Perceived Cold and Skin Temperature as Functions of Stimulation Level and Duration.

摘要

Stimulation was a reduction of Delta H in the magnitude of heat flux irradiating subjects in cold air. For any constant duration, the terminal cold experienced grew as a power function of Delta H; the exponent ranged from 1.2 for the longest duration (30.9 sec) to 1.7 for the shortest (3.9 sec). For any constant Delta H, cold, unlike warmth, increased continuously and markedly with duration. Perceived cold at low, but not at high, levels of Delta H correlated strongly with changes in skin temperatures. (Author)
