Why do swimmers drown? Self-help methods for swimming and drowning

1 Physical reasons Drowning accidents caused by physical reasons mostly happen to swimmers with weak constitution or hidden diseases. Because swimming time is too long, water temperature is too low, exercise is too intense and physical exertion is too large, it will cause dizziness, fainting or the onset of hidden diseases, which will lead to swimmers fainting in the water and lead to drowning accidents.

Precautions: Before swimming in the water, swimmers should have a comprehensive physical examination. According to your physical condition, the temperature and water temperature at that time, master the swimming time appropriately. Swimming should be gentle and moderate, avoiding strenuous sprints and long-term diving.

2 Technical reasons Due to technical reasons, drowning accidents are more common among novices. Generally, beginners can't master the correct swimming skills, especially the skills of breathing, floating and treading in water, so they often choke and drink water in swimming, coupled with unexpected reasons such as fatigue, which destroys the correct sports skills and causes the body to sink and drown.

Precautionary measures: Swimmers should first be familiar with water-based exercises, master the correct breathing method and the method of floating on the water, and then skillfully learn and master the breaststroke and treading techniques, so as to quickly get the time to enter and stay in the water.

3 Psychological reasons Due to psychological reasons, drowning accidents are more common, especially for novices. Some beginners are too nervous when swimming, worried about their own safety, and have a heavy psychological burden, which leads to the protective inhibition of the swimmer's cerebral cortex, which makes the movements stiff, reduces the coordination, destroys the correct sports skills, and leads to choking, drinking and sinking, thus causing drowning accidents.

Preventive measures: strengthen protective measures to relieve the psychological pressure of swimmers, invite swimmers to accompany them, and take rescue measures in time if there is danger.

4 Accident factors Swimming is an accident that causes swimmers to drown. There are many accidents.
