Why does it hurt to play basketball in winter?

Playing ball in winter, due to the cold weather, leads to cold body, stiff body and incomplete muscle relaxation, so the blood in the blood vessels flows slowly and hurts when exercising vigorously. Suggestion: do warm-up exercises first, such as jogging for a few laps, and try to make your body hot and sweaty. When your body is hot, the blood in your blood vessels will speed up circulation, and then you won't feel pain when you do strenuous exercise. Try to make your hands hot and your palms sweat.
