Is sitting at a desk hard on your back,if you sit all day at work?!

Is sitting at a desk hard on your back,if you sit all day at work?

if you find that it is hard on your back there are a few things you can do to remedy the problem:
1- get a lumbar pillow and place it between you and the chair on your lumbar (lower back) region. lumbar pillows can be found at back / physical therapy shops or online, and range from $10-$20. or you can make your own. take a medium to large size towel (if it's large you may have to fold it in half twice, medium only once) then roll length wise and put rubber bands around it for it to keep it's shape.
2- stretches every hour or so try and stand up, raise your hands above your head while you bend back for a few seconds then to each side and then to front. these will help keep you from getting stiff.
3- keep yourself hydrated and not with coffee and cola. make sure you're drinking enough water for you (mean drink it but don't of do it). lack of water and too much coffee and cola can lead to muscle aches and kidney problems which will only make sitting at a desk 10x worse.

i hope these things help and and if you have any questions or comments feel free to shoot me a note.
