Exposure to extreme heat (95 degrees Fahrenheit and above) and humidity for eight hours raises the core body temperature and causes dehydration, resulting in an increased risk of acute kidney injury, according to a new study. The researchers, from the Indiana University School of Public Health-Bloomington and University at Buffalo Center for Research and Education in Special Environments in New York, will present their findings virtually at the American Physiological Society’s (APS) annual meeting at Experimental Biology 2021.
