Entering winter, the air becomes increasingly dry, and many people are easily troubled by skin redness, swelling, itching, and other problems. Doctors remind that some patients, due to difficulty in accurately distinguishing symptoms of eczema, urticaria, and other diseases, blindly provide care, which can actually exacerbate discomfort. Skin problems occur frequently during seasonal changes, mainly related to impaired skin barrier function and external stimuli. If symptoms are self assessed and medication is ineffective, timely medical attention should be sought. By observing symptoms and their duration, common skin problems can be preliminarily identified. ”Lei Ming, Vice President and Deputy Chief Physician of Yinchuan Traditional Chinese Medicine Hospital, said that if suffering from eczema, there will usually be symmetrical erythema and papules on the calves, elbows, and other parts. In severe cases, there may be exudation, repeated itching, and symptoms may worsen after scratching. If the condition persists for a long time, the skin may become thicker; Contact dermatitis generally has a clear cause, such as changing skincare products or wearing jewelry, and its symptoms are mainly limited to the contact area. In addition to itching, it may also be accompanied by a burning sensation. Once the allergen is avoided, the symptoms will gradually improve. In addition, patients with urticaria may present with obvious wheals, which are red or pink edematous raised plaques of varying sizes and shapes, accompanied by severe itching. However, the wheals usually subside on their own within 24 hours of appearance. Be alert to emergency signals for some skin diseases. Doctors remind that patients with urticaria may experience severe allergic reactions throughout the body, such as difficulty breathing, tightness of the throat, rapid swelling of the lips, tongue, or face, dizziness, increased heart rate, decreased blood pressure, nausea and vomiting, severe abdominal pain, etc. They must seek immediate medical attention nearby. In addition, if the redness, swelling, and itching of the skin persist for a week without relief, affect sleep, or cause rupture or infection, timely medical attention should also be sought. The core of dealing with skin problems lies in "moisturizing and repairing". Doctors suggest that for elderly people or those with dry skin, the frequency of bathing should be reduced in winter, and the water temperature should not be too high; Use neutral or weakly acidic soap free shower gel and facial cleanser to avoid strong friction on the skin; Try to shorten the bathing time as much as possible, and apply moisturizing cream promptly after bathing; Indoor humidifiers can be used to maintain humidity, and wearing pure cotton clothing can reduce skin irritation. Lei Ming said that for skin diseases such as urticaria, patients can regulate their constitution through internal and external treatment methods such as oral Chinese medicine and traditional Chinese medicine therapy. Although they need to persist for a long time, it can effectively reduce the recurrence rate of the disease. At the same time, it is recommended to consume more foods rich in vitamin C and vitamin E in diet, supplement water in moderation, and help fragile skin survive the winter safely. (New Society)
