With the issue of extreme heat on players (and by default spectators too) does anyone use Wet Bulb Globe Temperatures to activate some sort of heat-relief activities at sporting events? Things like allowing water bottles in, setting up misting stations, etc.
Here is a little explainer that goes into WBGT for those not familiar. The big advantage is it better considers the heating impact of direct sunlight while also reducing the negatives when there's a good wind.
I've been in touch with a few colleges looking to use WBGT but we can't really find someone using it now with thresholds established.
