Digital Skin Temperature and Biofeedback

Abstract

The present study simultaneously compared the skin temperature of the index and the little fingers during hand warming using biofeedback. There was a 5-min. baseline recording followed by a 10-min. session during which subjects attempted to increase skin temperature using the index finger with biofeedback in the form of lights and sound. Analysis showed no significant differences between the temperatures of the index and of the little fingers, but there was a significant increase in temperature during the session for both sites.
