Too Much Sitting

The best solution is to take frequent breaks where you move around, stretch, and exercise.

Wastage of time and energy

You Could Become Anti-Social or Depressed

With all of the possibilities available on a computer, it is easy to get obsessed to the point you become anti-social. For example, many online games (e.g., World of Warcraft) have been designed to be addictive and can easily consume so much time that you end up playing the game more than being around others. Others may find online shopping so beneficial that they rarely go out to shop.

For many, social networks can also be an escape of being social in the real world by doing most of your association with friends and family over social networks like Facebook. There have also been many studies that shows social network sites can be depressing because they only show all of the good, fun, and interesting things friends and family are doing. It can result in people believing that other people's lives are so much better than theirs.

Can Limit Learning and Create A Dependency

If you can remain focused, a computer with the Internet can be one of the greatest tools in history to learn about anything. It's also easy to become overly reliant on a computer and other electronic devices. For example, a spell checker is a great tool for finding spelling errors. However, if you never learn the proper spelling of a word and just rely on spell checker or auto-correct, you're more likely to make spelling errors.

Other tools like grammar checkers, GPS, and calculators are also extremely helpful. However, if you become too reliant on these tools, you may be helpless when they're not available.
