Developed exclusively for Hammacher Schlemmer, this is the only head wrap that combines gentle compression and therapeutic heat to alleviate pain from stress and tension headaches. Its two built-in air bladders operate similar to hospital compression boots and use compression intervals to stimulate circulation by helping blood vessels expand and contract. A warming element provides heat therapy that relaxes tense muscles in the face and head. The corded remote allows one to select from three levels of compression and power the heating element. With 15 minute auto shut-off. Adjustable hook-and-loop fasteners ensure optimal fit. Polyester lining. AC plug.
