Heat Rash Symptoms, Treatment, and Prevention

What is heat rash?

Heat rash is a skin irritation that stings and makes your skin red. It is also called miliaria or prickly heat. If you have heat rash, your skin may feel itchy. Small bumps may form, and you may feel some “prickly,” tingling pain.

Heat rash occurs most often in hot, humid weather. Anyone can get heat rash. It is most common in infants and young children.

Symptoms of heat rash

Heat rash usually looks like a cluster of pimples or small blisters. It is most likely to appear in places where skin touches skin, including:

• Neck
• Groin
• Underneath the breasts
• In the creases of the elbows
• Armpits

What causes heat rash?

Heat rash happens when you sweat too much. The sweat gets trapped under your skin and blocks your sweat glands. If your pores cannot clear out the sweat, you may get a rash.

Heat rash often happens when it is hot and humid outside. Having a high body temperature, being overdressed, or being in a hot environment can also cause it. Babies who are bundled in too much clothing are most likely to get heat rash. People who are not used to hot weather may also get it more easily.

How is heat rash diagnosed?

There are no tests for heat rash. Your doctor can diagnose it just by looking at it. But most cases don’t need to be seen by a doctor. They go away by themselves. If your heat rash doesn’t go away after 3 or 4 days, or if it seems to be getting worse, call your doctor. In some cases, heat rash may be caused by an infection.

See your doctor if your itchiness is severe or if the rash area swells or oozes pus. If you feel dizzy, nauseated, confused, or you have trouble breathing, go to the emergency room right away. These symptoms can be signs of serious heat-related illnesses, such as heat exhaustion or heatstroke.

Can heat rash be prevented or avoided?

In many cases, heat rash can be avoided. In hot weather, dress yourself or your child in lightweight cotton clothing. Cotton helps absorb moisture to keep it off of your skin. If the weather is hot, turn on the air conditioner, or use a fan to help you stay cool and dry.

Heat rash treatment

The most effective treatment for heat rash is to keep your skin cool and dry.

• Cool down. Avoid hot and humid places. If possible, stay in air-conditioned areas, or use fans to circulate the air. Use cool compresses to bring down the temperature of the affected skin.
• Dry off. Keep the irritated skin dry. Use a fan to dry the skin off faster and to reduce sweating.
• Reduce friction. Wear loose clothes to prevent irritation caused by clothing that rubs against the skin.

If your rash is severe, your doctor may prescribe a lotion to help relieve your pain or discomfort. Avoid using baby powders, ointments and creams at home. They can block pores even more.

Living with heat rash

Whether you are trying to treat heat rash or prevent it, the best way to live with it is to keep the skin cool and dry. Avoid overdressing and tight-fitting clothes. Try to stay out of hot, humid conditions. Keep your sleeping area cool and allow air to circulate.

Questions to ask your doctor

• What caused my heat rash?
• Is there a treatment that will help?
• What can I do at home to make myself more comfortable?
• Should I let my baby go without a diaper to help clear up the heat rash?
• Should I use diaper ointment on my child?
• Should I stop exercising until the heat rash clears up?
• What is the best way to prevent heat rash?

Heat Rash Treatment and Prevention

With warmer weather upon us, you’re probably itching to get outside and we don’t blame you. But with heat and sunlight come more risk for heat rash and other ailments, like sunburn, dehydration heat cramps, heat exhaustion, heat stroke, and allergy exacerbations.

You may be especially susceptible if you’re engaged in intense physical activity that makes you sweat. To prevent injury or heat rash, it’s important you take precautions to protect yourself and your family. 

How can you be sure your rash is in fact a heat rash? And, if it is, what’s the fastest way to get rid of it? Let’s take a look.

Heat Rash Treatment

Wondering how to treat heat rash? The best method will depend on what area of your body is affected.

Most cases of heat rash will resolve on their own within a few days. However, there are some things you can do at home to help alleviate a visible rash. 

For instance, if your rash is itchy, you can apply an over-the-counter anti-itch cream to small spots, like hydrocortisone. This may be especially helpful in areas like the underarm, behind the knee, or in skin creases that get more irritated. Applying Aloe vera topically is another well-known remedy for skin rashes.

A cool bath or shower may help with all-over itchiness, or you can apply a cool compress to a particularly itchy area. If you lay in the bathtub for a while, consider adding colloidal oatmeal as this has been shown to help calm irritated skin.

Additionally, lower the temperature of your environment whenever possible, by doing things like keeping the air conditioning on or turning on an extra fan in your bedroom. Wear loose-fitting clothes that don’t stick to sweat and further trap heat against your skin.

To treat heat rash also means not making an existing rash worse by irritating it further. Don’t scratch too hard or pick at blisters as this makes them stick around longer. As your rash begins to heal, you can use a moisturizing lotion to help calm the skin. 

What Does Heat Rash Look Like?

Given that your skin is the largest organ in your body, it’s not surprising that many different skin rashes exist. Heat rashes (also known as miliaria) are one of the most common types of rashes, affecting both children and adults.

They form when your sweat glands become clogged and can’t expel sweat, thus trapping perspiration under your skin. They are most commonly experienced among people who live in humid, hot climates and individuals who sweat frequently.

Heat rashes usually appear in skin folds or areas where clothes cause friction. For children, this is often in the neck, shoulders, or chest areas, whereas adults more typically develop heat rashes in the armpits, elbow creases, and groin.

They can appear several hours or even a few days following sun exposure. The rash can look differently depending on skin type, but generally, it will have some of these similar characteristics:

• Raised or rough areas on the skin
• Red patches that are itchy
• Clusters of small bumps or blisters that have a halo around them
• Areas of the skin that feel like they’re burning

A heat rash most often appears in areas like underneath the breasts or scrotum, around the groin, in folds of the skin like elbow creases, elbows, or behind the knee, and on the neck, back, legs, arms, and chest.  

4 Types of Heat Rash

If you’re looking for a sure sign of how to identify a heat rash, unfortunately, there isn’t one. That’s because there are different types of heat rashes, which range in severity from superficial blisters to deep, red lesions.

To determine what type of rash you might have, be on the lookout for the following adult heat rash signs and symptoms.

1. Miliaria Crystallina

Miliaria crystallina is the mildest form and affects the sweat ducts on the epidermis or top layer of skin. If you have miliaria crystallina, you’ll notice small clear or white bumps filled with fluid that can easily break. Despite popular belief, this type doesn’t itch and shouldn’t cause discomfort. It’s also most common in babies.

2. “Prickly” heat rash

This rash is also called Miliaria rubra and is known to be more painful than miliaria crystallina because it occurs deeper within the epidermis. This type causes red bumps, an itchy or prickly sensation, and a decreased amount of sweat in the affected area. It can also result in inflammation and soreness of the skin since the body can’t release sweat through the skin’s surface. It’s more common in adults than in babies and children.

3. Miliaria pustulosa

Miliaria pustulosa is similar to miliaria rubra, except the red bumps associated with the heat rash fill with pus, forming lesions and causing them to become inflamed and pustular, or pus-filled.

4. Miliaria profunda

Miliaria profunda is the least common form and affects the dermis or a deeper layer of skin below the epidermis. Sweat from your sweat glands is retained in your skin, forming larger, flesh-colored bumps. This type usually occurs in adults after a long period of physical activity and can reoccur or become chronic.

Baby Heat Rash Treatment

Adult heat rash is different than baby heat rash. Some at-home remedies for babies include using thin cotton bedding and loose-fitting clothing, cooling the home with air conditioning or fans, and taking cool baths with no soap to help reduce the baby’s high temperature. Try using cool compresses for irritated areas of the skin, and not using creams or oils on the baby’s skin. 

Be sure your baby is drinking enough fluids to stay hydrated, let any excess moisture on their skin air dry, and wipe off any lotions or creams that have been used.

How to get rid of heat rash quickly?

The best way to get rid of a heat rash quickly is to ensure the affected area is kept cool and dry. Avoiding exposure to the heat that caused your rash can expedite healing as well.

It is important to note that taking a warm or hot shower will make the symptoms worse!

If you’re experiencing prickliness or itching, creams like calamine lotion can help relieve discomfort and prevent complications.

Other homeopathic substances, including colloidal oatmeal, sandalwood powder, baking soda, aloe vera, and Epsom salt, can also soothe itchiness.

For more serious instances of inflammation, your healthcare provider might prescribe a topical steroid.

Preventing Heat Rash

Prevention is best. First, stick to more breathable clothing made from cotton and moisture-wicking fabrics. 

When the weather is hot and humid, stay in the shade or air conditioning and keep your sleeping area cool and well ventilated. Plus, avoid thick ointments and lotions that can clog your pores and any drying body soaps that contain dyes or fragrances. The important thing to remember is all heat related illnesses are preventable.

How long does heat rash last without treatment?

For most people, it will generally go away on its own without treatment within a few days. However, how long your rash lasts can depend on factors like where it’s located on your body, how severe it is, and whether you’re using home remedies to help alleviate some of the symptoms.

In most cases, heat rashes will clear up on their own within days. However, you should see your doctor if your rash gets worse, or if you notice signs of infection. This can include:

• Increased swelling, pain, redness, or warmth around the affected area
• Golden yellow crust formation or pus draining from lesions
• Swollen lymph nodes in the neck, armpit, or groin
• Fever or chills

What is prickly heat ?

Miliaria is a disease that belongs to the group of simple dermatitis. Most often it affects infants and young children. But under certain conditions, adults also suffer.

What does prickly heat look like?

It is characterized by the appearance of bubbles or nodules on the surface of the skin. It all depends on the type of sweatshirt. But a common symptom is redness and irritation of the skin. And then it’s worth understanding its form, and here there will already be separate distinguishing features.

Types of miliaria

Crystalline miliaria

thereby contributing to the accumulation of sweat in this superficial layer. It is called crystalline because it appears as bubbles with a clear liquid. They can be opened without harm to health, and there is nothing wrong with that. In some ways, they resemble acne, only the liquid is transparent, and the bubbles themselves are painless. At the same time, there is no sign of inflammation with such prickly heat.

Red prickly heat

This is the most common type of this disease. And the most common reason for its appearance is overheating, high temperature, and, accordingly, increased sweating. Blockage of pores in this case occurs in the epidermal part of the ducts. And this already causes inflammatory processes. In this case, small red spots form on the skin.

Posttular prickly heat

This type of disease is rather rare, because it is actually a complication of prickly heat. Usually a person treats red and does not reach this stage. This prickly heat is also called yellow. It is characterized by more severe and advanced inflammation. And, accordingly, the spots that are visible on the skin are more saturated.

Causes of heat rash This applies to both air temperature and body temperature. For example, if a person has a fever. This is hot weather, this is synthetic clothing that does not allow air to pass through and does not allow the skin to breathe, it does not absorb perspiration well. T It can also be caused by ultraviolet radiation, skin oils, low-quality cosmetics and perfumes. Occasionally, adult prickly heat can be caused by walking medical devices: electrons, heart monitors, etc.

On the face

The main cause of prickly heat on the face is cosmetics and artificial blockage of pores. This is extremely rare and is usually expressed as a slight reddening or crystal prickly heat.

On the neck

Again, this is cosmetics, perfume. But most often the physical effects on the skin: irritation from friction, synthetic fabric and so on.

On the back

Heat and synthetic fabric are the main causes of prickly heat on the back.

In the groin

First of all, this is a physical impact. Constant friction, constant movement leads to severe irritation and inflammation of the skin. Further, synthetic fabric, synthetic underwear leads to severe clogging of pores. And all this together leads to sweating.

Could there be a complication?

There can be only one complication. As we said earlier, prickly heat can turn into yellow. Just more severe inflammation. But it won’t lead to anything terrible.

Symptoms of prickly heat


900 03

The complaints that a person will present with miliaria are rash, itching and discomfort. With allergies, there can be all kinds of localization, which may not even be characteristic of prickly heat. With allergies, the reddening of the skin will be more intense and the itching will be more intrusive and irritating.

Diagnostic 900 36

First of all, it should be said that there is no need to engage in self-diagnosis, let alone self-treatment. Any impact on the disease without a doctor’s examination completely “washes away” the picture for a specialist. The doctor must diagnose, determine the disease and prescribe treatment. In the case of prickly heat, you don’t even have to do any tests and scrapings. According to the description of the patient’s symptoms and external examination, the doctor will be able to determine the diagnosis.

Home treatment

hygiene regimen. So, regular bathing with hypoallergenic detergents is necessary. It is also worth removing immediately all the cosmetics that were used. Other chemicals should also be avoided, especially if you have recently started using a new powder, or dish detergent, or conditioner, etc. If a person himself understands that this is prickly heat, then drying agents with zinc go further into battle. Powders, 1% solution of boron or salicylic acid, decoctions of sage, calendula and St. John’s wort.

Medications

Medicines are prescribed by doctors. For prickly heat in adults, creams and ointments containing zinc and with a drying effect can help: for example, zinc ointment, Sudocrem. If complications appear and a secondary infection has joined, then antibiotic ointments are used: Baneocin, Fucidin and others.

In addition, it is necessary to exclude friction of the skin with clothing and observe proper nutrition: after all, overweight people are more prone to prickly heat. Good cosmetics for skin care and bathing will not hurt either. It’s good if you start a tradition of going to the bathhouse once a week. It cleans the pores well, plus scrubbing is very useful. But do not forget about the measure. Skin diseases are very easy to confuse. Often different diseases have common symptoms. Therefore, in any case, with skin problems, you should immediately contact a specialist. Author: Alexey Kravchenko *prohibited on the territory of the Russian Federation Miliaria – health articles Miliaria – a rash in the form of clear blisters or red nodules that occurs due to blockage of the sweat glands and is most often caused by overheating of the body. By the nature of the rashes, red, crystalline and papular miliaria are distinguished. Diagnosis of prickly heat is usually not difficult, a consultation with a dermatologist may be required only in complicated cases. The treatment of prickly heat is mainly to eliminate the factors that cause overheating and excessive sweating of the body. Measures to prevent prickly heat include the optimal temperature regime of the room, clothing adequate to the weather, personal hygiene and proper skin care. Causes Mostly, prickly heat affects skin areas with insufficient ventilation: areas of natural body folds (armpits, groin, knee and elbow bends),0331 area under the mammary glands in women and very obese men, area behind the ears in children and adults with thick hair, the area between the thighs, if the legs are very full, an area that is constantly under clothing (the area under a bra, swimming trunks, diapers), bandages, dressings. Contribute to the development of prickly heat: synthetic clothing, dense non-breathable fabrics, feverish conditions, elevated air temperatures combined with high humidity, injuries and chafing of the skin, the use of creams, oils, fatty bases of cosmetics that clog pores, diabetes mellitus, metabolic diseases, overweight . Causes of excessive sweating may include malfunctions in the endocrine system of the body, insufficient functioning of the heart, blood vessels, kidneys, and disorders of the nervous system. Sometimes an increase in sweating (hyperhidrosis) is influenced by a genetic factor, i.e. heredity and place of residence. In hot countries, acclimatization is always accompanied by increased sweating, and the locals are prone to hyperhidrosis. Symptoms It is generally accepted to divide prickly heat into three types: Crystal prickly heat manifests itself in the form of pale red small multiple bubbles up to 1 mm in diameter, located close to each other. The blisters are painless and do not cause any other symptomatology, except for the external manifestation. tend to merge. They occur on the forehead, face, neck, torso, flexion surfaces of the arms and legs. In the vast majority, it occurs suddenly and resolves on its own. Red prickly heat is characterized by vesicular rashes on the skin up to 2 mm, which are surrounded by a red halo of inflammation. Inside the bubble is cloudy content. Often accompanied by inflammation of the surface layer of the skin and severe itching. As it progresses, wet crusts appear – a sign of a bacterial infection. Typical localization sites are the armpits, abdomen, skin between the buttocks, elbows and forearms. Such prickly heat in the groin is a common occurrence in obese women. Doesn’t go away on its own. Papular prickly heat is a type of red prickly heat with a severe course. In fact, it is a continuation of red prickly heat. There are papular-vesicular vesicles 1-2 mm in diameter with an acute inflammatory process in the surface layer of the skin (microbial eczema). Itching is possible due to dry skin. Papular miliaria is accompanied by general intoxication: low-grade fever, soreness of the affected skin, swelling and hyperemia. Occurs on the lateral surfaces of the chest, abdomen, arms or legs. Requires long-term treatment for several months. Diagnosis Diagnosis of prickly heat usually does not cause difficulties for a doctor of any specialty. Therefore, to confirm the diagnosis, a visual examination by a pediatrician or therapist is sufficient. In difficult cases, a consultation with a dermatologist may be required. Treatment Prickly heat can occur at any time of the year, but most often it manifests itself in a hot period when we sweat a lot. It can also appear on vacation in warm countries. It is necessary to treat prickly heat, and as soon as possible. You can get rid of a mild form in one to two weeks. In severe cases, the sweat glands become exhausted over time, leading to dry skin. Against the background of deep prickly heat, infection and microbial eczema can penetrate. And it is already much more difficult to fight it – treatment can take years. This is another reason why it is worthwhile to do tests without delay. In newborns, during the treatment of prickly heat, the cream should be discarded, replacing it with a powder that will absorb excess moisture and allow the skin to breathe. Chamomile decoction can be added to bathing water, which soothes the skin and helps to restore it. And do not forget about the need for daily air baths.
