Sweat Rash vs Chafing: What’s the Difference

If your skin gets irritated in summer, between your thighs, under your boobs, or around your belly folds, you’ve probably wondered: is this chafing or a sweat rash? They can look and feel similar, but they’re caused by different things. Knowing which one you have helps you treat it properly and prevent it from coming back.

What Is Sweat Rash

Sweat rash, also called heat rash or intertrigo, happens when sweat and heat get trapped in skin folds. When skin can’t breathe properly, moisture builds up and creates the perfect environment for bacteria and yeast to grow. That’s when redness, itchiness, and stinging start. It’s most common under the belly, breasts, or groin area, where skin sits against skin and stays warm or damp. Sweat rash usually feels hot, itchy, or stingy, sometimes with small red bumps, and can feel raw if moisture lingers.

What Is Chafing

Chafing is caused by friction when skin rubs against skin, fabric, or clothing. You don’t need to be drenched in sweat to get it, but moisture definitely makes it worse. Chafing is more of a rubbing irritation that leaves skin feeling sore, red, and sometimes burning. It usually feels raw or tender, looks smoother rather than bumpy, and gets worse with movement or tight clothing.

The Key Difference

Sweat rash is triggered by trapped moisture and heat, while chafing is caused by repetitive rubbing. Sweat rash tends to feel itchy and rashy, while chafing feels more like a burn or soreness. Sweat rash usually affects areas that stay still and warm, like under-boob or apron belly folds, whereas chafing shows up where skin moves against skin, like the inner thighs or under sportswear.

How to Treat and Prevent Both

For sweat rash, you want to absorb moisture and keep the area cool and dry. A body powder or cream-to-powder formula with ingredients like zinc oxide, aloe vera, or panthenol can help calm irritation and prevent bacterial growth. Powder works best in areas that don’t rub much, like under the belly or breasts.

For chafing, you want to reduce friction and protect the skin barrier. That’s where the Glydelle Anti Chafe Stick comes in. It forms a smooth, breathable layer that helps skin glide instead of rub. The blend of coconut oil, jojoba, and vitamin E also keeps skin soft and hydrated. On extra humid days, try layering: a light powder first to absorb moisture, then your Glydelle stick on top to create smooth protection.

So Which One Do You Have

If your skin feels itchy or rashy, it’s likely sweat rash. If it feels burnt or sore, it’s probably chafing. And if it’s both, that’s completely normal. Many people experience a mix, especially in hot weather.

The Bottom Line

Both sweat rash and chafing are completely normal and nothing to be embarrassed about. They just need slightly different care. One focuses on moisture, the other on friction. At Glydelle, we’re all about products that support real skin and real bodies.
