A meta-analysis conducted by researchers from Tongji Medical College of Huazhong University of Science and Technology and School of Public Health of Iowa University shows that people who sleep too much or too little have an increased risk of death or cardiovascular events, and those who sleep for about 7 hours a day have the lowest risk.
The results show that moderate sleep time, like reasonable diet and active exercise, can replenish energy for human body, regulate various physiological functions and reduce the risk of cardiovascular diseases. Sleeping more and sleeping less is not good for heart health. I suggest you sleep for about 7 hours every day.
Extended data:
In addition, human bone loss began at the age of 35, and the probability of postmenopausal fracture in women greatly increased, and the risk was much higher than that in men. Recently, the American Journal of Bone and Mineral Research published a new study, saying that there is an important correlation between sleep duration and the occurrence of fractures.
The University of Pittsburgh analyzed these data. The annual fall probability of women who only sleep for 5 hours every night is10.6%; The annual fall probability of women who sleep more than 10 hour is11.8%; Among women who sleep for 7-8 hours, this probability drops to 7%. In contrast, if the sleep time is too short and too long, the risk of female upper limbs, lower limbs and waist fractures will increase by about 25%.
Moreover, there are many factors that cause the elderly to fall, but we should pay attention to too little or too much sleep. Experts suggest that actively improving sleep quality is helpful to prevent fractures in the elderly.
