Taking a bath every day in winter is easy to hurt the skin, and it is dry in winter. It is more appropriate to take a bath two or three times a week. Because of the need of work or the change of living habits, many people are used to taking a bath once or twice a day. However, with the arrival of winter, the air is getting drier and drier, and skin itching begins to bother these "daily bathers". Many of them even think that itchy skin means that personal hygiene is not in place, so bathing is more diligent and thorough, but the degree of itchy skin is aggravated. Medical experts remind people that taking a bath too often will hurt the skin, and the resulting skin itching is inevitable. In this season, it is more appropriate to take a bath 2-3 times a week. If the habit of bathing many times a day is not easy to change, you should pay more attention to the method of bathing. Itching of the skin may be caused by taking a bath too often. Liu Shouquan, chief physician of dermatology department of Beijing Sixth Hospital, has recently received many such patients. He usually pays great attention to personal hygiene, but he often feels itchy all over, most of whom are young and middle-aged "white-collar workers". According to Dr. Liu, with the improvement of people's living standards and housing conditions, many families have the conditions to take a bath at any time, and some skin diseases caused by too frequent bathing have also increased, the most common of which is always feeling itchy skin. For most people who work in poor sanitary conditions, taking a bath every day in dry winter can easily destroy the normal skin structure. The outermost layer of human skin is the stratum corneum, and there are not many skin scales mixed with skin sweat. Wash this part off every day, which has a certain protective effect on the skin. Taking a bath too often, the cuticle is damaged, and the protective effect on the skin is lost. The water in skin cells is more likely to evaporate and the skin is dry. Traditional Chinese medicine believes that "dryness leads to wind, and wind causes itching", in which "wind" refers to a cause that wanders in the body, leading to itchy skin. Wrong habits aggravate the degree of itching. Many "day bathers" have this experience, and itching often strikes at an inappropriate time. For example, when you are in a meeting, driving or meeting a client, you will suddenly feel a strange itch in a certain part of your body. It was not convenient to scratch at that time, so I had to endure it. Once you get home or alone, you will scratch quickly. You always think that scratching your skin will make you happy, but scratching too hard will make your skin get acne. Some people are used to scalding itchy parts with hot water, thinking that this can relieve some. However, these methods of relieving itching are incorrect, which will cause great harm to the skin in different degrees, but will aggravate the degree of itching. Moreover, it is easy to cause bacteria and parasites to inhabit, and even cause diseases such as skin inflammation and ulceration. Therefore, whenever this time, the best way is to stop itching with a cold towel soaked in cold water. Some "people who take a bath every day" only feel that a certain part itches unbearable at a certain time or under certain circumstances. Dr. Liu said that such a situation is generally caused by psychological factors. For example, it is usually at home or alone, because you can scratch at will. This condition is called cutaneous neurosis, and you will feel it when you have a chance. Doctors suggest that people who itch due to psychological factors should pay attention to self-restraint. When it comes to the time or environment of itching, they should try to divert their attention and force themselves not to think about it. Cai Nianning, director of the Leather Research Center of Beijing Hospital of Traditional Chinese Medicine, suggested that it is not necessary to take a bath every day in winter. If for some people, the habit of taking a bath every day is not easy to change, then we should pay special attention to the method of taking a bath. First, the water temperature is 24-29℃. If the water temperature is too high, the oil on the skin surface will be destroyed more easily, and the capillaries will expand, which will aggravate the dryness of the skin and bring harm to the skin. It will also increase the burden on the heart. Second, the bath time should not be too long. Take a bath for 20 minutes and shower for 3 to 5 minutes, otherwise the skin surface will be dehydrated easily. Third, if the skin is not very oily, it is better to choose neutral bath and soap, but you don't have to use it every day, just once every two or three days. And it is not advisable to stay on the body for too long, so it must be rinsed clean, otherwise it will hurt the skin. Fourth, after taking a shower, apply lotion all over the body, which can lock the moisture on the skin surface and relieve dryness and itching. Fifth, eat less spicy food such as beef and mutton, onion and garlic, and at the same time drink less and smoke less. If the dryness and itching of your skin are still not relieved after adjusting the number of baths and the way of bathing, it is best to ask a doctor to diagnose your skin and prescribe the right medicine.
