If the climate is dry, taking a shower too seriously is not good.

　　1. Bathing time should not be too long

　　Many people are afraid that they will not be clean every time they take a bath. The bathing time often exceeds half an hour, or even an hour in some cases. Washing for too long will definitely wash away a lot of the sebum film on the surface of the human body, which lacks the protection of the sebum film. skin The skin will become drier and flaky, followed by incessant itching. Therefore, it is recommended that people should not take a bath for too long, preferably about 10 minutes.

　　2. It is not advisable to wash with hot water

　　Thermal stimulation can suppress itching, so most patients with pruritus like to "scald" with high-temperature water. elderly Even scald with salt water or pepper water. Doing so will feel very "comfortable" and "relieve itching" at the time, but it will dissolve the protective film on the skin surface, making the skin drier and aggravating the itching. The water temperature during bathing should be 40°C.

　　3. Don’t be too “serious””

　　Since the sebum film is very important for protecting the skin, the elderly have dry skin and the sebum film is not abundant, so bathing once a week is enough. And those who like to take a bath every day should not be "serious" and "thorough" every time to avoid removing too much of the sebum film. In addition, try not to take a bath, let alone use alkaline soap to wash your body.

　　4. It is not advisable to rub the bath vigorously

　　Many young people like to use saunas and rub themselves vigorously until their bodies turn red. In fact, the "mud" they rub off is a protective film for their skin. Frequent hot water soaking and scrubbing can cause excessive shedding of normal keratinocytes, thinning the sebum film, and excessive destruction of the skin barrier protective function. The skin will also become more itchy after the "mud" is rubbed away.

　　For some people with dry skin, after taking a shower, it is best to apply an appropriate amount of moisturizing product with skin moisturizing function on the body within 5 minutes. The external "moisturizing factor" can be used to maintain skin moisture, prevent dry skin and dandruff, and reduce the occurrence of skin itching. After each bath, try to wear soft cotton underwear instead of wool or man-made fiber to avoid skin irritation. Once itching occurs, you can pat or rub it with your fingertips to relieve the itching. Try to avoid scratching with sharp nails, because scratching can make the local area feel itch. nerve Due to repeated stimulation, the patient becomes more excited and sensitive, which further aggravates the itching, thus forming a vicious cycle of the more itches, the more it is scratched, and the more it is scratched, the more itchiness becomes.
