Smartphone Detox: Here’s What Happens to Your Brain in Just 72 Hours!

Frank Herbert, an American science-fiction author, once stated:

Technology is both a tool for helping humans and for destroying them. This is the paradox of our times, which we're compelled to face.

One of the biggest examples of this paradox has to be the invention of smartphones, which have now become an integral part of our lives from the time we wake up to the time we sleep. How can we ignore the fact that its convenience has made our lives so effortless that we've become addicted to it? Now, imagine you have to stop using your phone and keep it aside for 3 days. You can only use your device for essential tasks like work, daily activities, and staying in touch with close family or partners. Seems like a far-fetched thought, right?

What is the research about?

Researchers from Heidelberg University and the University of Cologne in Germany researched Computers in Human Behaviour to investigate how cutting down smartphone use affects brain chemistry and asked 25 young adults, aged 18 to 30, to restrict their use of smartphones as much as possible for 72 hours. Before their initial brain scan, participants filled out questions about their moods, phone usage, and appetites. They then set a 72-hour ban on phone use.

How smartphones restriction transform your brain?

After the restriction, fMRI (functional magnetic resonance imaging ) scans analyzed the effects of reduced smartphone usage. The brain scans showed that restricting smartphone use had effects that were comparable to those of withdrawal from addictive substances such as alcohol or even food demands.

Reduced smartphone use was associated with alterations in brain regions related to dopamine and serotonin, chemicals that are important for mood, emotions, and addiction, according to brain scans.

Does digital detox work on young people?

Dr Shaunak Ajinkya, a psychiatrist at Kokilaben Dhirubhai Ambani Hospital, Mumbai, has tried this test on Akash, a 19-year-old college student, who was addicted to watching short reels on YouTube for six to eight hours daily, which was affecting his studies. He advised Akash to take up more physical activities and develop hobbies that require sustained focus. He stated:

Some participants initially experienced withdrawal symptoms, like restlessness and a compulsive urge to check their devices. However, after the first day, most reported feeling calmer and more present. The study showed that excessive smartphone use keeps the brain in a constant state of hyperarousal, contributing to chronic stress. Without this digital overload, our brains can relax.

This research highlights that digital detox is an important activity we should indulge in to keep ourselves mentally healthy and practice digital well-being. If cutting down smartphone usage even for a few days can make a difference in our brains, we should change our lifestyle and habits.
