Mood and sleep. II. Effects of aversive pre-sleep stimulation.

Abstract

To study the effect of an aversive film on subsequent sleep, 10 subjects slept in the sleep laboratory for two nights: one control night and one night after showing a color surgical movie. Only those subjects with higher tension scores on a self rating mood scale had a lowered number of sleep stage shifts, a higher percentage of stage 2 sleep and a higher number of waking periods and less sleep in the first 180 minutes after falling asleep.
