Individual Thermal and Behavioral Factors in Cold‐induced Vasodilatation

Abstract

Individuals were classified as fast and non‐vasodilators during a first hand‐cooling experience. They were then required to carry out a prolonged detection task in 80°F and in 55°F air temperature. Comparisons were made of bodily thermal characteristics during hand cooling and during the detection sessions and of the percentage and speed of detection. The results suggest the possibility of characteristic differences between the two classified groups as well as of a relationship between behavioral and thermal regulating mechanisms.

Digital Vasomotor Conditioning and Body Heat Regulation

“…As with a previous study (Teichner, 1966), the results indicate that /Ss who differ with regard to CIVD also differ in their thermoregulatory reactions to heat and cold. These data suggest that slow CIVD Ss tend to have a steeper thermal gradient in both conditions, i.e.…”

The effect of passive heating and head cooling on perception, cardiovascular function and cognitive performance in the heat

“…The mechanism underpinning this improvement in motor performance is likely to be an increase in general physiological arousal due to an activation of the thermoregulatory mechanisms (Teicher 1966;Hancock and Vasmatzidis, 2003). Reductions in motor performance in both animals and humans have been observed at much greater core body temperatures of C39.7°C in humans (Nielsen et al 1993;Galloway and Maughan 1997;González-Alonso et al 1999) and 39.8 to 42.5°C in animals (Caputa et al 1986;Fuller et al 1998;Walters et al 2003).…”
