What should you pay attention to when swimming?

For those who want to lose weight, swimming is a good form of exercise. It is only good for people who can swim, but people who cannot swim generally do not pay enough attention to some precautions. There will be many problems, and if it is serious, it will be life-threatening to the human body, so I hope everyone can understand what to pay attention to when swimming?

When swimming at the beach, pay attention to the tide time. After high tide, the tide will ebb. Please try not to swim at low tide to avoid excessive physical exertion when swimming back at low tide and causing accidents.

Do not swim in non-swimming areas. The water conditions in non-swimming areas are complicated, and there are often reefs, aquatic plants, silt and whirlpools. Accidents may occur if you are not careful. Therefore, before going into the water, you must conduct a thorough investigation and research in the local area to know what is going on and stay away from aquatic plants, reefs, whirlpools and silt as much as possible.

Do not drink alcohol before swimming. Swimming after drinking alcohol will cause a large amount of glucose stored in the body to be consumed, resulting in hypoglycemia. In addition, alcohol can inhibit the normal physiological functions of the liver, hinder the conversion and storage of glucose in the body, and thus cause accidents. At the same time, alcohol can affect the brain's judgment ability, increasing the chance of swimming accidents.

After going ashore, you should avoid exposure to the sun and pay attention to protecting your skin. In order to avoid strong sunlight, it is best to apply sunscreen. Before bathing in the sea, you need to prepare on the shore, then soak your skin in shallow water to make your body suitable for the water temperature. Please do not climb the reefs when bathing in the sea to avoid being scratched by oysters.

Benefits of swimming

Exercising in water reduces the impact of the ground on bones during ground exercise, lowers the chance of bone aging and makes bone joints less likely to deform. The resistance of water can increase the intensity of human exercise, but this intensity is different from equipment training on land. It is very gentle, and the intensity of training can be easily controlled within the aerobic range. It will not grow very stiff muscles, and can make the lines of the whole body smooth and beautiful.

5. Strengthen lung function

Swimming helps develop respiratory muscles, increase chest circumference, and lung capacity. It also opens more alveoli during inhalation, making ventilation smoother.

6. Skin care

When swimming, the water washes the skin, sweat glands and sebaceous glands, which has a good massage effect, promotes blood circulation and makes the skin smooth and elastic.

Those who want to swim hope to read these precautions carefully, so that there will be no problems when actually swimming. I also hope that everyone knows that it is not recommended to swim on an empty stomach or without eating. Doing so can cause great harm to the human body and stomach. At the same time, novices must swim under the guidance of a professional teacher to avoid problems.
