An absorbent article that contains a warmth-providing substrate is provided that is capable of generating heat upon activation. Specifically, the substrate is coated with an exothermic composition that may be formed from a variety of different components, including oxidizable metals, carbon components, binders, electrolytic salts, and so forth. The oxidizable metal is capable of undergoing an exothermic, electrochemical reaction in the presence of oxygen and water to generate heat. In some cases, the exothermic composition is anhydrous, i.e., generally free of water, to reduce the likelihood of premature activation prior to use. |
