Also because the lesion performance is fine flaking so also called “simple furfuraceous rash”. This discoloration is not related to roundworm. Although it is called “ringworm”, it is actually a different thing from the medical term ringworm, which is a superficial fungal disease of the skin. Why does spring dermatitis occur? Because spring is the time when people’s skin metabolism is active and secretions from sebaceous glands and sweat glands increase, they are prone to allergic reactions when exposed to various allergens. Spring is a good time for pollen, bacteria, viruses and other allergens to multiply and spread, and these things flutter with the wind and fall on people who go out for a walk, which can easily cause allergic dermatitis and rashes; the UV content of the sun is the lowest in winter, but the UV content rises suddenly when spring comes, and people have difficulty adapting to it. Once exposed to strong UV radiation, it can cause skin damage and dermatitis. At the same time, spring is the peak season to go out and travel, if you do not pay attention to sun protection, will aggravate or induce dermatitis. It has been determined that about 30% of the population is allergic to UV rays, of which the human body has the highest sensitivity to UV rays in spring; people who work indoors are more sensitive to UV rays than those who work outdoors; young people are more sensitive than young children and the elderly. Therefore, spring dermatitis is more likely to occur in young adults and indoor workers.
