When is the morning exercise ready?

Many elderly people like to do morning exercises, or walk, or practice swords, or walk the birds, or play Tai Chi, and their leisure goes without saying. However, morning exercise is also particular, so we should choose the best time in the morning to exercise, so as to achieve the best exercise purpose.

Exercise in the morning can activate the muscles and joints that have been stagnant for one night, increase the number of slow heartbeats for one night, and enhance the ability of heart contraction. The ancients said: Yinshi (3 ~ 5 o'clock) exercise can improve the effect and health, so the traditional morning exercise usually starts at 4 ~ 5 o'clock. At 5 o'clock in summer and early autumn, it is dawn, the sun rises gradually, and the air is fresher than at night. It is really a good time to exercise. However, it is not scientific enough for the elderly and the infirm to take part in exercise before dawn at 5 o'clock in winter and early spring.

specifically, the morning exercise time of the elderly should be selected according to the celestial body movement law and the physiological rhythm of the human body, with the passage of time, the overlapping of seasons, the change of climate and the difference of regions. For example, in the vicinity of Beijing, Wuhan and Guangzhou, the best time for morning exercise is from 5: to 7: in May to August, from 5: 3 to 7: 3 in March to April and from September to October, from 6: 3 to 8: 3 in January to February and from November to December.

The general principle of timing morning exercises is that it is better to start at dawn to 1-2 hours in all seasons. Scholars point out that exercise at this time has the following advantages.

① After dawn, the temperature rises gradually, and the cells, tissues, blood vessels and meridians of the human body can relax with it, so that the qi and blood are smooth and can adapt to various activities.

② After dawn, trees and flowers change from absorbing oxygen at night to releasing oxygen, which increases the oxygen content in the air. In particular, due to the effects of solar radiation, the air is ionized, producing more negative ions, and exercising in this environment has many benefits.

③ After daybreak, sunshine can promote human metabolism and improve people's mood, so exercise at this time is a win-win situation!
