Treatment, Symptoms, Causes, and More
Heat rash is a skin condition that often affects children and adults in hot, humid weather conditions. You can develop heat rash when your pores become blocked and sweat can’t escape.
Many different types of skin rashes exist. They can be concerning, uncomfortable, or downright painful. Heat rash is one of the most common types.
Different types of heat rash can range in severity, and they all look a little different.
Miliaria crystallina
This is the most common and mildest form of heat rash. If you have miliaria crystallina, you’ll notice small clear or white bumps filled with fluid on the surface of your skin. These bumps are bubbles of sweat that often burst.
Contrary to popular belief, this type of heat rash doesn’t itch and shouldn’t be painful. Miliaria crystallina is more common in young infants than in adults.
Miliaria rubra
This type, or “prickly heat,” is more common in adults than in children and babies. Miliaria rubra is known to cause more discomfort than miliaria crystallina because it occurs deeper in the outer layer of the skin.
Miliaria rubra occurs in hot or humid conditions and may cause:
- itchy or prickly sensations
- red bumps on the skin
- a lack of sweat in the affected area
- inflammation and soreness of the skin because the body can’t release sweat through the skin’s surface
Bumps that appear due to miliaria rubra can sometimes progress and fill with pus. When this happens, doctors refer to the condition as miliaria pustulosa.
Miliaria profunda
Miliaria profunda is the least common form of heat rash. It can recur often and become chronic, or long-term. This form of heat rash occurs in the dermis, which is the deeper layer of skin. Miliaria profunda typically occurs in adults after a period of physical activity that produces sweat.
If you have miliaria profunda, you’ll notice large, tough, flesh-colored bumps.
Because heat rash prevents sweat from leaving your skin, it may lead to nausea and dizziness.
These images show the difference between the three types of heat rash.
Heat rash usually resolves without treatment in a few days. If the discomfort becomes too severe, you can try methods at home that help soothe itching and reduce skin temperature.
Some medicines/creams you can buy to manage heat rash include:
- Over-the-counter (OTC) hydrocortisone cream applied 1-2 times a day can help soothe itching.
- OTC antihistamines can also take an effect against itching.
8 home remedies for heat rash
Aside from OTC medications and creams, there are a number of herbal or non-medicinal remedies that might soothe the redness and itching. These include:
- Apply a cold compress. Using an ice pack or chilled cloth can help you bring down redness, swelling, and itching. If using an ice pack, be sure to wrap it in a towel or old t-shirt — you don’t want to experience freezer burn.
- Take a low-temperature bath. A cold or lukewarm shower can also help you reduce the temperature of your skin and soothes itching. It might help to try an exfoliant to help open the affected pores.
- Keep indoor temperatures cool. Use a fan or air conditioning to cool down your room. If you’re on bed rest, it’s important to move around to let air circulate your body.
- Stick with loose, cotton clothing. This allows air to move around your body and keep it cool. Choosing lightweight, breathable, natural fabrics rather than synthetics might also help you avoid irritation and stay comfortable.
- Take a colloidal oatmeal bath. A 2015 study of colloidal oatmeal extract suggests that the possible anti-inflammatory and antioxidant effects of oat might be behind its potential itch-soothing effects.
- Use topical pine tar. Used by people to manage skin conditions for thousands of years, applying pine tar to itchy or inflamed areas can reduce itching and inflammation, according to one 2016 review.
- Apply Aloe vera gel to the area. Aloe vera is another well-established topical remedy for skin ailments that may help soothe your itchy skin.
- Mix sandalwood with water and applying the paste to your heat rash. An older 2011 study found that sandalwood, a herb common to Ayurvedic traditional medicine, might help you reduce inflammation across a number of skin conditions.
Heat rash often causes symptoms in sweat-prone areas, like:
- the face
- the neck
- underneath the breasts
- beneath your scrotum
The symptoms can involve:
- small raised spots called papules
- an itching sensation
- slight swelling
On lighter skin
The spots may appear red.
On darker skin
The spots can be more understated and harder to identify on darker skin. But a dermatologist or physician will be able to see them using a dermoscopy, where they use a small, lighted microscope to zoom in on the skin.
For people with darker skin, the spots might appear as white globules with darker halos around them.
Heat rash occurs when pores become clogged and can’t expel sweat. This is more likely to happen in warmer months or climates, or after intense exercise.
Wearing certain types of clothing can trap sweat, leading to heat rash. Using thick lotions and creams can also lead to heat rash.
It’s possible to get heat rash in cooler temperatures if you wear clothes or sleep under covers that lead to overheating. Babies are more likely to develop heat rash because their pores are underdeveloped.
Friction on the surface of the skin often causes heat rash. Adults usually develop heat rash on the parts of their bodies that rub together, like between the inner thighs or under the arms. Babies often develop heat rash on their necks, but it can also develop in skin folds like those of the armpits, elbows, and thighs.
Risk factors
Having certain health problems or engaging in certain lifestyle choices can increase your risk for heat rash, including:
- being prone to intense sweating
- regularly engaging in high-intensity physical activity
- taking drugs that trigger sweating like bethanechol, clonidine, and neostigmine
- Morvan syndrome, a rare genetic disorder that causes excessive sweating
- type 1 pseudohypoaldosteronism, a condition that causes a loss of sodium through the sweat glands that has some links to heat rash
Heat rash is rarely serious.
Often, it goes away without treatment in a few days. But you should call your doctor if you begin to experience:
- a fever
- chills
- increased pain
- pus draining from the bumps
Call your child’s doctor if your child has a heat rash that doesn’t resolve in a few days. Your doctor may recommend that you apply lotions like calamine or lanolin to relieve itching and prevent further damage. Keep their skin cool and dry to help relieve heat rash.
Follow these tips to prevent heat rash:
- Avoid wearing tight clothing that doesn’t allow your skin to breathe. Moisture-wicking fabrics may help prevent sweat buildup on the skin.
- Don’t use thick lotions or creams that can clog your pores.
- Try not to become overheated, especially in warmer months. Seek out air-conditioning or carry a handheld fan.
- Use a soap that won’t dry your skin and doesn’t have fragrances or dyes.
Heat rash causes minor discomfort, spots, itching, and swelling.
It usually resolves itself in a matter of days for most people. There are several types that look slightly different than one another.
You can prevent it by staying cool in warmer climates, wearing loose clothing, and avoiding thick creams.
Talk with your doctor if you believe you may have something more serious or if you have a heat rash that frequently recurs.

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
It occurs when superficial obstruction of the ducts of the sweat glands and thus contributes 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 Partniki
complaints that a person will present when they pretend is a 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.
Diagnostics
It is first of all to say that self -diagnostics and even more so self -medication.
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.

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.
Not all medicines can be bought in one place. You can find the necessary medicines in one pharmacy and at a bargain price at the link:

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.

Prickly heat in adults: treatment, symptoms and types
Dermatovenereologist

Prickly heat is a skin irritation that occurs due to the fact that a person sweats a lot and at the same time it slowly evaporates.
As a result, the sweat glands become clogged - and irritation begins. Most often, this disease occurs in children, but it is also sometimes observed in adults - so you need to know about it.
Symptoms
Speaking about the symptoms of prickly heat, it is necessary to immediately touch upon such a moment as the types of irritation, because each type has its own manifestations.
The simplest and safest form is crystal prickly heat. It is manifested by small (up to a millimeter) painless rashes - these are small bubbles that are located next to each other and can merge. Such rashes are localized on the neck, face, forehead, torso, as well as in the places where the legs and arms are bent. Often this prickly heat occurs briefly and quickly disappears with the observance of the usual hygiene.
More dangerous is this type of prickly heat, like red (inflammatory). Its signs are the following:
- Rashes in the form of larger vesicles (up to two millimeters) with red, inflamed corollas.
In these vesicles, the content of a cloudy appearance is observed. - Itching, which can be quite severe and disturb the patient with discomfort.
- Wet crusts. If they appear, this means that a bacterial infection has joined the usual illness in an adult - that is, a complication has arisen.
Usually, the red variety of the disease is localized under the armpits, on the abdomen and the skin between the buttocks, as well as on the bends of the elbow, forearms. In obese people, it often appears in the groin. Unlike the previous option, this one does not go away on its own and always requires targeted treatment.
If the course of red prickly heat is complicated, the so-called papular form with acute inflammation may develop. Here already appear not only itching, but also symptoms of intoxication. The skin is painful, the patient's condition is complex. Such a disease can be cured only with specially selected medicines - in some cases, this requires more than one month.
Another variant of prickly heat in adults is apocrine. It is associated with the work of special glands that are located on the areola of the nipple, in the anus, armpits, and also in women in the labia majora. In these places, a small rash appears, as well as specific accumulations in the area of \u200b\u200bthe glands. These formations often burst right inside the skin and an infectious process joins them. In this case, the help of specialists is also required.
Causes
The causes of sweating in adults look like this:
- Hyperhidrosis. In people with excessive sweating, the disease can become chronic.
- Serious metabolic disorders. Since sweat is part of the metabolic reactions, some diseases can affect its release and evaporation.
- Certain endocrine pathologies - for example, diabetes mellitus, hyperthyroidism, hypothyroidism.
- Some diseases of the nervous system.
- Fever, elevated temperature for a long time.
In this state, sweat is always actively released, so a rash may occur on the skin. - Obese or simply overweight. With extra pounds, people tend to sweat much more, which can also lead to irritation of the skin.
- Inactivity, constant skin contact with the bed. Such prickly heat in adults occurs in bedridden patients or in people who, due to certain diseases, do not walk much, but lie or sit a lot.
All these are reasons that can be attributed to pathological - that is, they are already associated with some negative state of the body or disease. But there are also so-called provoking factors - they can be called external causes. Here we include:
- Hot, dry climate, conducive to heavy sweating, and high humidity with high temperatures.
- Active and constant sports, in which a person sweats a lot and the sweat itself is constantly on the skin.
- Work involving intense physical activity or exposure to hot environments.
For example, people sweat a lot if they work in factories near red-hot stoves. - Poorly fitted shoes. If it strongly pinches the foot and does not provide enough air, sweating on the skin of the legs may develop.
- The use of incorrect cosmetics: very dense and nourishing creams when the skin is hot. For example, a rash on the face may appear due to the fact that in the summer heat a woman applies a very dense foundation.
- Non-compliance with all hygiene rules, when sweat mixed with dust and dirt remains on the skin for a long time.
- Sun exposure that is too frequent and prolonged, which can damage the skin and make it more susceptible to any negative factors.
Both one cause and a combination of several can cause a problem - it all depends on the particular organism.
Diagnostics
As a rule, the diagnosis of prickly heat does not require complex manipulations - a dermatologist or therapist can determine the disease purely visually, by its external signs.
But in some cases, it is necessary to examine the cells of the affected areas, as well as pass general tests. This is especially true in difficult cases, when, along with the primary problem, it is necessary to identify a secondary infection.
Treatment
If we are talking about a simple form, the treatment of prickly heat will be to eliminate the negative factor (for example, overheating), maintain hygiene and treat the affected skin with antiseptics.
In difficult cases, patients are prescribed antihistamines, antibiotics (not always), antibacterial, anti-inflammatory and drying agents.
The treatment plan may also include:
- Various treatments for hyperhidrosis. For example, this is laser treatment, botulinum toxin injections, nerve fiber surgery, removal of sweat glands. The more serious the operation, the less often it is used, since it is important that its risks are covered by the effect obtained.
- Physiotherapy.
Patients can be prescribed reflex and acupuncture. - Phytotherapy. In some situations, the doctor may suggest using decoctions based on various useful herbs. But this is far from always necessary, as there are many ready-made products with a more pronounced and faster effect.
Difficult cases require mandatory consultation with a doctor; in such a situation, self-treatment of prickly heat in adults is impossible. If you have a similar problem, we recommend that you immediately contact Medicina JSC. In our clinic, you will receive qualified assistance from experienced dermatologists and be able to get rid of the disease as quickly as possible.
Prevention
To understand what kind of prevention is needed in this case, you need to turn to the causes of prickly heat and exclude all negative factors. It is important to maintain the body at an optimal temperature, wear good breathable clothing, constantly monitor the health of the body, and maintain an optimal weight.
