Everyone suffers with a bad back at some point in their life and if they don't they are incredibly lucky! Any one who works at a desk or sitting in an office chair all day will know how irritating back pain can be, it doesn't just affect you when in that position it then prevents you from doing so many things.
Some people will take pain killers and ignore the pain in the hope that it will go away by its self but this can just make it worse, pain killers will only hide the pain for a matter of hours.
Not many people will believe that bad posture can be prevented and fixed quite simply but it can.
A lot of people who suffer from this usually link it with their posture and the chair they use.
After correcting their posture and purchasing an office chair which supports this then the problem is usually solved with in a few weeks! You not only need a office chair which is comfortable but you also need one which improves posture.
You hear people say "you need to sit up straight" however this is just as bad as slouching, your spine isn't straight and never will be.
Your spine curves in at the bottom and out at the top, almost like a backwards "s" so you need a chair which promotes this.
Obviously sitting in any type of chair for a lengthy period of time isn't good for anyone.
If working at a desk you should always take short breaks even if it is just to stand up or walk for a few minutes this will help loosen the back up and prevent stiffness.
The back can stiffen and ache from any prolonged stance or position.
Movement is definitely a big factor in this.
From not only sitting in the wrong type chairs but also from suffering a bad back due to this, I definitely advise purchasing a good chair.
I know myself finding a posture improving office chair for a good price is hard, but I found one and my back is definitely improving.
After going through loads of different chairs at very expensive prices I now have a racing office chair, it's ergonomically designed adjustable back promotes posture and it's seriously improved my back.
I still make sure I have short breaks from sitting down through out the day to ensure my back doesn't become stiff.
