Headache Causes: Prevent Headaches While Watching TV
Never watch television while lying down. The best position to watch television is sitting and your eyes should preferably be at the level of the television screen.
Do not sit too close to your television set. Take care to sit a considerable distance from the screen. It is easier for your eyes to focus on the images that flash across your TV screen. It is also less harmful for your eyes.
The ideal distance from your TV set is around five feet or more.
The room in which your television or computer is should be properly lit.
Watching television or working on the computer in the dark unnecessarily strains your eyes.
Make sure to always turn on a lamp or overhead light.
In the ideal condition, the light source should be behind you placed in such a way that the glare des not reflect on the screen.
