Prickly heat / heat rash (ঘামাচি) happens when sweat ducts get blocked in hot, humid weather, trapping sweat under the skin. You get small itchy red bumps and a prickling feeling, usually on the back, chest, neck, folds and where clothes are tight. It is very common in Bangladesh summers.
How to treat it
- Cool the skin and reduce sweat — the core fix. Move to shade/AC, cool showers, loose clothing.
- Calamine lotion — dries the bumps and cools/soothes the itch.
- Keep the area dry — a dusting/cooling powder in folds helps absorb sweat.
- Do not scratch — it worsens irritation and can get infected.
- Most mild cases settle in a few days once you stop the sweating/heat.
Prevent it in summer
- Loose, breathable cotton clothes; change out of sweaty clothes fast.
- Shower after sweating; keep skin cool and dry.
- Avoid heavy creams and oils on the body in the heat (they trap sweat).
- Stay hydrated and out of peak sun. Pair with the summer routine.
See a doctor if…
Bumps turn into painful, pus-filled spots, spread, or do not settle — that can be a heat-rash infection needing treatment.
