When you are tired of swimming and plan to rest, you should keep warm, especially your head. The human head is the easiest to dissipate heat. If the hair is wet after using water and showering, it will easily lead to rapid heat loss. Therefore, put on a bath towel after taking a break, dry your hair in time after taking a shower, get dressed, and if possible, it is best to dry your hair with a hair dryer. Step 2 be fully equipped

The requirements of swimming pools for swimsuits, goggles and caps are indispensable. It is suggested that you must bring slippers when swimming to avoid catching cold on your feet, and bring a bath towel or towel coat to keep warm after rest or bathing. In addition, the room temperature in the swimming pool is high and the humidity is high. It is recommended to wear clothes that are relatively simple, easy to put on and take off, and have good warmth, so as to change clothes. Body cleaning products and cleansing cream, skin cream and shampoo are also essential items. 3. Adequate preparation activities

Warming up before swimming is the key. You must move your joints before you go into the water. It is suggested that you can do more stretching exercises such as jumping up and down, pulling your shoulders and vibrating your arms by the pool, and focus on warming up your legs, arms and waist to prevent cramps during swimming.

Generally speaking, the preparation time is about 5- 10 minutes, and it feels a little red, just a little hot.
