Heat Rash (Prickly Heat)
Definition: Heat rash, also called miliaria or prickly heat, occurs when sweat gets trapped under the skin, causing small red bumps and itching.
Cause: Excessive sweating during hot, humid weather or sun exposure blocks sweat ducts.
Types:
- Miliaria Crystallina: Tiny, clear blisters filled with sweat.
- Miliaria Rubra: Red, itchy bumps that cause a prickly sensation.
Protection Before the Cause: - Wear loose, breathable clothing and stay in the shade or cool environments.
- Use talcum powder to absorb excess moisture and prevent clogging of sweat ducts.
Cure After the Cause: - Cool down by taking a shower or using cold compresses.
- Apply calamine lotion or hydrocortisone to soothe irritation.
- Stay hydrated to reduce the risk of heat rash.
Conclusion: Heat rash is a common but preventable condition, often resolved with proper cooling and skin care during hot weather.
