frostbite
|
|
|
Painful muscle spasms usually associated with vigorous activity in a hot environment.
|
heat cramps

|
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.
|
heat exhaustion
|
|
|
A life-threatening condition of severe hyperthermia caused by exposure to excessive natural or artificial heat, marked by warm, dry skin; severely altered mental status; and often irreversible coma

|
A continuation of an area of pain or discomfort distal to the site of the origin of the pain; gives the sensation that the pain is moving (radiating) away from the origin.
|
radiation
|
|
|
The loss of body heat as warm air in the lungs is exhaled into the atmosphere and cooler air is inhaled.
|
respiration
|
|
|
A system that delivers air to the mouth and lungs at various atmospheric pressures, increasing with the depth of the dive; stands for self-contained underwater breathing apparatus.
|
scuba
