Screens in the evening: why they spoil your child's nights
A cartoon right before bed, and suddenly falling asleep drags on. We explain why screens in the evening get in the way of sleep, and how to do things differently without a meltdown.
It is almost bedtime. You are getting dinner ready, tidying up with one hand, and to get five minutes of breathing space you put a cartoon on the tablet. It is calm, they are settled on the sofa, everyone can breathe. And then, when it is time to switch it off, it all kicks off, and once they are in bed they take forever to fall asleep. Sound familiar?
First things first: you have done nothing wrong. Every parent goes through this. The television in the evening, a video in your arms while you finish the washing up, that is real life, not a failing. Nobody keeps up a perfect evening every single day, and that is not the point here.
In this article, we look together at why screens right before bed make falling asleep harder, when it is best to switch them off, and above all what to replace them with so the evening stays gentle. Nothing extreme, just small steps you can try tonight.
What goes on in their head in front of a screen in the evening
When people talk about screens before bed, they often think screens tire the child out, so they should sleep better. It is the opposite. A screen right before bed keeps the brain awake and pushes back the moment when the body switches into night mode.
Two things are at play, and they add up. The first is the light coming out of the screen. The second is what they are watching, those fast images full of action that keep their attention on alert. We will take them one at a time, gently.
Screen light makes the brain think it is still daytime
The body uses light to work out when to sleep. In the evening, as the light fades, the brain understands that night is coming and gently prepares for sleep. It is an internal clock, and it runs on light.
A screen, on the other hand, shines brightly and from close up, often with a rather blue light. For a child’s brain, it is like a little sun thirty centimetres from their face. The message they get is “it is still daytime, no need to sleep”.
As a result, the sleep signal arrives later. The child ends up in bed, but their body is not ready to let go yet. They turn over, they call out, they ask for water, and falling asleep drags on. It is not a tantrum, it is their clock that has been delayed by the light.
The key point: screen light sends the signal “it is daytime” just at the moment when the body is trying to switch into night mode.
The content excites them and leaves the brain switched on
Light is not the only issue. What they watch counts just as much. A cartoon that moves fast, a game where they have to react, a video that runs one image straight into the next, all of it puts the brain into action. They follow along, they get excited, they want to know what happens next.
Yet to fall asleep, the opposite is needed: a brain that slows down, that gets a little bored, that is allowed to settle. After fast content, the child is still wired. Even if their body is tired, their head is still going at full speed.
You have probably seen it: they switch it off and they are more wound up than before, or on the contrary overexcited, as if they were on a little cloud. It is not bad will. Their brain has stayed switched on, and it takes time for it to come back down before they can drift into sleep.
How long before bedtime to switch off screens
The simple rule of thumb is about an hour. You switch screens off roughly an hour before bedtime, to give the brain time to find its calm again and the internal clock time to get back into night mode.
That last hour then becomes a gentle transition towards bedtime. No tablet, no television, you move on to quiet things. It is this moment that really sets up a good night, far more than the exact time at which they close their eyes.
And if an hour feels impossible on some evenings, that is not a problem. Start with what you can keep to, even thirty minutes, even a quarter of an hour. The aim is not perfection, it is to win a little calm before bed, evening after evening.
The key point: aiming for an hour with no screens before bed gives the brain time to come back down and get ready to sleep.
What to replace the evening screen with
The big question, once the screen is off, is “what do we do instead?”. Good news: the activities that calm the brain are often the simplest ones, and they are gentle moments to share. Here are a few that work well for a lot of families.
- A story read in a soft voice, snuggled up against you. It is the great classic, and it works because it slows everything down.
- A little drawing or some colouring, sitting quietly at the table while the light fades.
- A quiet game: a puzzle, some blocks, small figures, nothing that gets them excited or running about.
- A cuddle with nothing else going on, just being together for a moment before going up to bed.
- Talking about their day: what they enjoyed, what annoyed them. It clears the head and it brings you closer.
How to switch the screen off without a meltdown
The real issue, often, is not the screen itself, it is the moment when you switch it off. Cutting it dead, right in the middle of the video, with no warning, that is what sets off the tears. Here are a few things that help make that moment gentler.
- A clear rule, said in advance. Decide once and for all when the screen stops, and say it before you start it. “One episode, and then we switch off and go and read.” The child knows what to expect, and they do not feel betrayed when it stops.
- Give a warning a few minutes before. Two or three minutes before the end, slip in a quiet “we are switching off soon”. It avoids the abrupt stop. A child’s brain needs a moment to get ready to let go, exactly like ours.
- Replace it straight away with a ritual they love. You do not switch off into nothing. You move on at once to something nice: “we are switching off, and we are going to choose your story”. The child leaves the screen for another pleasure, not for nothing.
- Keep it the same every evening. Consistency does all the work. If the rule changes every evening, the child negotiates every evening. When it is always the same, it becomes a habit, and the meltdowns space out on their own as the days go by.
What if their bedroom stayed screen free?
One idea that helps a lot of families is keeping the bedroom as a screen free place. No tablet and no television in the room where they sleep. The bedroom becomes the place of calm and rest, and the brain learns to link it with sleep, not with excitement.
It also avoids the evening temptation, the “just one” video under the duvet that pushes back falling asleep without anyone noticing. When the screen stays in the living room, the bedroom keeps its role, and the move towards sleep happens more naturally.
That calm moment before sleep counts, and so does the comfort of the bed. A peaceful room, a soft light, and bedding that suits the child, it all goes in the same direction: helping their body relax. It is the whole thing that prepares a peaceful night, not one single act on its own.
Worth remembering
- Evening screens do not send the child to sleep, they keep their brain awake and delay falling asleep.
- Screen light makes the brain think it is still daytime, while the body is getting ready for night.
- Fast content, cartoons, games or videos, excites the child and leaves their head spinning for a while afterwards.
- Aim for about an hour with no screens before bed, and replace it with calm things: a story, drawing, a cuddle, a quiet game.
- To switch off without a meltdown: a clear rule said in advance, a reminder a few minutes before, a gentle ritual straight after, and the same thing every evening.
Frequently asked questions
How long before bedtime should screens be switched off?
The simple rule of thumb is about an hour before bed. That last hour with no screens gives the brain time to calm down and the internal clock time to get back into night mode. If an hour seems like too much, start with what you can keep to, even a quarter of an hour, and build it up little by little.
Why is my child wound up after a cartoon instead of being tired?
Because the screen keeps their brain in action. Fast images full of action excite them, and the light makes them think it is still daytime. Even if their body is tired, their head stays switched on. They need a spell of calm to come back down before they can fall asleep.
What can replace the screen right before bedtime?
With gentle things that slow the brain down: a story read against you, a little drawing, a puzzle or some blocks, a cuddle, or simply talking about their day. These are simple moments to share, and they prepare sleep far better than a video does.
How can I switch the screen off without it ending in a meltdown?
Announce the rule before starting the screen, one episode for example. Give a warning two or three minutes before the end, then move straight on to something they love, such as choosing their story. And above all, do the same every evening: consistency spaces out the meltdowns on its own.
Do I really have to take the television and the tablet out of their bedroom?
It is not compulsory, but it helps a lot. A screen free bedroom becomes the place of calm and rest, and the brain learns to link that place with sleep. It also avoids the “just one” video under the duvet, which pushes back falling asleep without you seeing it.
