Abstract
The effect of changing ambient temperature on skin temperature was recorded in human subjects; also, its effect on blood flow was measured using venous occlusion and optical plethysmography. When cold stimulus was removed in stages using a heating cabinet, it was found that a biphasic flow response occurred in the fingers with each step change in temperature. There was a rapid transient rise followed by a decline to an equilibrium flow level. The transient rise occurred even when the temperature rose from 37 to 40C, although at this level the equilibrium remained unchanged.
