Heat rashes, also known as prickly heat or miliaria, are tiny, red, bumpy spots that resemble small blisters on your skin. These skin infections affect the body during hot summers. These can occur anywhere on your skin, but the most common places are your neck, face, arms, hands, chest, thighs and back. These can cause itching and sometimes create a stinging or prickly sensation. This article gives you detailed information about prickly heat. Your questions such as, what causes heat rash, how to get rid of a heat rash, how to prevent yourself from getting a heat rash, and many more are answered here.
What Are The Symptoms Of Heat Rash?
Heat rashes are small; pinpoint; and clear to pink bumps spread all over the skin. These appear like gooseflesh or blisters. Infants usually are prone to heat rashes. However, adults also get them. There are three different types of heat rashes, which are:
- Clear heat rashes (Miliaria crystalline): These are the mildest form of heat rashes; these do not cause pain or itchiness.
- Red heat rashes (Miliaria rubra): These are placed deeply in the outer layer of the skin; and are usually red bumps with itchiness. These occur both in adults and in infants.
- Deep heat rashes: These are the rarest form of heat rashes. The deep heat rashes occur on your skin usually after repeated heat rash events. These lesions are flesh colored and are deeply placed on the outer skin layer.
Although anyone can get heat rashes, infants, young children, obese individuals, military troops, athletes, non-ambulatory patients, bedridden people, people who have decreased sweating, and people who have congenital absence of sweating are more prone to heat rashes.
How Are Heat Rashes Diagnosed?
In most of the cases of incidence of heat rashes, medical evaluation and formal diagnosis are not necessary. However, persistent presence of these rashes is diagnosed by examining the skin’s appearance, and by analyzing the patient’s recent history of exposure to heat. If the heat rashes seem quite resistant, a skin culture, or microscopic examination of samples may be required. In rare cases, skin biopsy may be required. Biopsy of the skin is the surgical removal of a very little portion of skin after numbing the region; and this portion is pathologically examined so as to find out if the rashes are caused by allergic reactions, bacterial infections, fungal infections, or eczema.
What Causes Heat Rash?
Heat rashes occur when the sweat glands in the skin are blocked and sweat is confined under the skin. This also is the reason for the irritation. This usually occurs in the summer when the weather is hot and humid, but there are also cases when people get heat rashes in the winter. People who tend to release more sweat, especially those are overweight are ones who are usually affected as their body parts that do not get enough exposure to air get overheated. Young children also are more prone to heat rashes. This is because their sweat glands are underdeveloped, which leads to the quick overheating of their skin, which in turn leads to the development of heat rashes.
What Is The Treatment Usually Given For Heat Rash?
A hydrocortisone cream is recommended by the doctors for treating severe heat rash. But these are steroid creams that can have an adverse effect on your skin by thinning it or even causing miliaria when used on a long term basis. Some other side effects of using this cream are nausea, headache, heartburn, dizziness, trouble sleeping, menstrual period changes, acne, or increased sweating.
What Are The Natural Treatments For Heat Rashes?
There are quite a lot of natural ways for treating heat rashes. These include
1. Herbal remedies
So, how to get rid of a heat rash using herbs? Numerous naturally occurring herbs can help in cooling your body and soothing your overheated skin. Some of these are discussed below:
- Chickweed: Chickweed is a lovely smelling herb native to Britain. This plant’s cooling and soothing properties serve as an excellent remedy for treating heat rashes. Those whose skin is hypersensitive to chemical fragrances or additives present in creams can use this herb for moisturizing, calming and cooling their skin. Extract its juice with the help of your wheatgrass juice extractor and apply it directly to the affected areas of your skin.
- Peppermint: Peppermint has a natural cooling effect on your skin. This is the reason why many artificial creams and lotions sold commercially have this herb in them in combination with chamomile- another herb with soothing and calming properties.

You can also drink a warm cup of peppermint while you rest yourself in your bathing tub for that extra cooling effect.
