8-9 pm is the best exercise time. Generally speaking, it is recommended that the running time should not exceed 1 hour, leaving enough time for bathing and rest to avoid getting too excited before going to bed, resulting in poor sleep quality. Huangdi Neijing pointed out that you can go to bed late and get up early in summer, so considering the temperature, low-intensity fun running is also recommended as an exercise method in the coming summer.

Data expansion: 1, the benefits of fun running: a good way to lose weight.

For all people who have no time to exercise during the day, fun running has become the best choice. Contrary to morning running, the number of platelets in fun running decreased by 20%, which greatly reduced the risk of vascular embolism.

After fun running, the brain secretes more melatonin and growth hormone during sleep, which can promote the growth and development of teenagers, improve the immunity of adults and promote sleep.

At night and at night, hormones, the key substances of human metabolism, have the strongest response to physical exercise. This also means that fun running is a good way to lose weight.

2. Disadvantages of fun running: it is easy to get sick when blowing.

In addition to experiencing the late peak, there is also the problem of air quality. In the view of Chinese medicine, sweating is vulnerable to wind and evil, and excessive exercise at night consumes yang, which is not conducive to human health.

Huangdi Neijing records that "quietness is the principle of physical rejection, although there is strong wind, it can be harmful", which means that people's skin is closed in a calm state, and even if strong wind blows, it can't hurt the body.

However, when people are running, blood flows to the limbs one after another, which makes the temperature rise and the acupoints open after being heated. Blowing at this time, exogenous cold and evil can easily get in and bury hidden dangers of the disease.
