A cooling pillow capable of being prepared easily for the use thereof, maintaining the cooling capability for a long period of time, changing the water without taking much labor, and being effective when it is used at a bad summer night and when the user has the fever; cooling clothes consuming a low electric power, having a simple structure, and capable of avoiding the heat, and allowing the user to spend a pleasant time even in a high-temperature environment; and a cooling helmet capable of eliminating the unpleasantness due to the heat, preventing exhaustion of the physical strength, and decrease of the attentiveness and working efficiency, and capable of improving the safety of work. The cooling pillow, cooling clothes and cooling helmet are all based on the principle that the air is made to flow in close contact with the fibrous material being in the vicinity of the body of the user and containing a sufficient amount of water, vaporization of water is promoted, and the head or trunk is cooled by absorbing the heat of vaporization. These inventions therefore have an air sending fan, a flow passage through which the air is made to flow, and a vaporization sheet forming the flow passage and containing water. |
