Which sleep pattern is common in late teens to early 20s and can affect functioning, especially with irregular schedules?

• A. Regular, consistent sleep schedule
• B. Irregular sleep schedules and insufficient sleep
• C. Sleeping more than 9 hours nightly
• D. Nocturnal schedule with daytime naps

Answer: (B)

Irregular sleep schedules with insufficient sleep are common in late adolescence and early adulthood, and they disrupt daytime functioning. When bedtimes and wake times swing a lot, the body's internal clock gets out of sync with daily obligations like classes, work, and social activities. At the same time, not getting enough sleep—especially on weekdays—builds up sleep debt. This combination makes it hard to stay alert, pay attention, remember things, and regulate mood during the day. The mismatch between when sleep is needed and when it actually happens is what most reliably leads to problems in functioning for this age group. Regular schedules or consistently long sleep can mitigate these issues, while patterns that focus on nocturnal activity with naps don’t capture the typical risk for daytime impairment as clearly.
