At what core body temperature does bathing in hot water become a risk for heat-related illness?

When core body temperature rises above about 40°C, bathing in hot water becomes a real risk for heat-related illness. Hot water transfers heat to the body quickly, and in water the body loses the ability to cool through sweating as effectively, so temperature can climb faster than the body's heat-dissipation mechanisms can keep up. Once the core temperature passes roughly 40°C, enzymes and brain function can start to fail, increasing the likelihood of heat stroke and other heat-related problems. So the threshold at which bathing becomes risky is over 40°C.
