Recently, a meta-analysis conducted by researchers at Tongji Medical College of Huazhong University of Science and Technology and the School of Public Health of the University of Iowa in the United States suggested that people who slept too much or too little would have a higher risk of death or cardiovascular events People who sleep for about 7 hours a day have the lowest risk.
Researchers searched the relevant prospective cohort studies previously published December 1, 2016 in several specialized biomedical related databases to examine the correlation between sleep time and the outcomes of the four cardiovascular events in the overall healthy population Data analysis showed that there was a U-shaped correlation between sleep time and the consequences of the four cardiovascular events, specifically a 1-hour reduction in sleep time compared to people who slept for 7 hours a day The risk of death and cardiovascular disease increased by 6%, the risk of coronary heart disease increased by 7% and the risk of stroke increased by 5%. For each hour of sleep, the risk of death increased by 13% and the risk of cardiovascular disease increased by 12% , A 5% increase in the risk of coronary heart disease and an 18% increase in the risk of stroke.
The study, published in the American Heart Association magazine, found that moderate sleep time, like proper diet and active exercise, can supplement the body's energy, regulate various physiological functions, and reduce the risk of cardiovascular disease. Sleep less, are bad for heart health, it is recommended that you guarantee 7 hours a day sleep.
