Quizplus · Accepted Answer

REM rebound occurs when someone's body compensates for a lack of REM sleep by increasing the amount and intensity of REM sleep during subsequent sleep cycles. Therefore, if John did not sleep much last night, his body will try to catch up on REM sleep, causing him to experience REM rebound. A sleeping pill (A) or excessive caffeine consumption (B) can interfere with REM sleep, while sleeping more than 8 hours (D) may not necessarily result in REM rebound.
