If you’ve spent a summer in Florida, you’ve probably gotten a heat rash. Or at least seen someone with one.

Heat rash is the itchy, red bumps that appear in the fold of your skin after sweating too much. It is also known as “prickly heat” because of the uncomfortable sensation it causes.

While heat rashes are common during the summer months, this condition can be avoided by taking precautions to prevent sweat from getting trapped in your skin.

What Causes Heat Rash?

When you sweat, your body releases water through your skin. Normally this occurs without any problems.

However, when you sweat too much and too quickly, the moisture has nowhere to go. As it builds up on your skin, your pores become clogged leading to a rash that typically shows up on your neck, back, upper chest and inner thighs.

Heat Rash

Heat rash, also known as prickly heat or miliaria, is a general term for painful irritation of the skin caused by excessive sweating. Heat rash can surface when your sweat ducts become blocked and perspiration can’t escape to the surface of your skin.

Heat rash usually clears up on its own after you’ve moved out of the hot environment and cooled off. But it can be very uncomfortable in the meantime, so here are some ways to get rid of heat rash fast.

What Does Heat Rash Look Like?

Heat rash can show up anywhere on the body that gets hot and sweaty in humid conditions, but it’s most common on areas that rub against each other, such as the inner thighs. In mild or moderate cases, heat rash looks like a mild sunburn or an area of red bumps. In severe cases, heat rash can actually cause little blisters.

How to Prevent Heat Rash

We all have those days where we just have to brave the heat—whether it’s because your car broke down on the hottest day ever and you had to walk home or because you’re in charge of a grill-fest for a crowd of friends at your house. If you know you’ll be exposed to extreme heat, try these tips for

Heat rash is a skin disorder that occurs when sweat ducts become blocked. It is caused by excessive sweating. Heat rash (also called prickly heat, summer heat, miliaria, or fire ant bite) appears most often in hot, humid climates.

It is most common in babies and small children because their sweat ducts are not fully developed. Adults can get it too, however.

Heat rash often clears up in 2 to 3 days with home treatment. You can lower the chances of getting heat rash again by keeping the affected area cool and dry.

You might have heat rash if you have:

A cluster of small red bumps on your body (especially in skin folds).

A prickling or stinging feeling on the skin.

Small blisters and clear, fluid-filled bumps that may itch.

It’s summertime and the living is easy. BBQs, beaches, and picnics are just a few things you’re looking forward to. Not to mention all the extra time you get to spend with your friends, family and little ones. But as any parent knows, summer can also bring some not-so-fun challenges, especially when it comes to taking care of your little one. Heat rash—or miliaria rubra—is one of those challenges.

This summertime rash usually occurs in young children (ages 3 months to 2 years) due to blocked sweat glands or excessive sweating during hot weather. The rash appears as clusters of small red bumps or pimples on the face, neck, chest and in the diaper area. It can be itchy at times but it is harmless and will go away on its own within a few days (usually 24-48 hours).

So what can you do while your little one suffers through this rash? Here are a few simple tips that may help soothe your child’s skin:

– Cool baths (use cool water, add oatmeal if you have it)

– Keep room temperature cool

– Loose cotton clothing

Just as the name suggests, heat rash occurs when your sweat glands are blocked and you cannot sweat. It most commonly develops in babies and young children because their pores are smaller than an adults. When it’s hot, a baby’s body sweats to prevent overheating. The sweat gets trapped under the skin causing a hot, prickly feeling.

There are three types of heat rash:

1. Miliaria crystalline – this is called ‘prickly heat’. The glands that make sweat get blocked and so sweat accumulates just under your skin. If the rash is mild, you may have tiny red bumps on your skin that look like small pimples. With more severe forms of prickly heat you may also have larger blisters that are filled with clear fluid. When these blisters burst they can leave small raw areas on the skin which can become infected if they get dirty or they aren’t kept clean and dry.

2. Miliaria rubra – it’s thought that this type of heat rash is caused by inflammation in the deeper layers of sweat glands, rather than by blockage. You can have red bumps and blisters on your skin that contain a milky fluid which can be itchy

Heat rash is a real summertime bummer. The skin-irritating condition, which happens when your sweat glands get clogged and cause red bumps on your body, is super uncomfortable — especially when it hits in the most inconvenient spots like your upper thighs or under your boobs.

To help deal with heat rash, we’ve come up with some of the best home remedies that are easy to find — you probably already have them on hand somewhere. While some of these methods might seem a little unconventional, the itchiness and discomfort will be worth it (we promise).

Heat rash, or miliaria rubra, is a common skin condition caused by excess sweating in hot weather.

Heat rash can occur at any age, but it’s most common in babies and young children. It also affects adults who exercise in hot weather or are heavily overweight.

If a person is affected by heat rash, they may experience:

* a red or pink rash on the skin

* small spots that look like pimples

* itchy skin

* a stinging or prickling sensation on the skin

Heat rash is not serious and most cases clear up on their own within a few days. However, there are things you can do to ease the symptoms and prevent heat rash from developing again.
