Heat rashes, a problem usually associated with soaring temperatures, is one of the worst downsides of the summer season. Many a cheerful sunny day has been ruined owing to this seemingly unavoidable condition. However, you can learn to easily manage and even prevent a heat rash.

A heat rash is a cluster of small red bumps, which is often surrounded by redness in the skin. A skin area with a heat rash often feels inflamed and uncontrollably itchy and has a severe prickly sensation.


When a sweat pore gets blocked during intense heat, the sweat trapped in the pore can make the surrounding area inflamed and sensitive. Excessive sweating and bacteria overgrowth that results from too much sweating are the two main culprits in this situation.

Heat rashes are very common. Most people are likely to suffer from a heat rash at least once in a lifetime. Usually, the rash subsides on its own in a few days. Infection in a heat rash is very rare.

Summers are not the only time when a heat rash can make an appearance. Hot and congested clothing can even give rise to a heat rash during the winter.

Infants, young children and those who are obese are more susceptible to heat rashes. The sweat pores of infants are not fully developed, making them more likely to develop such a rash. People who are obese often suffer from excessive sweating, making them vulnerable to heat rashes.


Fortunately, the remedies for a heat rash are just as common. You can easily speed up your recovery and prevent future rashes by using some basic ingredients that will help you to get rid of heat rash quickly.

Applying ice on a heat rash can provide immediate relief from inflammation, itchiness and the prickly sensation by numbing the surrounding area. Applying ice can help bring down the temperature of the affected skin, thus preventing the heat rash from spreading any further.

  • Hold the ice pack over your heat rash and gently rub it over the inflamed skin in small circles.
  • Don’t keep the ice pack in the same position for more than 5 minutes. Keep shifting the ice pack to a new position every 3 to 5 minutes.

Apply an ice pack to the heat rash in this manner 3 times a day until the rash subsides.


Method 3: Using an Oatmeal Bath

Things you’ll need:


  • Raw oatmeal (rolled oats) – 1 cup

  • Add in 10 to 12 drops of lavender essential oil.
  • Mix the contents of the bowl with a wooden spoon.

Oatmeal greatly soothes inflamed skin due to a heat rash. It also exfoliates the skin, thus unclogging the sweat pores and speeding up the healing process. Antibacterial soap can help you fight any chance of infection in the rash. Lavender essential oil will bring the pain and stinging down and soothe the skin.

Step 2. Make a bath pouch with the mix

  • Use a kitchen string or any cord to secure the neck of the bundle. Your oatmeal bath sachet is ready.

Run a cool bath and add this bath sachet to it. Soak your entire body, especially the affected skin, in the bath for about 20 minutes.

Soaking in this bath before bed can help you get a good night’s sleep without any heat rash-related discomfort and irritation in your skin.

Method 6: Using Prickly Heat Powder or Calamine Lotion


The most effective defense against a heat rash is keeping the skin dry. Using a prickly heat powder or calamine lotion can keep your skin cool and dry, which helps keep heat rashes at bay. They both also help ease symptoms if you already have a rash.

While there are numerous brands of prickly heat powder available, go with one that doesn’t contain added fragrance that may cause irritation in severe heat rash cases. The prickly heat powder will keep your skin dry and provide relief from severe itching. It can also be used as a preventive measure.

Calamine lotion is a very effective remedy for numerous itchy skin conditions. It keeps the itch at bay and the skin dry, allowing the heat rash to subside.

  • Repeat the application 2 or 3 times a day.

Additional Tips

  • Never apply ice directly on your skin, as it may end up doing more harm than good. Always apply ice wrapped in a thin towel or a cotton cloth.
  • To make the oatmeal bath sachet, you can use any absorbent cotton fabric or muslin.
  • Do not use corn starch on a heat rash that has become infected.
  • Dress comfortably according to the weather. Wear loose clothes of breathable fabric in the summer to allow proper air circulation.
  • Avoid heat and sun if possible and stay indoors in an air-conditioned area. When going outdoors can’t be avoided, try to stay in the shade. You may also use outdoor fans.
