Prevention and Treatment for Heat Rash, Prickly Heat and Miliaria

The best prevention for heat rash, prickly heat and miliaria is to stay cool.

Heat rash also known as prickly heat and miliaria. Heat rash isn't something to be alarmed about. The rash usually goes away on its own. However, sometimes there are complications that need to be attended to by a doctor.

Sometimes heat rash may become infected with the sweat ducts get clogged with bacteria. We see this often with children. Sometimes parents can mistake the heat rash for diaper rash. When a baby has diaper rash it is because the skin is irritated. When the baby has heat rash that is infected, the symptoms manifest as pustules that are itchy and inflamed. Though it some times is hard to tell the different, diaper rash may only be redness and not bumps. If the child has the redness and pustules elsewhere on the body then it is heat rash for sure. Either way a doctor can determine which skin condition the baby has.

Miliaria profunda

People with milaria profunda can be suffering from heat exhaustion. If that be the case, people suffering from heat exhaustion may be experiencing nausea, dizziness, headache, low blood pressure, and rapid pulse. These symptoms occur because the sweat ducts are blocked and the moisture has no where to go to cool down the body. It is important to keep heat exhaustion in check; start by getting out of the heat. If left untreated it can lead to heatstroke which can be fatal. If you are exercising and these symptoms come on, stop exercising immediately If your are out in the sun try to get to a cool building or look for some shaded area to see if the symptoms subside.

Normally, the heat rash does go away on its own. If it lasts more than a few days you need to see your doctor or dermatologist who will check for other skin conditions. The typical questions you will ask your doctor is what caused the heat rash, what are the tests and treatment and how can I prevent it in the future.

The good thing is you will not need to undergo any tests, the doctor can see from the physical exam if you have a heat rash.

The best treatment is to get out of the heat and let your body cool down. Go into an air conditioned building or at least a room with a fan. Wear light clothing such as cotton that allows your skin to breathe. Do not exercise in hot humid weather and try to avoid hard physical work if you can. Stay out of the sun as much as you can. For mild heat rash no other treatment is necessary.

If your heat rash is more severe you may want to try some topical lotions such as calamine lotion for the itch. You can try Anhydrous lanolin to clear the sweat ducts, or topical steroids. Make sure the topical steroid is oil based. a water based lotion will only further clog ducts.

To prevent heat rash stay cool. Do not towel dry but let your skin air dry. Wear light clothes, avoid tight fitting clothes, stay out of the beating sun, try to remain in an air conditioned building or at least one with fans. Do not use lotions and creams, and do not exercise or over exert yourself. If you are outside stay in the shade. When you bath or shower use a nondrying soap that does not contain dyes or perfumes.

Well detailed information about prickly heat and other rashes so well explained. Promoted.

Great article. It's nasty when you get that. I've heard summer is as humid in the midwest as in a jungle because of all the corn that's planted.

Montreal is a humid city that is where I live, it is on the island of montreal. It has been 100 degrees here with the humity

Good work.

I didn't know the sweat ducts could become blocked... interesting article!

Returning with a well deserved vote up.
