Heat Survivability Infographic (IMAGE)
Caption
Air temperature survival limits are greatly reduced in humid heat, and more so for older adults. The corresponding wet-bulb temperatures in dry weather are dramatically lower than the previously assumed limit of 95F or 35C. A wet bulb temperature of only 78F on a dry Phoenix summer day would be considered unsurvivable, yet it would take air temperatures of 128F under 10% relative humidity to reach that limit.
