What should I do if I develop heat rash?

Prickly heat (miliaria) commonly affects not only children but also adults. In fact, its cause is quite straightforward: blocked skin pores lead to bacterial proliferation and subsequent infection. Since prickly heat is an inflammatory response, what should one do when it develops on the body?

What to Do When You Develop Prickly Heat

If you develop prickly heat, the first step is to improve the hot environment—ensure good indoor ventilation, as poor airflow can exacerbate stinging or burning sensations. Frequent bathing is essential to keep the skin clean and dry. Clothing should be loose-fitting, and garments must be changed and washed regularly. Avoid scratching or rubbing the affected areas to prevent secondary bacterial infection. Additionally, topical medications with cooling, astringent, and antipruritic properties—such as calamine lotion or prickly heat powder—may be used for treatment.

Individuals with prickly heat should avoid spicy foods—including alcohol, chili peppers, raw onions, ginger, and garlic—as these may intensify itching. Severe pruritus often leads to repeated scratching, increasing the risk of bacterial infection. Wearing loose clothing and maintaining well-ventilated living spaces are strongly recommended.

Moreover, if pruritus is especially severe, oral medications may be prescribed under a physician’s guidance. A light, bland diet is also advised. We hope this information proves helpful to you.
