You must be organized and swim under the guidance of a teacher or someone familiar with water. Take care of each other. If a collective organization goes swimming, the number of people should be counted before and after launching, and lifeguards should be designated for safety protection;
Pay attention to your health. People who are prone to cramps in limbs should not take part in swimming or swim in deep water. Get ready before you go into the water and exercise first.

Restoring the drowning person's breathing is the key to the success of first aid. Artificial respiration should be carried out immediately, and mouth-to-mouth or mouth-to-mouth artificial respiration can be used. At the same time of first aid, you should be sent to the hospital for treatment quickly.

As school parents, how to prevent teenagers from drowning has become particularly important. It is necessary to know some common sense to prevent drowning.
First, swimming safety points: 1. Don't be too hungry and full when you go into the water. Don't go into the water for an hour after a meal to avoid limb cramps; 2.

Observe the swimming environment before launching. You can't swim here if there is a danger warning. Don't swim in the canyon with unclear geographical environment. The water in these places is different in depth and cold, and obstacles may hurt people in the water, which is very unsafe; 6. Before diving, make sure that the water depth here is at least 3 meters, and there are no weeds, rocks or other obstacles underwater. It is safer to enter the water with your feet first; 7. When swimming in the sea, you should be parallel to the coastline. Those who are not skilled in swimming or lack of physical strength should not go deep.

If the calf or toe cramps, first take a breath and float on the water, hold the toe of the cramped limb with the hand on the opposite side of the cramped limb, pull it toward the body, and press the palm of the same side on the knee of the cramped limb to help the cramped leg straighten; 3. If the thigh cramps, it can also be solved by lengthening the cramped muscles. First aid for drowning: The first aid methods after drowning are: 1. After lifting the wounded out of the water, immediately remove the water, mud and dirt in his mouth and nasal cavity, wrap his fingers with gauze (handkerchief), pull his tongue out of his mouth, unbutton his clothes and neckline, and keep the respiratory tract unobstructed. Then, pick up the waist and abdomen of the wounded, make him look up to pour water, or pick up his legs. 2. People who stop breathing should immediately carry out artificial respiration, and mouth-to-mouth blowing is generally the best. First-aiders are located on the injured side, hold the injured person's jaw, hold the injured person's nostrils, take a deep breath, slowly blow into the injured person's mouth, relax the nostrils when the chest is slightly lifted, and press the chest with one hand to help him exhale, repeatedly and rhythmically (blowing 16~20 times per minute). 3. If the heartbeat stops, you should do the chest first.

What should I do if my ears get water while swimming? The most commonly used method is: 1.

Active external auditory canal method: you can press the tragus continuously with your palm or pull the auricle with your fingers; Or repeatedly open your mouth and move the temporomandibular joint, which can make the skin of the external auditory canal move up and down, left and right, or change the stability of the water barrier and pressure, so that water can flow out of the external auditory canal; 3. External auditory canal cleaning method: gently probe into the external auditory canal with a clean cotton swab, and suck out the water once it hits the water barrier.
Because the swimming pool or river water is unclean, the skin and tympanic membrane of the external auditory canal are infected after sewage enters the ear, or the water is improperly treated after entering the ear, which can often cause the following ear diseases, such as unclean ear digging. : otitis externa, swelling of external auditory canal, otitis media and suppurative otitis media.

8. knowledge of preventing drowning
There are many online. I've been looking for work materials for the past two days.
Summarized a little common sense and shared it.
First, the cause of drowning death
It is mainly due to the inhalation of a large amount of water in the trachea that hinders breathing, or because of the strong spasm of the larynx and the closure of the respiratory tract.
Second, symptoms
The drowning person's face is bruised, his eyes are bloodshot, and his mouth, nostrils and trachea are full of blood bubbles. Cold limbs, weak pulse, even convulsions or respiratory heartbeat stop.
Third, self-help and rescue.
When drowning happens, if you are unfamiliar with the water, you can take the method of self-help: in addition to calling for help, take a supine position and tilt your head back so that your nose can breathe out of the water. Shallow exhalation and deep inhalation. Because when inhaling deeply, the body specific gravity drops to 0.967, which is slightly lighter than water, and can surface (when exhaling, the body specific gravity is 1.057, which is slightly heavier than water), so don't panic at this time, and don't raise your arm and flap it left and right to make your body sink faster.
Swimmers, if they have cramps in their calves, should keep calm, take a backstroke posture, bend the toes of the cramped legs backwards with their hands to release the cramps, and then slowly swim to the shore.
To rescue the drowning man, swim to the vicinity of the drowning man quickly, observe the position clearly and rescue him from the rear. Or throw boards, lifebuoys, long poles, etc. So that the drowning person can climb ashore.
After the water rescue:
First clean up the silt and sputum in the mouth and nose of the drowning person, take off the false teeth, and then control the water. The rescuer kneels on one leg, puts the drowning person on the rescuer's thigh, and uses * * * to discharge the water in the drowning person from the trachea and mouth. In some rural areas, the drowning person will lie on the back of the cow, with his head and feet suspended, driving the cow to walk, thus controlling water and playing the role of artificial respiration. If the drowning person's breathing and heartbeat have stopped, give mouth-to-mouth artificial respiration immediately, and at the same time, give the heart outside the chest.
