Do you have any suggestions for swimming in low water temperature?

My friend, swimming is really a good exercise, and the water temperature has a great influence on the human body. Generally speaking, the water temperature of a standard swimming pool is 26.5 degrees, below which the water temperature is low. If you swim in a swimming pool below 26.5 degrees, or in rivers, lakes and seas, or even in winter. The following points should be noted:

1, under the condition of ensuring good health, we must make full preparations and exercise our whole body to prevent cramps in the water.

2. Before entering the water, touch the water temperature with your hands, and then splash water on yourself to make your body adapt. If you think it's acceptable, go into the water. If you can't accept it, don't go into the water.

3. The launch time should be controlled well, not too long. If you are swimming with children, even the standard water temperature can't last long. When we teach children to swim, we usually adjust the water temperature to 28 ~ 30 degrees, which is easy for children to accept.

4. After swimming in low water temperature, you must do a good job of tidying up. Hot water bathing is the best. If you don't have a good brush, keep warm in time and drink some hot water.
