Corrected estimation of the risk of exertional heat illness based on the wet bulb globe temperature (WBGT) taking into account that WBGT underestimates heat stress under high humidity

Estimated risk	WBGT (°C)	Relative humidity (%)
Moderate	24	50
Moderate	20	75
Moderate	18	100
High	28	50
High	26	75
High	24	100
Excessive	33	50
Excessive	29	75
Excessive	28	100

Adapted from the categories proposed by Gonzalez¹⁸⁵ to estimate the risk of exertional heat illness during a marathon.
