The study also found that teenagers who spent more time socialising with friends in real life or participating in team sports had a much lower risk for depression and suicide.
Although the rise in mental health issues in teenagers over recent years cannot be fully blamed on the growing use of smartphones, it is the strongest correlation that researchers have found so far.
To understand this further, a study by researchers at Korea University used magnetic resonance spectroscopy to scan the brains of teenagers that had been diagnosed with internet or smartphone addiction.
They found that the ratio of the neurotransmitter GABA, which is related to reward circuits in the brain, was different when compared to normal teenage brains. Reassuringly, when the teenagers went through cognitive behaviour therapy to help them with their addiction, their brain chemistry rewired back to look more like those of the non-addicted teenagers.
This hope that digital addiction is curable has resulted in the spreading of a new movement around digital wellness.
Software giants including Apple and Google have recently announced the release of new tools to help people to understand the extent of their smartphone addiction.
These dashboards offer a detailed breakdown of the time spent on smartphones each day and act as a fitness tracker.
Counting the number of times you unlock your phone, the number of notifications you receive and the amount of time you spend in each app they help people see how small, daily digital snacks can result in large amounts of time wasted over a week.
Built-in-timer options are available to throw you out of certain apps preventing you from binge-watching cat videos on YouTube or mindlessly scrolling through Instagram food photos.
So will digital well-being be the new health kick that we need to rest our overstimulated brains, or are we just building another app allowing the digital giants to collect data on how we use technology?
Only time will tell, but for now, I challenge you to try and go back to that powerful feeling of being truly bored. Who knows, you might even like it there and find yourself refining old-school skills such as the ability to daydream.
