Bathing can not only remove sweat and oil stains, relieve fatigue, relax muscles, promote blood circulation, improve sleep, improve skin's metabolic function and disease resistance, but also treat some diseases by soaking in warm water.
Of course, the water temperature of a hot bath should not be too high, and generally warm water of 35 ~ 40℃ is appropriate. The number of times of washing should not be too much, because too many times will wash off all the oil normally secreted on the skin surface and the protective flora normally parasitic on the skin surface, which will easily cause skin itching and other diseases, and the skin's resistance will be weakened, but it will easily get sick.
No matter which season, the bathing time should not be too long, and the bathing time should be 15 ~ 30 minutes each time to prevent hypoxia and ischemia of the heart and brain. In summer, the human body is vigorous and perspires a lot, so you should wash it once a day. The weather is not hot in winter, spring and autumn, and the number of baths can vary from person to person. Those who are obese and have exuberant sebaceous glands can appropriately increase the number of baths. The secretion of sebaceous glands in the elderly is reduced, and the number of baths can be appropriately reduced.
You can't take a bath when you are full and hungry. Take a bath after eating. The blood vessels in the epidermis of the whole body are stimulated by hot water to expand, more blood flows to the body surface, and the blood supply in the abdominal cavity is relatively reduced, which will affect digestion and absorption, cause hypoglycemia, and even collapse and faint. People who have drunk alcohol can't take a bath either, because alcohol can inhibit liver activity and hinder the recovery of glucose in the body. When taking a bath, the glucose consumption in the human body will increase. If you take a bath after drinking, your blood sugar can't be replenished in time, and you are prone to dizziness, general weakness, and even hypoglycemia coma in severe cases. ?
No matter after physical or mental work, you should have a rest before taking a bath, otherwise you will easily faint.
