A teen who cannot fall asleep early is not necessarily being difficult. During adolescence, the body clock tends to shift later, while school may still demand an early start. Add homework, activities, caffeine and a phone that never really goes to bed, and “just go to sleep” becomes an argument rather than a plan.
Begin with a shared goal
Choose a calm daytime moment and start with impact, not blame: “You have been exhausted getting up for school. What would make mornings less brutal?” The target is enough rest and safer functioning, not parental control over every minute.
For one week, let your teen track bedtime, estimated sleep time, wake time, naps, caffeine, evening screens and morning energy. Keep it private unless they choose to share details. Patterns are more useful than a lecture.
Anchor the wake time
A fairly stable wake time is the strongest practical starting point. Choose one that works for school and keep weekends within roughly an hour when possible. Sleeping until the afternoon can bring short-term relief but may push the next night later again.
After waking, open curtains and get bright morning light—outdoors when practical. Add movement and breakfast or another regular morning cue. These signals tell the body that the day has begun.
Shift the night gradually
- Start bedtime near the time sleep usually happens, not at an aspirational hour that creates long wakeful stretches.
- Move the wind-down and lights-out earlier by about 15 minutes every few nights.
- Keep the final half-hour low-key: shower, music, paper book, stretching or preparing for tomorrow.
- If sleep has not arrived after a while, get up for a quiet, dim-light activity and return when sleepy instead of scrolling in bed.
Check caffeine honestly. Coffee, tea, cola, energy drinks and some workout products can all delay sleep; stopping after lunch is a useful experiment. Avoid using alcohol, cannabis, antihistamines or unprescribed sleep products as sleep aids.
Make the phone plan practical
“No phone ever” is rarely collaborative. Agree on a device parking place outside the bed, a time for “do not disturb,” and exceptions for genuine needs. A basic alarm clock can remove the “I need my phone as an alarm” barrier. Parents should model the rule where possible.
If family media boundaries need a reset, use our family screen agreement template. For a broader look at whether screens are displacing sleep and other needs, see our whole-day approach to screen time.
Protect autonomy while keeping safety firm
Your teen can choose the wind-down activity, playlist and where the charger sits. Adults can hold limits around driving while sleepy, overnight gaming on school nights and caffeinated energy drinks late in the day. If a teen drives, make a no-questions-asked pickup plan for any time they feel too drowsy to drive safely.
When to seek help
Talk with a health professional if sleep difficulty persists, your teen cannot function at school, falls asleep unintentionally, snores loudly or gasps, has uncomfortable legs, or shows major changes in mood, anxiety or behavior. Seek urgent help for immediate safety concerns or thoughts of self-harm. Do not begin melatonin without a clinician; timing, dose, interactions and product quality matter.
A successful reset is not a perfectly obedient bedtime. It is a teen who understands the plan, gets more consistent rest and can adjust the routine without a nightly fight.
