Posture Poses Problems: Tech Neck, Forward Head Posture and the Effects of Bad Posture

By Bryce Milsom, Clinical Director, Evolve Physiotherapy

In this article: How modern screen use is driving an epidemic of tech neck and forward head posture, what the effects of bad posture are on your body over time, and what you can do about it.

Most of us spend hours each day looking at screens. Phones, laptops, tablets and desktop monitors have become central to how we work, communicate and relax. The physical cost of this shift is becoming increasingly clear. Poor posture, and in particular the forward head position associated with screen use, is now one of the most common contributors to neck pain, headaches and upper back problems that we see at Evolve Physiotherapy.

What is tech neck?

Tech neck is the term used to describe the neck pain, stiffness and discomfort that results from prolonged forward head posture during screen use. When you look down at a phone or lean toward a computer screen, your head moves forward of its natural position over your spine. For every inch your head moves forward, the effective load on your neck and upper back increases significantly. Over hours, days and years, this adds up.

Forward head posture is not just a cosmetic concern. It changes the way load is distributed through the cervical spine, places sustained stress on the muscles, joints and ligaments of the neck and upper back, and can contribute to headaches, shoulder pain, jaw tension and even reduced lung capacity over time.

The effects of bad posture over time

The effects of bad posture extend well beyond neck and back pain. Sustained poor alignment has been implicated in a wide range of conditions including cervicogenic headaches, shoulder impingement, arthritic changes to the spine, general fatigue, poor concentration and reduced organ function. The longer poor posture is maintained, the more ingrained the pattern becomes and the more effort is required to correct it.

Correcting posture that has developed over many years takes time and consistent effort. But it is entirely possible for most people, and even modest improvements in alignment can produce meaningful reductions in pain and fatigue.

A simple technique to correct your sitting posture

Rather than forcing your shoulders back, which is uncomfortable and unsustainable, try this technique that I use with patients at Evolve Physiotherapy:

1. Sit toward the front of your chair and allow yourself to slouch into the worst posture you can
2. Imagine a string tied around your lower back, coming out through your belly button
3. With your shoulders relaxed and your head looking forward, imagine someone gently pulling that string so your lower spine curves forward slightly
4. When you feel a gentle forward curve in your lower back, your entire spine will naturally follow into its optimal alignment
5. Avoid adjusting your head or shoulders separately as they will find their correct position automatically
6. Aim to hold this position for several minutes of every hour you spend sitting

This approach works from the base of the spine upward, which is the right way to correct posture. Forcing the shoulders back addresses the symptom rather than the cause.

What about phone and screen use?

For tech neck specifically, bringing your screen up to eye level rather than looking down is the single most effective habit change you can make. Holding your phone at eye level, using a laptop stand or adjusting your monitor height all reduce the degree of forward head posture during screen use. Combined with regular posture correction and targeted exercises, these changes can make a significant difference over time.

Getting professional support

If you are experiencing neck pain, headaches or upper back discomfort that may be related to your posture or screen habits, a physiotherapist can assess your alignment, identify what is contributing to your symptoms and develop a targeted plan to address them.

At Evolve Physiotherapy we assess and treat postural problems as part of our musculoskeletal physiotherapy service, and postural correction and core stability work also feature in our mobility and core rehabilitation classes.
