It is very important to choose a suitable time for physical exercise, which should be chosen according to the specific external environment and your own situation. I suggest that the summer time for patients with hypertension is 8-9 am, and the best time for exercise is around 17 ~ 18 in the evening, followed by 1 ~ 2 hours after dinner. For office workers, it is suggested to exercise around 19 ~ 20: 00 in the evening: in winter: in the afternoon 15- 16, after dinner 1 hour in the evening. Patients with severe hypertension and those with serious complications should not exercise. The level of blood pressure can't depend on self-feeling, only increasing the frequency of blood pressure measurement is the most accurate way. It is best to stop exercising temporarily when blood pressure rises too fast recently.

Patients with relatively stable blood pressure should do low-intensity moderate exercise in the environment below 28 degrees Celsius, such as walking, playing Tai Ji Chuan, doing health exercises, etc. Exercise should avoid the time with the highest temperature and avoid exercising in direct sunlight. With the increase of outside temperature, the exercise time and intensity should be adjusted downward. If necessary, stop the usual exercise for a short time, and then start the exercise gradually after the outside temperature is suitable.
