My older son turned twelve last autumn. Around the same time, I started noticing something in the mirror behind him while he was sitting at the kitchen table doing homework on his tablet. His head wasn't really sitting on top of his shoulders anymore. It was drifting forward, like it was being pulled by a string attached to the screen.
I'm a physiotherapist. I've spent years looking at how people hold themselves, how children move, how adults compensate for years of bad habits. And here was my own kid, in my own kitchen, sliding into the exact posture I write articles warning grown adults about.
So I started paying attention. Not in a nagging way — I learned quickly that nagging doesn't fix posture, it just makes a twelve-year-old roll his eyes — but in a watchful, what-can-I-actually-do-about-this way. This article is what I've learned watching my two boys (and the teenagers in my callanetics classes, and the kids of friends I run with) navigate phones, tablets, and laptops without their necks falling off.
What "Tech Neck" Actually Means in a Developing Body
Tech neck is the catch-all term for the posture you see when someone is staring down at a device. The head tips forward. The chin juts. The upper back rounds. The shoulders curl inward. In adults, this is mostly a chronic loading problem — years of repetition shortening some muscles and lengthening others until standing up straight feels weird.
In teens and tweens, the picture is a bit different. Their bodies are still building themselves. Bones are lengthening, growth plates are open, and the muscles around the neck and shoulders are still figuring out their default tone. When a developing body spends hours a day in a single static position, the body doesn't fight it — it adapts to it. That adaptation is the part that worries me.
I wrote a longer piece on the actual mechanism behind forward head posture and why most people misunderstand what's happening. The short version: it isn't really the neck that's the problem. The neck is the visible part. The real issue is usually further down — in the upper back, the shoulder girdle, and the deep stabilizers that nobody thinks about.
What I Actually Watch For
I want to be honest. I'm not measuring my kids' craniovertebral angles in the living room. What I'm watching for is much simpler and any parent can do it.
The side profile while they're not paying attention
This is the most useful one. When my son is reading, watching something, or eating, I take a glance at his side profile. Where is his ear sitting in relation to his shoulder? Ideally the ear lobe sits roughly over the middle of the shoulder. If the ear is drifting forward — sometimes two or three centimetres ahead of where it should be — that's forward head posture settling in.
The key is to look when they don't know you're looking. The moment a teenager catches you assessing their posture, they will either straighten up dramatically or slump even harder out of spite. Neither tells you anything useful.
How they stand up from sitting
When my younger son gets up from the couch after a long stretch on his tablet, I watch the first few seconds. Does he stand up tall, or does he kind of stay folded for a beat before reluctantly unfolding? Kids whose upper back is getting stiff often have a delayed extension when they stand. It's like the spine has to remember how to stack itself.
Headaches and complaints they brush off
Both of my boys have mentioned headaches that they didn't connect to anything. "My head just hurts." Tension headaches at the base of the skull, especially after long screen sessions, are one of the earliest tells of tech neck in teenagers. The suboccipital muscles — the small ones right under the back of the skull — get loaded heavily when the head sits forward, and they refer pain right up into the temples and forehead.
Shoulder shrugging and neck rubbing
If your teen unconsciously rolls their shoulders, rubs the back of their neck, or cracks their neck repeatedly during the day, those are signals. The body is asking for movement and circulation in tissues that have been static too long.
Why I'm Not Panicking (And Why You Shouldn't Either)
Here's the part I want to be clear about, because the internet loves a good crisis narrative about kids and screens.
Posture is not destiny. A twelve-year-old who sits with rounded shoulders for an hour is not doomed to a hunched back at forty. Bodies are remarkably adaptable, and adolescent bodies are especially good at remodelling themselves once you give them the right inputs. What matters is the ratio — how much time spent in loaded, static positions versus how much time spent moving, loading the body in other ways, and giving the tissues a chance to reset.
My older son does a competitive sport. He runs, he climbs, he wrestles with his brother. He's outside more than he's inside. The hour he spends curled around a tablet in the evening is real, and worth addressing, but it's not the whole picture. If your teen is also active, plays a sport, walks to school, climbs trees on weekends — they have a lot of working capital in their favour.
The kids I worry about more are the ones who go from school chair to homework chair to gaming chair to couch, with no real movement in between. Even there, the fix isn't dramatic. It's just adding movement back in.
What Actually Helps (From Experiments at My House)
These are the things I've found genuinely move the needle. I've tried a lot of things that didn't work too, so I'll mention those at the end.
Raise the screen, not the kid
The single highest-leverage change I made was raising the screen. When my older son does homework on his laptop, it now sits on a stack of books with a separate keyboard. His head doesn't tip down because the screen is at eye level. For phones, I tell them: bring the phone up to your face, don't bring your face down to the phone. They forget. I remind them. It's a slow drip.
Time-bound, not screen-bound
I stopped trying to fight total screen time. I lost that war years ago, and most parents have. What I do enforce is position changes. Every thirty to forty-five minutes, the body has to do something different. Stand up, walk around, get a glass of water, go check on the dog. The break doesn't have to be long. It just has to break the static load.
A kitchen timer works better than any app for this in our house. I set one on the counter, and when it goes off, everyone moves. Including me.
Strengthen the back, not just stretch the front
A lot of advice about tech neck focuses on stretching tight chest muscles. That's fine, but it's not the whole story. The bigger issue in most teens I see is weakness in the muscles between the shoulder blades — the mid and lower trapezius, the rhomboids, the deep neck flexors. These are the muscles that hold the upper back upright against gravity. If they're weak, no amount of stretching the chest will keep the shoulders from rolling forward.
The exercises I give my boys are stupidly simple: wall angels (back against a wall, arms slide up and down like making a snow angel), prone Y-T-W lifts (lying on the stomach, lifting the arms in different shapes), and chin tucks (gently drawing the chin straight back, not down). Two or three minutes a day. That's it. Anything longer and they won't do it.
Get them outside
Honestly, this is the most underrated intervention. When my younger son spends a Saturday in the forest with my husband, climbing things and getting muddy, his posture for the rest of the weekend is visibly better. Varied movement — looking up at trees, reaching for branches, scrambling over rocks — does more for posture than any structured exercise. Deso takes them orienteering with him whenever he can. They complain about it sometimes but they always come back walking taller.
On Posture Correctors for Teens
Parents ask me about this a lot. Should I buy my teenager a posture corrector?
My honest answer: it depends what you want it to do.
A posture corrector won't fix posture on its own. No brace, no shirt, no gadget will permanently change how the body holds itself. What a good posture corrector can do is act as a tactile reminder — a cue that says "you're slouching" without a parent having to say it for the fifteenth time that day. For some teens, that reminder is genuinely useful. For others, it becomes a thing they wear that does nothing because they're still slumping inside it.
If your teen is motivated — if they've started caring about their posture, maybe because of a sport or because they noticed it in a photo — then a corrector worn for short periods during homework or studying can help reinforce the feel of a better position. The HYKLE SpineFlex Posture Corrector is the one I've recommended to a couple of friends with older teens, mostly because it's adjustable enough to fit smaller frames and isn't so bulky that a self-conscious fifteen-year-old refuses to wear it under a t-shirt.
But I want to be clear: the brace is a cue, not a cure. If you buy it and the strengthening exercises and the screen-height changes don't happen, the brace alone won't do much. I wrote more about how I think about back braces in general in this piece, which was aimed at adults but the logic applies.
For tweens under twelve or thirteen, I generally don't recommend a corrector. Their bodies are changing fast, they need to develop their own postural strength, and a passive support can become a crutch. Movement and strengthening are almost always the better intervention at that age.
What Didn't Work (At Least In My House)
A few things I tried that didn't help much:
Constant verbal reminders. "Sit up straight" said fifty times a day does nothing except make everyone resent each other. After about a week I gave up.
Posture-tracking apps and wearables. I tried one of those small devices that vibrates when you slouch. My son wore it for three days and then it disappeared into a drawer. Maybe it works for someone, but in my experience teens find them annoying and they don't address the underlying weakness.
Lectures about future damage. Telling a thirteen-year-old that they'll have neck pain at forty is roughly as effective as telling them they should eat more vegetables. The time horizon is too abstract.
Buying ergonomic chairs. I spent money on a "proper" desk chair for my older son. He sits on it sideways with one leg tucked under him. The chair is fine. The kid is the variable.
When to Actually Worry
Most tech neck in teens is a habit issue, not a medical one. But there are signs that deserve more than a parental eye-roll:
- Persistent neck pain that lasts more than a couple of weeks
- Headaches that are frequent and don't resolve with rest, movement, and hydration
- Numbness or tingling in the arms or hands
- A visible structural change, like one shoulder sitting noticeably higher than the other, or a side-bend in the spine
- Pain that wakes them up at night
Any of these and I'd want a proper assessment from a physiotherapist or a paediatrician. Scoliosis and other structural issues can show up around this age, and they're worth ruling out rather than assuming everything is just screen time.
The Long View
My older son's posture isn't perfect. Honestly, neither is mine, and I've been thinking about this for a living for over a decade. What I'm aiming for isn't perfection. It's awareness — that he knows what good posture feels like, that he has the strength to hold it when it matters, and that he understands his body well enough to notice when something is off.
The screen isn't going anywhere. My boys are going to spend more of their lives looking at screens than I did, and probably more than their kids will. The goal isn't to eliminate the screen. The goal is to build a body that can handle the screen without falling apart around it.
That happens in small daily decisions. Raising the laptop. Setting the timer. Throwing a ball outside before dinner. Doing two minutes of wall angels while the pasta water boils. Letting the body remember, every day, what it's actually supposed to feel like.
If you have a teen at home and you've been worrying about their posture, start with the side-profile check. Watch them when they don't know you're watching. Then pick one thing — just one — to change this week. Raise their screen. Or set a movement timer. Or take them on a Saturday walk somewhere with hills.
Small things, repeated. That's how bodies get built, and how they get rebuilt.
