However, although cold water bath can strengthen the body and get rid of diseases, exercise must be moderate, otherwise it will be counterproductive. Zou Xianbiao, chief physician of the Department of Dermatology, 304 Hospital of the People's Liberation Army, told the reporter that several points should be paid attention to when taking a cold bath:
First of all, people who have never taken a cold shower before, if they suddenly take a cold shower, will make their blood vessels contract, their body temperature drop, and their bodies catch cold, leading to colds. Therefore, taking a cold bath should start in summer, last from summer to autumn, and last until winter, and it is best not to interrupt during the period.
Secondly, it is best not to take a cold bath, because the respiratory system is concentrated there, which is easy to cause respiratory diseases due to catching cold. When taking a cold bath, you should keep your head dry.
Third, because the water in the north is cold in winter, unlike the water in the south, the temperature is not very low. Taking a bath with very cold water will cause frostbite and frostbite to the skin after a long time, so the time for taking a cold bath varies from person to person and from time to place. Not too long. The lower the temperature, the shorter the water bath time. Wash for 3-5 minutes at most in winter. And after taking a bath, dry your body with a dry towel and rub red.
Finally, take a cold bath when you are in good health, and stop taking a cold bath when you have a cold and feel unwell.
To put it simply, taking a cold bath has three advantages. First, it increases the adaptability of human body to temperature, especially to cold air, and it is not easy to catch a cold. Second, it is good exercise for human blood vessels. When taking a cold bath, the blood vessels contract rapidly, and a large amount of blood flows to the inside of the body and then to the body surface, and the blood vessels expand and contract. In the long run, it can prevent cardiovascular diseases. Third.
Hazard: Different personal constitutions will lead to different diseases.
Matters needing attention in taking a cold bath
Take a bath every day in summer. Many people take a cold bath to save trouble, and some people take a cold bath to keep fit. Cold water bath has many functions. For skin, it can make blood vessels contract first and then expand, improve blood circulation efficiency, enhance skin nutrition, make subcutaneous tissue accumulate certain fat, and make skin look young and elastic, and it is not easy to suffer from skin diseases. Cold water bath can exercise skin temperature receptors and eliminate abnormal sweating. For the whole body, cold water bath can improve the body's rapid adaptability to cold, and it is not easy to suffer from cold-induced diseases such as cold, bronchitis, tonsillitis, pneumonia and allergic rhinitis. Cold water bath promotes blood circulation between skin and viscera. The expansion and contraction of blood vessels exercise the elasticity of blood vessels, which can prevent arteriosclerosis and its diseases, such as coronary heart disease and hypertension. Cold water bath increases the blood flow of visceral blood vessels, including digestive tract blood vessels, thus strengthening the function of digestive system. When cooling with a cold water bath, it is not advisable to suddenly immerse in cold water at first. It is best to splash some cold water on your body with your hands or shower head, or wet your hands and feet with cold water first, and then wet your chest and back with a towel. Rub your body for a while, cold water will soak you through and dry quickly until your skin turns red, which means the effect is good. If you feel cold, you should shorten the shower time or raise the water temperature.
The following kinds of people should not take a cold bath.
(1) Patients with hypertension: When the skin comes into contact with cold water, the blood vessels contract sharply, and a large amount of blood rushes back to the internal organs, making the already high blood pressure even higher. In severe cases, it can cause cerebrovascular rupture, bleeding, stroke, coma and even death. People with slightly elevated blood pressure can take a cold bath, but only slowly, that is, sprinkle some cold water first and rub some parts of the body instead of "cold treatment" at once.
(2) Patients with sciatica and arthritis: After the nerves catch cold, the condition will be more serious.
(3) People who are allergic to cold, such as patients with cold urticaria and pruritus, should not take a cold bath during the onset. If you want to exercise your skin when you don't have an attack, it is feasible to gradually cool down, that is, take a hot bath at first, gradually switch to a warm bath, and then gradually lower the water temperature until the water temperature is quite low but you don't get sick.

Long-term continuous cold bath exercise will not only increase the elasticity of blood vessels, but also prevent arteriosclerosis, colds, bronchitis, tonsillitis, pneumonia and so on.
