The Four Types of Heat Rash

The four types of heat rash (miliaria) are named by the way they look on the skin (visual characteristics) and are discussed on the following:

Clear (miliaria cystallina)
Red (miliaria rubra)
White/Yellow (miliaria pustulosa)
Deep (miliaria profunda)

Heat rash usually appears as very small pinpoint bumps at the entrances to sweat glands. In some areas, there may be red or pink patches of skin. More advanced heat rash may have greater degrees of irritation and large welts, and raised red bumps. Some people with heat rash are very itchy while others may have no irritating symptoms.

Any body part with sweat glands may be affected. Characteristic heat rash areas include the:

Face
Neck
Back
Abdomen
Groin
Under the breasts
Elbow folds
Buttocks

Clear (Miliaria Crystallina)

Red (Miliaria Rubra)

White/Yellow (Miliaria Pustulosa)

Deep (Miliaria Profunda)

Miliaria is the medical term for the heat-related skin condition where tiny, pinpoint, and pink to clear bumps form over a body area like the face or neck. It is caused when small sweat droplets are trapped in the skin due to blocked pores. This trapping of sweat may cause inflammation and itching around the sweat pores. Miliaria is very common in infants but may also occur in adults. This condition occurs especially after repeated episodes of sweating in a hot, humid environment. Miliaria may look like small clear blisters or like gooseflesh.

There are three common types of miliaria:

Clear (miliaria crystallina): mildest form, usually the blisters aren't itchy or painful
Red (miliaria rubra): occurring deeper in the outer skin layer, itchy with red bumps, prickly heat found in infants and adults;
White/Yellow (Miliaria Pustulosa): When pustules form on a case of red heat rash it is called white/yellow heat rash (miliaria pustulosa). These pustules may be the first signs of a skin infection,
Deep (miliaria profunda): least common form, usual adults after repeated events of heat rash, flesh-colored lesions.

What Causes Heat Rash?

Heat rash, or prickly heat, is thought to arise from plugging of sweat ducts and hair follicles on the skin. Occluded sweat glands with trapped sweat give rise to the tiny water bumps seen in this condition. Human sweat (with its high salt content) is a very potent skin irritant and may cause skin rashes. It is important to wash off sweat with gentle soap and water.

What Are the Risks for Heat Rash?

Anyone can develop heat rash, especially when in certain environments. Some individuals are more prone to heat rash including:

Babies (infants)
Children under age 4
Athletes or people who exercise in hot environments
Obese or overweight persons
Bedridden and non-ambulatory patients
Individuals with congenital absence or decreased sweating
Military troops

What Procedures and Tests Diagnose the Cause of Heat Rash?

Most people with a heat rash it usually goes away seeing your doctor.

Persistent heat rash is typically diagnosed from the characteristic skin appearance on the exam and a history of recent heat exposure.

Atypical or more resistant cases of heat rash may require skin culture, a microscopic exam from skin scrapings, or less commonly a skin biopsy (surgically removing a very small piece of skin using a local numbing agen. This skin is sent to a pathologist for closer examination.

Additional tests may be required to exclude other causes of skin rashes, for example:

Bacterial infections.
Allergic reactions.
Eczema.
Fungal infections.

10 Home Remedies to Relieve Pain and Other Symptoms of Heat Rash

Home remedies for treating heat rash include washing the affected area with a mild soap and rinsing the area, then gently dry the area. Wear clothing that allows the skin to breathe in a hot environment. Stay hydrated and drink plenty of water to prevent dehydration in hot environments. Medical care may be necessary if the heat rash does not resolve with home remedies.

Most heat rash resolves without treatment, often within a day after changing to a cooler environment. The best way to prevent heat rash is to avoid sweating by staying in cooler areas, using fans, and limiting physical activity.

The following self-care steps and remedies may help with heat rash.

First aid

The first step in treating heat rash is to wash the affected area with a gentle soap (for example, Dove non-soap cleanser or something similar). Next, rinse the area with water and gently pat dry with a towel. It is recommended to wash several times a day, especially after exercise, prolonged walking, or heat exposure.

Remain in a cool environment and allow for adequate ventilation of the skin.
Take cool showers or baths
Rest in an air-conditioned room at 70 F to 72 F (21 C to 22 C) is therapeutic. If no air conditioning is available at home, safe retreats include indoor shopping malls, grocery stores, movie theaters, hotel lobbies, ice-skating rinks, bowling alleys, etc.
Avoid skin-to-skin contact by placing a clean cotton washcloth or material between skin folds like under the breasts or abdomen.
Apply cool packs over the affected areas (do not leave packs on longer than 20 minutes per hour).
Mild cortisone creams like hydrocortisone (Cortaid) or prescription cortisone creams like triamcinolone (Triesence, Trivaris Intravitreal) may be helpful for resistant rashes or resulting eczema. If it is necessary, apply these creams twice daily. For large areas, you should contact your healthcare professional.
Oral antihistamines, such as diphenhydramine (Benadryl), can help decrease itching, mostly through the sedation associated with these medications.

Clothing and Heat Rash

Getting naked may keep the body cooler but it does not avoid the problem of sweat buildup especially under the breasts, abdomen fold, between buttock folds, and places where skin overhangs. It may be best to wear light, cotton, absorbent fabrics that separate out skin fold areas. Individuals who do not wear underwear usually notice more retained sweat and therefore more irritation in areas between the buttocks and groin. Short sleeves tops and shorts are often helpful.

Drinking Water

Drink plenty of water for overall hydration.
Water can help maintain cooler body temperatures.
Dehydration may lead to weakness and generalized malaise.

What Factors Aggravate Heat Rash?

High humidity
High temperatures
Jacuzzi's, saunas, and steam rooms
Fever
Sunburn
Regular sweating or hyperhidrosis (excess sweating)
Tight garments and non-breathable fabrics

What Are the Complications of Heat Rash?

While heat rash does not lead to heat stroke, both conditions may rarely occur in the same individual. Heat rash is a very common, self-limited skin condition while heat stroke is an uncommon more serious, generalized illness. Heat stroke requires immediate medical attention. Heat stroke is particularly life-threatening in the frail, ill, and elderly.

Ringworm is caused by a fungus. See Answer

What Conditions Mimic Heat Rash?

Many other rashes can look like heat rash. Some of these other conditions include:

Folliculitis (a bacterial infection of the skin commonly with "staph")
Acne
Eczema
Allergic Rash
Medication reaction or drug eruption
Grover's disease (also called transient acantholytic dermatosis) causes itchy bumps on the abdomen and chest that worsen with heat)
Niacin medication (in some individuals, cause a temporary overall body flushing and heat rash like appearance that improves in a few hours)

When Should You Call a Doctor for Heat Rash?

If the rash is not improving or resolving with the home treatment described or becomes worse after several days, the patient should see a physician be sure there is not a bacterial infection or other cause for the rash. If the rash is accompanied by other significant symptoms (dizziness, chest pain, shortness of breath etc.) the person should seek medical care.

Seek medical care immediately if you have a heat rash with these symptoms and signs.

Fever.
Headaches.
Nausea.
Dizziness.
Vomiting.

Can Heat Rash be Prevented?

How to Prevent Heat Rash

Move to cooler environments, for example:
Air coinditioning or oscillating fans.
Limit your physical activity in a hot environment.
Wear cool breathable fabrics such as cotton.
Avoid polyester and nylon clothing.
Maintain a comfortable room temperature with fans and air conditioning.
Babies and infants should be kept comfortably cool and dry. Because of babies' and infants increased fat folds and diaper irritation, they frequently get rashes on their diaper area and abdomen folds (diaper rash).
Infant drooling may cause further occlusion of sweat ducts and hair follicles leading to heat rash on the face cheeks.
Bedridden and wheelchair-bound people should be rotated and moved to avoid constant sweating and occlusion in the same area.

Heat Rash Do's

Get out of the heat.
Wear cool, breathable fabrics, for examiple, cotton.
Maintain comfortable temperatures with fans and air conditioning.
Wash off the skin with mild soap and pat dry after sweating or exercise.
Take a cool shower or bath.

Heat Rash Don'ts

Don't wear polyester and nylon fabrics in the summer.
Don't cover with ointments, Vaseline, or heavy creams.
Don't scrub or rub the skin to remove heat rash bumps.
Don't stay in the heat or humidity.
Don't go in a hot tub, sauna, or Jacuzzi.
