2. What should I pay attention to when taking a bath?

1, don't take too many baths.

Taking a bath with hot water and shower gel too frequently will reduce the sebum on the skin surface and make the skin slightly acidic, which is beneficial to the growth and invasion of bacteria. Middle-aged and elderly people are also prone to itchy skin, and even hinder hypoxia and ischemia of the heart and brain.

2. It is not advisable to soak in hot water for a long time when taking a bath.

The water temperature in the bath is higher than the body temperature. Soaking in water will speed up the heartbeat and increase the heart load. At the same time, with the increase of heart bleeding, the blood pressure of human body will also rise, which is easy to cause heart attack. Therefore, middle-aged and elderly people, especially patients with hypertension and heart disease, should not soak in hot water for a long time.

3. It is not advisable to rub your skin when taking a bath.

Excessive rubbing in the bath will destroy the protective layer of the skin and reduce the resistance of the skin, because there is a layer of keratinocytes on the surface of the skin, commonly known as "dead skin", with a thickness of only 0. 1 mm, which is weakly acidic and can block pathogens and harmful rays. It is the natural defense line of the human body. The update speed of this dead skin is relatively slow, and it takes more than ten days at the earliest, while it takes more than one hundred days on the inner side of the upper arm. Rubbing hard in the bath will destroy this line of defense, which will easily cause skin infection, folliculitis, boils and even septicemia. Therefore, it is not advisable to wipe the skin when taking a bath, not to mention wiping the skin with a dry towel or towel gourd tendon.

4. It is not advisable to take a hot bath after exercise.

During exercise, due to the exertion of muscles, the blood flowing to muscles increases, and the blood in myocardium also increases to meet the needs of exercise. If you take a hot bath as soon as you stop exercising, the blood flow of skin and muscles will continue to increase, thus reducing the blood supply of other organs of the body, especially the blood demand of the heart and brain, which may easily lead to heart attacks and brain hypoxia and accidents. Therefore, it is not advisable to take a hot bath immediately after exercise.
