Heat rash is a common skin condition that can show up when it’s too hot and you sweat a lot. It makes the skin sting and feel prickly, it can also make the skin itch. Some people call heat rash “prickly heat”, but doctors call it miliaria crystallina or miliaria rubra.

Anyone can have a heat rash, but it is more common in babies and young children. A heat rash can look like tiny bumps surrounded by red skin and usually appears on areas where you sweat most, including the:


  • Belly
  • Back
  • Upper chest
  • Groin
  • · Neck
  • · Armpits
  • · Under the breasts


It can also appear in skin folds and parts of the body where skin can rub against clothing.


Symptoms of heat rash can include:

· Small bumps and spots

· Mild swelling

· An itching and prickling sensation on the skin

It can also appear as red spots on fair skinned people.



Heat rashes usually happens in places with humid and hot weather. Or when you sweat too much and the ducks from the sweat glands become blocked. This causes the sweat to leak to the surrounding tissues that can lead to irritation and redness.

This condition is also common to newborn because their sweat glands haven’t fully developed yet.



Heat rash usually goes away even without treatment. But there are available over-the-counter medicines that you can use to relieve the symptoms of heat rash. This can include calamine lotion, which can help relieve with the itching, and antihistamine medicines. You can also use hydrocortisone cream, with your pharmacist or doctor’s approval, to treat inflammation. You may also need antibiotic if your skin becomes infected.


If you experience heat rash, here are some of the simple and common tips that can help you relieve with the symptoms:

· Keep your skin dry as much as possible

· Cool down to avoid sweating. You can also try to avoid heat and humidity, stay in an airconditioned room or fan

· Wear loose fitting clothes. This can help you prevent from itching too much

· Take a cool bath or shower to provide comfort from itching. But don’t shower too much as it can also strip the skin its natural oils


Heat rash is not a dangerous or contagious condition. But if symptoms last longer than a few days or if signs of infections appear, consult your medical provider immediately.
