is it harm??

Well I think it depends on what you do with other time you are not online.Like do you exercise any or work out.Well being on the computer for long time with out any brakes to strech your legs could cause eye problems with your eye being sore and make ya fat if you to not work out or have fast metatabilsm.

hello everyone...........I sit in front computer for more than 8 hour daily cause its my work and on weekday I work for 4 hour hours.....by doing this much surfing I had no problem.But this is not goo actually i have friend who work same as me but after some time he had complaint about his neck pain and eyes.He consult the Doctor and Doctor said its because he use computer that much.so my suggestion is that don't use computer for straight 3-4 hours just take a rest in the middle of the every work and try to sit very comfortably in front of your PC.

i probably use the internet longer than that everyday. well they say the complications could result in difficulties when socializing with people face to face. the quality of communication and dealing with people face to face goes down. thats what some studies say. i think it can be true. plus the lack in staying physically fit can go down. yikes!

Hi, Not at all.I am using my computer more than eight to ten hours a day.But haven't faced any health problem since.Make sure that your sitting position is comfortable.

if you sit more than 6 hours and miss the breakfast,or lunch or dinner.it will affect life.mainly can cause depression,ulcer and kidney problems. drink four liter water daily if you can. blink eyes regular and don't sit more than half hour continuously.if u use internet wisely you will not suffer. its fair to sit if you are doing earning on internet.if you play games for 4 hours hten its bad.

no that is not a problem, im on the net everyday for at least half the day.

I use my company at an average 9-12 hours a day 5 days a week, and usually 4 hours during my off. So far I don't any harm on it nor heard of someone who got complications in working in front of the computer most of the time. Just remember this suggestions. Make sure you are seated comfortable and in good posture while your working on your computer. Try to rest your eyes every 2-3 hours of straight work.

I sit in front of my PC more than 4 hours since it's my main work, computer data entry in the school, I guess there's no harm except in the eyes..

No it will not really harm you... maybe if you were straining your eyes looking at the screen you could damage your site at some point, but that is not always the case. I spend a lot longer on the internet than 4 hours, and it has not done me any harm.
