As a parent, you\u2019ve had a sneaking suspicion that you child\u2019s heavy use of the Internet just can\u2019t be healthy. A new study, thought to be the first to examine the immediate\u00a0negative psychological impacts of Internet use, \u00a0has confirmed those suspicions. Researchers from Swansea and Milan Universities in Europe asked 60 volunteers, with an average age of 25, about their Internet use and whether they used\u00a0the Web obsessively or to the detriment of their social relationships and jobs. \u00a0The participants were then asked to surf the Web, visiting as many sites as they wished during a 15-minute window. After 15 minutes, they were analyzed for mood and anxiety. Those with a propensity for Internet addiction were found to have what drug addicts refer to as a \u201ccomedown\u201d when they come off a drug. \u201cWhen these people come off-line, they suffer increased negative moods\u2013just like people coming off illegal drugs like ecstasy,\u201d Professor Phil Reed of Swansea University said in a news release. \u201cThese initial results, and related studies of brain function, suggest that there are some nasty surprises lurking on the net for people\u2019s well-being.\u201d The study also claims that \u201cInternet addiction was associated with long-standing depression, impulsive nonconformity and autism traits.\u201d Meanwhile, \u201cInternet Use Disorder\u201d is now being added by the American Psychiatric Association to the May 2013 edition of their Diagnostic and Statistical Manual of Mental Health Disorders (DSM-V).\u00a0This means \u201caddiction\u201d will be officially applied to more than alcohol and other drug-related disorders.
