I tend to have neck and back strains when I do not sit correctly in my chair. This happens because I have a bad habit of slouching when I am working on a project on the computer. This is one of the reasons I hurt my neck last week.
I was working on the CPA for Small Business website the weekend before last and I was slouching in my chair with my shoulders in a shrugged position. After several hours of this, I began to feel a pain in my neck and upper back. The next day I was in considerable pain because of the position I had been working in.
I’ve found that the best chairs for office work are those where the back and the seat are permanent attached at a 90 degree angle. This is opposed to the type of seat where the back is mounted on a spring and moves as you move against the seat back. These types of seats put a lot of strain on your back.
The best sitting posture for me is where I have both of my feet on the floor, my back is straight, and my arms and shoulders are in a relaxed position. I have also found that I am less fatigued when I take "stand up, stretch, and walk around" breaks every 45 minutes or so.
Over the last week, I have paid a lot of attention to how I sit at the computer. Today is the best I’ve felt in a week, and believe it or not, this afternoon I began to slouch while working on a spreadsheet. When I noticed I was doing this I had to remind myself to practice a good sitting posture.
