Researchers from Keele University in the UK conducted research related to the characteristics of sleep of different durations..

3 million people were studied in the period from 1970 to 2017. Studies have concluded that prolonged sleep (more than 8 hours per night) seriously increases the risk of premature death.. Study results published in Journal of American Heart Association.

People who sleep for a long time have a 44% increased risk of developing various diseases of the cardiovascular system. They are also more likely to show signs of apnea, when the breathing of a sleeping person is temporarily interrupted.. In some cases, such respiratory arrest can even lead to death..

If people slept less than seven hours a day, the researchers did not reveal a difference in the frequency of developing dangerous diseases associated with the risk of premature death in comparison with people who slept for eight hours..

Similar studies on the harmful effects of “oversleeping” on human health were conducted by employees of the University of Massachusetts. They studied more than 2 million people from different countries who liked to sleep for a long time on weekends.. Scientists have concluded that sleeping more than 8 hours leads to an exacerbation of chronic diseases and increases the likelihood of premature death in people under 65 years of age..

Scientists explain this by a syndrome that is similar to the state of a person when changing time zones.
