Why Rainwater Sometimes Causes Itchy Skin

Rainwater feels fresh and pure, but many people notice itching, rashes, or dryness after getting drenched. Why does this happen?

🌧️ Reasons Behind Itchy Skin After Rain

1. Polluted Rainwater – By the time rain reaches the ground, it often mixes with dust, smoke, and pollutants in the air. This makes the water slightly acidic, irritating for sensitive skin.

2. Microorganisms – Stagnant rainwater puddles contain bacteria and fungi, which can stick to skin and cause infections.

3. Sudden Temperature Change – Cold rain on hot, sweaty skin may trigger itching or hives in some people.

4. Skin Barrier Damage – Already dry or sensitive skin reacts more aggressively to impure water.

🧴 What to Do After Getting Wet in Rain

• Take a quick shower with clean water to wash off pollutants.

• Use a gentle cleanser, not harsh soap.

• Pat skin dry (don’t rub).

• Apply a light moisturizer immediately to lock in hydration.

• If itching persists, a soothing lotion or calamine can help.

👉 If you notice persistent rashes, fungal patches, or boils after rains, consult a dermatologist.
