The CoolMitt circulates water at a temperature designed to avoid vasoconstriction in the palm, leveraging glabrous skin for cooling.

“And for that reason, Dr. Heller and some of his colleagues have developed a commercial product called the CoolMitt. You can actually go to their website, coolmitt.com. I don't have any financial or other relationship to them. I know they've been developing this technology for some period of time. It involves a glove that you put your hand into, it circulates water of a given temperature and it does so, and does so at a tempera or that is sure to not cause vasoconstriction of the palm.”
