A group of scientists under the leadership of Chun Shing Kwon from Kolskogo University (UK) concluded that long sleep causes heart problems and increases the risk of premature death. This publication reports Science Alert.

Experts analyzed 74 studies encompassing more than three million participants. It turned out that sleep for ten hours a day increases the likelihood of death by 30 percent compared to seven hours per day. The risk of death from stroke increased by 56 percent and 49 percent, from cardiovascular diseases. Poor sleep is also associated with health problems and increases the risk of heart disease by 44 percent.

At the same time, scientists note that the obtained results have some limitations. So, long sleep may not be the immediate cause of death, because in some cases excessive sleepiness in itself is an alarming symptom. However, the researchers recommend to reduce the duration of a night’s rest of 7-8 hours a day to reduce the risk of serious diseases.

In June 2018 Japanese scientists published a paper in the Journal of the American Geriatrics Society, which reported that too short and too long sleep increases the risk of dementia and premature death in people older than 60 years.

In may 2018 was published an article of scientists from Stockholm University in Sweden, which found that long sleep at the weekend may compensate for the lack of it in everyday life to prevent the related disease, and reduce the risk of premature death. In this case, for people over 65 years of age is enough to more short NAPs.
