Speaking of games, it is actually a kind of fitness exercise that many people like, especially in the hot summer. Because of the weather, many people like to go swimming. But everyone also knows that in life many people do not understand the things they need to pay attention to, and often many people die from swimming. Because of this, it is even more necessary for everyone to understand what to pay attention to before swimming to avoid problems. Pay attention to eight taboos when swimming: First, avoid swimming before or after meals. The blood sugar level in the body is low when the stomach is empty. Swimming can cause dizziness, weakness in the limbs, and even accidents. The activity of the digestive organs is enhanced after meals, and swimming causes a large amount of blood to flow to the limbs, which reduces the amount of blood in the digestive tract and affects the digestion and absorption of food. Second, avoid not doing warm-up exercises. In summer, the water temperature is much lower than the air temperature, so swimmers should do warm-up exercises before entering the water. If you are not physically prepared and cannot adapt to the water environment for a while, it is easy to cause discomfort symptoms such as dizziness and nausea. In severe cases, you may suffer from cramps or muscle strains. Third, avoid swimming when you are sweating profusely. Your blood vessels dilate when you sweat, and when stimulated by cold water, the blood vessels suddenly contract, which can easily cause illness. Fourth, avoid swimming after strenuous exercise. Strenuous exercise makes the body tired, and muscle contraction and reaction ability are weakened. Swimming will increase the burden on the cardiopulmonary system, making accidents such as swallowing water, cramps and drowning more likely to occur. Fifth, avoid swimming for too long. Generally, the appropriate time to stay in water is 30-60 minutes. 6. Avoid swimming when you are not feeling well. People who suffer from cardiovascular and cerebrovascular diseases, infectious diseases, traumatic inflammation, and women during menstruation should not swim. Seventh taboo: ignore hygiene after swimming. After swimming, you should rinse your body with clean water, dig out the water in the ears, and use eye drops to disinfect the eyes. Eight, avoid swimming in unfamiliar waters. When swimming in natural waters such as rivers and reservoirs, you should understand the water depth, the natural conditions at the bottom of the water, and the conditions of flora and fauna in advance. Do not enter the water rashly to avoid accidents. In life, many people do not take proper precautions before swimming, which often leads to dangerous situations due to leg cramps while swimming. If there is a professional swimming teacher at this time, the danger can be avoided. However, if there is no professional teacher, if cramps occur, don't be too anxious, stay calm and don't move. It is better to wait for help from others. |
