For full body immersion in a hot whirlpool, the maximum allowable temperature is?

Explanation:
Full-body immersion in hot water stresses the body's cooling mechanisms, so there’s a practical upper limit to avoid hyperthermia. Keeping the water at about 104°F (40°C) provides therapeutic warmth—promoting relaxation and increased blood flow—while minimizing risk of overheating, dehydration, dizziness, or heat injury. Temperatures higher than this raise those risks significantly, which is why 104°F is the recommended maximum for full-body immersion. Slightly cooler temps can still be effective for comfort, but 110–112°F would be unsafe for full-body exposure. (Partial immersion allows higher temps, but that’s a different scenario.)
