At a pediatric neurologist’s visit, three different complaints (headache, poor attention and fatigue) often come down to the same cause: sleep. Sleep is not the brain’s “downtime”; it is when memory is consolidated, growth hormone is released, and nerve cells are “cleaned.” In a child who does not sleep enough, migraine attacks become more frequent, ADHD symptoms get sharper, and in a child with epilepsy the risk of a seizure goes up. That is why sleep is asked about at every visit.
Sleep needs by age (per 24 hours)
| Age | Recommended sleep |
|---|---|
| 4–12 months | 12–16 hours (including naps) |
| 1–2 years | 11–14 hours |
| 3–5 years | 10–13 hours |
| 6–12 years | 9–12 hours |
| 13–18 years | 8–10 hours |
More important than the number is consistency: roughly the same bedtime and wake-up time every day, weekends included.
How screens affect sleep
The bright light of a screen in the evening delays the release of the sleep hormone, engaging content wakes the brain, and a phone in bed increases night waking. Studies of screens and headache are not clear-cut: in young adults, those with more screen time had a higher risk of migraine; in a pediatric headache clinic, total screen time did not depend on the type of headache, but in migraine with aura, more screen time was linked to more frequent attacks. The practical takeaway is the same: the screen itself is not the “enemy,” but it becomes a problem when it replaces sleep and breaks.
Simple rules at home
- No screens for an hour before bed; the phone does not stay in your child’s room overnight.
- Morning light: open the curtains after waking and, if you can, go outside for 10 minutes; this sets the body clock.
- Daytime activity: at least an hour of active play or sport; it makes falling asleep easier.
- An evening ritual: the same sequence, such as a bath, a book, lights out; 20–30 minutes in younger children.
- Screen breaks: a 5-minute break after 20–30 minutes, with eyes looking into the distance; long gaming sessions without breaks can trigger an attack in a child with migraine.
- Caffeine: energy drinks and cola disrupt teens’ sleep and make headaches worse.
Why teen sleep slides later
During puberty, the body clock shifts toward going to bed late and waking late. This is not laziness; it is physiology. The problem comes from early school start times: a teen is short on sleep on weekdays, sleeps until noon on weekends, and gets “jet lag” again on Monday. The solution: a weekend wake-up time no more than 1–2 hours different from weekdays, limited screens in the evening, and morning light and movement.
When to see a doctor
Snoring and pauses in breathing during sleep, frequent night waking, daytime sleepiness, odd movements or spells during sleep, more frequent night terrors, and headache and attention problems that continue despite a good routine. A sleep diary kept for 1–2 weeks is the most useful document to bring to the visit.
