Smartphones accompany us from the time we wake-up to until we fall asleep. These devices have evolved into an integral part of our lives, making it harder than ever to unplug. However, what if a brief pause could genuinely reset your brain?
A new investigation featured in Computers in Human Behavior has revealed that a brief hiatus from smartphones can genuinely alter brain chemistry. The researchers executed a trial involving young adults, instructing them to undertake a 72-hour smartphone detoxification process. Throughout this duration, participants were permitted to utilize their devices strictly for necessary functions such as work, performing daily tasks, and maintaining communication with immediate family or significant others.
During the span of these three days, the researchers carried out psychological assessments and employed functional magnetic resonance imaging (fMRI) to evaluate the consequences of diminished smartphone engagement. The brain imaging indicated significant changes in areas associated with reward and desire, displaying patterns similar to those seen in substance or alcohol addiction. [2]
A team from Heidelberg University and the University of Cologne in Germany conducted magnetic resonance imaging scans and psychological assessments prior to and following the phone diet to assess how this affected brain activity and neural patterns.
In this investigation, a group of 25 individuals between the ages of 18 and 30 who frequently used smartphones was chosen. Prior to a period of 72 hours without smartphone access, participants underwent evaluations to identify any issues related to their phone and gaming use, as well as any underlying mental health disorders. Before the initial brain imaging, they filled out surveys regarding their mood, smartphone usage, and urges. Following this, they were required to refrain from using their phones for a total of 72 hours. Post-restriction, fMRI imaging illustrated their brain activity in response to pictures of neutral environments, smartphones that were on, and those that were turned off. [1]
The brain imaging revealed that limiting smartphone usage resulted in alterations in regions associated with dopamine and serotonin, two neurotransmitters significantly involved in mood regulation, emotions, and addiction. Researchers noted that the effects of this smartphone limitation mirrored withdrawal symptoms akin to those experienced with addictive substances or cravings for food, impacting both heavy smartphone users and regular users alike. As technology advances, it is crucial to comprehend how smartphone practices influence brain functionality to establish more balanced digital habits.
Researchers continue to explore the impact of phones on our existence and cognition. It has been under two decades since the introduction of the first iPhone—but they have gained some insights into the subtle signs of withdrawal that occur when we refrain from using our devices frequently.
