   How to sit in front of your PC

Studies carried out in the US in 1996 revealed that about 80 percent of computer workplaces are ready for rehabilitation. These studies also found out that an average computer user sits at his chair in front of the PC for the gigantic time of 80,000 office hours of his adult life.
Long hours of sitting in one posture is most traumatic for oneís spine. Any single upright posture for hours together makes the spine tense. Our spine has natural shape in the form 'S' the alphabet 'S'.

Office furniture often does not correctly support the lumbar vertebral column - the chair should fit along the spinal curve and not the other way round. But unforunately improperly designed chairs and bad sitting habits distort this natural S curve and puts the spine under lot of stress. As a result shoulders and neck are held tensely and get stiff through unnatural posture. The consequence: neck, back and head aches.
While putting in hours at the office desktop itíll pay to keep in mind the following:
You can avoid neck aches by placing monitor in a correct position.
Determine the optimal table height and place the monitor in a way that your eyes and the top of the screen form a horizontal line. The head should be just slightly bent, while the trunk should be held straight. The chair should be constructed in a way that it offers you as much free movement as possible. Do not stretch out your legs too far while sitting: instead maintain them at a right angle. Crossing your legs under the table is a big no-no. On one hand this posture increases the pressure on the sciatic nerve and on the other it reduces the blood circulation in the legs. 

     The healthy way to sit infront of your PC


The Shoulders should be relaxed.
The elbows should swing free.
Keep your wrists straight.
Pull your chin in to look down-donít flop your head forward.
Keep the hollow of the chair in the base of your spine.
Try leaning back in the chair.
Donít slouch or slump forward.
Alter your posture from time to time.
The distance between the monitor and your eyes should be about 60 cms.
