Precautions for swimming
The summer of hot summer is coming. The little friends are not ready to try swimming equipment. Swimming is indeed a good way to relieve summer heat. However, some drowning accidents occur every year and many families are fragmented. Although we can not make the drowning incident happen again, we can make full preparation before entering the water and reduce the damage to the minimum when it is in danger. In the following, the body Bojun from the water before and in the water summed up the precautions and methods and techniques that should be mastered in the rescue.
Before you go into the water, you should pay attention:
1. Can't swim on an empty stomach, because swimming is one of the more physical exercises. Without strong physical strength, activities in the water are prone to danger. Of course, if you have just eaten rice, you should not go into the water because the food has not yet been digested in the stomach. Severe movement will cause gastrointestinal discomfort and cause systemic cramps.
2. You must go hand in hand while swimming. You can't go alone to prevent accidents from happening.
3. When you see signs like "No swimming", you can't swim near sluice gates, places where cages are raised, obstacles under the water, and places where you protect water, because some of these places should not go, and others Dangerous.
4. In the swimming area, the bottom of the water should be selected for slow slopes. Do not place on steep slopes, especially those who have just started swimming. It is even more unfavorable on steep slopes.
5. Before you go into the water, you must also make good preparations to move your muscles and bones, prevent the body from adapting to the water, and cramps.
Water should be noted:
1. It should be shallow to deep after launching. Let the body gradually immersed in the water, and after the waist is deep, put the upper body into the water again, lick the skin, take a few deep breaths, and gradually adapt to the water temperature, then immerse the body completely in the water. Do not take off your clothes and plunge into the water. If the body temperature and water temperature are very different, the body will be strongly stimulated and cramps and other adverse reactions will occur.
2. You can't joke scary people in the water. For example, diving into the bottom of someone's legs or accidentally splashing water and carrying out some sudden attacks at the back of others may lead to drowning or accidents.
3. When you do not understand the underwater situation, you cannot arbitrarily dive. In general, the depth of diving should not be less than 3 meters, and there must be no obstacles such as whirlpools, rocks, and aquatic plants on the bottom of the water to prevent bruising or scratching the body.
4. It is best not to exceed 2 hours at a time in the water. Because the activity in the water consumes a lot of physical strength, it takes a long time for physical strength to persist, and it is easy to cause trouble.
5. If you are swimming in the lake or the sea, it is best to go to the lake and the sea first. When the water reaches the full depth, turn to swim to the shore again. The more you swim, the shallower it will be. . Do not face the heart of the lake or swim in the sea. If you encounter wind waves or physical support, you will be in danger.
What to do if swimming is in danger?
1. Difficulties most commonly encountered during swimming are muscle cramps, which occur more often in calves. When this happens, the first thing is to keep your mind calm and stop immediately. With the backstroke posture floating on the water, and then reluctantly painfully straighten the leg (or other part) of the cramp, wait for the position of the cramp to stretch and ease, and change to another position to swim on the shore. At the same time, you can also call your companions to help you return to shore.
2. When swimming, it must be based on his own skills and physical strength to decide how far the free shore will be. In deep water, don't panic if you feel cold or tired. At this time, you can switch backstroke posture, do more shallow breathing, make your emotions stable, and then slowly go back. If you do not feel able to support it in this way, please wave your hand for help. When someone comes to the rescue, they should relax as much as possible, and they should not cling to the rescuers. It would be a mistake.
3. When swimming in the lake pond, try to avoid places with aquatic plants. If you are inadvertently trapped by aquatic plants, you can't panic. Instead, you need to lighten your swimming and slow down. First, leave the long water grass and carefully feel where the plants are wrapped around. Then it's like removing gloves or Take off the socks, take off the aquatic plants, liberate the extremities first, and then take them off. If your limbs just get tangled up in water, if you are nervous, you will be overwhelmed and swing your limbs in a random manner. That way, the plants will become more and more entangled and become more life-threatening. When he feels that he is stuck in water and cannot get out of danger, he must ask for help.
How to save the risk on the water?
1. It is complicated to save people in the water. This requires not only swimming, but also specific and specific technologies. Those who have not received special life-saving training are, in general, unable to save water. Because people panic after panic, regardless of seeing people and things are clinging tightly. If the saver is held by the drowning person, the saver will not only save the person, but will not even escape from himself.
2. Of course, seeing how your partner is drowning, how can it be saved? What we did not say in the past means that we cannot rush into the water, and we cannot rely on the drowning person to go forward. Instead, we should think of other ways to help. First of all, hurry to shout people, but also think of aid on the shore. For example: throwing a lifebuoy, foam, rope, etc. to the drowning person, and conditional ones can also throw him some planks, logs, etc. If shore aid is ineffective, people with good swimming skills can also come to the rescue, but they must bring rescue items such as ropes, clothing, and towels (preferably tie them together), and they should be a couple of meters away from the drowning person. , throw the salvage items to him. Let him pull the end of the salvage item, and the rescuer pulls the other end and pulls the drowning person to the shore. If there is no salvage item, the situation is particularly urgent. A person with good water quality can approach him from the back or side of the drowning person, and then, without letting the drowning person catch it, use a backstroke or side-swimming posture to pull the drowning person. Come to the shore.
3. The drowning person may die 6-8 minutes after drowning. Therefore, to save people, they must also be rescued in a timely manner. First of all, we must look at the salvaged person's mouth, no dirt in the nostrils, water grass and other types of dirty things, and if so, clean up as soon as possible. Then, put his head in the lower position and put the body higher, allowing him to control the inhaled body of dirty water. At this time, if the drowning person has suffocated, he must take artificial respiration while sending him to the hospital for emergency treatment. Also pay attention to warming the drowning person to maintain body temperature and continue the vitality of the heart.
