More than double the risk for people with irregular sleep – Trends Vrends

People who do not have a fixed sleeping time and sometimes sleep long, sometimes little, but also those who sleep at different times within the 24 hours have a higher cardiovascular risk.

According to a new scientific study from the USA, the risk of cardiovascular disease appears to be greater the more irregular their sleep duration is due to a disruption in the biological clock that affects metabolism, blood pressure and heart rate.

The researchers, led by Harvard Medical School and Brigham & Women’s Hospital in Boston assistant professor of sleep epidemiology Tianyi Huang, who published the related paper in the Journal of the American College of Cardiology, studied nearly 2,000 people over a five-year period Age from 45 to 84 years. Years.

Participants had no cardiovascular disease at the start of the study and were asked to wear a special sleep-tracking device on their wrist. During the study, 111 people suffered a heart attack, stroke, or other cardiovascular event.

It found that those who slept the most irregularly (at least a two-hour difference in sleep duration per night) were more than twice as likely to suffer from cardiovascular problems.

Those who had the most regular sleep patterns (difference of up to an hour from night to night) were at lower risk. The same difference in risk existed for the bedtime difference: those who swayed by at least 90 minutes from night to night were at higher risk than those who swayed no more than 30 minutes.

“When we talk about sleep, we usually focus on its duration, how many hours a person sleeps at night, rather than how irregular their sleep is, what irregular times they go to bed, and how variable their sleep durations are.” a recent evening. “Our study shows that healthy sleep is not only adequate sleep, but also sleep that is not irregular,” said Dr. Huang

Another American study conducted by Dr at regular intervals – then the risk of heart attack, stroke and other cardiovascular problems decreases.

At the same time, this helps women in particular to maintain their normal weight. Going to bed at the same time every night makes it easier to lose weight.

There is growing evidence that little, poor and irregular sleep increases the risk of heart disease, high blood pressure, diabetes, obesity, etc.

In fact, several scientists argue that sleep should now be the eighth predictor of cardiovascular health, alongside smoking, body weight, diet, exercise, cholesterol, blood pressure and sugar levels.

The second study found that people who got the healthiest amount of sleep (seven to eight hours a night) were 61% less likely to be diagnosed with a heart problem. Those who get good, regular sleep have a 59% reduced risk of heart attack or stroke and a 44% reduced risk of developing heart disease within the next five years.

Finally, a third American study led by Dr. Maurice Ohio of Stanford University in California, which was attended by almost 11,000 people and was presented at a conference of the American Academy of Neurology in Toronto, concluded that older adults may experience daytime sleepiness more often and the risk of new diseases such as diabetes, high blood pressure or develop cancer. This is especially true for older people who are sleepy during the day despite having slept at least seven hours at night.

“Focusing on sleepiness in older people can help doctors predict and prevent future illness,” Makarem said. For example, seniors with frequent sleepiness were 2.3 times more likely to develop diabetes or high blood pressure, 2.5 times more likely to develop heart disease, and risk of developing cancer, according to the study three years twice as high.
