Technology Before Bed: What It’s Doing to Your Child’s Sleep
The issue of technology before bed for kids is genuinely important — not because screens are inherently evil, but because the timing of technology use has a specific and significant effect on sleep quality that most parents underestimate.
Here’s what’s actually happening, and what to do about it.
The Sleep Disruption Is Real
Screens emit blue light that suppresses melatonin production — the signal that tells the brain it’s time to sleep. This isn’t a minor effect. Significant screen use in the hour before bed can delay sleep onset by 30 to 60 minutes, and that delay compounds over a school week into a meaningful sleep debt.
Beyond the light, engaging content — particularly anything fast-moving, social, or emotionally activating — keeps the brain alert in a way that’s hard to wind down from. A child who’s been gaming or watching stimulating content for the hour before bed is not physiologically ready to sleep when the lights go out.
How Much Sleep Primary School Kids Actually Need
Children aged 6-12 generally need between 9 and 11 hours of sleep per night. Very few are getting that. When sleep is short-changed consistently, it affects mood, attention, impulse control, and learning in ways that look a lot like other problems — difficulty focusing, emotional dysregulation, difficulty at school.
If your child is struggling in any of these areas, sleep is always worth examining before you look elsewhere.
The Device Cutoff: How Early Is Early Enough
A good rule of thumb: no devices for at least an hour before bed. For a child who goes to sleep at 8:30, that means devices off by 7:30. For a 9pm bedtime, devices off at 8pm.
That timing is tighter than most families run, which is exactly why most families find their kids taking a long time to settle at night.
Build the Wind-Down Routine
The hour between device cutoff and sleep needs to be filled with something lower-stimulation. That’s not the same as boring — it can include reading, quiet play, a bath, a family conversation, a podcast, drawing, a board game. The key is that it’s less stimulating than what came before it.
A predictable wind-down routine — the same sequence every night — becomes a powerful sleep signal over time. The brain starts anticipating sleep when the routine starts, not when the lights go out.
Where Devices Sleep
Devices in the bedroom overnight are a problem even when they’re off. They’re a temptation, they disrupt sleep if they buzz or light up, and they’re the first thing a child reaches for when they wake at night or early in the morning.
A simple rule: devices charge in a central location, not in bedrooms. This removes the temptation and the disruption without requiring ongoing enforcement.
How to Introduce This Without a Revolt
If your family’s current pattern is screens right up until sleep, introducing a device cutoff will be resisted initially. Keep the introduction calm and clear: “We’re changing this because your sleep matters. Devices will stop at [time] from now on.” Hold it consistently through the first two weeks of resistance.
Most families find that within a week or two, their child is settling faster and waking more rested. That change is visible enough that it reinforces the rule.
Your Practical Takeaway
Tonight, move your child’s device to a charging point outside their bedroom before they go to sleep. Just that one change. See whether the settling is different when the device isn’t in the room. Most parents notice a difference within a few days.
