Symptoms of summer dermatitis

Summer dermatitis is more common in middle-aged obese women. Its typical symptoms are symmetrical occurrence on the extensor side of the limbs, especially in front of the lower legs. Initially, it is a dense corn-sized erythema, papules or papule blisters, with obvious itching and a burning sensation. Due to the unbearable itching, people scratch, often leaving multiple strip-shaped scratches and blood scabs, which will leave pigmentation after the itching subsides.

Causes of summer dermatitis

Sweating is the main channel for the body to dissipate heat and excrete in the summer. On hot days, the body can sweat 3 to 4 liters per hour, and water accounts for 99% of the sweat. Of the remaining 1%, half is inorganic salts represented by sodium and potassium, and the other half is organic matter from urea, lactic acid, and amino acid metabolism. These inorganic salts and organic matter are not substances that normally exist on the surface of the skin. After the water evaporates, they will remain on the skin. If the amount is large and the time is long, it will irritate the skin and cause skin inflammation.

What to do with summer dermatitis

First of all, we should pay attention to heatstroke prevention and cooling. In a particularly humid and hot environment, the skin is prone to poor perspiration, and poor heat dissipation in the body will cause skin diseases. Secondly, eat less spicy and irritating things, and eat more cool foods such as vegetables and fruits. In addition, we must keep the skin clean. When taking a bath every day, you can use some bath lotions containing Chinese medicine ingredients and bactericidal effects. Once mild dermatitis and heat rash appear, dry the skin after taking a bath, and apply some talcum powder, which usually subsides on its own. If the situation is more serious, you can use some "Ten Drops of Water" to drip into the bath lotion, which will also have a bactericidal and cleansing effect. If the situation still does not improve, you need to go to the hospital for a dermatologist for diagnosis and treatment.

Precautions for summer dermatitis

Daily precautions

(1) Avoid wearing clothes that are not breathable. It is best to wear clothes made of all-natural materials such as cotton, linen or silk.

(2) Wash the affected area frequently with warm to cool water. Avoid using hot water to relieve itching.

(3) In summer, you should drink more water instead of sugary drinks. Drinking more water can dilute the concentration of chemical components in sweat.

(4) In hot weather, stay in cool and ventilated places as much as possible and avoid going out frequently. When going out, it is best to use a black parasol to block the sun, whether it is cloudy or sunny, because black can absorb ultraviolet rays of various wavelengths to prevent ultraviolet rays from damaging the skin.

(5) In hot and humid seasons, you can use air conditioning to dehumidify to prevent excessive sweating.

Precautions for medication

(1) When purchasing OTC topical medications at a pharmacy, you must read the drug instructions in detail before use.

(2) Avoid using drugs that have caused allergic reactions when taken orally, injected, or applied topically.

(3) If an allergic reaction or irritation occurs during the use of topical medications, discontinue use immediately.

(4) If the topical preparations of the same drug have multiple concentrations, a low concentration should be used first, and then the drug concentration should be gradually increased based on the therapeutic effect.

(5) Choose different drugs according to the patient's gender, age, and site of disease. For children or women's faces and skin folds, it is advisable to choose non-irritating and highly safe topical preparations.

(6) The area to which topical medications are applied at one time should not be too large. If the area of ​​skin lesions is large, the medication can be applied in turns over several times.

If the symptoms are not relieved after 3 to 5 days of using the above-mentioned drugs or secondary bacterial infection occurs, skin damage or severe itching occurs, the patient should seek medical attention in time to avoid delaying the disease and damaging health.
