spending more then 8 hours at your computer

Having a break every hour will be fine. But having more than 8 hours in front of your computer with out break will cause you something unhealthy. So have a break to rest your eyes, relax your body then you can spend more than 8 hours at your computer with out any unhealthy feelings or effects to your body.

That depends on you. Like me i do online money making stuffs. So i am required to spend at least 8 hrs a day on the pc. But that does not mean it is going to be bad. There are many things you can do. You can excercise and do your hobbies without any hinderance. People who say that staying more than 8hrs at computer is bad are directing it to towards gamers i guess.

hi.. Spending more time infront pc it may effect your health, batter take a rest after 1 hour or half an hour before back to your pc..

The thing is that if you spend hours and hours on a computer, you take sometime really to give your eyes some rest, I don't know if it's an old wives tale but really after staring in the monitor for so long, it's best to not get your eyes wet or something.. Just give the eyes some rest and don't stress it to much to maintain it's health, well that's what I do.
