Abstract
A steam-generating warming articlewhich has a steam generating elementmaking use of chemical energy and is adapted to supply steam while in contact with a human body. The article, while in contact with the body, maintains the skin surface temperature at 38° to 49° C. for 3 to 15 hours and cumulatively generates 0.5 to 12 mg/3 hr·cmof steam. The steam-generating warming articleis used to improve the human body's physiology. The steam generating elementis preferably a heat generating sheet prepared by incorporating an aqueous electrolyte solution into a molded sheet containing an oxidizable metal, a reaction accelerator, and a fibrous material.
