Summer dermatitis, also known as summer dermatitis, is a common disease in the summer, due to the continuous high temperature and high humidity of the external environment, coupled with the skin sweating and not timely cleaning caused by the skin inflammation. Sweating is the main channel of heat dissipation and excretion of the body in summer, in hot days, human sweat can reach 3 to 4 liters per hour, and 99% of the water in sweat, the remaining 1%, half of the inorganic salts represented by sodium and potassium, half of the organic matter metabolized by urea, lactic acid and amino acids. These inorganic salts and organic substances are not substances that normally exist on the surface of the skin, when the water evaporates, these substances will remain on the skin, the amount of a lot, a long time, it will form an irritation to the skin, resulting in skin inflammation.
Summer dermatitis occurs in middle-aged, obese women, with typical symptoms occurring symmetrically on the extensor side of the extremities, especially on the front of the lower legs.

1, antibacterial drugs are not effective for simple summer dermatitis.
Some people like to use antibacterial drugs no matter what dermatitis they have. In fact, antibiotics, such as bleomycin, lincomycin and antifungals, such as imidazole in dacrynic acid and econazole in paregoric pine, do not play a role in improving simple summer dermatitis. Because even if there is a small amount of bacteria or fungus on the skin, but this is not the cause of summer dermatitis, and repeated exposure of the skin to some unrelated unwanted drugs, not only does not help the recovery of the disease, but can induce the occurrence of skin allergies.
2. You can’t apply sunscreen after applying ointment.
The ointment for the treatment of summer dermatitis cannot be applied to the same skin area at the same time as the sunscreen. If you want to cure the disease and prevent sun dermatitis, you can only use UV protection instead. This is because sunscreen is a chemical agent, frequent use can also cause allergic dermatitis and aggravate the symptoms of dermatitis.
3, the rest of the minerals should not be used for
The first time a summer dermatitis starts, the skin is itchy. The chemical name “Astemizole” is used to treat a variety of skin diseases and allergic rhinitis. In the last 10 years or so, clinical use has revealed that Xithromax can cause serious cardiotoxic reactions such as “tip-twisting ventricular tachycardia” and even death. For this reason, it was withdrawn from the market and discontinued in 1999. However, it is still available in China, but the dose of each tablet has been reduced from 10 mg to 3 mg, and the indication has been changed from 7 diseases to one, i.e. seasonal allergic rhinitis, so all skin diseases can no longer be taken.
4, wet compress therapy.
Wet compress is a common measure for topical treatment of acute summer dermatitis. Open wet compresses can evaporate water, take away the heat on the skin, so that the original dilated skin capillaries gradually retracted to a normal state. Wet dressing drugs should be used isotonic solution, such as 0, 9% sodium chloride solution, 3% boric acid solution. Wet dressing gauze can be 5-6 layers of sterilized gauze, each time according to the shape and size of the lesion cut, several sets of rotating use. Generally, the gauze can be washed and dried before use.
The correct method of wet dressing: soak 5-6 layers of gauze in the solution, so that it does not drip, but do not wring it out, stick it closely to the site of acute dermatitis, and change it every half hour. If the secretion of exudate, it is appropriate to change the wet dressing with gauze.
