What if going to bed early was enough to improve heart health? In any case, that’s what a new study by British researchers suggests.
With the fast pace of modern life, it can be difficult to go to bed at the same time every night. But a new study highlights the importance of going to bed between 10 p.m. and 11 p.m., along with a regular bedtime, to protect heart health.
For this study, scientists examined the relationship between sleep time and heart disease with a sample of more than 88,000 adults with an average age of 61 years. Data on sleep onset and wake time were collected over seven days using an accelerometer worn on the wrist. Participants also completed questionnaires and demographic, physical and lifestyle assessments.
During the five-year follow-up, about four percent of participants developed heart disease, and the incidence was highest among those whose sleep time was midnight or later and lowest among those whose sleep time was past 10 p.m. It was between 10.59 hrs.
Responding to these findings, Dr David Planes from the University of Exeter said he suggests that sleeping early or late is more likely to disrupt the body clock, leading to adverse effects on heart health. “Our study indicates that the optimal time to sleep occurs at a specific point in the body’s 24-hour cycle and that this deviation can be detrimental to health. The riskiest time was after midnight, potentially because it may reduce the likelihood of seeing morning light, which resets the body clock,” he remarked, before continuing, “Although the results do not show a causal relationship, sleep timing emerged as a Potential cardiovascular risk factors, independent of other risk factors and sleep characteristics. If our results are confirmed by further studies, sleep synergy and basic sleep hygiene may be an inexpensive public health goal to reduce heart disease risk. It is possible. “
The full results of the study were published in the European Heart Journal – Digital Health.
