A rise in body temperature as a result of passive heating is a potent stimulus for prolactin secretion (Christensen et al. 1985) and selective face-cooling (FC) is known to attenuate the prolactin response to hyperthermia (Brisson et al. 1991). However, there is some debate as to the role that skin temperature may play in modulating the perceptual and hormonal responses to heat stress. The aim of the current study was to investigate the prolactin response to heat stress where skin temperature is high and core temperature is low due to effective sweating, and the effect that FC would have. Sixteen, non heat-acclimatised human volunteers (11 male, age: 29
