Extreme Heat: Human Metabolic Rates Soar at 104-122°F

Researchers have identified an upper critical temperature (UCT) for humans, likely between 104-122°F, which causes a rise in resting metabolic rate in hot and humid conditions. The study reveals significant differences in cardiovascular responses to heat between sexes, as well as variations across age and physical fitness levels. Understanding these temperature thresholds and individual variations can have implications for working conditions, sports, medicine, and international travel. Ongoing research is also investigating how heart function is affected by temperatures above the UCT.

The Critical Limit: Human Heat Tolerance vs. Climate Change

Scientists at the University of Roehampton have identified an upper critical limit for human heat tolerance, which is between 40 to 50°C (104 to 122°F). Resting metabolic rate plays a crucial role in determining this limit, as it can increase when individuals are exposed to sweltering conditions. Understanding this limit is important for establishing safe working conditions, especially as global temperatures continue to rise. The highest average global temperature on record was recently reached, with temperatures in some regions exceeding 50°C (122°F). Further research is being conducted to investigate the impact of high temperatures on heart health in different age and physical fitness groups.
