Although sleep is a vital process for the health of the body, there are a number of factors that make sleep useful to the body. In the event of a failure of any of these factors, the body of sleep suffers, including the prevalence of sleep and the increase in the number of hours, as confirmed by the following study:
The effect of sleep overload on health:
NEW YORK (Reuters Health) – Sleeping more than 8 hours a day is associated with an increased risk of death and cardiovascular disease, according to a recent study published in the European Journal of Cardiology.
But one of the possible reasons is that people have underlying conditions that make them sleep longer, which can increase the risk of cardiovascular disease or death, explain the authors of the study.
Details of the study:
The study found that, based on data from 21 countries in seven different geographic regions, the team found that people who slept more than the maximum recommended limit increased the risk of serious cardiovascular disease, such as accidents. cerebrovascular disorders or heart failure. Up to 41%, according to CNN.
Sleeping less than 6 hours increased the risk by 9% compared to people sleeping between 6 and 8 hours, but this conclusion was not considered statistically significant.
The team found that for every 1,000 people sleeping at the recommended time – six to eight hours a night – 7.8 had cardiovascular disease or died each year and that number was 9.4 in people sleeping six hours or less each night.
