If you want a healthy heart, there are few better ways than to start an early night’s sleep, but not too soon. Regularly falling asleep between 10 pm and 11 pm seems to be linked to a lower risk of heart disease, according to a new study published in the European Heart Journal – Digital Health.
The study found that people who fell asleep at midnight or later had a 25 percent higher risk of cardiovascular disease, compared to falling asleep between 10 pm and 11 pm. The risk was 12 percent higher for those who slept between 11 pm and midnight. Interestingly, there was also an increased risk for those who acted very early, with a 24 percent increased risk for people who slept before 10 PM.
University of Exeter Dr. “Our study shows that the best time to sleep is at a certain point in the body’s 24-hour cycle, and deviations can be detrimental to health. The most risky time was after midnight because it could potentially reduce the likelihood of seeing the morning light, which resets the body clock,” said David Plans in a statement.
According to Dr Plans’ statement, “Although the findings did not show causation, sleep timing did emerge as a potential cardiac risk factor, independent of other risk factors and sleep characteristics. If our findings are confirmed in other studies, sleep timing and basic sleep hygiene are cost-effective to reduce heart disease risk. could be a public health target.”
The study looked at 7 days of sleep onset and wake time data collected via a wrist-worn accelerometer from more than 88,000 people participating in the UK Biobank project. Participants also filled out a questionnaire asking about their demographics, lifestyle, broader health and physical assessments. They were then followed years later for a new diagnosis of cardiovascular disease, including heart attack, heart failure, chronic ischemic heart disease, stroke, and transient ischemic attack. After taking into account other factors such as smoking status, body mass index, and socioeconomic status, the team analyzed how time to sleep onset was linked to cardiovascular disease risk.
Dr. As Plans explains, the study did not attempt to explain the potential reason behind the apparent link. However, a large body of data from previous studies highlights the link between heart health and sleep quality. Scientists don’t fully understand this relationship, but it’s likely to be related to sleep’s effect on biological processes such as glucose metabolism, blood pressure, and inflammation.
One thing that emerged in this new study was that the link between sleep onset and cardiovascular disease was more pronounced in women than in men. The reason for this is unknown, but researchers suspect it may have something to do with hormones.
Dr. There may also be a gender difference in how the endocrine system responds to a disruption in circadian rhythm. Alternatively, the older age of study participants could be a confounding factor, as women’s cardiovascular risk increases postmenopause – it’s women and men. means that there may be no difference in the strength of the relationship between
