You've probably heard it: "sitting is the new smoking." If you work long hours at a screen, that phrase is scary. What if your back was slowly wearing down without you noticing? Good news: science says otherwise.
The myth to forget
For a long time, people believed sitting crushed the spinal discs and directly caused back pain. That idea is now heavily nuanced by large recent studies. The verdict is clear: sitting itself does not cause back pain. It can produce temporary discomfort, but it doesn't "break" anything. Your spine is strong. Your discs are intelligent shock absorbers, designed to handle daily loads. A day at the office doesn't damage them.
Your spine is built to move.
What really matters: moving
The real problem isn't the chair. It's prolonged immobility. The human body loves movement. It needs it to circulate blood, mobilise joints, keep muscles awake. When we stay frozen for hours — sitting, standing, whatever — it protests. Science is very reassuring here: 30 to 60 minutes of movement a day is largely enough to offset hours spent at the desk. Brisk walking, cycling, stairs, gardening, swimming — it all counts. No gym required.
The golden rule: change position often
In modern physiotherapy we love this saying: "Your best posture is your next one." In other words, there is no "perfect" position to hold for hours. Your back needs variety, not rigidity. Slouched, upright, legs crossed, standing — alternate without guilt. Moving every 20-30 minutes is much more useful than searching for the "ideal" posture.
3 simple reflexes for your daily life
1. Stand up every 30 minutes. One minute standing, a few steps, a free stretch. 2. Move 30 minutes a day. The activity you enjoy is the best one. Consistency matters more than intensity. 3. Trust your back. It is stronger than you've been told.
When should you consult?
If pain lasts several weeks, hampers your daily activities, or comes with tingling, weakness or other unusual signs — don't wait. An assessment by a trained professional helps rule out what deserves attention and get you moving again quickly.
At Praxis Loten, in Eupen
Our team — physiotherapists, manual therapists and osteopaths — supports patients every day who believe their back is "fragile" or "worn out." Our approach holds in four words: Listen to your pain in its global context (sleep, stress, lifestyle). Relieve through adapted manual therapy. Strengthen through progressive personalised exercises. Explain how your back actually works. Our aim: that you leave stronger and calmer — not more worried.
