As summer heat and humidity rise, heat rash—also known as prickly heat or miliaria—often follows. This common skin condition affects adults, pregnant women, and babies alike, causing itchy red bumps that can be both unsightly and uncomfortable.
Understanding its triggers and applying proven strategies can help you avoid it or soothe it quickly. Here are 8 effective home remedies and prevention tips, drawn from dermatological best practices and natural skincare expertise.

Heat rash occurs when sweat ducts become blocked due to high temperatures and humidity. Normally, sweat evaporates to cool the body, but in hot, humid conditions—especially with tight clothing—pores clog, trapping sweat and forming small, fluid-filled red bumps.

Heat rash can appear anywhere, including the back, face, neck, chest, abdomen, arms, legs, shoulders, and forehead. It's also common in skin folds like armpits, groin, elbows, knees, and toes—areas prone to sweating.
These small red bumps are distinctive and respond well to simple interventions.
Prevention is key. Simple lifestyle adjustments can minimize sweating and keep pores clear, reducing risk significantly.
