Which term describes going to bed early and waking early?

• A. Delated sleep phase syndrome
• B. Shift work sleep disorder
• C. Non-24hour sleep wake disorder
• D. Advanced sleep phase syndrome

Answer: (D)

Advanced Sleep Phase Syndrome is a circadian rhythm sleep-wake disorder where the clock shifts earlier, so sleep onset and awakening occur much earlier than desired. People fall asleep in the early evening and wake up in the pre-dawn hours, which can make it hard to stick with social or work schedules that require later hours. This pattern is especially common in older adults. By contrast, Delayed Sleep Phase Syndrome involves late bedtimes and late risings, Shift Work Sleep Disorder comes from irregular work hours, and Non-24-Hour Sleep-Wake Disorder involves a clock that doesn’t align with a 24-hour day. So the described pattern of going to bed and waking up early best fits advanced sleep phase syndrome.
