| Abstract |
This study was performed to evaluate sleep efficiencies and conditions for comfortable sleep based on the analysis of EEGs and MST under four thermals conditions. Five female subjects who have similar life cycle and sleep patterns were participated for the sleep experiment. Their age was from 20 to 22 years old. They were healthy, and had regular sleep with consistent bed and wakeup time. It was checked whether they had a good sleep before the night of experiment. Experiments were performed in an environmental chamber of 4.1×4.9×2.7m size. EEGs were obtained from C3-A2 and C4-A1 electrode sites. Sleep stages were classified, then TST, SWS latency and SWS/TST were calculated for the evaluation fo sleep efficiencies on thermal conditions. As results, it was concluded that indoor thermal en-vironments of 24∼26℃ was the best for comfortable and deep sleep. |
