It itches and hurts! One, two, three common skin diseases in winter

In winter, some people often scratch because of itchy skin, and even scratch their skin and bleed a lot. Mainly because of the dry weather in winter, skin moisture is easy to lose and sebaceous gland secretion is reduced, so it is easy to cause dry skin and nervous sensitivity, and it is easy to induce some winter itching, including eczema, rich hands, athlete's foot, atopic dermatitis, scalp itching and skin hypertrophy.

In winter, the climate is dry, and skin moisture is easily lost. Patients should pay more attention to moisturizing and avoid "winter itching". Xie Jiaxian, a dermatologist at Renai Hospital of Taipei United Hospital, said that sebaceous glands will degenerate with age and secrete less oil, which is easy to occur in the skin of middle-aged and elderly people, especially in the lower limbs. In winter, when the temperature drops, the blood vessels of the skin contract, which leads to the decrease of skin water content. In addition, the secretion of sebaceous glands and sweat glands decreases, and water is easy to volatilize because of the lack of water retention function of lipid layer. Moreover, the air humidity is also low, and the skin begins to produce dryness, tightness, itching and even peeling, which is called "winter itching".

In winter, dry itching usually occurs in dry skin and middle-aged and elderly people. Because the skin lacks sebum and is relatively dry, the colder the weather, the more serious this situation will be. Usually there is only itching at first, but gradually it may lead to skin inflammation, rash, eczema and even bacterial infection.

Generally, the symptoms of eczema are small red rash and severe itching, because if you scratch all the time, you will get small papules. If you keep scratching, you may scratch these rashes and shed serous fluid. When the slurry dries, it will form a skin. If you peel off these skins, serous water will appear again, and so on.

For patients with atopic dermatitis, in winter, due to lack of water, the symptoms of dry itching will be more serious, and patients will easily scratch because of unbearable itching, leading to skin inflammation and even bacterial infection.

When women reach puberty, due to the effect of hormones, a thick stratum corneum will appear in the heel. With the increase of age, the stratum corneum will gradually increase. If the stratum corneum is not treated, it is easy to dry in winter because of dehydration. In severe cases, it will even crack and bleed, which will be very painful.
