🌿 Overview
Heat rash happens when sweat gets trapped under the skin on a hot, humid day. It shows up as little red or clear bumps that may sting or itch, often where clothes rub or skin folds. The fix is simple: cool the skin down, let it breathe, and keep it dry. Most heat rash clears on its own in a few days once you cool off.
Common signs
- Clusters of tiny red or clear bumps
- A prickly, stinging, or itchy feeling
- Mild redness on hot, sweaty areas
- Spots where clothing rubs or skin folds
- Relief once the skin cools and dries
