A new study published in the scientific journal European Heart Journal Digital Health and by Harvard University showed that sleeping between 10 PM and 11 PM is an ideal time for healthier sleep.
In the research, it was found that at this time the risks of developing heart diseases decrease because people sleep better. And how was this done?
The tests involved more than 88,000 individuals aged between 45 and 79, whose sleep was monitored for a week through devices placed on their wrists. It was found that those who went to bed later - at midnight - could have up to 25% higher chances of developing cardiovascular diseases, and those who started sleeping before this time, 24%. The authors showed that going to bed at unconventional times alters the circadian rhythm, which is essential for regulating the vital functions of the body.
According to pulmonologist and Sleep Medicine Specialist, Jessica Polese, in fact, the later a person goes to sleep, the less sleep time they will have, or sleep deprivation may occur, which poses a risk for cardiovascular diseases.
“Heart diseases such as heart attack and stroke can occur without quality sleep. A poorly slept night can cause obesity, increased blood pressure, cholesterol, and stress itself, and this is a reflection of all these ailments that affect heart health,” explains the doctor.
“The quality of nighttime rest and cardiovascular health are related, and studies serve to prove this factor. The novelty was the issue of a fixed time that we can verify,” points out Jessica.
The doctor emphasizes that the ideal sleep duration today varies from six to eight hours of sleep.
