Spring is the season of blooming flowers, all kinds of pollen will float in the air, and some allergic people will have skin allergy after inhalation. Now many office buildings are installed with central air conditioning, offices do not open windows for a long time to ventilate, and after the climate turns warm, some microorganisms such as mites that breed in air conditioners will float in the air, and some people will also suffer from allergies after inhalation. The ultraviolet rays of the sun gradually increase in spring, coupled with poor skin resistance in spring, but also susceptible to solar dermatitis, manifested as skin flaking, itching, dry pain and other symptoms, but also some manifestations of erythema, papules and scales, the people also called it “peach fungus”. As the weather warms up, people start to go outdoors, go for spring walks, enjoy nature, and at this time some small insects such as white lacewings, small midges, etc. also start to be active. These small insects burrow into people’s bodies and bite their skin, including their secretions on people’s bodies, can induce insect bite dermatitis, also known as papular urticaria. In addition to dermatitis, some allergic people are also prone to allergic rhinitis in spring, which manifests itself as constant sneezing, runny nose, watery eyes, and even chest congestion and asthma, also known as hay fever. Therefore, Director Zhang reminds people that while enjoying the infinite spring light, they should pay attention to prevent various allergies. People who have had solar dermatitis and seasonal dermatitis in the past should pay attention to avoid direct sunlight as much as possible and not to use alkaline cosmetics and soaps; in the season of blooming flowers, people with allergies should try to enjoy flowers less, and when they go out, they should bring masks and glasses to minimize the exposed parts, and they can also take some anti-allergy drugs in advance; when they go out in spring?$ play, to cuffs, trouser legs tied tightly to prevent small insects into; bedding, clothes, try not to sun in the tree under the sun, to dust when retrieved to dust off the small insects that may be on it; room, especially the installation of air conditioning room to often open the windows to keep the air fresh and circulating. If the above-mentioned allergic dermatitis occurs, do not go to the pharmacy to buy ointment without permission, because most of the topical drugs contain hormones, if used improperly, will form hormonal dermatitis, manifested as a short-term effect after using the drug, but after stopping the drug aggravated, long-term use of the formation of drug dependence, the skin becomes rough, atrophy, rash more serious, more difficult to treat, more difficult. She believes that patients should go to a regular hospital for patch allergy testing to clarify the cause of allergy and treat the symptoms under the guidance of a doctor. It is also beneficial to try to avoid allergens in life in the future.
