Heat Balance in Restraint (Emotionally) Induced Hypothermia

Abstract

Hypothermia produced by restraint in the rat was shown to be due to an increased rate of heat loss (rather than to a decreased heat production) as a result of: a) a greater effective body surface exposure in the restrained rat as compared to the nonrestrained control animal (effective body surface exposure is that portion of the surface radiating to objects other than opposing areas of the animal's own body surface). b) A greater rate of heat loss per unit of effective body surface exposure in the restrained rat as compared to the nonrestrained control.
