"We stick the hand in a rigid chamber with an airtight seal around the wrist, and then we draw a bit of the air out of the chamber," he explains. "This causes blood to be pulled into the hand. Then we cool the overlying skin surface of the palm of the hand [by circulating cool water through a closed system on which the palm of the hand rests], which cools the blood in the hand's vascular heat-exchange structures. Arteries deliver blood directly from the heart to these vascular structures, and veins then carry the blood from these structures back to the heart." References will be given on request.
