The causes of neurodermatitis aggravated in summer include sun exposure, high temperature, high humidity environment, and sweat impregnation. Neurodermatitis is a common skin disease, the cause of which is still unclear, mainly related to scratching and chronic friction, in addition, it may also be related to emotions, diet, local irritation and so on. In addition, the environmental temperature and humidity are higher in summer, and the ultraviolet rays are stronger, which may lead to the aggravation of neurodermatitis. At the same time, easy sweating in summer causes sweat impregnation, and this local irritation can also cause aggravation of neurodermatitis. Neurodermatitis patients should develop good bathing habits in the summer, bathe with warm water, strengthen the local skin moisturizing, keep the skin cool and moist, and try to consume as little photosensitive food as possible, such as wild vegetables. Try to avoid rubbing and scratching the skin.
