Prickly heat is a type of heat rash that causes small pink bumps that itch and may have a “prickly” sensation. The rash occurs when the pores of sweat glands get clogged and often appears on areas that are covered by clothing, especially if there is friction. Prickly heat most commonly occurs on the chest, neck, and arms. Most common when it’s hot and humid, oils and ointments makes prickly heat more likely (and less likely to heal faster). Don’t avoid using sunscreen, but choose one that’s oil free and hypoallergenic. The first and most important step you should take to treat the rash is to get into cooler, dryer air. Gently cleanse the affected area. Try medicated acne pads for sensitive skin – the salicylic acid will help unclog pores. You can relieve itchiness with hydrocortisone cream (not ointment) and bath water treated with baking soda or an oatmeal product (Aveeno Bath Treatment). For severe prickly heat, you may even use an antihistamine, especially if you have trouble sleeping. With treatment, prickly heat should disappear within 2-3 days.
