Now into the autumn, due to the cooler weather, dry climate, easy to lead to a decline in human resistance, but also the high incidence of certain skin diseases season. Pruritus is a common skin disease in autumn and winter, itching is not a major disease, but itching is really annoying, serious will also affect people’s rest and sleep. The majority of patients should be under the guidance of a doctor’s reasonable diagnosis and treatment, do not take the initiative to deal with the serious consequences. There are many reasons for itchy skin, the main reason is dry skin. After the weather turns cool, the human sebaceous gland secretion begins to reduce, the skin is easy to dry. In addition, coupled with some external stimuli, such as laundry detergent, alkaline soap, etc., can cause the loss of sebum, disturbing the water-lipid balance of the skin surface and cause itching. The sebaceous gland secretion function of the elderly decreases with age, and the skin is drier, so this disease is mostly found in the elderly. Pruritus is divided into two types of pruritus: generalized pruritus and localized pruritus. Generalized pruritus is often paroxysmal, especially at night. Due to the intense itching, long-term poor sleep, there will be dizziness, depression, loss of appetite and other symptoms of neurasthenia. Localized pruritus occurs in one part of the body, with the anus, scrotum and female genitalia being the most common. If the pruritus is not treated properly, it can lead to different degrees of eczema changes in the skin, manifested as skin papules, blisters, and even vesicles and oozing, recurrent episodes, and the disease can be chronic for a long time. Therefore, it is recommended that patients with itchy symptoms do a good job of prevention and treatment under the guidance of a specialist. First, to remove the cause of the disease, timely treatment of associated diseases. Second, pay attention to “avoid mouth”. In terms of diet, try to eat more herbal porridge that strengthens the spleen and nourishes the blood, limit the consumption of strong tea and coffee, and try not to eat fish, shrimp, wine, chili peppers and other foods to avoid aggravating the disease. Third, do not make the room temperature too high when heating in autumn and winter, and use humidifiers or planting flowers and plants to maintain the appropriate humidity in the room to reduce the evaporation of skin moisture. In addition, you should also develop the habit of drinking water regularly and quantitatively. The human skin is an important “reservoir” for the body to store water, if you always drink water when you feel thirsty, people will often be in a state of dehydration, and once the body is dehydrated will take water from the skin. Fourth, avoid local stimulation. Avoid using hot water, towels, soap to rub hard and inappropriate topical drugs, because this will wash off the skin surface of the lipid film, so that the skin dry and aggravate the itching. After each bath, in often feel itchy parts of the appropriate application of some containing a small amount of oil emollient, snow cream, etc., can effectively reduce itching. Fifth, topical medication can be used according to the condition of the furnace glycolate lotion containing anti-itching agents, corticosteroid ointment or cream, as well as creams containing anti-itching agents. Sixth, those with severe itching or poor results of external medication can take some drugs internally. We should also be reminded to restrain scratching, scratching not only breaks the skin, prone to infection, and long-term repeated scratching will make the local skin become hypertrophic, rough, the local sensory nerves are more excited and sensitive due to repeated stimulation, making itching further aggravated. This will step into the vicious cycle of the more itchy the more scratching, the more scratching the more itchy. The local skin peeling, itching can not be careless, many patients for the sake of the road a moment, using hot water, irritating lotion rubbing and other incorrect methods to deal with, which will only exacerbate the further weakening of the epidermal barrier function, so that the discomfort aggravated. If there is a discomfort in time to go to the hospital to find a specialist to deal with, must not handle indiscriminately.
