A heating pad of the type having a particulate chemical mixture, which is exothermically reactive in the presence of air, and a pair of opposed panels forming an envelope containing the mixture and admitting air to support the reaction. Differing perforation sets in the opposed panels allows the pad to generate two levels of heat and allows opposed body-contact surfaces of the pad to apply two different heat conditions to the human body.
