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.
The 35 degree temp was in ideal circumstances-in shade, with water to drink, unclothed, and at rest. A study I linked in another thread a while ago pointed out how these circumstances are almost never met, citing a heatwave in Russia in 2008 (iirc) that killed quite a few people, where the wet bulb temp never went above 28 degrees.
