These include:

*
issue of provocation of epileptic seizures;
*
problems associated with electromagnetic radiation;
*
vision problems;
*
problems with the muscles and joints.

In each of these cases the risk is directly proportional to time spent at the computer and its vicinity.

Provocation of epileptic seizures

Provocation of epileptic seizures opinion on the possibility of provoking attacks on the computer at work is greatly exaggerated. It is also not proven whether the computer can influence the course of epilepsy. However, there are some people sensitive to flashes of light and the possibility of the onset of epileptic seizures. If you have any concern about the appearance of a child attacks you need to go to a specialized medical center and study the brain during biocurrents flashes of light EEG (EEG) with photostimulation.

This study in most cases reveals disruption of brain cells (seizure activity) of people with epilepsy.

Electromagnetic radiation

Every device that produces or consumes energy, creates electromagnetic radiation. This radiation is concentrated around the device in the form of an electromagnetic field. Some devices, like a toaster or a refrigerator, create very low levels of electromagnetic radiation. Other devices (power lines, microwave, televisions, computer monitors) produce much higher levels of radiation.

You cannot see electromagnetic radiation, hear, smell, taste or touch it, but nevertheless it is present everywhere.
In fact, anyone familiar with the principle of a computer monitor (also known as video terminals and display) accepts the fact that there is no point in talking about the X-ray emission. A small amount of ionizing radiation produced by the cathode-ray tube inside the monitor effectively shield glass tube
