How Reducing Phone Use Affects Brain Activity

A recent study has revealed that taking a short break from smartphone use can lead to significant changes in brain activity and help build healthier digital habits and lifestyles.

In the study, young participants were asked to undergo a 72-hour “digital detox,” during which they were only allowed to use their phones for essential purposes such as work, routine activities, or communicating with family and close partners.
During this “detox” period, researchers used functional magnetic resonance imaging (fMRI) to scan participants’ brain activity.

The results showed that smartphone deprivation led to noticeable changes in brain regions associated with reward and cravings, displaying patterns similar to those reported in drug or alcohol addiction.

The study involved 25 participants aged 18 to 30, who were assessed for problematic smartphone use and mental health conditions.
Before the study, participants completed pre-experiment questionnaires about their mood, phone usage habits, and cravings. After the 72-hour period, their brain responses to different stimuli were measured using fMRI scans.

Withdrawal Symptoms

Brain scans revealed activity in regions linked to dopamine and serotonin, two key chemicals responsible for regulating mood, emotion, and addiction.
This suggests that reducing smartphone use can cause withdrawal-like symptoms, similar to the effects experienced when quitting an addictive substance or experiencing intense food cravings.

Notably, this effect was observed in both heavy and moderate smartphone users, providing strong evidence of the impact of excessive phone use on brain function.
