Key Points:
- Heat rash, also known as miliaria or prickly heat, occurs when sweat ducts become blocked, trapping sweat under the skin and causing red or clear itchy bumps, commonly appearing in areas with heat and friction.
- Triggers for heat rash include intense exercise, hot environments, tight synthetic clothing, and heavy skincare products, especially when winter skincare routines are continued into hot weather.
- Treatment involves cooling the skin with cold showers, compresses, air conditioning, wearing loose cotton or moisture-wicking clothing, and using over-the-counter hydrocortisone cream or calamine lotion to relieve itching.
- Avoid heavy moisturizers, petroleum jelly, scratching, exfoliating, and picking at the rash, as these can worsen the condition or lead to infection; facial heat rash requires gentler care and avoiding harsh skincare products.
- Prevent heat rash by wearing breathable clothing, changing out of sweaty clothes promptly, showering after heat exposure, and using talc-free powders or antimicrobial sprays to reduce moisture and inflammation.
