Incentives: pustules, commonly known as yellow water sores, mostly occur in summer and autumn with high temperature and humidity. They are the most easily acquired skin diseases in hot summer, especially among children, and can spread to each other through contact. It is an acute purulent dermatosis caused by Staphylococcus aureus or hemolytic streptococcus, which can be divided into bullous pustulosis and pustular pustulosis.
Symptoms: Pustules mostly occur in exposed parts such as face and limbs.

light injury
Reason: Sunburn dermatitis, also known as sunburn or sunburn, is a photosensitive skin disease and an acute inflammatory reaction after normal skin exposure. In summer, the content of ultraviolet rays in sunlight suddenly increases, and the sensitivity of human body to ultraviolet rays also increases. Under the action of ultraviolet rays, epidermal cells are destroyed, protein degenerates and decomposes, and capillaries dilate and congest, leading to dermatitis. This disease is more common in late spring and early summer, especially in children, women, skiers and ground workers. The intensity of its reaction is related to light intensity, irradiation time, individual skin color, physique, race and other factors.
Symptoms: Skin erythema appears on the exposed parts such as face, neck and back of hand, especially on the forehead and cheeks, with papules and slight desquamation the size of millet, which are aggravated after sun exposure, even swelling and blisters, often causing unbearable pain, and the symptoms are aggravated at night, which will cause infection after scratching. It takes 2 ~ 3 days to recover, and it takes about a week to recover. Individual patients may be accompanied by conjunctival congestion and eyelid edema. Those who are exposed to the sun for a long time can cause systemic symptoms, such as fever, chills, headache, fatigue, nausea and general malaise.
Prevention: First, try to avoid the sun. Especially for patients who have suffered from this dermatitis, they should apply sunscreen above SPF 15, and those with severe photosensitivity should apply sunscreen above SPF30 to protect their skin from strong sunlight stimulation. Second, every morning 10 to 2 pm, the sun's ultraviolet rays are the most, so we should try to reduce going out during this time. If you have to go outdoors
Wear loose long-sleeved underwear, a sun hat and a parasol for protection. Third, people who are sensitive to light, after ingesting light-sensitive substances, such as certain foods and medicines, or being exposed to the sun for a long time, will also have symptoms of solar dermatitis in the exposed parts of the skin, so these stimulating factors should be avoided. Once the symptoms of solar dermatitis appear, don't take a bath with hot water immediately, so as not to aggravate the symptoms of dermatitis, and don't scratch it with your hands, because once scratched, it is easy to get infected. Under the guidance of a doctor, ointment for relieving itching and pain can be applied to the affected area. In addition, although lupus erythematosus and freckles are not photosensitive skin diseases, sunlight will also aggravate the condition.
Mite dermatitis
Incentives: Many people are infected with acaroid dermatitis in summer, mostly because the mat just laid at home is not disinfected. Symptoms: Acaroid dermatitis mostly occurs in the skin of human neck, chest, abdomen, back and limbs, and it is mostly edematous bright red macula, which is often itchy and unbearable.
Prevention: To avoid acaroid dermatitis, we must first find the cause, find out the root cause of acaroid dermatitis, and eliminate it, otherwise even a large number of drugs can not be cured. For newly-bought or long-standing sleeping mats, mites must be removed and disinfected before use. Generally speaking, it can be scalded with boiling water, or sprayed with pesticides, and then exposed to the sun. Mites are afraid of light, high temperature and dryness. Therefore, in summer, they should always clean the room, remove sundries, keep the room ventilated and dry, and at the same time strengthen personal protection, take a bath and change clothes frequently, and dry more bedding and clothes. In addition, people who keep pets at home should also pay attention to the fact that cats and dogs are easy to parasitize mites, and they should be sterilized frequently to avoid family members, especially children, from suffering from acaroid dermatitis.
