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.
