What Happens To Our Brains When We Use Too Much Technology?
How does digital media use the brain? What are the benefits of using a smartphone for personal productivity? Let's find out more about What Happens To Our Brains When We Use Too Much Technology?.

Thinning of the cerebral cortex, affecting memory and cognitive functions.
Excessive screen time in adults can lead to thinning of the cerebral cortex, the brain's outermost layer responsible for processing memory and cognitive functions such as decision-making and problem-solving, potentially harming learning, memory, and mental health. Research highlights the significant impact of prolonged screen exposure on the brain, not only in adults but also in children. Studies have shown that more than seven hours of daily screen time is associated with premature thinning of the cerebral cortex in children, which is correlated with lower crystallized intelligence and affects cognitive development. The findings from the Stanford Longevity Center emphasize the need for awareness and intervention to mitigate these negative effects on the brain's health and functionality, highlighting the importance of balancing screen time with other activities.
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 developing brain-related diseases such as dementia, stroke, or Parkinson's, due to its impact on learning, memory, and mental health, including the thinning of the cerebral cortex and reduced gray matter volume. For more comprehensive insights into the effects of screen time, the Stanford Center on Longevity provides valuable research and findings.
Hindrance to sleep due to delayed melatonin release.
Using too much technology before bed can significantly disrupt sleep patterns by delaying the release of melatonin. The light emitted from screen devices mimics that of daytime and suppresses the natural sleep signals, leading to desynchronization of the body clock and reduced deep sleep. Additionally, according to Sutter Health, the blue light from these screens continues to stimulate the brain, further suppressing melatonin production. As a result, this disruption can delay the transition to sleep, causing restless nights and potentially leading to other sleep-related health issues. Prioritizing a reduction in evening screen time might therefore be an essential step toward improving overall sleep quality.
Reduced gray matter volume, essential for daily human functioning.
Excessive screen time in adults can lead to reduced gray matter volume, which is essential for daily human functioning, including movement, memory, and emotions. This reduction is associated with impaired cognitive functions, such as learning, memory, and mental health, and may increase the risk of early neurodegeneration.

Alteration in brain structure and function, leading to cognitive impairments.
Excessive screen time has been linked to significant alterations in the brain, including thinning of the cerebral cortex and reduced gray matter volume, which can impair cognitive functions such as learning, memory, and decision-making. This phenomenon is detailed in a comprehensive study on the Longevity Institute at Stanford University website, where the implications of prolonged digital exposure are explored. Additionally, research highlights the detrimental effects on the frontal cortex, including impaired decision-making and impulse control, as well as shorter attention spans due to incessant digital distractions, pointing to the need for mindful management of screen time to preserve cognitive health.

Shorter attention spans and decreased working memory.
Excessive technology use can lead to shorter attention spans and decreased working memory, as it promotes overreliance on digital devices for information storage and retrieval, reducing the need for long-term memory recall and impairing cognitive functions such as attention and executive function. Prolonged exposure to screens and digital media can significantly impact attention spans, particularly in children and adults, by increasing excitability, displacing crucial learning opportunities, and inducing a greater desire for immediate satisfaction, all of which contribute to reduced attention and working memory capabilities.
Impaired decision-making and impulse control due to reduced activity in the prefrontal cortex.
Excessive screen time can impair decision-making and impulse control by reducing activity in the prefrontal cortex, the brain's outermost layer responsible for processing memory, cognitive functions, and executive decision-making, and may increase the risk of brain-related diseases such as dementia, stroke, or Parkinson's. According to research on how technology impacts the brain, chronic exposure to technology, particularly in teens, can weaken the prefrontal cortex, leading to impaired emotional processing, increased irritability, and difficulty concentrating. The constant loop of cortisol and dopamine exhausts the prefrontal cortex and disrupts the balance between reward and control systems in the brain. For more insights on this topic, you can explore how technology rewires the intricate circuitry of the teenage mind on the Epsilon Theory website.
Heightened attention-deficit symptoms and impaired emotional and social intelligence.
Excessive use of digital technology can lead to heightened attention-deficit symptoms, including increased distractibility and impulsivity, and can impair emotional and social intelligence by disrupting normal brain development and social interactions. This can result in symptoms such as technology addiction, social isolation, and disrupted sleep patterns. For more details on the effects of digital technology use, visit the National Library of Medicine website. Professionals are increasingly concerned about these impacts on mental health and overall well-being, prompting further research into mitigation strategies.
Chronic sensory overstimulation leading to memory and concentration problems.
Chronic sensory overstimulation from excessive screen time can result in significant memory and concentration issues. This constant bombardment of information and stimuli can overwhelm the brain, leading to impaired acquisition of recent and past memories, and structural alterations in gray and white matter volumes. As a consequence, there's an increased risk of developing cognitive, emotional, and behavioral disorders. The implications of such findings, as discussed in detail on Neuro Center NJ, highlight the importance of understanding the impact of digital device usage on mental health and neurological function.
Increased risk of internalizing problems such as depression, anxiety, and social anxiety.
Excessive screen time is increasingly linked to the risk of internalizing problems among youth, as it can disrupt brain development and escalate mental health issues such as depression and anxiety over time. The constant comparison with others online can further lead to feelings of depression and dependency. It is crucial for mental wellness to maintain a balanced approach to internet and social media use. For more insights on this topic, the Piedmont website highlights the detrimental effects of prolonged screen exposure, emphasizing the importance of managing and limiting screen time effectively.
