Question

Quizplus · Accepted Answer

REM rebound is when the body tries to make up for lost REM sleep. Therefore, if John did not sleep much last night (and presumably got less REM sleep than usual), he is more likely to experience REM rebound tonight. Taking a sleeping pill or drinking alcohol may disrupt his sleep cycle and decrease his REM sleep, while drinking caffeine could make it harder for him to fall asleep in the first place. Sleeping more than 8 hours may actually decrease the likelihood of REM rebound because the body has already had a sufficient amount of rest.
