In a second study, firefighters were able to manage heat stress at temperatures reaching 45°C by reducing work output while their core temperatures stayed at 38.5°C.
Notes on verification
Directly corroborated by ABC News interview quote and underlying peer-reviewed Frontiers in Physiology study; minor rounding discrepancy in core temperature (38.65C vs 38.5C) is negligible.
