Office work requires a lot of time of working at your office desk, and sitting in one of them for a long period of time can cause stress on your body which can result to injury and strains. The main reason is sitting in an office chair is a static posture that increases stress in the back shoulder, arms and legs. It can also add a large amount of pressure to the back muscles and spinal discs. Most people have the natural tendency to slouch over or slouch down in the chair, this posture can strain the discs and structure of the spine. This can only be prevented if you have a good office chair that can keep you comfortable and support you with a good posture.
Most office chairs nowadays are designed ergonomically that their sole purpose is for your maximum comfort. These type of chairs can be very expensive but will benefit you in the long run as these are not as expensive as having to maintain a damaged back. These ergonomic features of a good office chair is the main reason that prevents stress on your body.
How Ergonomic Office Chairs Work
Although sitting straight up while sitting on a chair is good posture this could put a lot of stress on your back this is why most ergonomic chairs usually tilt back when you lean on them to let you rest and reduce tiring your back muscle. The back rest should move independently so you can find a comfortable position.
Some office chair has footrest that lifts your knees to the same height of your hip joints this will help you maintain proper position. Having footrests can also reduce chance of developing circulatory conditions such as blood clots or varicose veins. People with shorter physiques will benefit from having footrest.
Another new feature of a good office chair is it has lumbar support, this support will allow you to fit your lower back’s natural curve. Lumbar muscles are vital to strength, rotation and flexibility in the body. So if you have low back pain, this pain will prevent you from being flexible and moving freely. Low back support also prevents you from slumping forward which can add extra stress on your lower back.
Many aches and pains in the upper back may result from the muscles of the upper back growing tired of supporting the weight of the arms. This is where the armrests support of your office chair comes in handy. Armrest support the weight of your arms and allow your neck and shoulder muscle to relax. Some people uses their wrists to support their arms when their chairs don’t have armrests which can also be stressful to your wrists. Please be careful though because these armrests are design to support your wrists when you stop typing and not while typing.
Using the resting eye level measure can also prevent neck strain from looking up or down in your monitor. This is how you do the test, close your eyes while sitting comfortably with your head facing front. Slowly open your eyes and aim your gaze at the center of your screen this should be within your eye level. If it is higher or lower then adjust the seat height of your chair by raising or lowering it. You should also do the elbow measure in which you measure by sitting comfortably as close as possible to your desk so that your upper arms are parallel to your spine. Rest your hands on your work surface and it should be at a 90-degree angle. If its not 90-degree you should either move your chair up or down.
