Do sleep needs change during puberty according to melatonin shift?

• A. Yes, they increase
• B. Yes, they decrease
• C. No, they remain the same
• D. They become unpredictable

Answer: (C)

Puberty brings a shift in circadian timing due to later melatonin release, so teens naturally fall asleep later. The important point is that this shift affects when you sleep, not how much sleep you need. Most adolescents still require roughly 8–10 hours of sleep per night to feel rested and function well, similar to younger children. So although bedtimes shift and early wake times can create a mismatch, the amount of sleep needed remains the same; the challenge is meeting that sleep need within a schedule. It wouldn’t be accurate to say sleep needs increase or decrease, and saying they’re unpredictable isn’t the typical pattern—it's the timing that changes while the required amount stays about constant.
