Every year in winter there are some elderly people come to see the pruritus, itching, seriously affecting sleep. On their own, they use hot water to wash and scratch, and as a result, their condition gets worse and worse. I often describe this disease as a degenerative change of the skin, and like bones, sclerosis will occur with age. The skin also ages, sebum secretion decreases, the skin becomes dry, and itching occurs. So wash more will be more dry, you should use moisturizing skin care products, increase skin moisture, humidity increased, itching will naturally reduce, you can try.
