2. Do full-body exercise before swimming, fully exercise joints and relax muscles to avoid cramps, sprains and other accidents after entering the water. If you have a cramp, be calm, don't panic, and help yourself while shouting. Common is calf cramp. At this time, you should do backstroke, hold your toes with your hands, push your calves forward hard, and try to get close to shallow water or shore. ?
Don't dive from a height, lest you hit something hard. You can play water polo in the water, but you can't make fun of, play tricks on, push down your partner, pull your partner deeply or dive into your partner. ?
4. Swimming should be carried out in the swimming area with safety protection zone, and swimming in the non-swimming area is strictly prohibited. Swimmers should choose areas that are familiar with underwater conditions.

Self-rescue by drowning: The drowning person should not panic, but should keep calm and actively save himself. Breathing in through the nose when swimming is the most likely cause of suffocation. If you choke on water, first open your mouth and take a deep breath. Even after a few sips of water, you must open your mouth instead of inhaling through your nose. ?
1, water cramp self-help method?
The main parts of cramps are calves and thighs, and sometimes fingers, toes and stomach cramps. ?
(1) If you get cramps while swimming, don't panic. Be sure to stay calm, stop swimming, take a deep breath first, float on your back, and take different self-help measures according to different parts. ?
(2) After pumping the tendons, swim back to the shore in another swimming posture. If you have to still use the same swimming posture, you should be wary of cramping again.
2. Water grass self-help method
(1) First of all, calm down, never step on water or tamper with your hands, otherwise it will make it harder for your limbs to get entangled or sink deeper and deeper in the mud. Use backstroke (legs straight, palms back) to slowly back along the original path. Or lie flat on the water, let your legs separate and let go with your hands. ?
(2) If you carry a knife with you, you can cut the grass, or try to kick it away, or smooth it off your hands and feet like taking off your socks. When you can't get rid of yourself, call for help in time. After removing the aquatic plants, kick and swim lightly and leave the place where the aquatic plants are overgrown as soon as possible.
3, fatigue excessive self-help method?
(1) If you feel cold or tired, you should swim back to the shore immediately. If you are far away from the shore, or too tired to return to the shore at once, float on the water to save your strength. ?
(2) Raise your hand, relax and let the other person save. Don't cling to the rescuer. If no one comes, continue to float on the water and swim back to the shore when your physical strength is restored.
4, trapped vortex self-help method?
(1) Where there is a whirlpool, there are often rubbish and leaves swirling around the whirlpool on the water surface. As long as you pay attention, you can find it early, and you should try to avoid getting close. ?
(2) If you are close, don't tread water. You should lie flat on the water immediately, swim quickly and crawl along the edge of the whirlpool. Because of the weak attraction of the vortex edge, it is not easy to get involved in large objects, so the body must lie flat on the water, and must not step on the water or dive vertically into the water.
