Precautions for swimming in summer

Warm up the body before you go into the water, which can avoid cramping due to not adapting to the water temperature.
Avoid fasting when swimming. If you go swimming on an empty stomach, the heat energy stored in the body will be consumed quickly. If the body does not get enough energy supply, the blood glucose content will become very low. It is easy to lose strength, dizziness, coma or even drown in the process of swimming.

Therefore, the swimming place should be in familiar waters or natatorium as far as possible.
