1. Environmental Considerations: Heat
Thermal injury occurs when the body cannot produce enough heat loss to maintain a constant core temperature of 98.6°F. When the body cannot control core temperature, thermoregulation is lost and the end result can be heat exhaustion, heat stroke, or death. This chapter discusses the importance of maintaining equilibrium in hot and/or humid conditions, as well as responses to heat illnesses, hypernatremia, and hyponatremia.
