Examination of Use of Heat-Exchange Equations for Determining Changes in Body Temperature

An experimental and theoretical study of heat transfer and temperature control in the dog

“…Hardy (1961) states that there is no good physiological evidence of this type of control action in temperature regulation, that is, a maintained displacement of deep body temperature from its normal level does not result in a progressive increase in the thermoregulatory re sponse. Hardy (1961) further points out that the biological temperature controller does not drive the temperature back into its neutral range during exposure to thermal loads, which rules out this type of control- Hardy (1961) does point out, however, that Wyndham et al (1952) found some nonlinearity in the sweating response to heat exposure when plotting sweat rate as a function of body temperature which might indicate some slight reset action.…”
