A recent study revealed that teens who spend most of their time watching tv have a higher risk of having depression when they grow up.
The more than 4,100 adolescents in the study were first asked in 1995 about the number of hours they had spent the previous week watching television or videocassettes, playing computer games, or listening to the radio. They reported an average daily exposure of about 5.7
hours, including 2.3 hours of television viewing.
Seven years later, at an average age of almost 22, 308 (7.4 percent) of the young people had developed symptoms consistent with depression. The incidence of those symptoms was directly related with the number of hours of exposure to television and other electronic media reported at the start of the study, the researchers noted.
However, “while we were able to control for a lot of variables such as socioeconomic status and education, in the final analysis we cannot be sure it was cause-and-effect,” researchers said.
It’s possible to speculate about why watching television might lead to depression, they said. “One theory is that you see a lot of depressing events on television and are likely to internalize them,” researchers said. “Television emphasizes bad news, and repeated exposure to it might be internalized.”
