Along with this miracle of technological progress to the people and negative factors that affect health is not the best way. Those who spend on monitors, many hours of your life, don't always know what it is they face. However, the damage from the computer is, and it is quite significant.

The effects of electromagnetic radiation
Despite the fact that the age of the bulky, more like tube TVs monitors is long gone and in their place came a liquid crystal, any technology capable of affecting human health and the computer is no exception. All because around devices that runs on electricity creates an electromagnetic field. The radiation from a computer leads to the deterioration of blood supply of organs and tissues, reduced reproductive function and weakening the immune system. But most harmful radiation brings the nervous system.

Harm for children and adolescents
The harmful child is computer and how it affects nesformirovannost the child's psyche, researched for a long time. Even if an adult is sometimes not able to resist dependence on computer games then, what can we say about a teenager.

About the responsiveness, compassion and desire to help and can be no question – at present Computerman these qualities do not exist at all. They do not see the authority of the older generation, neither in parents, nor in the person of teachers. Their characteristics is an obsession, selfishness and indifference.
