From the perspective of TCM health, it is better to run in the morning or at night.
As far as TCM health care is concerned, morning is a good exercise. In the morning, the air is fresh and the amount of oxygen is relatively large. Especially in spring, summer and autumn, everything starts a new day and is full of vitality, so many people do morning exercises. However, morning exercise or evening exercise also varies from person to person, depending on your own living habits and hobbies. Whenever you exercise, it is good for your health. You can exercise once or twice a day for about an hour each time.
