Poor posture creates repercussions on the eyes, neck, shoulders and lower back.
According to the Japanese Ministry of Health, Labor and Welfare, more than 68.6% of office workers are reported to be physically fatigued. Symptoms include eyestrain, neck and shoulder stiffness and back pain. These problems are said to be brought on by poor posture in the office where many of them spend around one-third or more of their day.
Sitting posture adds a tremendous amount of pressure to the back. The 100% body pressure on the lumbar intervertebral discs when standing increases to 140% when sitting, and 185% when hunched forward.
When sitting, the pelvis rotates backwards and the spinal s-curve is deformed. When people sit with bad posture for a long time, such as arching, hunching forward, perching on the edge of the seat and slumping, will put more pressure on your body.
How to improve sitting posture for a healthy back?
· Maintain normal S-curve and bend your knees at 90 degrees
· Make use of ergonomic chair and lumbar support to support your back
· Change posture every 1 hour, alternate between sitting and standing
· Stretch and exercise regularly
