Is winter travel good for your health?

Swimming is a very popular sport. Although the conditions are somewhat harsh, learning to swim is not a very difficult thing. Moreover, swimming can bring great benefits to the human body. While strengthening the body, it also has the effect of preventing diseases. Winter swimming is very popular in many areas, and one has to admire these people's ability to resist the cold. So, is winter travel good for the human body?

Can enhance cardiovascular function. When the human body is stimulated by cold water, the blood circulation and metabolism of the whole body are greatly enhanced; when the human skin is stimulated by cold water, the skin blood vessels contract sharply, and a large amount of blood is sucked into the internal organs and deep tissues, causing the blood vessels of important internal organs to expand; in order to resist the cold, the skin blood vessels expand again quickly, and a large amount of blood flows from the internal organs to the body surface. This characteristic expansion and contraction exercises the blood vessels and enhances their elasticity. Therefore, winter swimming is beneficial for preventing and treating cardiovascular diseases. Among those who insist on winter swimming exercises all year round, it is extremely rare for people to suffer from arteriosclerosis, hypertension and the like.

The stimulation of cold water causes the human body's peripheral blood vessels to close, ensuring more blood supply to important organs like the heart, brain, liver, and spleen, allowing more oxygen to be delivered to brain cells in a timely manner, which helps eliminate fatigue of the nervous system. When the human body comes into contact with cold water, it will inhale rapidly, pause for a moment, then exhale deeply, and then resume even, 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 the respiratory system. Cold water can improve the function of the human digestive system. As breathing deepens, the diaphragm can rise and fall more, thereby speeding up blood circulation in the abdominal cavity, strengthening gastrointestinal motility, and massaging adjacent organs.

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

Although winter swimming has many benefits, it is not suitable for everyone. Zhang Baocang said that research shows that there are three groups of people who are not suitable for winter swimming: teenagers under the age of 16 and the elderly over 70 years old are not suitable for winter swimming due to their special physical conditions; mentally ill patients are not suitable for winter swimming due to their lack of self-control; in addition, according to doctor's examination, people with serious organic diseases such as heart disease, coronary heart disease, tuberculosis, hepatitis, stomach disease and respiratory diseases are also not suitable for winter swimming.
