Teenage insomnia: signs, causes, and support

Teenagers’ body clocks often shift later, while school schedules still require early mornings. Screens, late caffeine, irregular naps, worry, low mood, burnout, travel across time zones, pain, and an inconsistent routine can make sleep harder. Insomnia may show as taking a long time to settle, waking repeatedly, waking earlier than intended, or feeling unrefreshed. Daytime sleepiness and difficulty concentrating can follow, but those symptoms can also have other causes.

Keep wake time steady across the week and get outdoor light early in the day. Reserve the bed for sleep, reduce bright screens before bedtime, and avoid caffeine late in the day. If you are awake and frustrated, leave the bed briefly for a quiet activity in dim light, then return when sleepy. Keep naps short and earlier rather than using them to replace night sleep. Record sleep, mood, medicines, and substances for a clinician if the pattern continues.

Arrange an appointment when sleep difficulty continues, affects attendance or safety, or comes with persistent sadness, anxiety, panic, unusual energy, or daytime sleepiness. Seek urgent help for thoughts of self-harm, severe confusion, or dangerous behaviour linked to lack of sleep. A clinician can consider insomnia, depression, generalised anxiety disorder, burnout, jet lag, medicines, and other contributors.

Does my sleep pattern fit insomnia or a shifted body clock? Could mood, anxiety, caffeine, medicines, or another condition be involved? Which treatment is suitable for my age? What should I do after a sleepless night?
