Sleep is the best way to relax and rejuvenate your body. It is what eliminates all the physical and mental stressors and reduces the risk of developing various illnesses, including cardiovascular complications. That said, while for some, bedtime starts as and when they fall off to sleep, research suggests that there could be an optimal time to go to bed so as to ensure a healthy heart.

The study

According to a recent UK study, sleeping between 10 p.m. and 11 p.m. is the best time for heart health. The new research published in the European Heart Journal, collected data from more than 88,000 participants aged 43 to 79 in the U.K. Biobank study, who agreed to monitor their bedtime and wake-up time over a 7 days using an accelerometer.

Additionally, the volunteers underwent various physical, demographic, lifestyle and health assessments.

The study found that people who went to bed before 10 p.m. and later than 11 p.m were associated with a greater risk of developing cardiovascular disease than those who went to sleep between 10-11pm. Also, the association between bedtime and the risk of developing heart diseases was higher among women.

Sufficient sleep and proper bedtime are key to a healthy body

Sleep deprivation has often been linked to health conditions such as hypertension, obesity and diabetes. Therefore, researchers in the past have emphasized on the need for at least seven to eight hours of sleep daily.

Similarly, the most recent finding suggests a possible link between sleep onset and cardiovascular risk.

Dr. David Plans, the author of the study and a senior lecturer in organizational neuroscience at the University of Exeter says, “Our study indicates that the optimum time to go to sleep is at a specific point in the body’s 24-hour cycle and deviations may 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 adds.

Furthermore, he explains how optimum bedtime fits well with circadian rhythms and daylight exposure. “While we cannot conclude causation from our study, the results suggest that early or late bedtimes may be more likely to disrupt the body clock with adverse consequences for cardiovascular health,” elaborates Dr. Plan.

However, the 10 p.m. to 11 p.m. ideal sleep window might not apply for everyone, demanding more research.

According to Dr. Sanjay Bhat, Senior Consultant – Interventional Cardiology, Aster CMI Hospital, Bengaluru says that there is no such thing as the right time to sleep.

“A proper 8 hours of uninterrupted sleep is vital for a healthy heart and healthy functioning of the body,” he says. Furthermore, one should not consume alcohol or pop sleeping pills to help sleep better. If someone is experiencing insomnia or frequently getting up or breathing issues during the night, it is recommended to seek immediate medical help or advice, he elaborates.
