Slowing of the heart rate caused by submersion in cold water.
Any signs and symptoms caused by the difference between the surrounding atmospheric pressure and the total gas pressure in various tissues, fluids, and cavities of the body.
Damage to tissues as the result of exposure to cold; frozen or partially frozen body parts are frostbitten.
A form of heat injury in which the body loses significant amounts of fluid and electrolytes because of heavy sweating; also called heat prostration or heat collapse.
A life-threatening condition of severe

The transfer of heat to colder objects in the environment by radiant energy, for example heat gain from a fire.
