Generally speaking, the best time for outdoor sports should consider two factors: human health and air quality.

In general, air pollution has two peaks every day, before sunrise and in the evening. Because everyone lives and works in different ambient air quality, we should pay attention to the change of air pollution index when exercising outdoors.

Research shows that the state of human ability changes day and night.

Every morning at 7: 00- 12: 00, 14: 00- 18: 00, the muscle speed, endurance and explosiveness are in a relatively optimal state. If you exercise during this time, the effect will be better. 3: 00-6: 00, 12:00- 14:00 are all in a relatively depressed state. If you exercise during this time, the "load" is too large, and the probability of sports injury may be greater.
