Working at a desk all day can be hard on the body. According to the American Chiropractic Association, low-back pain is the most common cause of job-related disability and missed work. One-half of all working Americans admit to having back pain symptoms each year.
Your back, which extends from the neck to the pelvis, supports the upper body’s weight and protects the spinal cord. The lumbar region (five lumbar vertebrae) makes up your lower back. 
Imagine your body is a tree, your back becomes the trunk and your spine (made of one spinal cord stacked on top of another) the roots. Each spinal cord contains nerves that carry messages from your brain to your body and vice versa. Your spine is responsible to help you move and feel all kind of sensations — hot, cold, sharp, pain, dull.
There are many causes to back pain, but one major contributor is our increasingly sedentary lifestyle. Prolonged period of sitting fatigues the muscles. Eventually, the lumbar won’t be able to maintain spinal alignment. In addition to doing simple stretches (you can do these exercises at your desk, see slideshow), invest in an ergonomic chair that offers spine support.
Things to look for in a good office chair include: lumbar back support, recline and adjustable seatback.
Are you ready for chair shopping? Here are the best office chairs for all budget.

- Container Store Bungee ($149)
Similar to CB2’s design, the Container store offers something similar for $50 less.
While work is important to our well-beings (read article) it certainly does not call for damage to back pain. What I am trying to get across to you is this: HEALTHY SPINE IS IMPORTANT.
Exercise, stretch, buy a chair. Capiche?
