What sleep-related issue is highly prevalent in adolescence and affects mood and performance?

• A. Sleep deprivation due to late bedtimes and school start times
• B. Insomnia due to caffeine
• C. Sleepwalking
• D. Nightmares

Answer: (D)

In adolescence, a lot of sleep trouble comes from a mismatch between biology and daily schedules. Teens naturally shift toward wanting to sleep later, but early school start times force wake-ups that cut into the sleep they actually need. This creates chronic sleep debt. That ongoing lack of sleep is strongly linked to mood problems—irritability, mood swings, and higher risk for depressive symptoms—and to poorer daytime functioning, including reduced attention, memory, and overall academic performance. So, the issue most connected to mood and performance in teens is not a single-night problem like nightmares or a rare behavior like sleepwalking, but this widespread sleep deprivation resulting from late bedtimes paired with early school start times. Caffeine-related insomnia can contribute, but it doesn’t account for the pervasive pattern of insufficient sleep that many adolescents experience.
