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, how to buy diflucan online pharmacy without prescription 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.
Acute kidney injury, which is defined as a sudden decline in kidney function, is a major cause of hospitalization during heat waves, especially in vulnerable populations such as older adults and obese individuals. This disorder is expected to worsen as the frequency, intensity and duration of heat waves expand in the U.S. due to climate change, according to study co-author Hayden Hess, Ph.D. As a result, there is concern the public health burden during these extreme hot weather events will be exacerbated.
The study was conducted in a group of adult men who were subjected to a heat- and humidity-controlled environmental chamber. The findings also indicate the risk of acute kidney injury was only evident when environmental conditions outpaced the ability of study participants to maintain core body temperature when cooling and hydrating were not permitted.
