Use cool material clothes, avoid wearing wet clothes, drink plenty of water, cool the rash area … to help reduce itching and discomfort caused by heat rash.
Doctor Dinh Ngoc Lien, Dermatology – Aesthetic Skin Unit, Nguyen Tri Phuong Hospital, said that heat rash (a form of heat rash) is a common disease in summer, in hot and humid climates. It occurs when sweat does not escape to the surface of the skin, due to blockage of sweat glands in the deeper layers of the skin. This condition can lead to inflammation, redness and blisters, accompanied by itching or stinging, mild swelling; more severe than bacterial superinfection.
People who are overweight and obese, people who sweat easily are prone to heat rash. In addition, babies and children are also “delicious” of heat rash, because their sweat glands are still in the developing stage. Areas that sweat a lot, such as the face, neck, lower chest, scrotum, etc., and areas with lots of skin folds or areas that rub against clothing (back, chest, abdomen) are most likely to develop a rash.
According to Dr. Lien, heat rash is not dangerous, usually disappears on its own within 24 hours. Tips to avoid recurrent heat rash and reduce itching symptoms is to limit exposure to hot and humid environments. Dress your child in light, loose cotton clothes, clean bedding, and help absorb sweat. Gently exfoliate to remove dead skin cells and sebum that can clog sweat glands.
When exercising, you should choose a place and time with a cool temperature, low humidity, to help your body reduce sweat. At the same time, use fans and air conditioners to reduce body temperature. Taking regular cool showers and patting your skin dry will help keep your skin comfortable. You also need to avoid wearing wet clothes, such as after swimming.
In the event of a skin rash, apply a cool compress, or damp cloth, or ice pack wrapped in a towel to the affected area for up to 20 minutes at a time. If itches, pat the rash instead of scratching. Drink plenty of fluids to prevent dehydration.
In addition, in the case of persistent heat rash, many patients can use some over-the-counter topical products such as calamine, menthol, cream or ointment containing camphor. People over 10 years old can use steroid creams that will help reduce itching and inflammation. Other antibacterial products can help control or prevent infection.
if you have a rash that persists or gets worse, such as fever, enlarged lymph nodes, muscle pain; signs of infection (broken blisters or pustular lesions), heat exhaustion and inability to sweat… need to see a doctor for a diagnosis to find the cause. Many diseases that cause rashes, such as measles, chickenpox, folliculitis, acute HIV… can be confused with heat rash, Lien recommended.
