What are the pros and cons of swimming in winter?

Benefits of swimming in winter:

1. Helps blood circulation throughout the body. When swimming, the water can have a massage effect on the body. When the skin catches cold, it causes a vasoconstriction reaction, which can prevent and reduce the occurrence of arteriosclerosis, hypertension, diabetes, and cardiovascular and cerebrovascular diseases in middle-aged and elderly people.

2. It can improve cold resistance and immunity. Swimming promotes metabolism, thereby improving the body's resistance to cold, thus preventing respiratory diseases.

3. It can enhance the function of respiratory organs and reduce or prevent respiratory diseases that are prone to occur in winter. The density of water is 800 times greater than that of air. People have to endure a lot of pressure when swimming. Therefore, the respiratory muscles have to work hard to overcome the pressure of the water, deepening breathing and increasing lung capacity, thus enhancing the ability to adapt to environmental stimuli and reducing the risk of diseases. occur.

4. Regular participation in winter swimming has obvious effects on physical fitness and anti-aging.

5. It is a good weight loss exercise. Among all types of weight loss exercises, swimming is an exercise worth recommending to everyone. People who swim often have a toned figure, well-developed chest muscles, and a streamlined body shape; for people who can't swim, soaking in the water and having water fights will have some effect on losing weight.

The reasons why swimming is beneficial to weight loss are:

1. Swimming consumes a lot of energy. This is because the resistance of water during swimming is much greater than the resistance of air during land exercise, which is 800 times that of air. Walking in the water is laborious. If you swim again, you will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times greater than that of air, and the water temperature is generally lower than the air temperature, which is also beneficial to heat dissipation and heat consumption. Therefore, the energy consumed during swimming is much greater than that in land sports such as running, so the weight loss effect is more obvious. Winter swimming is a higher level of swimming, and the weight loss effect of winter swimming is particularly obvious.

2. Swimming can avoid sports injuries of lower limbs and waist. When doing long-distance running to lose weight, obese people have a heavy weight, which puts a heavy burden on the body (especially the lower limbs, waist and heart), which reduces exercise ability, makes them prone to fatigue, greatly reduces interest in weight loss exercise, and can damage the joints of the lower limbs. , skeleton and heart. When swimming is carried out in water, a considerable part of the obese person's weight is borne by the buoyancy of the water, which makes the lower limbs and waist much more relaxed, and the risk of joint and bone damage is greatly reduced.

3. You can enjoy natural massage services. When swimming, the buoyancy, resistance and pressure of the water are an excellent massage for the human body and can also have a beautifying effect on the skin. In view of the above reasons, obese people can indeed use swimming as their main weight loss exercise. But before swimming, you must make preparations and pay attention to safety to prevent accidents.

Winter swimming is being accepted by more and more people and has become a fashionable way of exercising. However, although winter swimming can keep you fit and prevent diseases, it must also be scientific. Not everyone is suitable for winter swimming, especially patients with severe heart disease, high blood pressure, and skin diseases.

Winter swimming is good but not suitable for everyone:

Winter swimming is called "a game for the brave", and more and more winter swimming enthusiasts are jumping into the cold and biting water. Show "heroic qualities". However, Zhang Baocang, director of the Winter Swimming Committee Office of the Chinese Swimming Association, said in an interview that although winter swimming has many benefits, it is not suitable for everyone.

Three groups of people are not suitable for winter swimming:

1. Teenagers under 16 years old and elderly people over 70 years old are not suitable for winter swimming due to their special physical conditions;

2. Mentally unsound patients are not suitable for winter swimming due to lack of self-control;

3. In addition, after medical examination, patients with serious organic diseases such as heart disease, coronary heart disease, tuberculosis, hepatitis, and stomach disease People with respiratory diseases are not suitable for winter swimming.
