Sitting at a computer puts a lot of pressure on your neck and lower back. Knowing how to sit and when to move is the key to reducing or even preventing pain when sitting at your desk. So while there is no ideal way to sit – all sitting has a negative impact – when you have a neck or lower back problem some positions are better than others.
Set yourself up so that your feet are flat on the floor, your bum is at the back of the chair and with both your legs and back comfortably resting on the seat. Everything should be roughly 90 degrees. This puts you in an anatomically neutral position with the least amount pressure on your spine while sitting.
Once you feel the need to move, that is your cue to get up. It could take 5 minutes or 20 minutes, but when you start to feel uncomfortable in this position you must stand up. Take a walk or do some squats, just get off your bum and give your back a break!
