: The paper presents the results of studying the impact of using cellular phones and personal computers on the health status of 277 Saratov schoolchildren (mean age 13.2 +/- 2.3 years). About 80% of the adolescents have been ascertained to use cellular phones and computers mainly for game purposes. The active users of cellular phones and computers show a high aggressiveness, anxiety, hostility, and social stress, low stress resistance, and susceptibility to arterial hypotension. The negative influence of cellular phones and computers on the schoolchildren's health increases with the increased duration and frequency of their use.
