<p>  Supposing that use of the air mat would much contribute to keeping and promoting the healthy bodies of healthy people, specially health old people, too, therefore, we have examined the fundamental properties of the air mat and experimentally how much using the air mat would effectively affect the physiological mechanism of a human body.</p><p>  The results of our experiments mentioned above have made clear the following :</p><p>1. Many persons said that the most comfortable bedding was the futon ; on the other hand, however, other fairly many persons said that the air mats of wave-cell type or of separate cell type which were not so replete with air were comfortable.</p><p>2. The pressure applied to her body with an air mat when she was lying on it with her face directed upward was found gradually fluctuating within the range between approximately 10 and 120gf/cm2 ; however, the pressure applied to her body upon removal of the pressure was found below 40gf/cm2 in even such protruded parts of the body as the scapulas and sacrum, etc.. Although the magnitude of the pressure applied to the human body was found fairly different from each other in the measured parts thereof, it was found that the pressure had become the maximal in these parts such as the heels and the scapulas.</p><p>3. In case of using the futon, it was found that the pressure applied to the body was almost even in every part there of within the range between 20 and 80gf/cm2.</p><p>4. Although the temperature of the skin in the backside of the first foot's finger was found having somewhat gradually dropped as the time passed in both the cases of the futon and the air mat of wave-cell type, no remarkable differences were found between the beddings mentioned above.</p><p>5. The flow rate of blood in backside of the first foot's finger was found somewhat tending to drop as the time passed in both the cases of the futon and the air mat of wave-sell type ; however, the rate of its dropping was found much larger in case of using the futon than in case of using the air mat.</p>
