Although the temperature of the arms, legs, and superficial areas (acral body parts) may vary greatly, the body maintains a relatively constant deep body (core) temperature. Substantial deviations from normal core body temperatures cause adverse effects ranging from minor annoyance to life-threatening illness. Although far less affected by temperature changes than the core, acral body parts can be adversely affected by cold temperatures, particularly if the exposure is prolonged or repeated.1
