Since July, there are more than 400 patients in skin clinic in Beijing Chao-Yang hospital everyday, sometimes more than 500 patients. Doctors find that patients have increased this year compared with those of the same period last year. The most common disease in skin clinic is allergic dermatitis. Someone who is vulnerable to allergy could initiate allergic dermatitis because of contacting ultraviolet, fruit such as mango, pineapple.

Zhang Xiuying, associate chief physician of dermatology, holds that because of high temperature, high humidity and intense ultraviolet, we should avoid from basking between 10 am. and 3 pm. to prevent allergic dermatitis. If we have to expose to solar ultraviolet for a long time, we’d better wear long sleeve clothes, sunhat or use beach umbrella; apply sunscreen cream if going out even we have used beach umbrella or hat. Don not take or take few such fruits that may initiate allergy as mango or pineapple.

Additionally, reproductive capability of fungi is strengthened under sweltering weather. As a result, the number of patients who suffered athlete's foot, tinea manum, jock itch, sweat stain increases and their condition is also aggravated, especially the patients who suffered athlete's foot and jock itch. Thus we should clean our skin more frequently, maintain our skin dry and fresh, wear loose clothes which can absorb sweat to avoid mycetes sprout or aggravating infection. Also, we can apply prickly-heat powder on neck, axillary fossa, triangle of elbow to keep skin dry and fresh. Convergent driers and antimycotic drugs can be applied on those whose symptoms are severe.
