| Research Abstract |
The purpose of this study was to search an environmental condition we can maintain thermal balance during sleep.
We payd special attention to air velocity and sorts in summer, and to warming of the bed in winter.
The results are as follows.
1. In Summer, at ambient temperature 30ﾟC,exposure forehead or leg to a weak air current (0.4m/sec) intensified the degree of rectal temperature fall. Under this condition, the sweating was suppressed and body temperature was controlled mainly by dry heat loss.
2. An effective exposure site to air flow was the forehead in comparison with the leg to induce deep sleep. As for the sort of air flow, moreover, the cyclical flactuating air velocity was more effective for deep sleep without falling leg skin temperature than the uniformed air velocity.
3. In winter, warming the bed in advance facilitated the rise in leg skin temperature and deep sleep was maintained all night long.
