Sweat gets a bad rap as an off-putting bodily substance, but without sweat and its evaporation that helps to chill human skin in hot weather we would experience more discomfort in that and similar conditions, says Konrad Rykaczewski, an associate professor in the School for Engineering of Matter, Transport and Energy, part of the Fulton Schools. Rykaczewski, a materials and thermal engineer, is among researchers studying the mechanics of sweat and it affects to help develop more effective cooling technology. He and other experts are examining sweat from is its micro to macro scales to gain an understanding of various ways people could better protect themselves from dangers of overheating and related health threats.
