When the body loses heat faster than it can produce it, the core temperature falls below normal, leading to hypothermia. The body normally generates heat through metabolism and activity, but in very cold or wet conditions, heat is lost to the environment faster than it can be replaced. If exposure continues, body functions slow as the temperature drops, which can cause shivering, confusion, slowed speech, clumsiness, and eventually unconsciousness or failure of vital organs if not addressed.

Frostbite is about freezing of skin and underlying tissues in a specific area, not a whole-body temperature drop. Dehydration relates to fluid loss and doesn’t describe a systemic mismatch between heat loss and production. Heat exhaustion results from overheating and losing too much fluid in hot conditions, not from losing heat in a cold environment.
