A steam heating mask having a mask body portion covering a nose and a mouth of a wearer when wearing the mask, a pair of ear hook portions provided at both left and right ends of the mask body portion, and a steam generator on the mask body portion, in which a proportion of an area occupied by the steam generator ranges from 30% to 80% with respect to an area of an entire surface of the mask body portion on a side of the wearer. The steam generator includes a first sheet on a surface of a steam generating portion on the side of the wearer with degree of air permeability being equal to or less than 7,000 sec/100 ml and a second sheet on a surface opposite to the surface of the steam generating portion with a degree of air permeability being greater than 8,000 sec/100 ml.

Steam heating mask

A heating implement () for body of the present embodiment includes a first sheet () having air-permeability; a second sheet (); a heating element (), intermediately arranged between the first sheet () and the second sheet () and containing an oxidizeable metal and a carbon component; and a first adhesive layer () and a second adhesive layer () provided in one of external surfaces of the first sheet () which is applied to a wearer side, in which a region without adhesive layer, in which none of the first adhesive layer () and the second adhesive layer () is disposed, is provided in at least a part of an external circumference section of the first sheet (), the following relations (a) and (b) are satisfied, and the heating implement is perfumed with a fragrance: (a) a mass ratio of a content of the fragrance to a content of the carbon component in the aforementioned heating implement (fragrance/carbon component) is equal to or higher than 0.2 and equal to or lower than 0.52; and (b) the content of the carbon component in the aforementioned heating implement is equal to or larger than 0.89 mg/cm.

Heating implement

A steam-generative warming devicehaving a steam generating elementthat releases steam in association with heat generation accompanying the oxidation of an oxidizable metal. The steam generative warming devicecontains a capsaicin analog and a menthol in a capsaicin analog/menthol mass ratio of 1/300 to 1/20000. It is preferred that the capsaicin analog be present in an element adapted to be brought into direct contact with the user's skin and the menthol be present in an element adapted not to be brought into contact with the user's skin.

Steam-generative warming device

A physiology enhancing device for improving physiological functions of a human body, etc., which comprises a heat generating element making use of chemical energy and a sheet interposed between the heat generating element and a body surface of a wearer, and which is designed to supply steam generated from the heat generating element while the device is applied to the body surface. The device exhibits steam generating capability for 2 hours or longer and, while applied to the body surface, raises the body surface temperature to a temperature from 38&#xb0; C. to lower than 42&#xb0; C. within one hour from the application. The sheet interposed between the heat generating element and the body surface preferably has a function of regulating air feed to the heat generating element and a function of transferring the heat of the physiology enhancing device to the body surface and preferably has a total thickness of 0.05 to 1.5 mm.
