Sitting position is important for your backbone:
- sit in firm chair witharmrests to relieve pressure in back and shouldres
- keep the upper back stright and shouldres relaxed .keep stmoach musscels pulled in, and maintain the proper curve in the lower back.tightenning the stomach and buttocks can do thais.some people are more comfortable sitting with the back of chair at a 10-15 degree angle. a small caushion behind the lower back maintains the natural curve to the back
- keep the knees slightly higher than hips. use a footstool under the feet if neccesary.
- don't sit for a long period of time.
- stand up every now and then so as to strectch light mussles and give them a chance to relax.
- In fact, sitting is harder on your back than standing. Why?
Most people think your backbone supports your body. It doesn’t. Your body actually supports your backbone. Your back’s 24 vertebrae and its jelly-like disks offer you flexibility, but not much strength. - Studies have proven that sitting in a properly adjusted chair that encourages motion reduces cumulative trauma disorders to nerves, tendons, and the neurovascular system.
- The goal is to continually allow your muscles and bones to find the most stable, most healthy position as easily as possible.
- Fact: the importance of office seating is underscored by the fact an office worker, throughout his career, spends 80,000 hours sitting in an office chair. Another reason why offices need seating that supports employees at all occupational levels.
- Their are uncertainties in ergonomics as in any other
science. But one point is not in dispute: that the human body is not structured
to sit in a chair all day!
