For people with high blood pressure, the best time to exercise is 1-2 hours after dinner. Comparatively speaking, the two highest blood pressure periods in a day for hypertensive patients are 6-10 am and 4-8 pm, so this is precisely one of the reasons why patients have a higher probability of having cerebrovascular accidents in the early morning. Therefore, it is not recommended for hypertensive people to do outdoor exercise, such as running or swimming, in the early morning, which may cause cardiovascular and cerebrovascular accidents. Exercise 1-2 hours after dinner, this time is relatively safe, and the blood pressure at this time tends to be more stable. It is recommended that patients do not exercise for too long each time, preferably more than 30 minutes, but not more than 45 minutes, each time do not do too strenuous exercise, to the forehead and the back of the slight sweat is the most appropriate.
