"What effect does poor posture have on the body?"
Chapter. 1 Work Posture and Health
Physical problems at work
Poor posture creates repercussions on the eyes, neck, shoulders and lower back.
Approximately 70% of workers suffer from physical fatigue.
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.

5 things to know for ideal posture
Do you think sitting is a non-strenuous activity?
Chapter. 2 Good posture and body mechanics
5 things to know for ideal posture
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.

Chapter. 3 Changing your Work Posture
5 Work Postures Recommended by Okamura
It is important to change your posture to best suit the task at hand.
Writing a report, working on a computer, doing presentation in a meeting, talking on the phone…
There are various tasks performed in the office. To keep ideal posture in each situation, Okamura recommends five different postures. However, even the most ideal posture can only be maintained for approximately 30 minutes. In order to eliminate strain on your body, try to make a shift from one posture to the other, alternate between sitting and standing, take a break, and make a use of a chair and a desk, or support apparatus.
Chapter. 3 Changing your Work Posture
5 Work Postures Recommended by Okamura
Supports the creation of an ideal posture so that the spine forms a natural S curve.
Okamura pursues 3 points to ensure ideal posture.
1. Maintaining ideal posture
-
Adjust the seat to fit the body
-
Adjust the lumbar support to align to the S curve of the spine
-
Adjust the armrests according to arm length and task
2. Suitable distribution of body pressure
-
Requires a suitably firm cushion
-
Waist curve varies greatly with body type
-
Back curve adjustment mechanism improves the fit to the back
3. Adhering to posture changes
We have found a new pose called "low seat/backwards reclining" to enable long-term relaxation and maintenance of concentration.
The aim is the natural posture of zero gravity
Lowering the seat and reclining the chair back backwards stabilizes posture and reduces body stress
-
The body pressure applied to the bottom is reduced and dispersed on the seat and the chair back
-
Lowering the seat reduces swelling to the legs
Tilting the chair back and seat forwards creates an easy posture when using a computer.
Tilting the seat forward reduces pressure on the stomach
The number of people who continue to slump forward when using a computer is increasing. Tilting the seat forwards maintains the S curve of the spine by approaching the angle of the pelvis, thus reducing stress on the lower back/hips.
Because the chair back moves in concert with the seat, the upper torso is stable while working
The secret to efficient work is a mix of standing and sitting.
Similar to standing,
but less strenuous on the back
New idea:“ When I get tired of sitting, I can just stand up.”
Adjust the desk height according to the task
