The skin is dry and itchy in winter! What's going on here?

Hello ~! The key to itchy skin in winter lies in dry and cold skin, lack of water and anemia, which makes the skin thick and rough. In autumn and winter, the sebum and water secretion of the human body will gradually decrease, and the skin will obviously become dry, especially for middle-aged and elderly people. Because of the large reduction of water, the surface of the skin will appear rougher and drier, and hands, feet, limbs and calves will often be chapped and itchy. When they can't stand dry itching, they will keep scratching, causing skin wounds, inflammation or pus. Therefore, to maintain a certain humidity in the house, you can put some green potted plants or a basin of water to increase the air humidity. When the skin is dry, don't rub it in the shower, and don't use too much soap to avoid scratches. After bathing, you can apply moisturizing lotion all over your body to keep your skin moist. It is recommended to apply moisturizing cream or moisturizing lotion every day. If necessary, you can also take the first generation of anti-allergic tablets orally to achieve the effect of relieving itching and calming down. Try to eat more foods rich in vitamin A, such as carrots and cabbage, and eat less coffee, cola and hot and sour food.
