The biggest advantage of practicing winter swimming is that it can enhance cardiovascular function. After the human body is stimulated by cold water, the blood circulation and metabolism of the whole body are greatly strengthened; People's skin is stimulated by cold water, and the blood vessels of the skin contract sharply, and a large amount of blood is sucked into internal organs and deep tissues, so that the blood vessels of important internal organs expand; In order to resist the cold, skin blood vessels expand rapidly, so a lot of blood flows from internal organs to the body surface. In this way, the blood vessels are exercised and the elasticity of the blood vessels is enhanced. Therefore, winter swimming is beneficial to the prevention and treatment of cardiovascular diseases. Among those who insist on winter swimming all the year round, people with arteriosclerosis and high blood pressure are extremely rare.

The stimulation of cold water makes the peripheral blood vessels of human body close, which ensures the increase of blood supply of important organs such as heart, brain, liver and spleen, and makes more oxygen delivered to brain cells in time, which is conducive to eliminating the fatigue of nervous system, which is not difficult to explain why most winter swimmers are mental workers.

When people come into contact with cold water, they will breathe in quickly, pause for a moment, then turn into deep exhalation, and then restore even and deep and powerful breathing. This kind of breathing can greatly improve the elasticity of lung tissue, inhale more oxygen, exhale more carbon dioxide and strengthen the function of respiratory system.

Most people feel hungry after swimming, and this feeling is more prominent among winter swimmers. Cold water can improve the function of human digestive system. Due to the deepening of breathing, the diaphragm fluctuates more, which accelerates the blood circulation in abdominal cavity, strengthens gastrointestinal peristalsis and plays a massage role on adjacent organs.

People who insist on winter swimming have rosy, shiny and elastic skin. The reason is that after cold water stimulation, skin blood vessels contract strongly, subcutaneous fat thickens, blood circulation is vigorous and nutrition is sufficient.

Winter swimming must have a hard-working spirit and tenacious perseverance. Perseverance is very important. As long as you retreat a little, you will give up halfway. If you don't insist on swimming for two or three weeks before you go into the water, it will be difficult for you to adapt mentally and physically, and you will face even greater difficulties.
