Oxygen comprises a heating element for generating heating and and water vapor being supplied, to provide a body-worn humidification body that can provide short time more water vapor to the skin.
Humidifying body 1 has a humidifying unit 11, the humidification unit 11, heating element 31 consisting of at least 15% of water by weight of the exothermic substrate and the heat-generating substrate comprising metal powder is provided. The skin side of the heating body 31 includes a cover sheet 32, the skin facing sheet 4 having a plurality of water vapor transmission holes 41 are provided. The garment side of the heating element 31 is provided with the non-skin facing sheet 5 of the air-impermeable and moisture-impermeable insulation layer 33. Water vapor generated by the heating element 31 is provided to the skin through the moisture vapor transmission hole 41 of the cover sheet 32 ​​and the skin-facing sheet 4. Water vapor transmission hole 41 has an average aperture diameter of a 0.2 to 2 mm, it is formed at 0.05 to 0.3 units a rate of per 1 cm ^2.
