PROBLEM TO BE SOLVED : To provide a heater/cold protector for warming a human body not from the surface of the body but from inside the body without using fuel or electric power.
SOLUTION : The nasal cavity-mounted heater/cold protector has an opened tube on the central nerve side, and a hollow heat storage tub made of paper, fabric or resin for temporarily storing exhalation heat discharged together with exhalation is disposed inside a heater/cold protector body at the center. The respiration resistance of the hollow heat storage tub is extremely low. The nasal cavity-mounted heater/cold protectors are set in nostrils on both sides without newly attaching a heat source to temporarily store the heat discharged together with exhalation in the hollow heat storage tub. The heat is re-absorbed and recycled at the time of exhalation to warm the human body. The somesthetic central nerve of the brain is warmed via the inner cavities of the human body such as nasal cavities, oral cavity and tracheae and through the lungs and pulmonary blood vessels, and the heart and neck artery in the deeper region, or warmed from the nasal cavities via the adjacent cerebral base. In this way, the actual heating and the sense of warming can be achieved by the device without using fuel or electric power.
