  1. In both the REMS group and the SWSS group, PSG data quality from one subject was not suitable for analysis in the habituation night.
  2. CTL control group with undisturbed sleep, REMS rapid eye movement sleep suppression group, SWSS slow wave sleep suppression group, TST total sleep time (time from sleep onset to morning awakening after the time awake during the night is subtracted), N1 sleep stage 1, N2 sleep stage 2, SWS sleep stage N3, REM rapid eye movement sleep, WASO wakefulness after sleep onset to morning awakening, M mean, SD standard deviation. p-values are uncorrected.
