Thermal comfort is a condition of mind, which expresses that one’s central body temperature is close to its optimal value. In addition to the purely physical aspect of temperature-regulation principles, we question here the existence of a social component to thermal comfort. Thirty-five adults performed first a scrambled-sentence test that included (or not) words suggesting social exclusion. Participants were then presented with a forced choice task for which they had to select a preferred color between two. Colors were selected as a function of three categories of thermal warmth. Results revealed that those individuals who were primed with social exclusion were more likely to choose warmer colors than those who had not received priming. These findings suggest that thermal comfort includes a social component that predicts our preferences for warmer environments, providing new guidelines for the social benefits of light-therapy and color interior design.
