What Happens To Our Brains When We Use Technology Excessively
What is the relationship between digital media use and the brain? Do people who use their smartphones all day tend to have more problems with memory? Let's find out more about What Happens To Our Brains When We Use Technology Excessively.
Thinning of the cerebral cortex, affecting memory and cognitive functions
Excessive screen time in adults can lead to the thinning of the cerebral cortex, the brain's outermost layer responsible for processing memory and cognitive functions such as decision-making and problem-solving, and may also hinder learning, memory, and mental health. Studies have shown that children who spend extensive hours on screens exhibit premature thinning of the cerebral cortex, a condition linked to lower "crystalized" intelligence. This thinning not only impacts higher-order thinking and problem-solving but also affects emotional regulation. To explore these findings further, one can refer to the insights shared on the Stanford Center on Longevity where extensive research on this subject has been presented.
Increased risk of brain-related diseases like dementia, stroke, or Parkinson's
Excessive screen time in adults has been linked to an increased risk of brain-related diseases such as dementia, stroke, and Parkinson's, with studies indicating that more than two hours of screen time per day outside of work can lead to thinning of the cerebral cortex and higher risks of these conditions. Research from sources such as Stanford Lifestyle Medicine suggests that more than four hours of screen time per day is associated with an increased risk of vascular dementia, Alzheimer's disease, and all-cause dementia. This information highlights the potential long-term neurological impacts of excessive technology use, underscoring the importance of moderating screen exposure to protect cognitive health.
Disrupted sleep patterns
Excessive use of technology before bed is a prevalent issue that disrupts sleep patterns by suppressing the body's production of melatonin. The blue light emitted from screens is a primary factor in this disruption, leading to difficulties in falling asleep and poor overall sleep quality. Such nighttime use of technology not only impacts immediate sleep but also poses potential long-term health risks, including heart disease, diabetes, and depression. The suppression of melatonin and stimulation of the brain before bedtime can result in fragmented sleep and persistent daytime somnolence, negatively affecting cognition, memory, and mood. The Sleep Doctor highlights that reduced sleep quality and attentiveness the following day can be consequences, with serious long-term risks, such as obesity and certain cancers. Therefore, it is crucial to manage screen time, especially at night, to preserve health and maintain natural circadian rhythms.
Social isolation and impaired social intelligence
Excessive screen time in adults can have significant impacts on social skills, contributing to social isolation and impaired social intelligence. It diminishes valuable face-to-face interactions, which are crucial for developing empathy and the ability to recognize facial emotions. According to the insights shared on Stanford's Longevity Project, the effects are not limited to personal relationships but extend to broader social cognition issues. This digital overconsumption often leads to difficulties in understanding and interacting with others, further reducing empathy and the recognition of important social cues. Therefore, it is pivotal to balance digital use to maintain and enhance our social capabilities.
Heightened attention-deficit symptoms
Excessive screen time and technology use can lead to heightened attention-deficit symptoms, as it impairs cognitive functions and can result in increased distractibility and reduced attention span. Frequent digital technology use is also associated with impaired emotional and social intelligence, as well as technology addiction. These negative effects highlight the importance of being aware of one's digital habits. For more detailed insights on the consequences of digital technology use, a comprehensive study on the subject is available at Brain Health Consequences of Digital Technology Use, which thoroughly examines these phenomena and their implications on overall mental health.

Technology addiction similar to substance abuse addiction, affecting dopamine release
Excessive technology use can lead to a condition similar to substance abuse addiction, characterized by altered dopamine release pathways, reduced dopamine D2 receptor levels, and disrupted reward and emotion circuits, resulting in compulsive behavior and impaired cognitive control. This form of technology addiction triggers the release of dopamine, creating a dependency where the brain craves continuous dopamine release. This disruption of the brain's natural chemical balance negatively impacts impulse control, cognitive health, and overall well-being.

Impaired emotional intelligence and emotional regulation
Excessive screen time and technology use can impair emotional and social intelligence, leading to difficulties in emotional regulation, heightened attention-deficit symptoms, and increased risk of social isolation and mental health issues such as depression and anxiety. This is particularly concerning given that excessive screen time in adults can harm emotional regulation by affecting the brain's cognitive functions, including decision-making and problem-solving. Such effects can lead to increased risks of mental health issues, social isolation, and disrupted sleep. It is essential to understand the implications of these risks as highlighted in the research on What Excessive Screen Time Does to the Adult Brain. Addressing these issues is crucial to maintaining emotional well-being and preventing long-term adverse effects on mental health.
Reduced attention span and increased distraction
Excessive internet use can negatively affect cognitive functions, particularly attention and short-term memory, as the brain is trained to quickly shift focus between various tasks and notifications. This constant switching makes individuals more easily distractible and significantly reduces their ability to maintain focus on a single task for extended periods. In today's digital age, constant distractions from technology, including notifications and alerts, disrupt our focus and require about 23 minutes to fully refocus. This creates a cycle where we increasingly crave distractions, leading to a decline in attention span and exacerbating mental health issues such as anxiety and low self-esteem. Such challenges demonstrate the complex impact of digital environments on our cognitive wellbeing and mental health.
Dysregulation of cognitive control networks and reduced cognitive efficiency
Excessive technology use can lead to dysregulation of cognitive control networks, characterized by hyper-connectivity in the cognitive control network and default mode network, and hypo-connectivity in the visual attention network. This results in impaired attention, decision-making, and cognitive control. Moreover, excessive digital technology use can fundamentally alter brain structure and function, particularly affecting the prefrontal cortex and anterior cingulate cortex. These areas are crucial for executive functions like decision-making and cognitive control, leading to reduced cognitive efficiency and impaired self-control. The implications of these findings underscore the importance of understanding how digital technology interacts with our cognitive frameworks, which is elaborated further in the Frontiers in Cognition journal.
Increased impulsivity and poor decision-making capabilities
Excessive screen time can lead to increased impulsivity and poor decision-making capabilities due to its impact on brain structure and function, including the thinning of the cerebral cortex and a reduction in gray matter volume, which are crucial for cognitive functions such as decision-making and problem-solving. Repeated use of social media and other digital technologies can train the brain to adopt new behaviors and warped values. This can further exacerbate changes in brain function, particularly in areas related to emotional regulation and impulse control.
