Critical comment on the thermal entrainment of blood flow

Abstract

The blood flow variation observed in thermal entrainment experiments is not consistent with the blood flow variation observed in other experimental techniques for the study of thermoregulation. The inconsistency is resolved by demonstrating that the flow variations obtained during thermal entrainment experiments are primarily due to the sympathetic vasoconstrictive reflex. The reflex is elicited by the abrupt charges in the body's environment which the experimental procedure of thermal entrainment presently involves.
