The present invention provides: a cooling pillow which is easy to prepare, whose cooling capability lasts for a long time, which does not require a time-consuming operation such as changing the water, and which is effective in a hard-to-sleep summer night or when one has a fever from a cold; a cooling garment which has a reduced power consumption, allows one to avoid heat with a simple structure, and allows one to be comfortable even in a high temperature environment; and a cooling helmet capable of eliminating the discomfort caused by heat, preventing exhaustion of stamina, lowering of concentration, and lowering of work efficiency, and increasing the safety during work, etc. The above-described cooling pillow, the-cooling garment and the cooling helmet are all based on a principle that by allowing air to flow in close contact with a fibrous material which is in the vicinity of the body and contains a sufficient amount of water to promote vaporization of water so that the head, the trunk, etc., can be cooled by absorption of the vaporization heat thereupon. Accordingly, they comprise a fan for supplying air, a passageway for passing the air therethrough, a vaporization sheet defining the passageway and containing water, etc.

1. A cooling pillow, comprising: an air passageway serving as a path of air; a sheet-like water holding member provided on the air passageway for holding water with at least one side thereof which is in contact with the passageway being wet; air supply means for forcibly supplying air into the air passageway; and a water supply section for continuously supplying water to the water holding member by a water absorbing action of the water holding member, wherein a head which is rested on the water holding member directly or via a thermally conductive member is cooled by a vaporization heat which is absorbed upon vaporization of the water held in the water holding member into the air passing through the air passageway. 2. A cooling pillow according to claim 1, wherein the water holding member is detachably attached on the air passageway. 3. A cooling pillow according to claim 2, comprising control means for controlling an air supply capability of the air supply means.
