A study in the United States found that if elderly women sit in a chair for more than 10 hours every day and seldom exercise or move, the cell aging rate will be faster. Compared with older women who exercise regularly, the cell aging rate of inactive people is 8 years earlier. Sitting too long, less exercise, shorter DNA telomeres, the research team of the University of California, San Diego recently published the above research results in the American Journal of Epidemiology. Studies have shown that when elderly women do moderate or strenuous exercise for less than 40 minutes every day and sit still for more than 65,438+00 hours every day, the "telomere" of cell DNA will become shorter, which means that cell aging is more serious. The more cells age, the shorter telomeres are. Telomeres are located at the end of cell DNA, just like the plastic sleeve at the front of shoelaces, which can protect chromosomes. As cells age, telomeres will gradually shorten and wear. Healthy living habits such as obesity and smoking will accelerate telomere shortening, which may be closely related to cardiovascular diseases, diabetes and major cancer diseases. The main author of this study is Aladdin, a scholar in the Department of Family Medicine and Public Health at the University of California, San Diego. Friedrich Hirth Jaap said that a person's physical age does not necessarily match his actual age. This study found that if his normal living habits are static and rarely active, the cell aging rate will accelerate. Regular exercise helps to stay young and healthy. This study included nearly 65,438+0,500 women aged 64 to 95 in the American Women's Health Advocacy Study (WHI). These women filled out questionnaires when they participated in the study, so that researchers could understand their exercise and sleep habits. Friedrich Hirth Jaap pointed out that research shows that if sedentary women follow the advice and guidance of national health units and spend at least 30 minutes exercising every day, telomere shortening will not accelerate. It can be seen that exercise helps to keep young. It is suggested that people should incorporate exercise into their living habits. Even the 80-year-old people should exercise regularly, so that their bodies will be healthy and full of vitality.
