What precautions should the elderly pay attention to when exercising in the morning in winter?

　　Foreign scientists are working on a healthy elderly A study on blood pressure changes in winter and summer among young people found that in winter, the systolic blood pressure and diastolic blood pressure of the elderly were higher than those of the young. Comparing alone, the blood pressure of the elderly in winter is consistently higher than that in summer, while the comparison between winter and summer blood pressure of young people is meaningless. Blood pressure in the elderly and young groups showed an increase in the morning, a variable plateau during the day, and a decrease at night. There were no seasonal differences in nighttime blood pressure between the two groups. It was also found that the blood pressure of the elderly showed significant differences every hour (including 9:00-12:00 and 22:00-23:00) in winter and summer, but there was no such phenomenon in the blood pressure of young people.

　　Researchers believe that the blood pressure of the elderly in winter is higher than that in summer. In particular, the blood pressure in the early morning and morning in winter is higher than in summer. This is mainly related to the increase in physical activity of the elderly in the morning in winter. It is also related to the low indoor and outdoor environmental temperatures in winter and the reduced defense ability of the elderly against cold. acute cardiovascular disease in the elderly disease The changes in the circadian rhythm that occur are consistent with the increase in blood pressure, especially the rhythm of the increase in blood pressure in the morning and evening to before going to bed, which suggests that the increase in blood pressure in the morning in the elderly in winter is potentially dangerous. Researchers pointed out that the elderly should avoid strenuous physical activities or sports in winter, especially in the morning. exercise , those with high blood pressure should pay more attention.
