Scientists have discovered new facts about sweat. Contrary to popular belief, sweat doesn’t form round drops on the skin. It spreads flat from tiny pores instead. The top skin layer, called the stratum corneum, acts like a sponge, absorbing sweat for about 14 minutes before the moisture forms a thin layer on the skin. Tiny hairs help carry sweat upward, allowing it to evaporate more efficiently. Researchers say these insights could lead to better sweat-resistant clothing, smarter wearable devices, and new cooling methods to help people stay comfortable during extremely hot weather.
