Abstract: A cold massage tool. A closed tube of thin-walled heat-conductive material having one rounded end has an open end closed by a cap. A non-conductive heat-insulating tube open at both ends and shorter than the closed tube, encircles and tightly engages the closed tube from a point adjacent to the cap end and extending toward but well short of the rounded end, to provide a handle. A water-based material fills the closed tube. The water-based material can be frozen through a change-of-state condition by placing the tool in a freezing environment. It can thereafter be used to apply cold massage to a human body by bringing said rounded end into contact with a portion of the body, either directly or through a heat-conductive emollient gel. The contact may comprise gently massaging the gel-coated part in a continuous circular motion for five to seven minutes.
