How much sleep does a teenager need?
Teenagers (14–17 years) are generally recommended to get 8–10 hours of sleep per night, per National Sleep Foundation guidelines.
Teenagers experience a natural shift toward later sleep and wake times (a delayed circadian rhythm), which often clashes with early school start times — a major source of teen sleep debt.
Example: waking up at 7:00 AM
8:15 PM
7 cycles · 10h 30m sleep
9:45 PM
6 cycles · 9h 0m sleep
11:15 PM
5 cycles · 7h 30m sleep
12:45 AM
4 cycles · 6h 0m sleep
2:15 AM
3 cycles · 4h 30m sleep
Example: going to bed at 10:30 PM
