What indicates heat exhaustion in a diver?

Heat exhaustion in a diver is indicated by profuse sweating. This condition occurs when the body loses an excessive amount of water and salt due to prolonged exposure to heat, leading the body to attempt to cool itself through sweating. As a diver is active in warm environments or experiences high levels of exertion, the body struggles to maintain its temperature balance.

While high temperature might serve as a sign of heat-related issues, it often becomes a more definitive indicator in scenarios of heat stroke rather than heat exhaustion. Pale skin and cold extremities are signs more indicative of shock or other medical conditions and not typically associated with heat exhaustion, which is characterized by active sweating as the body responds to heat stress.
