Wet-Bulb Heat: The Silent Danger

Wet-bulb temperature isn’t just about how hot it feels—it’s the real measure of how your body can cool itself through sweat. When humidity hits 100%, air temp and wet-bulb temp match, but in extreme cases, like Pakistan and Saudi Arabia in 2020, readings soared to 35°C—levels scientists once thought impossible. In the U.S., no major city has hit the dangerous 87°F wet-bulb mark yet, but many have flirted with the low 80s, already nearing the danger zone. Above 80°F, outdoor activity becomes risky; near 90°F, survival without AC or cooling becomes nearly impossible. This isn’t just discomfort—it’s a climate alarm bell.
