I was always taught to sit perfectly straight at a strict 90-degree angle, but it makes my lower back feel stiff as a board after an hour. Is there a better, healthier tilt angle I should be using instead?
Sitting at a rigid 90-degree posture is actually a myth that puts massive, unnecessary strain on your lower lumbar discs.
Ergonomic spinal studies show that a slight recline angle between 100 and 110 degrees is the absolute healthiest position for long-term computer work.
When you tilt back just a little bit, the office chair’s backrest takes over a significant portion of your upper body weight, which immediately unloads your lower back muscles, reduces pressure on your spine, and opens up your diaphragm for much better blood circulation throughout the day.
