The benefits and precautions of swimming

Swimming is a very good sport, but it is not suitable for people who are not good at swimming, otherwise it is easy to get into danger. However, even if you are not a good swimmer, there is generally no danger in swimming in a swimming pool. Just don't go swimming in the wild. Many people regard swimming as a daily fitness exercise, and even go swimming in winter. So, what are the benefits and precautions of swimming?

Benefits of swimming

1. Enhance myocardial function

2. Enhance immunity

People who regularly participate in winter swimming are less likely to catch colds due to improved body temperature regulation function. It can also improve the body's endocrine function and increase pituitary gland function, thereby improving resistance and immunity to diseases.

3. Weight loss

Exercising in water can help many people who want to lose weight achieve twice the result with half the effort, so swimming is one of the most effective exercises to stay in shape.

4. Fitness

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.

【Swimming precautions】

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.

You cannot swim right after a meal or immediately after not eating, because swimming on an empty stomach will affect your gastrointestinal health, and you are prone to dizziness and fatigue while swimming. If you swim right after having a full stomach, it will cause vomiting and stomach cramps, as well as abdominal pain. I hope everyone will pay attention to this when swimming in the future.
