I know there are millions of other people out there that are using thermal exposure for health, such as cold water immersion, dry sauna, hot tub or steam room. My watch has a Heat Acclimation calculation. Although I can't take my watch into the sauna (outside operating temps), it would be nice to be able to log thermal exposures in the app, and the icing on the cake would be that it would take these into account with heat acclimation calcs.
