High daily smartphone use does not automatically mean a person is addicted, according to psychiatrist and addiction expert Hendrik Peuskens of UPC KU Leuven, speaking on the Radio 1 program De wereld van Sofie. Modern mobile devices and software are specifically engineered to capture user attention continuously by tapping into natural brain chemistry, using targeted stimuli and dopamine pathways.
How Algorithms and Dopamine Target Attention
Technology companies design hardware, software, and app ecosystems to encourage automatic, continuous engagement. According to Peuskens, these systems exploit human neurology by focusing on what individuals find stimulating and enjoyable.
The neurotransmitter dopamine drives this process. Dopamine directs human attention toward rewarding and stimulating experiences. Apps and complex algorithms leverage this biological mechanism by delivering a constant stream of new stimuli, continually refining predictions to keep users engaged for longer periods.
Habit Versus Full-Scale Addiction
Peuskens draws a clear line between routine digital habits and chemical dependencies, such as alcohol or drug addictions. For most individuals, heavy smartphone usage stems from deeply ingrained habits and automatic behavioral patterns rather than a clinical addiction.
Problematic usage only emerges when a person loses control over their device habits, finds themselves unable to stop, or continues using apps despite clear negative consequences in their daily life. Simply logging high screen time numbers does not meet the clinical threshold for an addiction disorder.
Why a Dopamine Detox Falls Short
Popular internet trends like a “dopamine detox” do not offer a realistic fix for everyday digital over-reliance, according to Peuskens. Instead of drastic cleanses, users achieve better results by first tracking their actual screen time accurately and then intentionally scheduling offline moments throughout the day.
Pro Tip: Instead of cutting off your phone completely, look closely at your actual daily usage metrics and build intentional, device-free windows into your daily routine.
Furthermore, raw screen time totals fail to reveal the full picture of a person’s digital habits. “Not only the amount of time we spend on our smartphone is important, but also what we are actually doing there,” notes Peuskens.
Frequently Asked Questions
Does high screen time always mean you are addicted?
No. According to psychiatrist Hendrik Peuskens, high screen time usually reflects automatic habits and routines rather than a clinical addiction. Problematic use is defined by a loss of control and continued use despite negative consequences.
What role does dopamine play in smartphone use?
Dopamine is a neurotransmitter that directs attention toward rewarding stimuli. Apps and algorithms use constant new stimuli to trigger this system, keeping users engaged with their screens.
Are dopamine detoxes effective?
Peuskens states that a dopamine detox is not a miracle solution. A more effective approach involves reviewing actual screen time and intentionally setting aside device-free moments.
