Many people, especially the elderly, will have itchy skin after winter, so they keep scratching, hoping to relieve the itch. The more you scratch, the more itchy you are, the more itchy you are, forming a vicious cycle that leads to itching that never heals. So, in the winter, why does the human skin itch? This is because in the winter, especially in the north, the climate is dry, the air humidity is low, lack of moisture. The human skin is prone to dehydration in a dry environment. The skin of the elderly and those with dermatitis eczema is already dry, and they have problems with the barrier function of their skin and tend to lose moisture.

The lack of oil and water loss in the skin will lead to itching symptoms. After the itching of the skin, many people will subconsciously scratch. But scratching not only can not relieve the itch, but will give our brain central system a false signal that the skin is a problem, and will send a variety of inflammatory factors to “anti-inflammatory”, so that there is no inflammation of the skin instead of inflammation. In addition, repeated scratching will damage our skin barrier function, making the loss of water more serious, thus aggravating the symptoms of itching.
