Humans can't endure temperatures and humidities as high as previously thought
Penn State researchers found that the maximum wet-bulb temperature humans can endure is lower than previously thought — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.
