Sit right, work pain-free

Office ergonomics and posture for desk professionals · By Dr. Vishwaraj Roy (PT)

The desk-job reality

The problem isn't sitting — it's sitting still, in the wrong position, for too long. The good news: small changes fix most of it.

What is ergonomics?

Ergonomics simply means fitting the job to your body, not your body to the job. Arrange your chair, desk and screen so your body stays in its natural, relaxed position instead of straining to fit the setup. Two ideas matter most:

Your spine is built for curves

Your spine has natural S-shaped curves at the neck, mid-back and lower back that cushion every movement, with discs between the bones acting as shock absorbers. Slouching flattens those curves and squeezes the discs unevenly — the front edge gets pinched, hour after hour.

Even load keeps discs cushioned; years of slouching create uneven pressure.

Good vs bad sitting posture

Reset cue: sit tall, drop your shoulders, tuck your chin — every time you sit down.

Set up your workstation once

ScreenTop of the screen at or just below eye level, about an arm's length (50–70 cm) away
HeadLook slightly down (15–20°) — never up, never craned forward
ArmsElbows bent 90–100°, forearms level, wrists straight
BackSit right back so the chair supports your lower back
LegsHips and knees around 90°, thighs level, feet flat or on a footrest

Five common desk mistakes

“Text neck”: why looking down hurts

Your head weighs roughly 5 kg when balanced over your shoulders. As it tips forward, the effective load on your neck climbs quickly — to around 27 kg at 60°.

Neck load at 0, 15, 30 and 60 degrees of head tilt: 5, 12, 18 and 27 kg
The fix: raise your screen, bring your phone up to eye level, and tuck your chin to stack your head over your shoulders.

From slouch to spondylosis

Cervical spondylosis is age-related wear and tear of the discs and joints of the neck, and it is very common after the 40s. Posture doesn't cause it on its own, but hours of forward-head strain can speed up the wear and bring on symptoms sooner — stiffness, aches and headaches. To protect your neck:

Motion is lotion

Movement pumps fluid to your discs and resets tired muscles, so break up stillness often.

Desk resets you can do now

Neck: chin tuck, ear-to-shoulder, and gentle neck rotation.

Chin tuck, ear-to-shoulder and neck rotation stretches

Back & shoulders: seated spinal twist, chest and shoulder-blade opener, and standing back extension.

How to: hold each stretch 15–20 seconds, breathe easy and stay gentle — never force or bounce. Do 2–3 rounds through the day.

Your daily desk-health checklist

This guide is general information, not a diagnosis. If you have pain that persists, spreads into an arm or leg, or comes with numbness or weakness, book an assessment. Motion Lab also offers workstation assessments and corporate wellness sessions.
