What should you pay attention to before swimming?

Swimming is a fitness exercise that many people like, especially in summer, because of the climate, more people swim. However, many people also die from swimming because they have no knowledge of swimming and therefore are not fully prepared when swimming. Do you know what are the taboos and emergency measures when swimming? Next, let’s take a look at what to prepare before swimming and what to pay attention to.

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.

Leg cramps are one of the more common phenomena when swimming. Once they occur, it is not only extremely painful but also makes it impossible to move. Drowning accidents may occur if rescue is not provided in time. When your leg cramps, do not panic, stay calm, try to rescue people around you, and massage the cramped area more after getting ashore.
