Whilst the casual playing of computer games poses very little risk to health, it is important that players take regular breaks away from the screen in order to reduce the possibility of developing headaches, repetitive strain injuries or even deep vein thrombosis (DVT). Video games (and any other activity that produces flashes of light) may also trigger a pre-existing condition known as photosensitive epilepsy, which may cause seizures or blackouts. Again, limiting the length of time spent playing can help to reduce this risk, as can ensuring that the room is brightly lit and the player sits as far away from the screen as possible (at least 6 feet).
Whilst there is no neurological evidence that a player can become biologically addicted to playing computer games, some players may choose to engage in playing games more than any other activity. However, this is no different from an avid book reader or music lover who enjoys their hobby almost to the exclusion of all other leisure pursuits. So, in the same way as any other hobbies, playing computer games should be balanced with other interests, not only to reduce any health risks associated with long periods of play, but also to ensure a well-rounded and varied leisure time.
In this section, you can find out more about the health risks posed by playing computer games, along with safety issues such as TV damage caused by screen burn-in.
