Understanding Heat Rash: Causes and Symptoms
Heat rash, or miliaria, occurs when sweat ducts become blocked, trapping perspiration under the skin. This leads to tiny red bumps, itching, and a prickly sensation. It’s common in hot, humid weather or during intense physical activity. According to the NHS, infants and adults with sensitive skin are particularly prone to heat rash.
Types of Heat Rash
| Type | Appearance | Severity |
|---|---|---|
| Miliaria crystallina | Clear, fluid-filled bumps | Mild |
| Miliaria rubra | Red, inflamed bumps | Moderate (itchy) |
| Miliaria profunda | Flesh-colored, deeper lumps | Severe (rare) |
Best Treatments for Heat Rash
Cool, dry skin; loose clothing; calamine lotion; avoid scratching. Keeping the affected area dry is crucial—pat (don’t rub) with a soft towel after sweating. Over-the-counter remedies like 1% hydrocortisone cream or aloe vera gel can reduce inflammation. For persistent cases, a pharmacist may recommend antihistamines.
Home Remedies That Work
- Oatmeal baths: Soothe irritated skin with colloidal oatmeal.
- Cold compresses: Apply for 10-15 minutes to reduce swelling.
- Cornstarch or baking soda: Lightly dust on skin to absorb moisture.
Preventing Heat Rash
Wear breathable fabrics like cotton or moisture-wicking materials. Avoid heavy creams that block pores. The Cleveland Clinic suggests staying in shaded or air-conditioned areas during peak heat.
When to See a Doctor
If the rash spreads, oozes pus, or is accompanied by fever, consult a healthcare provider. These could indicate a bacterial infection requiring antibiotics.
