You may be able to relieve heat rash with products like hydrocortisone cream and antihistamines. Some home remedies, including cold baths and using air conditioning, may help the heat rash go away.

Heat rash is a painful skin condition that often occurs in hot weather.

The symptoms of heat rash include small clusters of tiny, raised bumps on discolored, irritated skin. A prickly, burning or itchy sensation may also accompany heat rash.

Heat rash is also known as prickly heat, sweat rash, or miliaria rubra.

Although it can appear anywhere on the body, heat rash often appears around skin folds, including:

  • in the neck
  • near the groin
  • under the arms

Heat rash occurs when excessive sweating blocks sweat pores. You’re most likely to get heat rash if you live in a hot, humid climate. Babies are particularly likely to get heat rash, especially if they’re overdressed.

Most of the time, heat rash isn’t serious and often goes away in cool temperatures. However, it can be very uncomfortable and can get worse if excessive sweating continues.

Let’s take a look at several ways you can soothe heat rash at home.

Your doctor may recommend several over-the-counter or prescription medications to treat heat rash.


A doctor may recommend you use ointments such as calamine lotion to treat the symptoms of heat rash. This lotion has a number of benefits for the skin, partly because it contains zinc oxide.

It can help treat heat rash by soothing itchiness. Dab some calamine lotion onto your rash using a cotton pad. Reapply as needed.

A range of calamine lotions is available for purchase online.


Over-the-counter antihistamines — whether topical or oral — can relieve the itching associated with heat rash. If you’re giving an antihistamine to a child, be sure to talk with your pediatrician or pharmacist about which types are best.

Steroid creams

Hydrocortisone cream, a type of corticosteroid, may help relieve symptoms of heat rash. It’s available over the counter at any pharmacy and can be applied once or twice a day to soothe itching.

While you can use it short term on your baby’s skin, don’t apply it under the diaper. It could further irritate the skin.

There are many home remedies for heat rash. Some soothe your skin or cool it down, while others reduce inflammation and itching while preventing infection.

It’s important not to scratch your rash. Scratching can lead to more irritation and possibly an infection.

Cool baths and showers

Heat rash usually eases up after the skin is cooled down. Bathing in cool water can help with this. Washing the skin gently can also unclog the pores. This is crucial since clogged pores contribute to heat rash.

Ensure that you dry your skin properly after bathing. Skin that’s left wet can become irritated.

Fans and air conditioners

While your skin heals, avoid excessive sweating and humid air. Ventilation is important in letting your rash dry out and stay cool. When possible, stay in an air-conditioned room, or use an air fan.

Light, moisture-wicking clothes

As your skin heals itself, it’s essential to avoid clothing that irritates your skin or makes you sweat more. Moisture-wicking clothing that’s light and loose-fitting can help your skin heal without irritating it.

Look for certain polyesters and other synthetic fabrics designed for fitness and sporting activities. These will be particularly suited for wicking moisture.

Cotton, while not a moisture-wicking fabric, is quite breathable. It might be comfortable to wear as well.

Ice packs or cold cloths

Cold compresses are great for soothing irritated skin. Face cloths soaked in cold water, or ice wrapped in a cloth, can reduce the pain and irritation associated with heat rash.

Here’s more information about making your own cold compress.


Oatmeal can be effective at reducing itching and inflammation. This makes it a useful home remedy for heat rash and several other skin conditions.

Put 1 or 2 cups of oatmeal in a lukewarm bath and soak for 20 minutes. Make sure the water isn’t hot, so you don’t further irritate your skin.

You can also make a paste with oatmeal and water and apply it to your skin. Mix 1 part oatmeal to 1 part water, and mix until it forms a paste.

You can shop for soothing colloidal oatmeal here.


Research suggests sandalwood is an anti-inflammatory and analgesic, meaning it may reduce pain. Sandalwood powder mixed with a little water and applied to the rash can reduce the burning, painful sensation associated with heat rash.

Mix 2 parts sandalwood powder with 1 part water to make a pastelike substance. Before applying it to your rash, test it on a small patch of unbroken skin. If you don’t react after an hour, you should apply it to the rash without any further issues.

Baking soda

Baking soda (sodium bicarbonate) can soothe itchy skin. It’s also something most of us have in our pantry. This makes it a great home remedy for heat rash and other itchy skin conditions.

Add 3 to 5 tablespoons of baking soda to a lukewarm bath and soak for about 20 minutes.

Learn more about using baking soda on your skin here.

Aloe vera

Aloe vera is an anti-inflammatory and antiseptic that can cool down the skin while preventing infections. This can help soothe swelling and pain. Use aloe vera gel directly on your heat rash to relieve the discomfort.

Unscented talcum powder

Talcum powder reduces sweat by absorbing perspiration. In turn, this ensures the pores aren’t blocked.

Use unscented talcum powder, as scents might irritate your skin. Apply a little on sweat-prone areas like your underarms, backs of your knees, and inner thighs. Coat the skin and let it sit as if it were an antiperspirant deodorant.

Find talcum powder here.


Neem (margosa) can help treat a number of skin rashes. Some research has shown it has antimicrobial and anti-inflammatory properties. However, human studies are limited.

You can combine neem powder with water to make a paste. This paste can be applied to the rash, left on for a few minutes, and washed off. You can also add neem powder to a lukewarm bath.

Epsom salt

Epsom salt (magnesium sulfate) has a range of claimed health benefits. According to anecdotal accounts, a lukewarm bath with a cup or two of Epsom salt may relieve itchiness.

If you give a child an Epsom salt bath, make sure they don’t swallow any water. When consumed orally, Epsom salt is a laxative. In excess, it can cause diarrhea.

You can buy Epsom salt online here.

Provided there are no complications, your heat rash should disappear within a few days of starting home treatment.

The rate it takes to disappear depends on how severe the rash was initially and whether you’re treating it effectively. If your rash worsens after a few days, you may need to speak to a healthcare provider.

While there are a number of effective home remedies for heat rash, you might need a doctor’s guidance if any complications occur.

You should also contact your doctor if a rash doesn’t go away within a week of starting treatment, or if you start to develop a rash after starting any new medication.

You should also consult your doctor if a rash seems infected. Symptoms of infected skin include:

  • pus
  • oozing
  • white or yellowish fluid
  • increased pain
  • swelling

Take your child or baby to the doctor immediately if they have:

  • fever
  • sore throat
  • muscle aches
  • any other flu-like symptoms

Since heat rash occurs when your body overheats and sweats, you can prevent heat rashes by staying cool.

To prevent heat rashes, take the following precautions on hot days:

  • Stay in air-conditioned, cool areas.
  • Drink plenty of water.
  • Don’t wear excessive layers of clothing.
  • Avoid too much physical exertion.
  • Take cool showers or baths.

Parents should ensure that children and babies stay cool, hydrated, and dressed comfortably. Be sure you’re changing your baby’s diaper frequently, too. Wetness can contribute to heat rash.

Should heat rash occur, there is a range of home remedies available to treat it. These include cold showers and compresses, as well as a variety of ointments and medications.

Heat rash (prickly heat) – NHS

Heat rash is uncomfortable, but usually harmless. It usually gets better on its own after a few days.

The symptoms of heat rash are:

  • small, raised spots

The symptoms of heat rash are often the same in adults and children.

It can appear anywhere on the body and spread, but it cannot be passed on to other people.

Heat rash appears as raised spots that are 2mm to 4mm across. Some spots may be filled with fluid.

To keep your skin cool

  • wear loose cotton clothing
  • use lightweight bedding
  • take cool baths or showers

  • do not use perfumed shower gels or creams

A pharmacist can help with heat rash

Speak to a pharmacist about heat rash. They can give advice and suggest the best treatment to use.

A pharmacist might recommend:

  • calamine lotion
  • antihistamine tablets
  • hydrocortisone cream – though not for children under 10 or pregnant women as they need to get advice from a doctor before using this treatment

Non-urgent advice: See a GP if:

  • the rash does not improve after a few days
  • your baby has a rash and you’re worried

Causes of heat rash

Heat rash is usually caused by excessive sweating.

Sweat glands get blocked and the trapped sweat leads to a rash developing a few days later.

Babies often get heat rash because they cannot control their temperature as well as adults and children can.

Heat stroke and sunstroke: symptoms and first aid



6 July

If dangerous symptoms appear, there is no time to think.

Signs that heat stroke is coming

Heat stroke is overheating. It happens when the body for some reason cannot cool down, that is, return to a healthy temperature. It is considered to be values ​​from 36.1 to 37.2 ° C.

The causes of overheating can be different: heat, high physical activity, lack of moisture in the body. In general, it doesn’t matter. Heatstroke is equally dangerous, regardless of what caused it.

Sunstroke is a special case of heat stroke. This is a local overheating of the head caused by direct sunlight.

Fortunately, heat stroke does not happen all at once. He has a harbinger – thermal exhaustion. This is a growing condition that signals: the body cannot cope with thermoregulation, it needs urgent help to cool down.

Heat exhaustion can be recognized by the following signs in various combinations:

  1. Pale, cold, clammy skin.
  2. Dizziness.
  3. Weakness and confusion.
  4. Sensation as if it were getting dark before the eyes.
  5. Increased perspiration.
  6. Headache.
  7. Nausea, slight vomiting.
  8. Rapid heartbeat.
  9. Muscle spasms and cramps.
  10. Dark urine (color indicates dehydration).

Symptoms of heat stroke

If you missed the stage of heat exhaustion and it came to heat stroke, the symptoms will be even more unpleasant:

  1. Body temperature above 40°C.
  2. Labored breathing.
  3. Profuse vomiting.
  4. Fainting.
  5. Serious cardiac arrhythmias.
  6. Possible damage to internal organs due to heat shock.
  7. Malfunctions in the brain.

All this is very dangerous, not only your health, but also your life is at stake. So take immediate action. Moreover, it is desirable already at the stage of thermal exhaustion.

Heat exhaustion first aid

If we are only talking about the initial symptoms of overheating, the first aid algorithm looks like this.

  1. Stop physical activity.
  2. Get out of the sun (out of a hot room) into the shade, into a light draft, into a room cooled by an air conditioner.
  3. Remove all clothing if possible.
  4. Place gauze or a towel soaked in cool water on the forehead.
  5. Drink at least 1-2 glasses of water. This is necessary to eliminate possible dehydration and give the body moisture to produce an adequate amount of sweat.
  6. Drink rehydron or an isotonic sports drink. Such a liquid contains electrolytes important for metabolism and the functioning of the nervous system. And you could lose them with intense sweating.

First Aid for Heat Stroke

If you or someone around you has already suffered from heat stroke, local assistance may not be effective. Vomiting, cardiac disturbances, pre-syncope are observed – immediately call an ambulance.

Heatstroke is a medical emergency and the person experiencing it needs urgent help.

While the ambulance is on its way, follow the same procedures as for heat exhaustion. To increase the effect, they can be supplemented with “heavy artillery”:

  1. Surround the victim with ice packs (frozen vegetables and berries are also suitable), wrapped in a thin sheet.
  2. Place the person in a cold water bath to quickly lower the critical temperature. Attention: this advice can only be used if you (the victim) are assisted by other people. Diving alone is dangerous.

Arriving doctors will assess the patient’s condition. If pre-medical first aid for heat stroke is provided on time and is effective, hospitalization will not be necessary. However, doctors may put you on an IV to replace electrolytes lost with moisture, and suggest blood and urine tests and an ultrasound to determine the condition of the internal organs. With results of analyzes go to the therapist. He will tell you what to do next.

Prevention of heat and sunstroke

If you have had heat stroke, you will be particularly sensitive to high temperatures in the coming week. Therefore, follow these precautions carefully.

1. Drink more water

Ideally, 2-4 cups of fluids (water, fruit and vegetable juices) every hour you spend in direct sunlight at a high temperature. Especially if you are still doing physical labor in the heat. To sweat effectively, your body needs more moisture than usual. Don’t let it be scarce.

2. Try to spend the hottest hours indoors. Avoid exercising in direct sunlight during this period.

3. Wear light-colored light clothing

Clothing should be as loose as possible to facilitate air circulation around the body.

4. Don’t forget your hat

A hat or panama hat will help prevent sunstroke. A cap and a bandana are not very suitable on a hot day: it is better to choose a light and wide-brimmed headdress.

5. Take frequent cool showers or baths

This will lower your body temperature.

6. Do not drink alcohol or drinks with caffeine

They promote dehydration and constrict blood vessels. Because of this, the body produces less sweat than it needs to cool down.

7. Monitor urine color

Dark is a sign of severe dehydration. Look for a few more non-obvious signs in this article.

      After recovering from fainting, give the victim weak sweet tea.

      Visit a doctor

      In any case, after suffering from heat stroke, the victim should visit a doctor. The consequences of heat stroke can harm the human body even if first aid is provided correctly and on time (the brain, organs of hearing, vision, nervous system, etc. can be affected).

      In addition, the doctor can give the necessary recommendations for the victim (for example, adhere to a sparing regimen).


      Some people are prone to relapse after heat stroke, so it is much better to avoid overheating by following simple rules.

      To prevent heat stroke, there are general recommendations:

      • Use clothing made from natural materials
      • Wear light hats when outdoors
      • Regularly ventilate and cool the rooms in which you are
      • 1.5 – 2 liters of water per day)

      • Avoid physical activity during peak hours of sunshine (approximately 11 am to 4 pm)
      • During hot hours, minimize the consumption of alcohol and carbonated drinks

      In the city, you should also remember that:

      • When leaving the house, you must have a bottle of water with you
      • It is undesirable to visit crowded places during the hours of the greatest solar activity (approximately from 11 am to 4 pm)
      • Try not to travel by public transport during rush hours

      Remember to wear a helmet when cycling. If you are driving during peak hours of sunshine, try to drive in the shade and drive more slowly. Be aware of the dangers of exercising in hot weather.

      If you feel sick while you are going to work, stand in the shade and drink some water. If possible, sit down. Call relatives or friends, report your location. Ask them to call an ambulance if you don’t call back in 10 to 15 minutes. Remember, it’s better to be late than get a heatstroke.

      In Moscow, a practice was introduced during the hottest times to distribute free bottles of water in the metro lobbies. Ambulances are on duty at the station entrances at the same time.

      If it’s sunstroke

      Sunstroke is a form of heat stroke that occurs when the head or naked body is exposed to direct sunlight. This type of overheating has more severe consequences for the brain and nervous system.

      First aid and symptoms of sun and heat stroke are the same. However, a person who has been in the sun for a long time is worth watching for a while. Overheating may occur several hours after exposure to direct sunlight.
