Summer is a high season for skin diseases. The main changes in the summer climate are characterized by increased ultraviolet radiation, rising temperatures and humidity, as well as the proliferation of various insects. Many skin diseases are easily induced. Especially in Guangdong, the summer is especially long and hot and humid, and various summer-prone skin diseases will also come as expected, for this reason, the following summary, I hope you know about various summer-prone skin diseases early, early prevention. A, sweat disorder class of skin disease in the hot weather, skin “breathing” difficulties, sweat excretion is not smooth, so the skin disease accumulation in the skin formed, such as prickly heat, sweat sore rash, sweat gland cysts. Prickly heat is common. Prickly heat: It is caused by the high temperature and humidity in the environment, excessive sweating, which cannot evaporate in time, resulting in the blockage of sweat holes and the accumulation or rupture of sweat, some manifest as small rice-grain-sized superficial blisters, which are easily broken, lightly flaking and healed, mostly in infants and pregnant women, called white prickly heat; some are scattered red papules, but not related to hair follicles, called red prickly heat, mostly in children, and some are small pustules, called pustular prickly heat. Some of them are small pustules called prickly heat. To prevent the occurrence of prickly heat, we should pay attention to the ventilation and cooling of the indoor environment to avoid excessive humidity and high temperature; dress generously to reduce sweating and facilitate the evaporation of sweat, and change clothes regularly; try to keep the skin dry, wipe sweat with a dry towel, obese people, infants and mothers should take a bath regularly, but do not use cold water, wipe dry and put on prickly heat powder. Treatment can be done with cool, astringent and antipruritic drugs. If pustular prickly heat occurs, you should go to the hospital for comprehensive treatment. This is caused by the body’s strong reaction to the sunlight, mostly seen in fair-skinned people. In addition, although lupus erythematosus and freckles do not belong to photosensitive skin diseases, they may be aggravated by sunlight exposure. The main prevention of photosensitive skin diseases is to avoid photosensitive substances and direct sunlight exposure. The common ones include sunburn and photosensitive dermatitis. 1, sunburn: due to sudden excessive sun exposure, manifested as 3-6 hours after sun exposure in the sun site erythema, in serious cases can form blisters, there is obvious burning pain, may have general discomfort. The prevention of sunburn should first avoid exposure to strong sunlight, and should be gradual, gradually increasing the amount of exposure. Treatment is generally symptomatic, can be topical protective agents such as a variety of emollients, furnace glycolic lotion, corticosteroid creams. 2, photosensitive dermatitis: photosensitive dermatitis is due to some people are allergic to ultraviolet light, only seen in a small number of people, these people usually 1-2 days after the onset of sun exposure, the rash is mostly on the face, neck and neck “V” shaped area, the back of the hands and upper limbs, manifested as small papules, small blisters, conscious itching. In severe cases, the rash can also appear on non-lighted areas, without pain, itching is obvious and disappears very slowly. If not actively treated, chronic photosensitive skin disease may develop. Because the attack of this disease is related to allergies, so we should pay attention to the protection of light, from 9:00 to 5:00 p.m. every day it is best not to go out, when you have to go out to do a good job of sun protection measures, once the rash occurs, you can use a variety of ointments or creams containing hormones, but also consult a doctor to choose a suitable oral class of drugs. Third, microbial infections skin diseases sweat impregnated skin, dust adhesion, easy to attract viral, bacterial and fungal infections. 1, viral skin diseases: there are chickenpox, rubella, etc.. Chickenpox starts more rapidly, with fever, lethargy, loss of appetite and other systemic symptoms, children are the high incidence of chickenpox. Rubella is an acute infectious disease caused by the rubella virus that is transmitted through the respiratory tract, and symptoms appear after an incubation period of 2 to 3 weeks after inhaling the virus. To prevent viral skin disease, take your child to public places less often, and if your child has chicken pox, the fever period in the diet should be light and easy to digest, pay attention to rest. You should also keep the skin clean and hygienic, and apply some anti-itch drops when the skin itches. The key to preventing rubella virus is to reduce contact with rubella patients. 2. Bacterial skin diseases: common ones are folliculitis and impetigo. On the one hand, because of humidity, on the other hand, because the human skin itself has a lot of conditional pathogenic bacteria, encountering hot and humid climate is particularly easy to reproduce. Combined with the blockage of hair follicle sebaceous glands and secondary infection, the result is folliculitis. The prevention method is to bathe and change clothes regularly to avoid sweat stains and bacterial infections and keep the skin clean. 3. Fungal skin diseases: common ones are tinea pedis, ringworm and lichen planus. These are skin diseases caused by fungal infections and are often aggravated in the summer because of the fungal preference for warmth and humidity. Tinea pedis manifests as peeling, macerated vesicles between the toes or a majority of blisters on the lateral edge of the foot, which may or may not be itchy, and the rash may gradually expand outward if left untreated. Tinea cruris presents as a ring-shaped erythematous desquamation of the inner thighs and buttock fissures that is eccentrically enlarged, often surrounded by small papules, and is self-induced itching or pain. Tinea pedis manifests as a pattern of florid skin changes. Both tinea pedis, ringworm and lichen planus are contagious, so you should avoid sharing hygiene utensils such as towels and slippers, and change your shoes and socks and underwear regularly. Insect dermatoses In summer, when the temperature is high and there are many mosquitoes and insects, the skin is most likely to be attacked by the bites of various poisonous insects. There are common insect bite dermatitis and cryptomeria dermatitis. 1, papular urticaria, also known as insect bite dermatitis: the disease is related to mosquito bites, such as bedbugs, fleas, lice, mites, mosquitoes and other insect bites on the skin after the injection of saliva, induced allergic reactions. The rash is green beans to peanuts slightly fusiform red windbag-like damage, often with small blisters at the top, some hemispherical elevation of large tense blisters, the rash is mostly found on the trunk, limbs, can be in patches or scattered, itching is obvious. Prevention of this disease as little as possible to the grass, shade or damp, mosquito places, indoor mosquito incense, do not sleep on a straw mat cooler, after the rash can be used externally with a variety of ointments or creams containing hormones or choose the appropriate oral medication. But it should be noted that it is best not to use safflower oil and other smears, because this may lead to allergies, but aggravate the condition. 2, cryptoptera dermatitis: this is a relatively special summer skin disease, when the cryptoptera attached to human skin, after being patted or crushed, the venom in its body will adhere to the skin to produce damage, causing cryptoptera dermatitis, redness, swelling, pus, etc.. Suggestions: People with sensitive skin should avoid places where trees are abundant, and outdoor activities should be well protected from toxic insect bites. Found that there are mosquito bites on the skin, should avoid directly on the torso pat insects, contact areas should be washed with soap and water as soon as possible.
