This may be related to habits. Generally speaking, after exercise, especially after strenuous exercise, the body will lack the use of oxygen and blood. If you go to bed right away, your body won't recover soon. Moreover, the hormone level of the body will rise quite high after squatting, which is why the muscles will expand during exercise and the explosive energy state will be quite strong. It is generally recommended to supplement a small amount of fruits, such as bananas, after exercise and rest for half an hour before going to bed. After a long time to form a habit, there will be no such problem!
