Whenever the seasons change the skin is the first to suffer, autumn is the season of climate change, the temperature difference between morning and evening, human resistance encountered a great challenge, if not protected, the skin is prone to a variety of problems. Pruritus enters the autumn, the human sebaceous gland secretion weakens, the skin is dry, easy to appear tiny cracks, resulting in itching. Pruritus is the most common skin disease in autumn and winter, divided into two kinds of generalized itching and localized itching. Systemic pruritus is often paroxysmal, especially at night; localized pruritus occurs in a part of the body, called “itchy spots”, the cause of which may be one of the manifestations of neurosis, but also may be an early manifestation of visceral disease in the skin. For patients suffering from this pruritus, and every season when the disease is heavier, it is recommended to take preventive measures during the change of season: try not to eat fish, shrimp, wine, chili peppers and dry food, so as not to aggravate the disease; minimize contact with items containing chemical ingredients, such as detergents, cleaning agents; itchy skin, do not scratch excessively or wash with boiling water, can rub some ointment or take some anti-allergy drugs; bathing should not be Excessive washing, after bathing the whole body to apply emollient cream, so as not to dry skin pruritus occurs. The elderly due to atrophy and degeneration of skin appendages, sebum secretion is reduced, more attention should be paid not too diligent bathing. For the elderly who are prone to cracked hands and feet, you can use Vaseline, snake oil cream, cold cream, balsam and other thicker creams for better moisturizing effect, and use more times than the number of hand washing. Urticaria Urticaria is folk called wind rash block, wind bumps. It is the most likely skin disease to occur in autumn. The cause is complex, but is closely related to environmental stimuli. For example, food, drugs, insect bites or inhalation of pollen, feathers, dander, etc., while hot and cold stimuli, sun exposure, friction and pressure can also cause the disease. Acute urticaria usually has an acute onset, often after eating seafood, medications, etc. The skin suddenly becomes red, swollen, and itchy, and a rash of various shapes, large and small, begins in isolation or scattered, and gradually expands and fuses into patches. Most of these rashes will subside spontaneously within 24 hours, but new rashes occur one after another, one after another. In severe cases, there are symptoms of anaphylaxis such as panic, irritability, nausea, vomiting, and even lowered blood pressure, etc. Some patients also involve the stomach and intestines, causing abdominal pain and diarrhea. If the throat is involved, breathing difficulties and even choking can occur. In addition to food allergies that can easily cause hives, cold air changes in autumn can also cause hives. Some people get itchy skin when they blow cold air every fall, and even when they touch cold air, water or cold things, their exposed skin or parts that touch cold things produce rash blocks, and in heavy cases, they also get numb hands, numb lips, chest tightness, heartburn, abdominal pain, diarrhea, fainting and even shock, which is called “cold urticaria”. In some cases, cold urticaria is not simply a skin disease, but a symptom caused by other diseases, such as cryoglobulinemia, paroxysmal cold hemoglobinuria, cold fibrinogenemia, and cold hemolysis. In addition, because the skin is affected by the autumn climate and becomes dry, people sometimes scratch because of itchy skin, which may cause artificial urticaria. This means that after scratching the skin with the hand or scratching it with a blunt instrument, striated elevations occur along the scratch marks, accompanied by itching, which soon subside. Herpes of the mouth and lips In addition to dry skin, dry throat and sore throat, and dry stools, the incidence of “rotten mouth” is also significantly higher in autumn. Many people think that “rotten corners of the mouth” is caused by autumn dryness, which belongs to what Chinese medicine calls Yang evil, and consider themselves to be “on fire” symptoms, so they like to drink some herbal tea to clear heat and detoxify “fire”. “. In fact, “rotten corners of the mouth” is herpes simplex virus type I (HSV-Ⅰ) infection, the scientific name is “oral lip herpes”. The use of antiviral drugs like acyclovir, which has a special affinity for the herpes virus, is therefore more effective than heat-clearing and detoxifying herbal medicines, both internally and externally. Especially in the early stage of symptoms, when the patient has just started to feel a slight painful itch or red rash around the lips, the drug should be used immediately, when the number of viruses is not too much, the herpes is not yet fully developed, the lesions have not yet appeared, the virus is easily and quickly cleared, and the course of treatment can be significantly shortened. As herpes is a self-limiting viral infection, it can be cured after a week even without treatment as long as there is no secondary infection, so many patients do not pay attention to it and do not have early treatment and complete the whole course of treatment as prescribed by the doctor, which is one of the main reasons why herpes is recurrent in the future. If the herpes is recurring more than 5 times in a year, it means that the immunity of the patient is already relatively low and should be given high priority, timely conditioning and changing bad habits. Tips autumn is one of the high incidence of skin disease season, after autumn people should eat more fresh vegetables and fruits, less fried hot and spicy products, proper exercise, ensure sufficient sleep time, keep emotionally happy, learn to relieve stress, drink more water, drink more honey, milk, lily silver fungus lotus seed soup and other nourishing drinks, do a good job of skin hydration and moisturizing. Finally, once you have a skin disease, you should actively look for the cause of the disease and seek medical treatment in a timely manner.
