Common warm-up exercises for children, such as running, jumping or deep breathing, are enough. You need to rub your face, palms and ears more in winter. Most parents understand the importance of warming up their children, and few people care too much about how to "cool down".

"Cold body movement" is a relaxation process that transforms the body from a moving state to a static state. If the child suddenly stops to rest after exercise without going through a relaxation process, and the blood pressure drops too fast, the heart will be short of blood supply, which is prone to dizziness, nausea and other hypoxia symptoms. Jogging and brisk walking are the simplest and most practical cold body exercises.
