Which condition is often mistaken for a sunburn due to its inflammatory nature?

Prickly heat, also known as heat rash, can easily be mistaken for a sunburn because both conditions exhibit redness and inflammation of the skin. Prickly heat occurs when sweat gets trapped in blocked pores, leading to irritation and an inflammatory response. The skin may appear red and inflamed, similar to the symptoms of a sunburn, which results from skin damage caused by ultraviolet (UV) radiation.

Unlike psoriasis and eczema, which have more distinct characteristics – such as well-defined patches or vesicles in the case of eczema – prickly heat manifests with tiny red spots and potentially a prickly sensation. Acne, on the other hand, presents with clogged pores leading to pimples, which is distinctly different from the hotter, itchier symptoms of prickly heat.

Thus, prickly heat’s inflammatory nature and appearance closely resemble that of a sunburn, making it a common source of confusion.
