Remedies For A Heat Rash


The summer is fast approaching, that means you have to get ready to protect yourself against the pesky summer heat.  Heat rash is a big umbrella that covers a few similar yet different skin problems.

Miliaria Crystallina- Green Light

Miliaria Crystallina is one of the skin conditions that fall under the heat rash umbrella. It is the most common and mildest form of heat rash. Most people who have Miliaria Crystallina will notice a patch of small white bubbles filled with fluid. Usually, the bubbles would appear on your back or on the top of your arms but rashes can occur in other places.

Here are a few:

  • face
  • neck
  • abdomen
  • groin
  • elbow

The fluid inside the bubbles is most often sweat, these bubbles tend to burst on their own. Like most things Miliaria Crystallina has an upside, generally this kind of rash doesn’t itch or burn. In fact, this rash will remedy itself.


Miliaria Rubra- Yellow Light

Miliaria Rubra, or as most people know it as prickly heat, is a little more concerning because it occurs deeper in the outer layer of skin. More adults than children tend to get Miliaria Rubra, but when a child does get it, it’s quite severe. The bad news keeps rolling once you find out that you don’t have to be in direct sunlight for this rash to occur, so watch out Floridians humidity counts too.

The telltale signs of Miliaria Rubra are:

  • itchy or prickly sensations
  • red bumps on the skin
  • a lack of sweat in the affected area
  • inflammation or soreness of the skin.

The treatment for a rash like prickly heat would be the same as if for any rash, simply wash the affected area with soap, wear light clothing, and stay hydrated. Most people will start to see their rash clear up in days but if your heat rash persists, it’s best to go see a healthcare professional.


Miliaria Profunda- Red Light

Miliaria Profunda is the top tier of heat rash and unlike the previous kinds, this one is like the terminator…it keeps coming back. Although Miliaria Profunda is the least common, it is the most severe, causing adults who contract it to abstain from doing rigorous physical activity. If you have Miliaria Profunda, you’ll notice a patch of larger, tough, flesh-colored bumps. It is not unusual to have dizziness or lightheadedness. Long-term effects can leave most adults nauseous and dehydrated.


The most important bit of information to leave you with is when to call a doctor. Heat rashes are rarely serious, often it goes away without treatment. However, you should call your doctor if you begin to experience: fever, chills, increased pain, or pus draining from the bumps.  Your doctor may recommend that you apply lotions to ease the pain. All in all, you can say prevention is the best cure, wearing sunscreen and keeping out of the sun when possible is the most ideal remedy.
