Adolescents addicted to the internet should unplug

“Screenager” is a term often used to describe tech-savvy teens who irritate their parents with extended stints online. But is it more than that?

A new study from University College London found that increased internet addictions among adolescents may cause more serious health issues.

Researchers reviewed 12 studies involving adolescents ages 10 to 19 who had been clinically diagnosed with an internet addiction.

The studies used functional MRIs to track blood flow and evaluate how different regions of the brain interact. Adolescents were observed while resting and while completing a task, and the results were used to determine the effects of internet addiction on their behavior and development.

The researchers found there was a mix of activity in the parts of the brain engaged when resting. But there was an overall decrease in connectivity in parts of the brain involved in active thinking.

The study found that these changes led to addictive tendencies and behaviors in adolescents. Behavioral changes associated with mental health, motor coordination, intellectual ability, and development were also seen.

In an increasingly digitalized world, internet addiction might sound like a phrase made up by gripey parents who can’t get a screen-free meal with their offspring. But underdeveloped adolescent brains are especially vulnerable to external stimulation, and the consequences can be drastic.

While it may be unrealistic to quit the internet cold turkey, it’s a good idea think about occasionally pulling the plug.
