and sometimes even harden the arterial walls. The illness restricts blood flow, making it difficult for your organs to receive enough oxygen.

According to the National Institutes of Health (NIH) of the United States, the disease associated with atherosclerosis is the country’s top cause of mortality. Also, it affects 50% of Americans between the ages of 45 and 84.

Study on sleep and disease risks

MESA (Multi-Ethnic Study of Atherosclerosis), a different community-based study, involved 2032 participants in the study. The goal of MESA was to examine the features and risk factors of subclinical atherosclerosis symptoms in a variety of senior citizens.

In light of this, slightly more than half of MESA participants were female. Participants self-identified as White in 38% of cases, Black or African American in 28%, Hispanic in 23%, and Chinese in 11% of cases. They came from a variety of geographical locations, including St. Paul, Minnesota; Baltimore City and Baltimore County. Also, Maryland; Chicago, Illinois; Forsyth County, North Carolina; Los Angeles County, California; Northern Manhattan; and the Bronx, New York.

The participants’ ages, which ranged from 45 to 84 with an average of 69, were all within the normal range for cardiovascular disease. During seven days, each participant wore a wristwatch that recorded when they were awake or slept. They also finished keeping sleep logs.

Last but not least, each person took part in a single night of in-home sleep monitoring that recorded their breathing, heart rate, sleep phases, and length.

In the current study, person with irregular sleep patterns were 1.33 times more likely to have high coronary artery calcium. This is compared to those with more regular sleep duration variations, which varied by an average of two hours per week. Moreover, they had a 1.75 times higher likelihood of having abnormal ankle brachial indices.

Researchers discovered a 1.39 times greater chance of calcified arterial plaques in patients whose bedtimes changed by an average of 90 minutes over the course of a week.

The connection between sleep and atherosclerosis

The circadian rhythm, a 24-hour internal clock in our bodies, controls a variety of physiological activities. This includes sleep-wake cycles. We can experience what is known as “social jet lag” when we frequently go to bed and wake up at different times. According to Dr. José M. Ordovás of Tufts University, who was not involved in the study. This can disturb our circadian rhythm.

Dr. Hoang Nguyen is an interventional cardiologist who was not engaged in the study. He told Medical News Today:

The scientists hypothesised that irregular sleep patterns encourage cardiovascular disease by interfering with the body’s normal circadian cycle. This in turn affects inflammation, glucose metabolism, and sympathetic neurohorma. Cardiovascular disease is known to be brought on by each of these variables.

According to Dr. Ordovás, “the sympathetic nervous system (SNS) activity is normally lowered during sleep. This allows the body to relax and recuperate.” On the other hand, he continued, “Sleep problems, such as sleep apnea, can result in increased SNS activity, which can produce hypertension and other CVD risk factors.

According to the press release, the researchers were unable to determine “whether increased sleep irregularity increases the development of atherosclerosis” . However, sleep and atherosclerosis could not be evaluated concurrently.

Too little sleep, too much, and just right

Dr. Full added that no differences were found in the atherosclerosis indicators of the participants in their study, which followed individuals who frequently slept more or less than usual. Like all other people, older individuals should receive between seven and nine hours of sleep per night, according to the NIH.

Some studies have shown that too much sleep might be harmful. Both a short sleep duration of less than 7 hours per night and a lengthy sleep duration of more than 9 hours per night have been linked to an elevated risk of CVD, according to Dr. Ordovás.

The authors of this study “went beyond the quality of sleep, and evaluated the regularity of sleep,” which is interesting, according to Dr. Nguyen.

Challenges of Insomnia in an individual’s life.

Challenges of Insomnia in an individual’s life.

What is Insomnia?

Millions of individuals all around the world constantly experience insomnia, a sleep problem. A person with insomnia has trouble getting to sleep and staying asleep. Depending on their age, adults, according to the Centers for Disease Control and Prevention (CDC), require between 7-9 hours of sleep every night.

According to research, 25% of Americans report having insomnia each year, although 75% of these people do not go on to have a chronic condition. Short-term insomnia can cause daytime weariness, attention problems, and other issues. Long-term, it could raise the risk of contracting certain illnesses.

An insomniac has trouble getting to sleep or staying asleep. They might often get up too early.

This may result in problems like:

  • Lethargy and tiredness during the day
  • an overall sense of being physically and mentally ill
  • anxiety, impatience, and changes in mood

Additionally, the aforementioned problems may be causes, effects, or both of insomnia.

In addition, chronic illnesses like the following may be influenced by insomnia:

  • obesity
  • diabetes
  • a cardiovascular condition
  • depression

It can also impair a person’s effectiveness at work and school and restrict their capacity to carry out daily tasks.

Causes of insomnia

There are many different medical and psychological causes of insomnia. Frequently, a transient issue, such as transient stress, is the root reason. In certain other cases, an underlying medical problem is the cause of the sleeplessness. Typical causes include

  • dealing with any additional adjustments to the body’s internal clock, such as jet lag, shift changes at work, or other circumstances
  • If it prevents sleep, it could be the bed being uncomfortable, the room being too hot, cold, or noisy, or taking care of a family member.
  • getting insufficient exercise
  • experiencing nightmares or nocturnal terrors
  • utilising drugs for fun, such cocaine or ecstasy

Some people experience insomnia as a result of stress or a mental health condition. A person might be going through:

Other medical disorders that may interfere with sleep include:

  • Irritable bowel syndrome
  • excessive thyroid activity
  • nap apnea
  • GERD, also known as gastroesophageal reflux disease
  • COPD, also referred to as chronic obstructive pulmonary disease
  • chronic pain

Sleeping problems are frequently caused by signs of various health problems or by changes in the natural world. For instance, hormonal changes during menopause might cause night sweats, which can keep you awake. Sleep patterns are disturbed or altered in patients with Alzheimer’s disease due to abnormalities in the brain.

Additionally, some people experience fatal familial insomnia, a rare genetic disease that makes it difficult to fall asleep and may possibly be fatal.

Symptoms of insomnia

In addition to interrupted sleep, insomnia can result in various problems, including:

  • daytime drowsiness or weariness
  • irritation, sadness, or worry
  • signs of the digestive system
  • low dynamism or motivation
  • insufficient focus and attention
  • an absence of coordination that results in mistakes or accidents
  • anxiousness or fear about sleeping
  • using sleeping pills or booze
  • stress headaches
  • having issues working, learning, or socialising

According to experts, sleep deprivation is a major contributing factor in car accidents.

Types of insomnia

Depending on the duration, insomnia can be categorised as follows:

  • A short-term issue is acute, brief sleeplessness.
  • It may take months or years to overcome chronic insomnia.

The causes are also classified by doctors:

  • A problem in and of itself is primary insomnia.
  • Secondary insomnia is brought on by another medical condition.

They also categorise it according to severity:

  • Mild insomnia is characterised by a lack of sleep that causes fatigue.
  • Daily functioning may be impacted by moderate insomnia.
  • Life is significantly affected by severe sleeplessness.

When determining the kind of insomnia, doctors also take into account additional variables, such as whether the patient regularly wakes up too early or experiences difficulty:

  • a sound slumber
  • remaining in bed
  • getting quality sleep

Treatments

Depending on the underlying issue and the type of insomnia, several approaches may be best, however some possibilities include:

  • counselling
  • CBT stands for cognitive behavioural therapy.
  • medicines on prescription
  • several over-the-counter sleep aids that can be purchased online
  • Melatonin, which can be purchased online as well

Melatonin may promote sleep, however there isn’t enough convincing evidence to support this claim.
