What the research tells us
Selective REM interruption was followed by increased emotional reactivity and a later rebound in REM percentage. This illustrates stage-specific rebound; it does not establish that extra total sleep completes emotional recovery.
Scope & interpretation
Small, male-only laboratory sample; repeated stimuli and differences between sleep manipulations limit generalisation. The study does not validate consumer-device REM estimates.
