In today’s digital era, the use of screens has become an inseparable part of daily life. From smartphones, computers, and televisions to various other smart devices, screens serve as the primary source of information, entertainment, and social interaction. However, excessive exposure to screens also brings negative impacts on mental health and cognitive functions. One of the solutions increasingly recommended by experts to overcome smartphone addiction is the practice of digital detox. This concept refers to a conscious effort to stop or limit the use of digital devices for a certain period. But what actually happens to the brain when someone completely disconnects from screens?
The Role of Dopamine in Smartphone Addiction
Dopamine is a neurotransmitter that plays a crucial role in the brain’s reward and motivation systems. Every time someone receives a notification, completes a game, or gets positive feedback on social media, the brain releases dopamine. This process creates a sense of pleasure that encourages repetitive behavior, causing users to unconsciously keep returning to their digital devices.
When someone undergoes a digital detox, dopamine production related to digital stimuli decreases significantly. At first, this may trigger withdrawal-like symptoms such as restlessness, boredom, and even anxiety. However, over time, dopamine levels stabilize. The brain becomes more sensitive to natural stimuli such as face-to-face interactions, reading books, or spending time outdoors.
The Impact of Digital Detox on Focus and Concentration
Continuous exposure to digital devices has been proven to impair a person’s ability to focus. A study by the University of California, Irvine, found that the average office worker can only maintain focus for about eleven minutes before being distracted by notifications or the urge to check their phone. Each distraction requires approximately twenty-three minutes for the brain to return to its original level of concentration.
Through digital detox, the brain is given the opportunity to restore its concentration ability, which has been disrupted by smartphone addiction. Without constant interruptions from notifications, the brain can once again enjoy activities that require deep focus, such as reading, writing, or completing complex tasks. Gradually, the brain’s capacity to maintain long periods of concentration will improve, leading to increased productivity.
Sensory Detox and Its Effects on the Nervous System
In addition to providing informational stimuli, digital screens also expose users to blue light, notification sounds, and rapidly changing visuals. All of these stimuli activate the sympathetic nervous system, which is responsible for the body’s fight-or-flight response, thereby increasing the risk of stress and anxiety.
A digital detox offers the brain and body a chance to undergo sensory detoxification. By reducing exposure to excessive stimuli, the parasympathetic nervous system responsible for relaxation becomes more dominant. The effects include a slower heart rate, improved sleep quality, reduced anxiety, and greater mental clarity. Research from the University of Sussex even found that just six minutes of reading a physical book can reduce stress levels by up to sixty-eight percent.
Long-Term Benefits for Mental and Cognitive Health
A digital detox is not merely a temporary break from technology but also a means to reset one’s relationship with digital devices. A brain no longer dependent on digital stimuli will find it easier to enjoy the present moment, delay instant gratification, and rediscover the joy of simple activities.
In the long term, this practice helps establish healthier habits, where technology use becomes more mindful and controlled. Individuals will be better equipped to filter information, manage their time wisely, and protect their mental health from excessive technological exposure.
Conclusion
Digital detox is not an anti-technology movement. Instead, it is an effort to regain control over how individuals interact with digital devices. Amidst the constant flow of information and distractions, taking time to fully disconnect from screens can be a simple yet highly impactful step toward better mental health, sharper focus, and a more balanced life.
