Is swimming really good for your skin?

Swimming is a very popular sport. In summer, many people like underwater sports. Swimming can not only exercise the body, but also relieve heat. However, many people also like winter swimming. Although the temperature is relatively low in winter, some people choose to swim as a way of exercise. There are many benefits of swimming. Let me introduce to you the specific benefits of swimming.

Improve the function of the cardiovascular system

If you persist in long-term swimming exercises, the volume of the heart will increase, the myocardial contraction will become stronger, the resting heart rate will slow down, the stroke volume will increase, the blood vessel walls will thicken and increase their elasticity, and the efficiency of the cardiovascular system will be improved.

Improve the function of the respiratory system

Because the density of water is more than 800 times greater than that of air, the pressure a person is subjected to in water is much greater than that in air. As the pressure on the chest and abdominal cavities increases in water, the respiratory muscles are forced to use greater force to breathe. Regular swimming can increase the strength of the respiratory muscles and improve the function of the respiratory system.

Improves the strength of the muscular system

Swimming is a sport that involves the whole body. Long-term training can improve muscle strength, speed, endurance and joint flexibility. Correct swimming technique requires muscles to stretch before contracting and exerting force. This type of exercise is conducive to continuously improving our flexibility and strength.

Make the body proportions more reasonable and shape a healthy body

The process of swimming creates resistance with water, which has the effect of losing weight. People who swim for a long time generally have a slender figure, broad shoulders, flexible waist and well-proportioned body shape.

Improves body temperature regulation

Since the temperature of water is generally lower than the air temperature and the thermal conductivity of water is dozens of times stronger than that of air, people lose much more heat in water than in the air. Regular swimming can improve the body's ability to regulate temperature, making it better able to withstand changes in external temperature.

The article introduces many benefits of swimming. After understanding these benefits, if you want to exercise by swimming, you can try it. Of course, it may be difficult to learn to swim. It is recommended that you exercise under the supervision of someone and a coach, and do not swim in a river or reservoir casually.
