How to call for help when people fall into the water?
Students, summer is coming. The hot weather is coming, and people may go swimming to reduce their fever. Yes, it's a good idea, but maybe when we inadvertently, the danger is around us. Children's drowning often happens. 3. 14 In the afternoon, several students from Minhou Experimental Middle School in Fujian went swimming in Minjiang River, and one of them drowned. That night, the parents didn't see the child, so they went back and looked around, but they couldn't find it. I heard that a schoolbag was found on the Minjiang River the next day, and then the child's body was salvaged in the water: at 20 o'clock on the 5th, a child drowned in Aksu City, Xinjiang; two children were playing beside a puddle in the waters next to the Hongqi Brick Factory in this city; a 7-year-old child unfortunately fell into the puddle and drowned; on the morning of April 6th,1kloc-0/,a child died in Baoting County, Hainan Province. In the afternoon 14, a worker in No.3 Sandyard of Nandujiang, Ding 'an County drowned due to careless operation ... The drowning incident of these children is in front of our eyes, and I can't help thinking: Why are so many people drowning? How can we prevent this incident from happening again? The following is my advice to you: 1 When swimming in the swimming pool, be sure to have an adult who can swim beside you. 2. Don't swim in canyons and reservoirs 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; 3. Don't go into the water, especially in the wild; Don't swim when the wind and waves are too strong and the lighting is not good; Don't be too hungry and full when you go into the water. Don't go into the water for an hour after meals to avoid cramps; You can't swim when you have a cold, illness, physical discomfort or weakness. 6. Be fully prepared, such as warm-up preparation to prevent cramps. 7. Try the water temperature before entering the water. If the water is too cold, rub some water on your limbs before swimming, and then jump into the water. Don't jump into the water at once; 8. When you have abdominal pain, you should go ashore. It is best to drink some hot drinks or soup to keep warm. The above is what we should pay attention to when swimming. What if you really drown? 1, don't panic, don't mess around in the water. In case of cramps, please keep calm; 2. When drowning happens, if you are unfamiliar with the water, you can take self-help methods: 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 specific gravity of human body drops, which is slightly lighter than water and can surface. At this time, don't panic, don't raise your arms and let your body sink faster; 3. If the hands and feet cramp, if the fingers cramp, you can make a fist with your hand, then open it hard and do it several times quickly until the cramp is eliminated; If the calf or toe cramps, first take a deep breath and float on the water, hold the toe of the cramped limb with the hand opposite to the cramped limb and pull it toward the body. At the same time, press the palm of the same side on the knee of the cramped limb to help the cramped leg straighten. If the thigh cramps, it can also be solved by lengthening the cramped muscles. Students, who doesn't want to have a cool holiday in a beautiful summer? However, if you are not careful, danger may occur. So we should cherish life and create a wonderful time for ourselves.
