Heat rashes and fungal rashes are common during the summers. Although similar in appearance, they may differ in cause, symptoms, and treatment. Here is how you can differentiate between a heat rash and a fungal rash. Tap to know!

Cause Of Rash

A heat rash may occur on the skin due to blocked sweat glands, whereas a fungal rash occurs due to a fungal infection.

Location On The Body

Heat rashes may appear on sweaty areas like the neck or back; however, a fungal rash occurs in moist folds like groin or underarms.

Appearance

If you experience tiny red bumps, it might be a sign of heat rash, while red, itchy, and ring-shaped patches may indicate fungal rash.

Itching and Discomfort

A heat rash can cause mild irritation or stinging sensation but a fungal rash can cause intense, persistent itching.

Moisture and Spread

If left untreated, a fungal rash can spread throughout the body. However, a heat rash usually stays in one place.

Duration

A heat rash can go away on its own in a few days, whereas a fungal rash can last longer and needs treatment.

Information Credits

According to PubMed, a heat rash is linked to sweat retention in blocked glands, while fungal rashes occur from the overgrowth of yeast in warm, moist skin folds. It is advisable to consult a healthcare professional for personalised suggestions.
