The safest and most foundational step — simply cooling and drying the skin resolves most mild cases.
How to do it ▾
Why it works: Cooling the skin and reducing sweat lets blocked sweat ducts clear and stops further irritation from trapped perspiration.
- Move to a cooler, well-ventilated space as soon as you notice symptoms.
- Remove damp clothing and let the affected skin air out.
- Change into light, loose cotton clothing.
- Repeat cooling breaks throughout hot days, especially during activity.
15-30 minutes per cooling break · Several times a day during hot weather
Caution: Heat rash can occasionally impair the skin's ability to sweat normally — stay in a cool environment until it clears. Watch for signs of heat exhaustion (dizziness, nausea, rapid heartbeat) if you've been in high heat for a long time.
When to get help: See a doctor if the rash doesn't improve in about 4 days, or if it looks infected with pus, spreading redness, or fever.

🌿 Overview
Hot, prickly skin sensations and tiny red bumps in summer heat — caused by sweat glands clogged by acidic skin conditions — relieved by alkaline baths, vitamin C, light cotton clothing, and cool air exposure.
Prickly heat (heat rash, miliaria) appears when sweat becomes trapped under the skin in hot, humid conditions — the tiny sweat ducts get blocked, and the trapped sweat causes clusters of small, prickly, itchy or stinging bumps. It favors areas that are covered, rub, or fold, and is especially common in babies and in hot weather.
The cure is simply to cool down and let the skin dry and breathe: moving to a cooler, airier place, wearing loose, light, breathable clothing, keeping the skin cool and dry, and avoiding heavy creams that block the pores. A cool shower or compressA cloth soaked in warm or cold liquid, held on the skin. How to make a compress → soothes the prickling, and the rash usually fades within a few days once the skin stops overheating. Prevention focuses on staying cool and dry in hot weather. Bumps that become very red, painful, or pus-filled, or come with fever, may have become infected and warrant medical attention.
Common signs
- Skin feels hot and prickly.
- Tiny red or pink, blister-like bumps that are extremely itchy — appearing on the chest, back, armpits, or creases of the elbows or groin.
- The condition usually resolves on its own in 3–4 days if the person stays cool and dry.
