Background Vasoconstriction plays an important role in minimizing heat loss in cold temperatures. Because blood is shunted away from the periphery, changes in skin surface temperature (Tsk) gradients (forearm-to-finger and deltoid-to-hand) have been used as inexpensive and robust surrogate markers of vasoconstriction. The aim of this study was to compare dynamic Tsk gradient changes to a direct reference measure of blood flow (BF) in response to whole body cooling. Methods We acclimated 4 young participants (22.3 ± 1.0 years, 1 man) in standardized clothing (clo= 0.36) to a 28oC room for 30 minutes until Tsk achieved a steady state (
