bath is also called bath. In China, bathing is a major event. Since ancient times, there has been a saying that bathing is in the Dynasty and fasting and bathing is in worship. In fact, bathing is not only cleaning the body, but also a kind of exercise. The Tang Dynasty book tianyinzi described: “fasting is not just a vegetable and Ru diet; A bath is not just a soup bath to remove dirt. The benefit method is in the diet adjustment, and the friction is smooth. ” It means that fasting is not only to abstain from meat and vegetables, but also to reconcile the spleen and stomach through dieting; Bathing is not only to wash away the dirt with hot water, but also to smooth the human skin and blood circulation by rubbing the skin. It fully points out the dual functions of bath descaling and fitness. Bathing is divided according to the temperature of water, including hot water bath, cold water bath and hot and cold water bath. These bathing methods have different health care effects.

1. Hot water bath can eliminate body fatigue

the Japanese call hot water bath “soup bath”, also known as “bubble soup”, and often “bubble” together with the whole family. When you are in the bath, the 40 ℃ water behind you is gurgled into the stone trough, and your physical and mental fatigue disappears.

fatigue is related to the concentration of lactic acid in human blood. Washing warm water bath can accelerate metabolism, improve the speed of decomposition of lactic acid and eliminate fatigue. Taking a bath for 20 minutes is equivalent to jogging for 500 meters. Therefore, taking a bath also has the effect of fitness. However, the higher the water temperature of the warm water bath, the better. Otherwise, excessive sweating will easily lead to collapse. The water temperature should be controlled at about 38 ℃.

2. Cold water bath can enhance cold resistance

Mr. Xu Teli, Mao Zedong’s teacher, has experienced the vicissitudes of life, but still enjoys a 92 year old high life. Among them, cold water bath is indispensable, which is called “the battle of revolutionaries”. After getting up, old Xu wiped his head and face with cold water, then his neck, chest and back until his skin was red and hot. Whether it is spring, summer, autumn or winter, it never changes. Cold water bath can improve the cold resistance of human body and exercise vascular elasticity. It is a “vascular gymnastics”.

it should be reminded that cold water bath has an adaptation process. If you always take a hot bath and suddenly take a cold bath, it will not only be useless, but will get sick.

III. hot and cold water bath can maintain vascular elasticity

Mr. Ma Yinchu is a famous demographer, educator and economist in China, the former honorary president of Peking University, and an old birthday man who has lived to 101 years old. In his early years, he was weak when he studied in the United States. Later, he was lucky to meet a 93 year old doctor who was still pale. The doctor told him the secret of his fitness: hot and cold bath. First take a hot bath for a quarter of an hour to smooth the meridians around the body, then dry the body, rest for a few minutes, and then quickly take a cold bath for a few minutes. Since the application of this exercise method, Ma Yinchu has always been very healthy, even with very few colds.

hot and cold water bath can make blood vessels relax, expand and contract with heat, and maintain blood vessel elasticity, which is very good for maintaining normal blood pressure and preventing cardiovascular diseases.

IV. precautions during bathing

1. Drink an appropriate amount of water before and after bathing, which can promote body fluid circulation and eliminate toxins in the body.

2. When bathing, the water temperature should not be too high. The bath water temperature should be maintained at about 40 ℃, and the single bath time should be controlled at 15 minutes. It’s best not to exceed 20 minutes. If the time is too long, it is easy to wrinkle and dry the skin. The elderly especially need to pay attention.

3. The best bath time is generally between 3 p.m. and 9 p.m., which is more conducive to skin relaxation and adjustment.

4. The use of scrub bath products can help remove dead skin on the skin, but the strength should not be too great. Such products should not be used every day. 2 ~ 3 times a week is enough.

5. The maintenance after bathing is also very important. The bath milk can help lock in the moisture of the body and make the skin more radiant.
