Abstract
A focal cooling apparatus includes a cooling, or heat sinking, layer over which a layer of compressible, thermally insulating material is disposed. The layer of compressible, thermally insulating material has a surface for supporting a portion of a human (or animal) body. The layer of compressible, thermally insulating material responds to pressure exerted against the surface by exhibiting a thermal resistance between the surface and the cooling layer that varies inversely with the pressure. Means are provided for maintaining the cooling layer at a predetermined temperature below normal human temperature.
