Understanding Prickly Heat: A Common Heat-Induced Skin Condition

Prickly heat, also known as heat rash or eccrine miliaria, is a skin condition that occurs when sweat glands become obstructed, trapping sweat beneath the skin. This trapped moisture leads to inflammation and the characteristic itchy, prickly sensation that gives the condition its name. While commonly associated with hot and humid environments, prickly heat can also result from various everyday activities and situations.

What exactly is prickly heat?

Prickly heat is a skin rash that develops when sweat ducts become blocked, preventing the normal evaporation of sweat from the skin’s surface. This trapped sweat causes inflammation and irritation, resulting in small, itchy bumps on the skin. The condition can be uncomfortable but is generally harmless and typically resolves on its own once the skin is allowed to cool and dry properly.

Types of Eccrine Miliaria: Understanding the Variations of Heat Rash

There are three main types of eccrine miliaria, each affecting different parts of the sweat duct and presenting with slightly different symptoms:

• Miliaria crystallina: Characterized by tiny, clear, fluid-filled bumps on the skin’s surface
• Miliaria rubra: Presents as small, red, itchy bumps and is the most common form of heat rash
• Miliaria profunda: A less common type that affects deeper layers of the skin and appears as flesh-colored or slightly red bumps

How do these types of heat rash differ in appearance?

Miliaria crystallina typically appears as tiny, 1-2mm clear bumps resembling glass beads, most commonly on the head, neck, and upper trunk. Miliaria rubra presents as slightly larger 2-4mm red bumps, often found in areas of friction such as the collar, underarms, and skin folds. Miliaria profunda manifests as 1-4mm bumps on the trunk and extremities, which can be either skin-colored or red.

Who Is Most Susceptible to Developing Prickly Heat?

While anyone can develop prickly heat under the right conditions, certain groups are more susceptible to this skin condition:

1. Newborns and infants
2. Individuals on bedrest
3. People living in hot, humid climates
4. Overweight or obese individuals
5. Those engaging in intense physical activities

Why are babies particularly prone to heat rash?

Newborns and infants are especially vulnerable to heat rash for several reasons. Their sweat glands are still developing, making them less efficient at regulating body temperature. Additionally, parents may inadvertently overdress their babies, creating an environment conducive to heat rash development. The combination of underdeveloped sweat glands and potential overheating makes infants particularly susceptible to this condition.

Common Causes and Triggers of Prickly Heat Rash

Several factors can contribute to the development of prickly heat rash:

• Hot and humid weather conditions
• Intense physical exercise
• Wearing tight, non-breathable clothing
• Prolonged bed rest or immobility
• Fever
• Sudden changes in climate (e.g., traveling to a tropical destination)
• Use of heavy creams or ointments that clog pores

How does clothing contribute to heat rash development?

Clothing plays a significant role in the occurrence of heat rash. Tight-fitting garments and those made from synthetic, non-breathable materials can trap heat and moisture against the skin. This creates an ideal environment for sweat gland blockage and subsequent heat rash formation. Opting for loose-fitting, breathable fabrics like cotton can help prevent this issue by allowing better air circulation and sweat evaporation.

Recognizing the Symptoms of Prickly Heat

The symptoms of prickly heat can vary depending on the type and severity of the condition, but common signs include:

• Small, red, raised bumps on the skin
• Itching or prickling sensation
• Mild swelling or inflammation
• Stinging or burning feeling
• Redness in the affected area
• Skin that feels warm to the touch

Where on the body does prickly heat typically occur?

Prickly heat rash commonly appears in areas where skin-to-skin contact or friction is frequent. These include:

• Neck and collar area
• Underarms
• Groin and inner thighs
• Under the breasts
• Elbow creases
• Waistline
• Back and chest

In infants, heat rash may also appear on the face, neck, and shoulders due to their delicate skin and tendency to be overdressed.

Effective Treatments for Prickly Heat Rash

While prickly heat often resolves on its own once the skin is allowed to cool and dry, there are several treatments that can provide relief and speed up the healing process:

1. Cool compresses: Applying a cool, damp cloth to the affected area can soothe irritation and reduce inflammation.
2. Calamine lotion: This over-the-counter product can help relieve itching and discomfort associated with heat rash.
3. Antihistamines: Oral antihistamines may help reduce itching in some cases.
4. Topical corticosteroids: For more severe cases, a doctor may prescribe a mild corticosteroid cream to reduce inflammation.
5. Cooling powders: Talcum or other cooling powders can help absorb excess moisture and reduce friction.

What is the most effective way to treat prickly heat at home?

The most effective home treatment for prickly heat involves creating a cool, dry environment for the skin. This can be achieved by:

• Taking cool showers or baths
• Using a fan or air conditioning to reduce ambient temperature
• Wearing loose, breathable clothing
• Avoiding heavy creams or ointments that may clog pores
• Applying calamine lotion or cool compresses to soothe the skin

These measures help to reduce sweating and allow the skin to cool, which is crucial for resolving heat rash.

Preventing Prickly Heat: Strategies for Avoiding Heat Rash

Prevention is key when it comes to prickly heat. By taking proactive measures, you can significantly reduce your risk of developing this uncomfortable skin condition:

• Dress appropriately: Wear loose-fitting, lightweight, and breathable clothing, especially in hot weather.
• Stay cool: Use air conditioning or fans to maintain a comfortable temperature in your environment.
• Avoid excessive sweating: Take breaks during physical activities and stay hydrated to regulate body temperature.
• Keep skin dry: Use talcum powder in areas prone to sweating to absorb excess moisture.
• Choose the right bedding: Opt for lightweight, breathable sheets and avoid heavy duvets in warm weather.
• Gradually acclimate to new climates: When traveling to hotter regions, allow your body time to adjust to the new conditions.

How can parents prevent heat rash in infants?

Parents can take several steps to prevent heat rash in their infants:

1. Dress babies in lightweight, loose-fitting clothing
2. Avoid overdressing, especially during sleep
3. Keep the nursery at a comfortable temperature (between 68-72°F or 20-22°C)
4. Use breathable fabrics for bedding
5. Give babies regular “naked time” to allow their skin to breathe
6. Change wet or sweaty clothing promptly
7. Use mild, fragrance-free soaps and avoid heavy creams or lotions

When to Seek Medical Attention for Prickly Heat

While prickly heat is generally a benign condition that resolves on its own, there are instances where medical attention may be necessary:

• If the rash persists for more than a few days despite home treatment
• If there are signs of infection, such as increased redness, warmth, or pus
• If the rash is accompanied by fever or chills
• If the affected area becomes painful or swollen
• If the rash spreads rapidly or covers a large area of the body
• If you experience dizziness, nausea, or other symptoms of heat exhaustion

How can a healthcare provider diagnose and treat severe cases of heat rash?

In severe or persistent cases of heat rash, a healthcare provider can offer diagnosis and treatment through the following steps:

1. Physical examination: The doctor will inspect the affected areas and ask about symptoms and recent activities.
2. Skin scraping or biopsy: In rare cases, a small skin sample may be taken to rule out other conditions.
3. Prescription treatments: For severe cases, the doctor may prescribe stronger topical corticosteroids or antibiotics if there’s a secondary infection.
4. Advice on prevention: The healthcare provider can offer personalized advice on preventing future occurrences based on individual risk factors.

By understanding the causes, symptoms, and treatments for prickly heat, you can better manage this common skin condition and take steps to prevent its occurrence. Remember that while heat rash is usually harmless, persistent or severe cases should be evaluated by a healthcare professional to ensure proper treatment and to rule out any underlying conditions.

Prickly heat (heat rash): symptoms, treatment, and prevention

Hot and humid conditions are ideal for developing prickly heat rash, but they’re not its only cause. Heat rash can be a byproduct of your self-care if you enjoy hot yoga, exercise frequently, or use steam rooms or saunas. Even adding your winter layers too prematurely or throwing an additional duvet onto the bed can trigger it. Here’s everything you need to know about prickly heat rash and what to do about it.

What is prickly heat?

Prickly heat rash is pretty aptly named. It’s a prickly, itchy, and sometimes stinging rash that develops on your skin as a result of heat. Also known as eccrine miliaria or heat rash, the condition occurs when your sweat glands become obstructed. Because of this, sweat is trapped in the skin, resulting in a skin rash.

There are three types of eccrine miliaria — miliaria crystallina, miliaria rubra, and miliaria profunda. The type of heat rash that develops depends on the part of the sweat duct affected, and each has a slightly different presentation.

Heat rash can sometimes be hard to self-diagnose as it can look like a number of other skin conditions and rashes. If you’re having trouble identifying or treating your skin issue, Maple can help. Maple is a virtual care platform that connects you with Canadian-licensed doctors and specialists. With Maple, you can get to the bottom of your skin dilemma by seeing a doctor or dermatologist online from your phone, tablet, or computer.

Who can develop prickly heat?

Under the right circumstances, anyone can develop prickly heat rash, but here are some of the most likely groups.

Newborns and babies are highly prone to heat rash because their sweat glands are just developing. Additionally, they’re also less able to control their internal body temperature. Add that to the tendency for new parents to overdress their little ones, and you’ve got the perfect conditions for developing heat rash.

Babies aren’t the only population with an increased risk for the condition though. Being on bedrest increases your odds of developing prickly heat rash. Remaining in place for long periods of time — like in one position in a bed — hampers air flow to the immobilized areas. Besides precipitating irritation, this also limits the flow of sweat off your body.

Being confined to bed can result in heat rash even under cool or air-conditioned circumstances. But hot and humid conditions — like being in a building without air conditioning in the summer — up its probability.

Additionally, being overweight or obese may amplify your chances of experiencing the condition. This is due to the rolls of skin these individuals are more likely to have. Since the skin folds between these rolls are more likely to retain moisture, rub against each other, and occlude sweat glands, they make prickly heat rash more likely.

What causes prickly heat?

When your body can’t expel your sweat properly through your sweat ducts, it becomes trapped in your skin. With nowhere else to go, this sweat can spread under the surrounding skin, triggering an itchy, inflamed rash.

Keep in mind that heat rash isn’t contagious. However, heat rash can spread all over the body. It can also be triggered by a fever.

Another common cause of heat rash is travelling to a hot and humid climate. In this case, the condition usually resolves as your body acclimatizes to the new weather.

While anything that obstructs the sweat glands can trigger heat rash, certain causes are especially notable. A big one tends to be wearing constricting or synthetic fabrics that don’t allow for air flow — especially during high-intensity exercise. Prolonged bed rest is another as bedding can function as a barricade blocking your body’s sweat glands. Lightweight bedding is one way to help prevent heat rash.

What are the symptoms of prickly heat?

As its name suggests, prickly heat typically causes a prickly or itchy sensation in the skin. With miliaria rubra, the rash manifests in small uniform bumps between 2 to 4mm — about the size of tiny glass beads. You’re most likely to find it in areas that experience a lot of friction like around the collar, under your arms or breasts, or in the creases of your knees and elbows.

Alternatively, heat rash can present as tiny, 1 to 2mm bumps resembling glass beads. This is the case with miliaria crystallina, which is most likely to crop up on the head, neck, and upper trunks of infants, and mainly on the trunk for adults.

Finally, miliaria profunda appears as 1 to 4mm bumps on the trunk and extremities. These can be either skin-coloured or red.

What does prickly heat look like?

Prickly heat rash can look slightly different depending on the person experiencing it. It often appears as small raised red bumps, although the redness of the rash on the skin may not be as obvious on black or brown skin, or darker skin tones. Alternatively, the rash can appear as clear, fluid-filled bumps, leading many to compare it to acne.

How can you prevent heat rashes?

Wearing loose-fitting, lightweight cotton clothing is one of the best ways of avoiding heat rash. Thick and synthetic fabrics are more likely to trap heat, leading you to sweat. To avoid heat rash on hot days or while exercising, focus on wearing light layers that you can remove as you heat up. You’ll also want to drink plenty of water to avoid dehydration.

Newborns and small babies are more vulnerable to heat rash and can’t tell you when they’re getting too hot. While fall weather can tempt you into breaking out your baby’s thick winter sleep sack, unless you’re camping they’re probably unnecessary. Most houses sit somewhere around 21°C (70°F). This means that even when the thermometer dips outside, your baby’s room is likely pretty comfortable.

To ensure your baby is warm enough, avoid touching their hands or face. Because of their distance from your baby’s core, these will feel cool to the touch even when your baby is perfectly comfortable.

Instead, place a hand on your little one’s back or belly. If these feel warm, there’s no need for another layer. It’s hard not to worry, but your baby doesn’t require more layers than you do.

To further avoid repeat heat rashes, consider doing the following:

• Limit your exposure to hot and humid conditions, including steam rooms and saunas
• Cool off after sweating or an intense exercise session with a lukewarm shower
• Seek out air conditioning or use a fan when it’s hot
• Treat fevers with antipyretic, or fever-reducing medications like acetaminophen or ibuprofen

How long does prickly heat usually last?

The good news is that prickly heat rash doesn’t stick around for that long. Your symptoms should resolve within a day or two. If they’re not markedly better after day four, consider speaking with a healthcare provider.

Can you get rid of prickly heat fast?

Because prickly heat rash can result in inflammation, soothing your skin is often a good start to addressing the condition. A great way to do that is by using a cooling compress, or by wrapping an ice pack in a towel and applying it to the affected area. You’ll also want to avoid scratching the rash if possible to help prevent infection.

Additionally, you can take an antihistamine. This will help to calm the swelling and reduce the itchy, prickly feeling that the rash brings. But, while you can minimize the worst of its effects, these strategies won’t get rid of prickly heat rash entirely. Luckily, the condition should clear up within a day or two.

What are the most common treatments for prickly heat?

In addition to ice and antihistamines, there are a few other ways to soothe the redness, itching, and discomfort of your prickly heat rash. These include:

• Taking an oatmeal bath — while keeping your heat rash dry is important, bathing in oatmeal is an exception. Oatmeal contains avenanthramides, which are compounds with anti-inflammatory and anti-itch properties that help to soothe your skin. Just make sure to gently pat yourself dry afterwards instead of rubbing off with a towel. Exposing your damp skin to friction can make your rash worse.
• Applying an over-the-counter (OTC) hydrocortisone cream — this can help to relieve the worst of your symptoms. If your symptoms are severe or the area of your rash is quite large, however, you may require a prescription hydrocortisone cream.
• Applying calamine lotion — this may help to calm the itching associated with your heat rash.
• Using aloe vera — this helps to soothe rashes caused by prickly heat. Aloe is often used for treating sunburns due to its cooling and anti-inflammatory properties, and despite being a gel-like substance, it won’t block your pores. This makes it safe for addressing prickly heat rash.
• Keeping the affected area dry and cool. Heat and friction got you here in the first place, and exposing your rash to them will only make it worse. Do your best to keep your skin cool and dry until it’s had the chance to heal. While you’re at it, avoid ointments or other topicals that will block your pores, as this may worsen the rash.

When to see a doctor for heat rash

Heat rash will usually disappear on its own within a few days. While it can be uncomfortable, you’re unlikely to need to see a doctor.

In certain circumstances, however, you should speak to a doctor about your prickly heat rash. These include if your rash isn’t getting better, or seems to be getting worse after day three or four, as it’s a possible sign that you’ve developed a secondary infection. Likewise, if your heat rash is extremely painful, it’s a good idea to see a healthcare provider. They may be able to prescribe hydrocortisone cream to clear it up quicker.

In young children or those who are immunocompromised, some symptoms may indicate a secondary infection. If your child has what looks like heat rash and any of the following, it warrants a visit with their healthcare provider:

• An accompanying fever
• Swelling around the rash
• Drainage of pus from the affected area
• Chills

Additionally, if your heat rash is accompanied by headache, dizziness, nausea or vomiting, or feeling very weak or thirsty, you may be experiencing heat exhaustion or heatstroke. While you can usually deal with heat exhaustion safely at home, heatstroke is a medical emergency and requires immediate intervention.

If you’re not sure whether you’re experiencing heat rash, it’s a good idea to speak to a dermatologist for clarification. Some skin cancers can appear as rashes in their early stages, making proper diagnosis crucial. While seeing a dermatologist can take months, with Maple, getting a dermatology consultation takes less than 24 hours. Even better, you don’t need a referral.

Cholinergic urticaria: Symptoms, treatment, and causes

Cholinergic urticaria (heat bumps) can occur when a person’s core body temperature rises. Possible causes include exercise, stress, weather, and eating spicy foods. Small, round, itchy papules appear that usually fade within an hour.

The lesions typically resolve without treatment between a few minutes and an hour later. They usually have no lasting effects, but some people may avoid exercise and other activities to prevent urticaria. In rare cases, however, a severe reaction may develop.

The word “cholinergic” refers to a part of the nervous system that controls muscle contraction, blood vessel dilation, and slowing of the heart rate.

In this article, we look at the signs and symptoms of cholinergic urticaria, why it happens, and how to treat or prevent it.

Cholinergic urticaria tends to appear soon after a person’s body heats up. It can occur anywhere but is more likely to affect the trunk or arms.

The lesions that occur with cholinergic urticaria usually:

• measure 1–5 millimeters (mm) across
• are small and numerous
• are round and raised
• are the same color as the person’s skin
• are itchy
• last from a few minutes to one hour

The rash may include any combination of the following features:

• itching or tingling at the onset of the rash
• burning or itching in areas affected by the rash
• areas of small wheals or raised bumps on the skin
• larger wheals that lead to more significant areas of swelling
• angioedema, or swelling of the deeper layers of the skin

In rare cases, heat bumps may be linked to other problems throughout the body, such as:

• headaches
• diarrhea
• heart palpitations
• abdominal cramps
• low blood pressure
• bronchospasm, a tightening of the muscles in the airways
• wheezing or shortness of breath
• asthma

In some instances, a person may develop anaphylaxis, a life threatening allergic reaction that needs emergency medical attention.

Anaphylaxis is a severe allergic reaction that can be life threatening. The symptoms develop suddenly and include:

• hives
• swelling of the face or mouth
• wheezing
• fast, shallow breathing
• a fast heart rate
• clammy skin
• anxiety or confusion
• dizziness
• vomiting
• blue or white lips
• fainting or loss of consciousness

If someone has these symptoms:

1. Check whether they are carrying an epinephrine pen. If they are, follow the instructions on the side of the pen to use it.
2. Dial 911 or the number of the nearest emergency department.
3. Lay the person down from a standing position. If they have vomited, turn them onto their side.
4. Stay with them until the emergency services arrive.

Some people may need more than one epinephrine injection. If the symptoms do not improve in 5–15 minutes, or they come back, use a second pen if the person has one.

Was this helpful?

Cholinergic urticaria can result from any activity that causes excessive sweating.

Examples include:

• exercise
• hot baths
• sitting in a sauna or hot tub
• being in a warm room
• exposure to hot temperatures, such as hot weather
• having a fever
• being angry or upset
• stress
• eating spicy food
• consuming alcohol, in some cases

Experts believe the sweating process and a release of histamine contribute to the reaction, but they do not know precisely what happens.

The body tends to release in response to an allergic reaction.

To diagnose cholinergic urticaria, a doctor will likely consider the symptoms and ask the person what they were doing when they started.

In some cases, they may ask a person to take a warm bath or do some exercise to see how urticaria appears.

A doctor can inject a drug called methacholine into a person’s skin to see if cholinergic urticaria develops. However, they are unlikely to use this test as it cannot reliably diagnose or rule out cholinergic urticaria.

Treatment and management options vary between individuals.

They include:

• medications, such as:
  • antihistamine, for instance cetirizine (Zyrtec)
  • ketotifen (Zaditor), an antihistamine and asthma medication
  • danazol (Danocrine), an anabolic steroid, in some cases
  • Omalizumab (Xolair), an anti-IgE monoclonal antibody
  • beta-blockers such as propranolol, alongside other treatments
• lifestyle changes to avoid triggers, such as:
  • avoiding places and activities that warm the body
  • cutting out spicy foods
  • limiting alcohol consumption
• stress management techniques, if stress appears to contribute
• ultraviolet (UV) phototherapy

While treatment may help, it may not completely prevent cholinergic urticaria.

Some dietary choices may help reduce the risk of overheating the body’s core and therefore of developing cholinergic urticaria.

It may help to avoid:

• hot drinks
• spicy foods
• alcoholic drinks

What are some tips to reduce body heat?

In most cases, cholinergic urticaria is not serious. It often lasts 15–30 minutes, and the rash will fade on its own 90 minutes after starting the activity that triggered it.

Cholinergic urticaria often starts between the ages of 10 and 30 years and gradually stops happening over time.

Here are some questions people often ask about cholinergic urticaria.

How do you get rid of cholinergic urticaria?

The rash will fade after a person stops the activity that caused the reaction. Avoiding situations that lead to overheating and sweating can prevent it. This is not always possible, however, and doctors can prescribe medication to resolve or prevent a rash.

Should I worry about cholinergic urticaria?

In most cases, cholinergic urticaria goes away when the person stops the activity that caused it and does not have any serious effects. In some cases, however, a person may develop a more severe reaction. If the rash occurs with other symptoms, the individual should ask a doctor for advice. Severe swelling and breathing difficulty may be signs of anaphylaxis, a life threatening reaction that needs immediate medical attention.

What does cholinergic urticaria feel like?

A rash of small bumps can appear on the skin. They may be itchy, prickly, or burning. Sometimes, larger bumps or wheals may develop with more severe swelling.

How long does cholinergic urticaria last?

It usually passes within a few minutes to an hour. According to DermNet NZ, wheals usually last 15–30 minutes, and the overall rash should disappear 90 minutes after starting the activity that triggered it.

Cholinergic urticaria is a type of hives or skin reaction that occurs when the body temperature rises. Experts do not know precisely how it happens, but the sweating process may play a role.

People who experience frequent or long lasting symptoms may wish to speak to their doctor about ways to manage the condition.

If a person experiences other symptoms, such as breathing difficulty, they should seek immediate medical attention.

Features of prickly heat in children and adults

The disease is provoked by external factors and often occurs in summer, when traveling to countries with hot climates and high humidity. Almost everyone knows what prickly heat looks like, but many mistakenly consider it a problem only for young children.

When overheated and in heat, all people experience increased sweating. In closed areas of the skin and in the folds, its evaporation slows down, the ducts of the glands are clogged and a “greenhouse effect” is created. As a result, foci of irritation appear with rashes, swelling, redness, burning and itching.

Where prickly heat appears

Prickly heat in newborns and infants of the first year, young children can be caused by excessive wrapping, imperfect thermoregulation, improper care of delicate skin, high temperature in ARVI. Rashes are localized on the body – the back and upper chest, neck, folds in the groin and armpits.

In adults, the disease provokes profuse sweating during warming compresses, wearing tight synthetic clothing in the heat, obesity, poor hygiene and endocrinological pathologies. Prickly heat appears on the legs and arms in the knee and elbow cavities, on the face – especially on the forehead in women when using dense creams.

Both office workers, who have to wear trousers in hot weather, and those who like skinny jeans, face the “sauna effect”. In this case, prickly heat in men occurs between the legs, in the anorectal region, on the scrotum and causes severe discomfort.

Do not confuse prickly heat with diaper rash, which also occurs in people of any age and gender and is often localized in similar places. They are provoked by prolonged exposure to moisture and friction, and there is no pronounced rash on the swollen, reddened skin.

Types of prickly heat

There are four forms of prickly heat, which differ in symptoms and duration.

Crystalline

Eruptions on the body (back, chest) in this type of prickly heat are very small blisters with a clear liquid. They are not accompanied by reddening of the skin, can appear even when overheated during physical exertion and disappear on their own after a couple of days.

Red

Small cloudy vesicles and nodules cover large areas of hyperemic skin. Affected areas may merge with each other. In constantly wet folds, inflammation is accompanied by burning. Red prickly heat occurs on the neck, armpits, groin, under the mammary glands and lasts up to two weeks.

Yellow and white

In this form, blisters with purulent contents appear, which indicates the addition of an infection, usually staphylococcal. The disease often develops as a result of ignoring prickly heat and complete blockage of the ducts, their rupture and infection. The treatment can take up to a month.

As a complication of miliaria, newborns may develop vesiculopustulosis. Eruptions appear in the upper back, in the folds of the skin, on the head. They quickly transform into pustules, which open themselves or become covered with a crust.

How to treat prickly heat

If the disease in the crystalline form can still be dealt with at home, but it is better to deal with the rest under the supervision of a specialist. With timely access to a doctor, the treatment of prickly heat does not take much time and relieves complications.

Comprehensive approach includes:

• Elimination of provoking factors – correction of skin care and hyperhidrosis, change of cosmetics and transition to natural fabrics.
• Selection of drugs for the treatment of prickly heat – ointments, antiseptics, powders, creams.
• When rashes appear, you need to contact a dermatologist who will determine their cause and knows how to get rid of prickly heat of any form. This will help to avoid the development of a strong inflammatory process, infection and the appointment of antibacterial agents.

Prickly heat on the skin appears in hot and humid temperature conditions with increased sweating. The “sauna” effect, which limits the natural evaporation of sweat, increases the likelihood of skin irritation. When the ambient temperature rises, the body turns on adaptive organisms, trying to cool itself. Prolonged skin irritation with substances leads to inflammation of the openings of the sweat glands.

Peculiarities of male prickly heat

Accumulation of sweat under the epidermis is typical for areas that lack free access to air. Prickly heat in the groin in an adult man often appears due to the need to walk all year round in pants and only occasionally in shorts. Most often, the rash affects the front and inner thighs, groin and buttocks. Drivers, office workers, sellers in rooms without air conditioning, when sitting for a long time, find pimples under their knees.

Prickly heat in the groin occurs on the scrotum or around the anorectal region. Reddened skin with small red dots can pinch and itch. Depending on the amount of sweat, blisters or papules appear.

Main signs of prickly heat:

• red pimples or bumps;
• itching, tingling and pain;
• redness and swelling;
• sensation of heat;
• pustules and red streaks;
• swollen lymph nodes.

The symptoms of miliaria resemble skin irritation caused by allergic reactions and viral infections . The appearance of a rash is not associated with the use of drugs, certain foods, or the application of cosmetics.

In any case, you need to see a doctor, as it is not always easy to distinguish between urticaria and allergies. It is believed that when the skin is stretched in the lesion, the bubbles disappear. But this only applies to certain types of prickly heat.

There are four main types of heat rash

1. Crystal prickly heat looks like beads of sweat sticking to the skin, goes away gently without causing many symptoms.
2. Red prickly heat – is associated with profuse sweating against the background of high air temperature, therefore it is the most common, accompanied by burning and itching. Blockage of the sweat glands causes inflammation.
3. White or yellow heat rash appears at the stage of formation of pustules against the background of prickly heat. Pustules can be the first signs of a skin infection, then a consultation with a dermatologist is required.
4. Deep prickly heat appears with repeated episodes when the sweat glands remain inflamed in large areas of the skin. The manifestation is large hard bumps. They can be provoked by physical exertion or prolonged walking in tight clothes in the heat.

Prickly heat can be caused by a variety of factors: being overweight and wrinkled skin, tight or warm clothing in hot weather, thick creams and lotions, and medications.

Causes of prickly heat in the groin

The most common causes of blocked sweat glands in the groin:

1. The skin is in contact with neighboring areas, which prevents sweat from evaporating.
2. Tight clothing around the hips prevents moisture from escaping and also increases body temperature.
3. Patches, oily creams and ointments can clog sweat glands.

Since prickly heat is the result of clogged pores, the cause of this phenomenon must be eliminated. The factors of its appearance are: profuse sweat, scales of dead epithelium, bacteria.

Allergy to synthetic fabrics, washing powder or shower gels can cause skin irritation. Violation of the rules of personal hygiene in the summer contributes to the development of pathology.

Rash provoke conditions that increase sweating:

1. Heart failure, tuberculosis, hypothyroidism can cause profuse sweat.
2. Imbalances of the endocrine system change reactions to cold and heat, violate thermoregulation.
3. Infectious diseases accompanied by fever lead to sweating.
4. Injuries, fractures are associated with immobility, poor removal of moisture on the skin.

The best ways to get rid of prickly heat

The first step is to cool the skin, keep it dry to slow down sweating and help get rid of excess sweat:

• take a cool shower;
• dry the skin well with a towel and hold it outdoors;
• change into clothes made from natural fabrics.

Pay attention to when the rash develops, change location or take care of coolness – turn on the air conditioner or go into a refrigerated room, look for shade and sit until the body cools down. Be sure to replenish the fluid supply. Take a shower or bath to wash away substances that have accumulated on the skin and will further clog pores.

Traditional methods

Some home remedies are suitable for prickly heat in the groin:

1. Oatmeal bath: add three tablespoons of soda to one cup of ground cereal. Avoid scented gels, foams and soaps.
2. Complete drying of the skin before dressing, preliminary drying of the body with a towel without friction.
3. Exposure of areas affected by prickly heat, if the situation permits. Use baby powder or cornstarch to absorb excess sweat and avoid diaper rash.
4. Cold compresses from wet towels. But do not allow the creation of a sauna effect.
5. Ditch tight underwear for boxer briefs made from lightweight, breathable fabrics. Change underwear in time if it becomes damp from sweat.

Most prickly heat goes away on its own. But when severe discomfort appears, it is necessary to help the skin.

Natural remedies are the first aid against prickly heat:

1. Aloe vera juice – just break off a small piece of the leaf, remove the skin with thorns and apply the juice from the pulp to the affected areas. The pain subsides almost immediately.
2. Lavender or peppermint oil has cooling, healing, soothing properties. You can add a few drops of oil to your bath or apply directly to your skin.
3. Decoctions of string and chamomile for bathing and rubbing the affected areas: take one tablespoon of the herb in a glass of boiling water, leave for 30 minutes, dilute with cool water before use.

Treatment of prickly heat with drugs

Treatment of prickly heat in the groin is determined by the severity and type of rash. To begin with, it is necessary to make regular hygiene procedures – in the acute phase, take 3-4 showers in hot weather. Wear cotton or viscose that wicks away moisture. Choose underwear and loose-fitting trousers. These measures help to cope with prickly heat at an early or mild stage. Antiseptics are used to help the skin:

1. Affected areas of the skin are treated with a solution of potassium permanganate, boric or salicylic acid. To avoid overdrying, non-greasy creams or ointments are immediately applied.
2. Zinc ointment or “Desitin” is suitable for disinfection and reduction of inflammation, containing vaseline, lanolin, fish oil and talc in addition to zinc oxide. The action of salicylic and zinc acids combines Lassar paste. The Xeroform powder is based on the action of bismuth salt, which disinfects, promotes wound healing and relieves inflammation.
3. An anti-inflammatory effect with the removal of edema, redness and soreness is provided by an ointment from prickly heat with panthenol (“D-panthenol” and “Bepanten”). Dexpanthenol, represented by provitamin B, is quickly absorbed, penetrates into cells and degenerates directly into vitamin B. In this form, the substance ensures the regeneration of mucous membranes at the cellular level, improves vascular function.
4. Preparations with a complex composition include La-cree cream with licorice extract, shea butter and jojoba oil, beeswax, lecithin for regeneration and inflammation relief.

Any applied ointments should be completely absorbed before putting on clothes and clothes, and mashes and solutions should dry on the skin.

The first signs of prickly heat between the legs and in the groin should be met with preventive measures:

• treat reddened and damp places with talc or baby powder, which is important for those who like to wear jeans in the heat;
• apply a weak solution of potassium permanganate, hydrogen peroxide to the surface;
• apply anti-itch ointment with betamethazole, which will accelerate healing.

If irritation persists for a long time, it is better to ask a doctor than to smear prickly heat yourself.

With a moderate rash, a bacterial process joins the inflammation and blockage of the ducts. Secondary infection requires detection and identification of the pathogen. The surface of the wounds is sensitive to the appearance of erosions, therefore it is necessary to add antibiotic therapy, which is determined based on the analysis of sensitivity to drugs.

In addition, regenerating compositions and talkers, decoctions of chamomile, calendula or oak bark are applied. The complex uses UV therapy, which stimulates the production of vitamin D and skin regeneration.

In severe prickly heat, two directions of therapy are used:

• antibiotics eliminate the cause of inflammation and infection, taken orally or in the form of creams (Ciprofloxacin, Azithromycin in tablets and Levomekol and Tetracycline in ointments).
