How to write drowning prevention?

1, don't swim alone, let alone in places where you don't know the bottom and water conditions, or in places that are dangerous and prone to drowning casualties.

Pupils should not swim in too cold water. If they feel that there is a big difference between the water temperature and the body temperature, they should get into the water slowly and get used to it gradually, and try to reduce the frequency and the stimulation of cold water to the body.

Pay attention to your health. People who are prone to limb cramps should not take part in swimming or swim in deep water. Get ready before you go into the water and exercise first. If the water temperature is too low, wash your body with shallow water first, and then go swimming after getting used to the water temperature. Students who wear dentures should take off their dentures to prevent them from falling into the esophagus or trachea when they suffocate.

4. Swimming should be carried out in the swimming area with safety protection zone, and swimming in the non-swimming area is strictly prohibited. Children in rural areas should choose areas that are familiar with underwater conditions.

It is very dangerous to encounter heavy rain when swimming outdoors, so you should go ashore immediately and go to a safe place to avoid the wind and rain.
