| Outline of Final Research Achievements |
The purpose of this study is to examine an analysis of the sleep after high concentration CO2-water bath in college students. Six healthy college students participated in this study. The subjects were attached to surface electrodes on their forehead to record an electroencephalogram (EEG). To measure the sleep-wake cycle, accelerometers (Lifecorder GS, SUZUKEN, Japan) was used. The sleep - wake data were analyzed by circadian rhythm analysis software (SleepSign Act, KISSEI COMTEC, Japan). The subjects were taken two different types of bathing; whole body immersion bathing and high concentration CO2-water bathing. The water temperature of both bathing was 38 degrees Celsius. Sleep is homeostatically controlled, and indeed, an increase in the NREM sleep is typically observed after CO2-water bathing in comparison to tap-water bathing. The sleep after the CO2-water bathing seems to be extremely useful in the physical recovery from fatigue.
