To identify the effect of total sleep deprivation on sleep structures, polysomnography was performed for 8 healthy young adults. The subjects were young adults, ranging in age from 21 years to 26 years, with no past or present histories of significant medical, neurological, or psychiatric illness as well as no current major sleep disturbances or parasomnias, After one adaptation night, each subject was recorded polysomnography in the sleep laboratory. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales every 20 seconds, and tried paired-t-test.
The results were summarized as follows.
1. After on night of total sleep deprivation, compared with the baseline WASO was significantly decreased in the first recovery night, and SWS and REM sleep were significantly increased in the first recovery night.
2. Compared with the baseline, the relative value(％) of REM sleep was significantly increased in the nrst recovery night.
3. Compared with the baseline, TST was significantly increased in the first recovery night, and sleep latency and REM latency were significantly decreased in the first recovery night.
According to the above results we could identify the effects of total sleep deprivation on sleep structure in normal young adults.
