Surface and intradermal temperature responses of adults to ambient heat stress with and without cooling. [PDF]
Physiol RepAbstract Accurate measurement of skin temperature is crucial to understanding responses to heat. We tested the hypothesis that intradermal temperature would differ from skin surface temperature during ambient heating with and without fan and water spray (24°C).
