Why does my teenager stay up so late and struggle to wake?
Puberty really shifts the body clock later; a teen not sleepy before midnight is biology, not defiance, colliding with early school bells. Phones in bed and late caffeine then stretch a natural shift into true deprivation.
Teens need eight to ten hours. What helps: consistent wake times even weekends within reason, morning daylight, caffeine off by early afternoon, and chargers parked outside the bedroom overnight as a family rule that includes adults.
A teen sleeping enough hours yet always exhausted, or snoring loudly, deserves a medical look rather than a motivation lecture.

See a doctor promptly if
- Loud snoring with pauses in breathing, waking gasping, or falling asleep during the day despite time in bed. This suggests sleep apnea and needs assessment
- Falling asleep while driving or operating machinery, or any near-miss from sleepiness
- Acting out dreams, shouting, or physically moving during sleep
- Insomnia with low mood, loss of interest, or any thoughts of harming yourself
- New insomnia with weight loss, night sweats, palpitations or breathlessness lying flat
- Sudden loss of the need for sleep while feeling energetic and full of ideas. This needs prompt medical review
