Enter the swimming pool
Before entering the swimming pool, you need to go to the shallow water area and feel the water temperature with your toes to avoid sudden entry into the water and causing physical discomfort. If the water temperature is suitable, you can slowly enter the water, first immerse your body in the water, and then practice swimming postures such as breaststroke and freestyle.
