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 ba d summer night and when the user has the fever; cooling clothes consuming a lo w 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 decreas e of the attentiveness and working efficiency, and capable of improving the safety of work. The cooling pillow, cooling clothes and cooling helmet are a ll based on the principle that the air is made to flow in close contact with th e fibrous material being in the vicinity of the body of the user and containin g a sufficient amount of water, vaporization of water is promoted, and the hea d 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 containi ng water. |
