Social networks are dangerous for health, especially among children under 14, who spend more than 3 hours a day in the social networks, a new report at Tel-Aviv University states, Medlinks.ru informs.

As a result of the analyses of life of several hundred volunteers, researchers noted increase of psychotic signs among those people who spend extremely much time in Facebook and other social networks.

Among the disorders people suffer are the following: madness, concern, confusion, anxiety, and increased vulnerability. Also children who spend more than four hours a day suffer twice more from depression and three times more often have insomnia.

Another paradox is that social networks instead of connecting people rather stimulate their isolation.
