Tech Neck: What Your Screen Time Is Really Doing to Your Spine

If you work in Sydney's CBD, chances are you spend the better part of your day looking at a screen — whether that's a monitor, a laptop, or your phone between meetings. And while most of us accept some level of neck tightness as just part of desk life, there's a growing body of evidence suggesting that this kind of prolonged forward head posture is causing real, structural damage to our spines.

It even has a name now: tech neck.

What Exactly Is Tech Neck?

Tech neck refers to the strain and injury that develops in the neck and upper spine as a result of repeatedly bending the head forward to look at devices. It's not a single injury — it's a pattern of stress that accumulates over months and years.

Your head weighs roughly 5–6kg in a neutral position. But as it tilts forward, the effective load on your cervical spine increases dramatically. At a 15-degree forward tilt, you're effectively asking your neck to support around 12kg. At 45 degrees — which is about where most of us are when we look at our phones — that figure jumps to nearly 22kg.

Now imagine holding that position for several hours a day, five days a week. It's no wonder so many people come into our clinic in pain.

How Does It Show Up?

Tech neck doesn't always announce itself with a dramatic injury. More often, it creeps in gradually. Common signs include persistent aching or stiffness in the neck and upper shoulders, headaches that start at the base of the skull, a feeling of tightness or "knots" between the shoulder blades, occasional numbness or tingling into the arms, and pain that gets worse as the day goes on but improves with rest.

If any of that sounds familiar, your posture habits might be doing more damage than you realise.

What's Happening to the Spine?

Over time, the sustained forward load on the cervical spine can lead to changes in the natural curvature of the neck. The cervical spine is meant to have a gentle backward curve — and when that's lost through chronic poor posture, the discs between the vertebrae start to bear uneven pressure. This can lead to disc bulges, early degeneration, and irritation of the nerves running through the cervical spine, which is often what causes radiating pain, tingling, or weakness into the arms and hands.

What You Can Do Right Now

A few simple habits can significantly reduce the load on your neck: raise your screen to eye level, take a short break every 45–60 minutes to stretch, hold your phone up when scrolling, and be mindful of your posture during video calls. These adjustments won't undo existing damage overnight, but they'll stop the pattern from getting worse while you're being treated.
