Slumping forward in a position common to laptop users stresses your lower spine at least 85 per cent more than standing. The chart illustrating A.L. Nachemson’s 1976 study on the difference in pressure ( as a percentage) on the discs of your lower spine in a variety of postures is still regarded as the definitive measure of the effects of postures and position on the disks of your lower spine. I love the updated version of Nachemson’s chart because it shows how great the inversion table is.
Don’t let your lower back and neck curve forward at the laptop. Raising the screen up to your eye level will have a positive impact on correcting your posture. Remember, a riser necessitates use of an external keyboard.
Sitting is the worst. If your lifestyle requires sitting long hours in front of a computer, get up frequently and move around.
I have been helping people to sit and move comfortably since 1998. I am always looking for ways to help people improve their relationships with their bodies.
