Sitting in a wrong posture on an office chair for prolonged intervals of time can undoubtedly trigger back pain or worsen an existing problem related to back and spine. The primary reason behind this is that sitting in a wrong posture, in an office chair increases stress within the back, shoulders, arms, and legs, and particularly, can add massive strain to the back muscular tissues and spinal discs.
A lot of people suffering with severe backache resort on painkillers and physiotherapy rather than focusing on how to improve sitting posture in office chair!
A correct sitting posture on computer or any desk can reduce the back pain minimizing the undue strain over back and spine.
How correct sitting posture reduces Back Pain
When you sit in an office chair for a long interval of time, the common tendency for most of the people is to stoop over or droop down in the chair, and this kind of posture can overstretch the spinal ligaments causing needless strain on the discs, muscular tissues and surrounding structures in the spine.
Over time, wrong sitting posture in the chair can damage spinal structures and contribute to or exacerbate a backache.
An ergonomic office chair is a tool that, when used in a right way, can help one maximize support to back and maintain correct sitting posture while working on a computer.
The first step in setting up an office chair is to ascertain the required height of the individual’s desk or computer or workstation. This choice is determined primarily by the type of work to be done and by the height of the person using the office chair.
The height of the desk or workstation itself can vary greatly and will require different positioning of the office chair, or a different type of ergonomic chair altogether.
Once the workstation has been situated, then the user can adjust the office chair according to his or her physical proportions.
Here are some important tips to help make sure that the office chair and workstation are as comfortable as possible and will cause the least amount of stress to the spine:
- Elbow measure: First, begin by sitting comfortably as close as possible to your workstation so that your upper arms are parallel to your spine. Rest your hands on your work surface (e.g. Desktop, computer keyboard) If your elbows are not at 90-degree angle, adjust your office chair height either up or down.
- Thigh measure: Check that you easily slide your fingers under your thigh at leading edge of the office chair. If it is too tight, you need to prop your feet up with an adjustable footrest. If you are extraordinarily tall and there is more than a finger width between your thigh and the chair, you need to raise the desk or work surface so that you can raise the height of your office chair.
- Calf measure: With your bottom pushed against the chair back, try to pass your clenched fist between the back of your calf and the front of your office chair. If you can’t do that easily, then the office chair is too deep. You will need to adjust the backrest forward, insert a low back support (such as a lumbar support cushion, a pillow or rolled up towel), or get a new office chair.
- Low Back support: Your bottom should be pressed against the back of your chair, and there should be a cushion that causes your lower back to arch slightly so that you don’t slump forward or slouch down in the chair is as you tire over time. This low back support in the office chair is essential to minimize the load on your back. Never slump or slouch forward in the office chair, as that places extra stress on structures in the low back, and in particular, on the lumbar discs.
- Resting eye level: Close your eyes while sitting comfortably with your head facing forward. Slowly open your eyes. Your gaze should be aimed at center of your computer screen. If your computer screen is higher or lower than your gaze, you need to either raise or lower it to reduce strain on the upper spine.
- Armrest: Adjust the armrest of the office chair so that it just slightly lifts your arms at the shoulders. Use of an armrest on your office chair is important to take some of the strain off your upper spine and shoulders, and it should make you less likely to slouch forward in your chair.
Rather than resorting on painkillers and physiotherapy improve your sitting posture in office chair, a correct sitting posture can heal your back pain.
