Swimming must avoid these six points. In hot summer, many people have accidents because of swimming, so pay attention to safety when swimming. Here I have compiled some information about swimming that must avoid these six points. Let's have a look!
Swimming must avoid these six points 1.
Precautions for swimming
First, avoid swimming on an empty stomach and after meals.
If you swim in the water when you are hungry on an empty stomach, you can't supply enough energy to your body because your blood sugar is low. In addition, your body consumes a lot of energy and can't replenish it in time, which is easy to cause hypoglycemia, dizziness, palpitation, fatigue and other symptoms, and even collapse, leading to unexpected dangers such as drowning. Swimming after a full meal not only affects the digestion and absorption of food in the gastrointestinal tract, but also easily causes stomach cramps, vomiting, abdominal pain and other phenomena. So don't swim on an empty stomach, rest for 30 minutes to an hour after meals, and then swim in the water.
Second, avoid swimming after drinking.
If you drink, don't go swimming, it's very dangerous! Because drinking will consume a lot of glucose stored in the human body, alcohol will also inhibit the normal physiological function of the liver and hinder the transformation and storage of glucose in the body, which is prone to hypoglycemia. In particular, alcohol will interfere with the rhythm of excitement and inhibition in the cerebral cortex, and the brain will be dizzy, which will affect the ability to judge the situation in water. These factors will undoubtedly increase the chances of swimming accidents and should be taken as a warning.
Third, avoid swimming after labor or strenuous exercise.
After work or strenuous exercise, some people often sweat and jump into ponds or rivers to swim in order to have a good time. As we all know, during labor or strenuous exercise, the body produces more heat, the body temperature rises, and the skin sweat glands and subcutaneous blood vessels dilate. If you suddenly jump into the cold river, the hot body will be stimulated by cold, and the subcutaneous blood vessels will shrink sharply and the sweat pores will be blocked, which will easily lead to diseases such as colds and acute joint pain, and even lead to limb paralysis in severe cases. So, rest for half an hour, and then go swimming when the sweat drops.
Fourth, avoid swimming during menstruation.
During menstruation, women's physical resistance decreases. If they go swimming and are stimulated by cold water, it is easy to cause amenorrhea and dysmenorrhea. Bacteria can also cause urinary and reproductive system infections.
5. People with certain diseases should avoid swimming.
Patients with severe coronary heart disease, hypertension that is difficult to control with drugs, rheumatic valvular heart disease, congenital heart disease, severe arrhythmia, epilepsy, acute conjunctivitis, open trauma and various infectious diseases are not allowed to swim.

Five, how to prevent drowning
Swimming is one of teenagers' favorite sports. However, if you are not prepared, lack safety awareness, panic when you encounter an accident, and you can't save yourself calmly, it is easy to cause drowning casualties.
In order to ensure the safety of swimming and prevent drowning accidents, the following must be done.
1, don't go swimming alone, let alone in places where you don't know the bottom and water conditions, or dangerous places where drowning casualties are likely to occur. Choose a good swimming place and have a clear understanding of the environment of the place, such as whether the reservoir and bathing place are sanitary, whether the water surface is flat, whether there are reefs, undercurrents, weeds and the depth of water.
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, it is necessary to count the number of people before and after launching and designate lifeguards 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. If the water temperature is too low, wash your body with shallow water first, and then go swimming after getting used to the water temperature. Students with dentures should take them off to prevent them from falling into the esophagus or trachea when choking.
4. Be self-aware of your own water quality, don't be brave after entering the water, don't dive and snorkel rashly, and don't fight with each other to avoid drowning. Don't swim in rapids and whirlpools, let alone drink and swim.
5. If you suddenly feel unwell during swimming, such as dizziness, nausea, palpitation, shortness of breath and so on. , should immediately go ashore to rest or call for help.
6, in swimming, if the calf or leg cramps, don't panic, you can kick or jump hard, or massage hard, strain the cramp, and call for help to your partner.
7. When a drowning accident occurs in swimming, the first aid on the spot is urgent, and cardiopulmonary resuscitation is the most important. After the drowning person is rescued ashore, the vomit, sediment and other impurities in the oral cavity and nasopharyngeal cavity should be removed immediately to keep breathing smooth; The tongue should be pulled out to avoid backward turning and blocking the respiratory tract; Raise the belly of the drowning person so that his chest and head droop, or hold his legs, put his belly on the rescuer's shoulder, and do the action of "pouring water" by walking or jumping. 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.
