Even though we’ve all heard about the advantages of getting a good night’s sleep, recent research indicates that regular sleep patterns, rather than just sleep duration, may help lessen the risk of a heart attack.
A recent study: Adults with irregular sleep habits have an increased chance of developing cardiovascular disease, according to a reliable source (CVD). Lack of a regular bedtime or wake-up time was used to describe an irregular sleep pattern. The National Heart, Lung, and Blood Institute study discovered that older persons’ inconsistent sleep patterns may be a separate CVD risk factor.
Researchers monitored 1,992 males and females, aged 45 to 84, without CVD throughout the course of five years. These adults came from a variety of ethnic groups and resided all around the country.
The patients wore actigraph wristband devices to track their sleep and wake activity for 7 days straight to measure their sleep irregularity.
A further 5-year follow-up period revealed that 111 participants experienced CVD events. Heart attack, stroke, and even CVD-related death are included in this.
Inflammation and sleep
It is already commonly acknowledged that sleep deprivation causes inflammation and blood sugar fluctuations, among other health problems.
The Centres for Disease Control and Prevention (CDC (Centers for Disease Control)) recommends that adults get at least 7 hours of sleep each night. Lack of sleep has also been associated with a higher risk of obesity, diabetes, and heart disease in earlier research. For instance, according to the Sleep Foundation, those who do not get enough sleep are more likely to develop coronary heart disease and cardiovascular disease, regardless of their age, weight, or lifestyle.
According to the CDC, most adults require at least 7 hours of sleep per night to keep their hearts healthy, as well as to ward off depression, type 2 diabetes, and high blood pressure.
This study differs from previous ones in that irregular sleep patterns were considered in addition to sleep time, and it was found that variability is a significant influence on heart health.
According to the study report, participants with the least regular sleep duration or timing had more than twice as high a risk of experiencing a CVD event during the follow-up period as those with the most regular sleep patterns.
The underlying processes connecting irregular sleep with CVD are still unknown. Numerous causes, including metabolic abnormalities linked to obesity, diabetes, and high cholesterol, are under investigation, according to the researchers.
Inflammation can be triggered by anything that interferes with the circadian rhythm, or sleep cycle, of the body. It is also stated that irregular sleep patterns increase artery development and inflammation, which can disrupt the cholesterol plaque in our arteries and cause a heart attack. A hormone called leptin is reduced in persons who have sleep disorders. This hormone alerts us to our fullness and advises us to stop eating, he explained. We eat more and move less when leptin levels are low, which causes weight gain, obesity, and insulin resistance, which is an inflammatory condition. Creating a vicious cycle raises the risk of cardiovascular problems.
Biomarkers of good health:
Despite this, there is still much to discover. Future studies, according to the researchers, will explore blood biomarkers that could shed light on the connection. Additionally, longer follow-ups are required. People will gain knowledge about how to control their sleep habits as a result.
As stated in the original article, the study has certain limitations, such as small sample size and a brief follow-up period. Another drawback is that the authors combined a variety of endpoints, including heart attack, stroke, and other occurrences; larger research would have shown more conclusive results. A healthy sleep schedule may be just as crucial as medical therapy and represents an additive advantage to medication to lower the risk of a heart attack.
It will be crucial to examine biomarkers, such as blood pressure fluctuations, inflammatory indicators, and hormone level variability.
Sleep issues and cardiovascular health
Numerous studies have linked disturbed sleep to an increased risk of heart illness. The two most prevalent sleep disorders, insomnia, and obstructive sleep apnea (OSA), influence both the quantity and quality of sleep, which influences cardiometabolic health. OSA is a severe sleep disorder in which the tongue or throat tissues repeatedly block the airway, causing breathing to halt or shallower. It is predicted that 10% to 25% of individuals may be affected. Another typical sleep disorder is insomnia, which is thought to affect up to 25% of adults yet typically goes misdiagnosed. Everyone with heart failure and atrial fibrillation should be screened for OSA, according to the American Heart Association (AHA).
Poor sleep results in unwise food decisions
Researchers recently examined the association between sleep and eating habits in 500 women for a study that was recently published in the Journal of the American Heart Association. The ladies provided information on the quality of their sleep, how long it took them to fall asleep, and whether they experienced insomnia. They disclosed their eating patterns as well.
According to the study, women who slept poorly ingested more added sugars than those who slept well. Women who took longer to fall asleep ate more food in general and more calories. Additionally, women who had trouble sleeping were more prone to overeat and choose unhealthful foods. It is well-recognized that a poor diet raises the risk of cardiovascular disease (CVD).
We cannot infer causal relationships from the data in this observational study. We can infer that sleep deprivation affects how content or full we feel, through intricate hormonal signaling. We can also think about how a bad diet (consuming an excessive amount of the wrong foods) may interfere with our ability to go to sleep and stay asleep. In addition, a poor diet and binge eating are linked to obesity, a significant CVD risk factor.
Heart health benefits of a regular bedtime and consistent sleep length
Another recent study found a connection between irregular sleep patterns and the emergence of CVD, which was published in the Journal of the American College of Cardiology. This investigation followed approximately 2,000 healthy adult men and women for five years. Participants wore wristbands to monitor their sleep and other activities. Participants in the study also underwent a thorough sleep analysis and provided information about their daily lives, including their diets.
According to research, irregular sleep patterns raise the risk of heart disease. Comparing individuals with less variation in sleep duration and more regular bedtimes, those with the highest risk of getting heart disease had a risk of heart disease that was more than twice as high. The risk of CVD is thought to be impacted by several metabolic abnormalities, including obesity, diabetes, and high cholesterol, which are all linked to irregular sleep patterns. Additionally, because sleep may have an impact on our metabolic health, eating habits may be even more crucial when we are sleep deprived.
Put sleep first for better heart health
There is mounting proof that getting enough sleep is essential for good health. The significant issue of how sleep impacts our nutrition and cardiovascular health is brought up by these two recent research.
Keep track of how much and how soundly you sleep at night. Consult your doctor if you struggle with insomnia or poor sleep quality to learn more about formal sleep studies and possible sleep-enhancing factors.
