Time -- Spending hours on the Internet may trigger depression, say researchers from Australia and China. Numerous studies have documented the link between mental illness and pathological Internet use, though the majority have found that excessive online behavior tends to occur as a result of conditions such as anxiety and depression, either as a way to self-medicate or as a manifestation of the person’s mental state. But what about the reverse? Could pathological Internet browsing lead to depression or other mental problems in people who are otherwise healthy?
