A healthy 12-year-old is consistently getting only 7 hours of sleep per night. Based on the recommendations, which of the following is the most likely consequence of this sleep pattern?
- Difficulty concentrating and potential impact on academic performance. (correct)
- Experiencing a higher frequency of muscle twitches during sleep stages.
- Increased percentage of REM sleep to compensate for total sleep loss.
- A shift towards longer periods in Stage 3 sleep to maximize restfulness.

A sleep study reveals that a patient spends a significantly reduced amount of time in Stage 3 sleep compared to average. Which of the following physiological effects is most likely to be observed in this patient?
- Increased dreaming and vivid recall of dreams.
- Heightened muscle activity and frequent twitching during sleep.
- An extended period of light sleep with easy arousal.
- Compromised physical recovery and a weakened immune response. (correct)

Study Notes
- Recommended sleep hours for preschoolers (3-5 years): 11 to 13 hours.
- Recommended sleep hours for school-age children (5-10 years): 10 to 11 hours.
- Recommended sleep hours for adolescents (10-17 years): 8.5 to 9.25 hours with 25-30% REM sleep.
- Recommended sleep hours for adults, including elderly people: 7 to 9 hours with 20% or less REM sleep.
- Sleep consists of two basic stages: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM).
- NREM sleep consists of stages 1 through 3.
REM Sleep
- People begin the sleep cycle with a period of NREM sleep, followed by a short REM sleep.
- Dreams usually occur in the REM stage of sleep.
- REM sleep typically occurs 90 minutes after sleep onset.
- First period of REM usually lasts 10 minutes, with each recurring REM stage lengthening, and the final one lasting up to an hour.
- Intense dreaming occurs during REM sleep as a result of heightened brain activity.
- Paralysis occurs simultaneously in most voluntary muscle groups during REM sleep.
- The percentage of REM sleep is highest during infancy and early childhood.
- The percentage of REM sleep declines during adolescence and young adulthood.
NREM Sleep
- The NREM sleep period is made up of stages 1-3.
- Each stage can last from 5 to 15 minutes.
- Stage 1 is an awake state where the brain exhibits alpha waves having a frequency of 8-13 Hz.
- Stage 1 shows a reduction in activity between wakefulness and stage 1 sleep, and the eyes are closed.
