A new study on sleep and its habits has a clear message for those who want to lower their risk of major cardiovascular problems, such as heart attack or stroke: stick to a regular sleep schedule.

While research often focuses on quality and duration, researchers from the University of Oulu in Finland found that going to bed at the same time every night is just as important. important, especially if you don’t sleep more than eight hours.

Researchers measured the activity of 3,231 individuals aged 46 through the devices over a week. When participants who slept less than eight hours were divided into groups (regular, fairly regular, and irregular), the data showed that those in the irregular group had twice the risk of a serious cardiac event over the next decade, compared to those who slept regularly.

Also, it was found that more variability in the “midpoint” of sleep (between the time you go to bed and wake up) was also associated with worse health. heart.

Researcher Laura Nauha, explains that regularity reflects the rhythms of daily life. However, there is a caveat: this risk only appeared in those who slept less than the average amount (eight hours).

Sufficient sleep appears to help protect against the negative effects of an irregular schedule. Interestingly, the wake-up time did not seem to matter. The link only existed for large variations in bedtime.

In the group with an irregular sleep pattern, the average variability during the week was 108 minutes, compared to just 33 minutes in the regular group.

Scientists think that our circadian rhythms – the body’s natural twenty-four-hour cycles – explain the link. Constantly changing schedules disrupts these rhythms, not allowing the heart proper periods of rest and recovery.

Also, real-world factors such as work stress and mental health play a role. Cardiovascular disease remains the leading cause of death globally, with almost 18 million deaths per year.

The findings of this study, published in BMC Cardiovascular Disorders, remind us that the stability of our routine is a powerful tool for preventing serious diseases. /tesheshi.com/
