What Is a Heat Rash?

Miliaria is a type of red or pink skin irritation that usually develops in the summer and appears on portions of the body covered by clothing. It appears predominantly on the neck area, upper chest, groin, in the elbow creases, and under the breasts. The skin irritation is more common in babies, but is can also affect adults as easily, causing discomfort and itching. It looks like a cluster of pimples or blisters. Sweating a lot can also contribute to the forming of prickly heat.

What Causes Miliaria?

Usually, the cause of the rash is overdressing during extremely warm days. Overdressing leads to sweating, which in very hot and humid weather can block the sweat ducts, allowing the sweat to enter the skin cells. This is how portions of tiny inflammations are formed and this is how the rash takes shape. But what exactly causes the sweat ducts to block? There is a germ called Staphylococcus epidermidis that usually lives on your skin and forms a sticky substance, which combined with excessive sweat and dead skin cells leads to blocked sweat ducts.

What Are the Symptoms of a Heat Rash?

The most common symptoms are those itchy bumps that appear on the skin and that can sometimes cause a prickly feeling similar to the one of a mild sunburn. However, the symptoms also range according to the type of heat rash you are experiencing.

There are three types of heat rash:

  • miliaria crystalline, which happens at superficial layers of the skin and looks like small beads of sweat;
  • miliaria rubra, which is the most common one, that appears in the deeper layers of the skin and causes larger blisters and redness of the affected area;
  • or miliaria profunda, which appears after repeated episodes of miliaria rubra and it causes even larger skin-colored blisters.

How Can You Prevent a Heat Rash?

If you want to prevent getting a heat rush this summer, here are a few tips that will help:

  • Try not to overdress during really hot days and keep close to air-conditioning as much as possible.
  • Don’t dress in really tight clothes, your skin won’t be able to breathe properly and it is much more likely that you will get a heat rash under these conditions. Try to wear loose clothes from fabrics such as cotton.
  • Keep in mind that lotions or creams that are too heavy can also contribute to clogging your pores.
  • It is also advisable to be careful what type of soap you use. Avoid using one that dries your skin or that contains fragrances or dyes.
  • Avoid excessive physical activity during really hot days or in humid weather.
  • Shower as frequently as you can – it will prevent your skin glands from getting clogged.
  • Make sure to sleep in a cool and well-ventilated area.
  • Alternatively, you can exfoliate your skin and remove the dead skin cells that could be clogging your sweat glands.

What Is the Best Heat Rash Treatment?

The good news about a heat rash is that under normal conditions it should clear up by itself in a couple of days. But there are things that you can do in order to speed up that process. Check out these heat rash treatment options and decide for yourself which is the best:
