Patent ID: 8807127

Claim:
A method of applying a steam-generating warming article, comprising: applying a steam-generating warming article to at least one part of a surface of a body, generating a cumulative amount a of released steam ranging from 0.5 to 12 mg during 3 hours after the application of the article per square centimeter of a steam release area of the article while said steam-generating warming article is in contact with the body, thereby supplying steam to the at least one part of a surface of a body, and maintaining a skin surface temperature at 38° to 49° C. over a period of from 3 to 15 hours, wherein said steam-generating warming article comprises a steam generating element which uses chemical energy and which supplies steam while in contact with the at least one part of a surface of a body, wherein the steam generating element uses an oxidation reaction of an oxidizable metal, wherein the steam-generating warming article comprises the steam generating element (i) having a heat generating sheet, wherein the heat generating sheet is a molded sheet including the oxidizable metal, a reaction accelerator, and a fibrous material, and (ii) having an incorporated aqueous electrolyte solution, and wherein the heat generating sheet generates heat upon contact with air, wherein the molded sheet comprises from 60% to 90% by weight of the oxidizable metal, from 5% to 25% by weight of the reaction accelerator, and from 5% to 35% by weight of the fibrous material, wherein the heat generating sheet comprises from 40 to 80 parts by weight of the aqueous electrolyte solution containing from 1% to 15% by weight of an electrolyte per 100 parts by weight of the molded sheet, wherein a weight ratio of the fibrous material to the oxidizable metal is from 0.1 to 0.3, and wherein a thickness of the molded sheet is form 0.15 to 1.5 mm.
