Just looking at someone who is probably very cold is enough to make your own body temperature drop a little, according to a new study in PLOS ONE led by Neil Harrison, a neuropsychiatrist at the Brighton and Sussex Medical School, because releasing a study on how to feel even colder seems super useful in the dead of winter. Cruelly, according to Harrison’s findings, the effect doesn’t work the other way around: Feeling cold is contagious but feeling warm is apparently not. (But that could be more about the study design — we will get to that.)
Harrison measured the temperatures of the right and left hands of 36 volunteers, and then made them watch a short video which showed one of four scenes: either an actor adding hot water from a steaming tea kettle into a transparent container filled with water, and then placing his right or left hand into the water; or an actor dumping ice from a plastic bag into the container and then placing a hand into the water. (Two additional, neutral scenes showed the actor’s right or left hand simply resting in the container of water.) In all of the videos, only the actor’s hand was shown, so the volunteers couldn’t see their facial reactions.
