A skin rash can be caused by many things, from allergies to eczema. Some people have itchy or painful bumps that start off red and turn into patches over time. Others may suffer from heat rashes when they’re in too hot of an environment for a long period of time while others get them after being bitten by bugs like mosquitoes.

Sometimes it’s difficult to tell what type of skin problem you have because they all have similar symptoms. In this article, we will explore 3 reasons why you might get a skin rash and how to fix it.

What is a skin rash and what causes them

A skin rash is a general term for any red or pink patch on the skin that itches, burns, and causes pain. It can be caused by many things including allergies, eczema, heat rash (aka prickly heat), shingles, insect bites, and stings.

A skin rash may or may not be accompanied by an itchy rash. They are similar but not the same condition:

  • Skin Rash: An inflamed area on the external skin due to either bacterial infection or allergic reaction
  • Itchy Rash: Rashes that are accompanied by intense itching; often caused by dryness or eczema

Whether its a skin rash or itchy rash, there are many possible reasons that may cause them, for example:

1. Allergies

Allergies are one reason why people develop itchiness within their skin rashes; sometimes these allergies are environmental and seasonal like pollen from trees in the springtime or mold spores during humid weather conditions. Other times they are caused by some type of food like peanuts or shellfish.

2. Eczema

This is another common reason why skin rashes develop and are itchy, scaly, red patches on the skin that may bleed if scratched too much; these often itch when they get wet from sweat or water.

3. Heat rash

Also know as prickly heat, heat rash also cause a person to have an uncomfortable skin rash which might be red with little bumps all over their body due to excessive sweating in hot conditions such as saunas, sun bathing for long periods of time without using sunscreen lotion, wearing synthetic fabrics next to your skin leading to overheating.

Other causes

Another possible reason is pregnancy. While pregnant, some women’s skin changes often include blotchy red patches in different places on the body from what’s normal for someone who isn’t pregnant.

These are caused by hormonal shifts during pregnancy changing how much oil is produced in the skin.

How to figure out if you have a skin rash

If you can answer yes to any of these questions, then you most likely have skin rash:

  • Have you been around anyone with a skin rash?
  • Do your clothes itch or feel uncomfortable on the skin?
  • Does it look like hives (small red bumps)?
  • Is your skin red and swollen and get more irritated by scratching or picking at the scabs?
  • Does this area of skin have cracked, dry patches that are intensely itchy and can’t be scratched because they bleed easily?

Why do I get skin rash

There are many reasons why someone could develop skin rashes which include: heat rash, allergens (such as pollen), pregnancy changes, hormone fluctuations, and irritation by substances such as detergents or dyes.

Blisters are common in skin rashes because the skin is inflamed and overreacting to heat. Heat rash can be triggered by excessive sweating and humidity, as well as immodest attire such as tight clothes or bathing suits.

If you have this type of skin rash, your clothing may feel uncomfortable on the skin, itch, or burn. You will most likely notice a red patch on an area that has been exposed to heat for some time (such as underarms).

How to treat and fix your skin rash

Here’s what you need to know about how best to treat them.

Skin allergies should be treated with a topical cream and antihistamines.

Eczema can be treated in various ways but the best treatment is to take care of your skin by using moisturizers, avoiding scratching it (especially when you have an infection), washing bed sheets often, wearing breathable fabrics such as cotton so that sweat isn’t trapped on the skin.

Some people find relief from eczema if they change their diet. To give this more thought speak to your doctor about what might help work for you.

For those who suffer from chronic eczema, it would be best to visit a dermatologist to receive proper diagnosis and treatment.

There are many options for treating chronic eczema. Standard treatment options include using topical steroids and moisturisers.

If you eczema is extensive or difficult to treat with creams alone, you may consider using light therapy (phototherapy), oral immunosuppressants or newer injection biologic medications like Dupilumab.

Heat rash should be dealt with by staying cool indoors or outdoors, drinking plenty of water to keep hydrated, changing clothes frequently; avoid synthetic materials especially against hot sun exposure which may make heat rash worse.

Home remedy tips for preventing future rashes from happening

Aside from medication, there are also plenty of home remedies you could try to treat and avoid getting an itchy rash.

Try wearing clothes that are more breathable and avoiding certain substances (such as soap) which can irritate the skin. You can also look into these home remedy treatment options:

Aloe vera gel

If you have skin that is red and inflamed, aloe vera can help reduce the pain of a rash. It also contains anti-inflammatory properties which work to relieve swelling and itchiness. You do not need an actual plant to keep on hand because there are many over-the-counter products containing aloe vera extract for treating skin conditions such as rashes.

Soothing oatmeal baths

The oatmeal bath will soothe irritated skin by drawing out toxins from your skin and will help reduce itchiness. Take a bath with oats, baking soda, or any other skin soothers.

Epsom salt bath

Epsom salt is an excellent remedy for skin conditions such as eczema and psoriasis because it helps to relieve pain. Dissolve about 30 grams of Epsom salts in your bathtub before you bathe, once a week if possible.

Cucumber rinse

The cucumber is often our go-to option for skin relief. It’s soothing, refreshing and can be applied in any room of the house!

The medicinal properties that come from this vegetable are just one reason to always keep a few on hand if you’re prone to dryness or have sensitive skin. The natural ingredients within make it an appealing choice when other topical remedies might not seem so desirable due to side effects like drowsiness and dizziness which may interfere with your daytime routine at work or school.

Eating healthy

“The best way to solve any medical condition is through diet,” says Catherine Ulbricht, M.D., founder of Natural Dermatology Solutions in Boston. “If you’re having problems with your skin rash, try increasing your consumption of fresh fruits and vegetables as well as protein from lean sources like beans or fish.”


Skin rashes can happen to anyone, but the severity of them varies substantially. There are many causes and treatments for a rash that may be alleviated with some simple home remedies or by consulting your doctor about what course of action is best suited for you.

Preventative measures such as staying hydrated and avoiding irritating substances like detergents will also help keep skin healthy if you’re prone to getting a rash.
