We generally like to take a hot bath, but some people like to take a cold bath. They think that it will improve the body's constitution, strengthen the skin, strengthen immunity, promote blood circulation and other functions. Taking a cold bath really has many advantages. Let's have a look.

1、 Can improve the function of nervous system

Cold water bath is a kind of strong benign stimulation, which can improve the excitability of central nervous system and make all systems of human body active. It can also enhance the blood circulation and metabolism of the whole body, and more oxygen is sent to brain cells, which is conducive to eliminating brain fatigue, invigorating the spirit and filling the mood.

2、 Healthy and beautiful skin

Cold water bath can strengthen the nutrition supply of skin and subcutaneous tissue, increase the secretion of sebum, make the skin rosy, glossy and elastic, and is not easy to suffer from skin diseases. Health Tip: a cold bath is not for everyone. Cold bath exercise should not be carried out immediately after an empty stomach, after a meal or after strenuous exercise. Cold bath is not suitable for people with skin wounds, weak constitution and fever. In addition, people with cold water skin allergy, severe hypertension, coronary heart disease, rheumatism, tuberculosis and sciatica should not take cold water shower.

3、 Can

4、 Can enhance cardiovascular function

When the body is stimulated by cold water, the blood vessels on the surface of the skin will contract sharply, and a large amount of blood will flow to the internal organs of the body, which will increase the blood of the internal organs. In order to resist the cold, the blood vessels of the skin will soon expand, and a large amount of blood will flow to the body surface, making the skin red. The elasticity of blood vessels increases as they contract. So some people call cold water bath "vascular gymnastics". It has been proved that cold water bath is helpful to prevent hypertension, normal metabolism, fat accumulation and cholesterol deposition on the blood vessel wall and arteriosclerosis.

5、 Strengthen immunity

According to a 1993 study by the thrimbosis Research Institute in the UK, those who take a cold bath every day have more antiviral white blood cells in their blood than those who take a hot bath. Experts believe that cold water bath promotes metabolism. That may be because the body, in order to keep warm, activates the immune system and thus releases white blood cells.

6、 Promote blood circulation

Good blood circulation is crucial to the overall health of the heart and blood vessels. Having a healthy blood circulation can quickly help you recover from fatigue after strenuous exercise. It is easy to wash with hot and cold water alternately in shower, which can improve blood circulation. In order to keep the organs warm, a lot of blood will flow into the organs after flushing cold water. Warm water has the opposite effect. Promote blood flow to the skin surface. Compared with warm water bath, cold water bath can stimulate circulation system, make people healthier and look younger.

Although there are many advantages of cold water bath, not everyone is suitable. People with fever and weak constitution are not suitable for cold water bath. People with rheumatism, hypertension, coronary heart disease and other diseases are also not suitable for cold water bath. People are not suitable for cold water bath either on an empty stomach or after meals.
