Take care of your back
Make sure your chair is the right height and size for you and the desk you use．Your desk should be at about the same level as your elbows when you are sitting down．Chairs with armrests are good because they allow you to rest your arms．Do not lean forward over the keyboard towards the screen because this is bad for your back．Sit upright，with your feet touching the ground and your back resting on the back of the chair．Doing these things will help you prevent back-related problems such as pain in your neck，shoulders and arms．

Using a keyboard and a mouse can put pressure on your wrists and hands if it is not done properly．When you type，try to make sure your fingers are relaxed．You should hit the keys softly and hold the mouse gently．Mouse mats that come with soft material to support your wrist are really good too．Pain in the hands and wrists is very common among people who use computers a lot，so make sure you use your mouse and keyboard in the right way．
Take care of your eyes
Your eyes are very important and it is necessary to take care of them．You should give them regular breaks from staring at the computer screen．Every fifteen minutes，rest your eye muscles by looking away from the screen at something far away．Make sure that the top of your monitor is at eye level and that your monitor is about an arm's length away from you．
