Detailed explanation-1: -The correct answer would be option A: spend more time in REM sleep and less time in NREM sleep.
Detailed explanation-2: -NREM sleep constitutes about 75 to 80 percent of total time spent in sleep, and REM sleep constitutes the remaining 20 to 25 percent. The average length of the first NREM-REM sleep cycle is 70 to 100 minutes. The second, and later, cycles are longer lasting-approximately 90 to 120 minutes (Carskadon and Dement, 2005).
Detailed explanation-3: -Research states that REM sleep takes up about 20% to 25% of total sleep time and happens every 90 to 120 minutes of a night’s sleep. A person may go through four to five cycles of REM sleep in one night, although longer periods of REM sleep are more likely to occur during the second half of the night.
Detailed explanation-4: -The first REM period is short, and, as the night progresses, longer periods of REM and decreased time in deep sleep (NREM) occur.
Detailed explanation-5: -Your heartbeat and breathing slow, and muscles relax even further. Your body temperature drops and eye movements stop. Brain wave activity slows but is marked by brief bursts of electrical activity. You spend more of your repeated sleep cycles in stage 2 sleep than in other sleep stages.
