What are the precautions of swimming?
In order to ensure the safety of swimming, people should master the following self-care knowledge and skills:
1. Swimming utensils, such as swimsuits and water mirrors, should be cleaned and disinfected frequently. After each swim, it is advisable to wash eyes with clean water, and then drop a few drops of eye drops. For hydrops in the ear, the head side can be tilted and the water can flow out by jumping with one leg in place.
2. Do not swim without the teacher's permission.
3. Make preparations before launching to avoid discomfort. Only when the lifeguard is present can you launch.
4. Don't go swimming if you are sick.
5. Avoid swimming before and after meals. Swimming on an empty stomach will affect appetite and digestive function. It will also cause dizziness and fatigue during swimming. Swimming on a full stomach will also affect digestive function. It will also produce stomach spasm, even vomiting and abdominal pain.
6. Beginners should not swim in deep water for safety.
7. Do not run in the pool area.
8. Obey the teacher's management, no diving, no dangerous actions and games.
9. Swimming too long can cause muscle fatigue. Sudden cold or sudden force can cause cramps in the water. In this case, calm down, relax, massage the muscles of the cramped area, or change the swimming posture, and go ashore to have a rest.
10. After taking part in strong physical labor or strenuous exercise, you can't jump into the water to swim immediately, especially when you are sweating and hot all over. Otherwise, it is easy to cause cramps, cold, etc.
11. Don't dive on the shallow side of the pool.
12. Don't take the water bottle and glassware to the swimming pool to avoid breaking them.
13. Leave the swimming pool for shelter in case of lightning shower.
14. Long time exposure can cause sunburn or acute dermatitis, also known as sunburn. In order to prevent the occurrence of sunburn, after landing, it is best to use an umbrella to protect the sun, or go to a shady place to rest, or use a bath towel to protect the skin, or apply sunscreen on the exposed part of the body.
15. If someone is flooded and you can't swim, don't go into the water. You can shout for help, or throw down rescue creatures, such as sticks, boards, etc.
16. Never play in the water, just in case something happens.
17. Don't wear a snorkel. Once you choke, it's very dangerous.
18. If you find a swimming accident, call for help immediately and take action. Make an emergency call quickly or take a car to the hospital.
19. During the swimming activities, no one is allowed to leave the swimming pool area without the teacher's permission; after the swimming activities, each class must check and verify the number of people before leading the team to leave.
20. After swimming, wipe off the scale on the body with a soft dry towel, drop chloramphenicol or boric acid eye drops, and blow out the nasal secretions. If there is water in the ear, the water can be discharged by "ipsilateral jump". After that, do some relaxation exercises and body massage or take a rest in the sun for 15-20 minutes to avoid muscle stiffness and fatigue.
21. It's better to take a rest before eating after swimming, otherwise it will suddenly increase the burden of gastrointestinal tract and easily cause gastrointestinal diseases for a long time.
Before swimming for the first time, you should have a health check-up. People with viral hepatitis, active tuberculosis, red eye disease, otitis media, diarrhea, heart disease, psychosis and epilepsy are not suitable for swimming.

You should also wash your face, head, chest, back and four livers with water before swimming.
When swimming, painful convulsions (commonly known as cramps) are often encountered. When cramps occur, keep calm and swim ashore as soon as possible. Wait for your body to return to normal before you enter the water. Methods to correct cramps: fingers cramps can be clenched into fists, and then force to open the hands; toes cramps, we should quickly bend the leg, force to pull the toes open, straighten; calf cramps can first take a breath, float on the water, bend the thigh to make a right angle with the upper body, and the knee joint is also bent up, force to make the calf stick to the thigh, back and forth vibration a few times, then After the leg straight forward, repeated activities, until return to normal. If the cramps are serious or continue to occur, do not continue to swim.
