1. First of all, pay attention to cold and warmth, that is, wear thick enough clothes, gloves, earmuffs, hats, etc. before exercise. Avoid frostbite or headache, frostbite and other symptoms when necessary. After exercise, you should wipe your sweat and take a bath in time to prevent colds.

2. Warm-up exercises must be done before exercise to ensure the activity of joints and muscles, thus reducing the chances of injuries to muscles, ligaments and joints.

3. Because the winter climate is relatively dry, it is necessary to fully replenish water before and after running in winter, drink some warm water properly, or use fruit juice or porridge to prevent water shortage in the body due to dry climate.

In addition to the above points, we should also consider choosing the time for exercise in winter, because it is too cold in the morning to exercise. Try to exercise in the afternoon, and don't overdo it. Adjust the exercise time reasonably as far as possible, keep a good breathing rhythm during exercise and improve the exercise effect.
