The profuse sweating people experience in conditions of extreme heat — such as in Arizona’s desert climate — may be uncomfortable, but the salty sweat is a sign that nature’s way is at work to help protect our skin from those persistently hot conditions. The report links to a recent ASU News article looking at work led by Konrad Rykaczewski, an associate professor in the School for Engineering of Matter, Transport and Energy, part of the Fulton Schools, that explores  the biology of perspiration. One of the main goals for this research is to eventually find ways to help the human body be more comfortable on those 110-degree days. A wearable “heat suit” has been developed to aid the project.
