Too much sleep at night, no exercise during the day, sedentary, beware of the risk of early death. A new study from Australia found that if a person sleeps more than nine hours at night and lacks exercise during the day, often sedentary, the risk of early death will increase. In this study, too little exercise means less than 150 minutes of exercise a week, and too much sedentary time means sitting for more than seven hours a day. Researchers at the University of Sydney analyzed information on more than 230,000 people over the age of 45 owned by the Sachs Institute in Australia and analyzed the association between their lifestyle habits and disease. The findings showed that long sleep, sedentary lifestyle and lack of exercise all increase the risk of early death, while smoking, heavy alcohol consumption and sleeping less than seven hours a night also increase the risk of early death. The researchers further analyzed and found that not exercising plus sleeping too much, not exercising plus being sedentary, and smoking plus drinking a lot of alcohol doubled the risk of early death.
