Heat rash is small red rashes that may itch or cause an intense "pins and needles" feeling. It happens when the sweat gland ducts get clogged due to bacteria and/or dead skin cells. The trapped sweat causes an itching, irritation and the rash of tiny red blisters. It is most common in babies. Heat rash can impact the face, neck, under breasts or scrotum, skin folds, areas that rub against clothing like the chest and stomach, groin, and elbow creases. Most people get heat rash when they do activities that cause you to sweat a lot, spend too long in hot humid weather, or wear heavy clothing that rubs. It will usually go away in a couple of days, but in some severe cases it can last for several weeks and can cause serious disability. If not taken care of, heat rash can get irritated and cause a secondary skin infection.
Q1: In your paragraph, you say that it can last several weeks and cause serious disability; what kind of disabilites?(M.Seibert)
A: If it gets bad enough, it can be very painful to walk or move the limbs causing the person to be on bed rest.

Q2: Is there any reason why heat rash is most common in babies? (S. Hardewig)
A: Because they become overheated easily or they are overdressed. Babies are also prone to sicknesses and they can get heat rash from having a fever.

Q3: Can heat rash be treated, if so then how? (P. Melton)
A:Heat rash can be treated with creams such as Calamine Lotion, Menthol/Camphor based preparations, or topical steriod creams. Dont use oil based preparations because they can clog sweat glands and make the heat rash worse.

Q4: Is there a certain race that heat rash affects more than others? Or does it not matter? (A. Jones)
A: There isn't a certain race that is more affected. This is because heat rash is caused from overheation and clogged sweat glands and since every race overheats and has sweat glands, we are all capable of getting it.

Q5: If its not taken care of, what is the secondary skin infection? (C.Muth)
A: The secondary skin infection would just be swelling, pain, redness, and warmth around the rash. It could also have red streaks extending from the rash area. There would usually be a discharge of pus.
