What is Heat Rash? Causes


Heat rash is a skin reaction to hot and humid weather that causes a prickly or itchy feeling. The medical name for heat rash is miliaria (pronounced: mill-ee-air-ee-uh). Heat rash usually happens when someone sweats a lot, such as in hot and humid weather, or while wearing heavy clothing. In most cases, heat rash goes away on its own after a few days.

The Different Stages of Heat Rash

There are three different stages of heat rash, each causing different symptoms:

1.Miliaria Rubra – The most common type of heat rash, this appears as clusters of small red bumps on the skin that can be itchy. Miliaria rubra is sometimes known as “prickly heat.”

2.Miliaria Crystallina – This type occurs when the sweat ducts become blocked close to the surface of the skin. This causes very fine clear blisters to form, which can be itchy or uncomfortable. Miliaria crystallina is also known as “sweat retention.”

3.Miliaria Profunda – This is least common and occurs when sweat ducts become blocked deeper in the layers of skin and cause bumps to form under the epidermis (the

Heat rash is a skin condition caused by sweat that does not evaporate from the skin. It can be uncomfortable, but it is not serious. The medical term for heat rash is miliaria.

Heat rash most commonly occurs in young babies and adults who are older than age 65. Adults who are overweight or have diabetes are also at risk of developing heat rash.

The condition usually goes away within days after you lower your body temperature and avoid getting overheated.

The rash usually develops in areas where clothing causes friction with the skin, such as under the arms or between the legs, but can develop anywhere on the body.

Heat rash or prickly heat is the inflammation of the skin caused by excessive sweating during hot humid weather. The fine sweat glands in the skin get clogged and cause a rash on the skin. Heat rashes are common in babies. They also occur in individuals who are overweight, have diabetes, or who wear tight clothing when it is hot.

Heat rashes usually clear up on their own within two to three days. However, some severe cases may need medical treatment. Here are some home remedies for heat rash:

1) Apply cornstarch powder – Cornstarch has been used to treat heat rashes for generations. It helps absorb the moisture from your skin and relieves itching and irritation of heat rashes. Talcum powder can also be used instead of cornstarch powder.

2) Use cold compress – Wrap a few ice cubes in a towel and apply it on the affected area to get relief from itching and irritation caused by heat rash. You can also use a package of frozen peas or corn instead of ice cubes if you don’t have them at home.

3) Keep cool – Try to keep your body cool to avoid sweating that could make your condition worse. You can take a cool shower, apply an ice pack on the affected area or

Heat rash (miliaria, prickly heat) is a skin disease marked by small and itchy rashes. The rashes are red and often appear in body folds. Heat rash is caused by blocked sweat ducts. The blockage causes the skin to retain sweat under the surface of the skin, resulting in inflammation. Heat rash usually occurs when you expose your skin to high temperatures for long periods of time.

Heat rash usually appears on areas of your body with sweat glands that become blocked. This includes your face, neck, armpits, groin, and chest. It can also appear in areas where skin rubs against each other or against clothing, such as between your toes or in your groin area. Although heat rash is most common during summer months, it can occur any time you sweat excessively and the weather is hot and humid.

Heat rash can affect people of all ages but is most common in infants and young children who may not be able to communicate that they’re uncomfortable or too hot. Infants are more susceptible to heat rash because their pores are smaller than an adult’s pores. This makes them more likely to become clogged due to excessive perspiration caused by overheating.

Heat rash is a skin irritation caused by excessive sweating. During hot, humid weather, the sweat glands in your skin may produce more sweat than evaporates or is absorbed, resulting in blocked pores and irritated skin.

The primary symptom of heat rash is an itchy or prickly feeling on the skin that may be painful or intensely irritating. You may also experience a stinging or burning sensation. The affected area of skin may appear red and feel warm to the touch.

Heat rash occurs most often in young children, although anyone can develop heat rash. It usually disappears within 2 to 3 days when you move to a cooler environment and avoid heavy exertion.

The rash causes red bumps that may look like pimples or blisters. They usually don’t hurt or itch; however, they can become irritated if anything rubs against them.

Heat rash usually goes away on its own within a few days after you cool off and stop sweating so much. In the meantime, there are things you can do to relieve discomfort:

• Stay cool — take frequent cool baths or showers.

• Wear loose-fitting clothing so air can circulate through your clothes and help cool you off.

• Do not use talcum powder, creams or ointments that contain petroleum jelly (Vaseline). These products tend to block the sweat glands even more.

• If the rash persists for longer than a week or worsens at any time, see your doctor for advice.”
