What Happens To Our Brains When We Use Technology Too Much?
How are computer-related technologies affecting the human brain? How is too much technology impacting the brain and Pavlov's theory? Let's find out more about What Happens To Our Brains When We Use Technology Too Much?.
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, and may also increase the risk of early neurodegeneration and other brain-related diseases. For more detailed insights on this subject, explore the comprehensive research on Excessive Screen Time Effects and understand how it impacts the brain's health and overall cognitive abilities.
Increased risk of brain-related diseases like dementia, stroke, or Parkinson's.
Excessive screen time among adults has been linked to an increased risk of brain-related diseases, including dementia, stroke, and Parkinson's, due to detrimental effects such as thinning of the cerebral cortex, reduced gray matter volume, and disrupted sleep patterns. Additionally, chronic sensory overstimulation from prolonged screen exposure can lead to impaired concentration and memory problems, increasing the risk of early neurodegeneration. This could potentially result in a significant rise in Alzheimer's disease and related dementias in later adulthood. For more information on the impact of screen time on the brain, you can explore further research on the Stanford Center on Longevity website.
Hindering of sleep due to delayed melatonin release from screen light.
Using technology before bed, especially screens that emit blue light, can significantly hinder sleep by delaying the release of melatonin, a hormone essential for inducing sleepiness. This exposure, particularly for two hours or more, can suppress melatonin production by about 22%, affecting the circadian system and leading to delayed bedtimes and poorer sleep quality. The stimulating nature of these devices can keep the brain awake, making it difficult to fall asleep. For more information about how Screens and Your Sleep are affected, consider the impact of nighttime usage and how it might be influencing your overall sleep patterns.
Reduction in gray matter volume, essential for daily human functioning.
Excessive screen time in adults can lead to a reduction in gray matter volume, which is essential for daily human functioning and is responsible for everything from movement to memory to emotions. To delve deeper into this subject, you can explore the implications on the adult brain at the Longevity Center at Stanford University. Understanding these effects is crucial, as gray matter plays a significant role in our cognitive and emotional well-being.
Alteration in brain structure and function, leading to cognitive impairments.
Excessive screen time in adults can lead to thinning of the cerebral cortex, reduced gray matter volume, and an increased risk of brain-related diseases such as dementia, stroke, and Parkinson's, as well as impairments in learning, memory, and mental health. Furthermore, the excessive use of digital technology can alter brain structure and function, resulting in reduced gray matter density in the frontal cortex, impaired decision-making and impulse control, and shorter attention spans due to the constant barrage of information and distractions.

Shorter attention spans and decreased working memory.
Excessive use of the internet and technology can lead to shorter attention spans and decreased working memory, as it trains the brain to quickly shift focus between multiple tasks, reducing the ability to maintain attention on a single topic for extended periods. Prolonged exposure to screens affects executive functions, particularly concentration and focus, making individuals more susceptible to distractions and compromising their ability to engage in long-term tasks. This is especially evident in young children and can persist into adulthood. For further reading on how these changes manifest in different age groups, visit the Wexner Medical Center blog, which explores the implications of technology on our cognitive abilities.
Impaired decision-making and impulse control due to reduced activity in the prefrontal cortex.
Excessive technology use, particularly smartphone addiction, can impair decision-making and impulse control by affecting the prefrontal cortex. Individuals prone to smartphone addiction tend to make riskier choices, exhibit poor impulse control, and favor immediate rewards over long-term outcomes, due to diminished activity and altered neural responses in the Prefrontal Cortex.
Heightened attention-deficit symptoms and impaired emotional and social intelligence.
Excessive technology use can lead to heightened attention-deficit symptoms, such as impulsivity, hyperactivity, and difficulty concentrating, as well as impair emotional and social intelligence, including disrupted emotional regulation, decreased empathy, and impaired social skills. For an in-depth exploration of these impacts, you can visit this insightful Escholarship resource.
Chronic sensory overstimulation leading to memory and concentration problems.
Chronic sensory overstimulation from excessive screen time can lead to various cognitive challenges, such as impaired concentration, orientation, and memory recall. The persistent exposure to a deluge of information and stimuli can overwhelm the brain, resulting in forgetfulness and diminished ability to focus. Furthermore, it can heighten the risk of cognitive, emotional, and behavioral disorders, potentially leading to early onset dementia. For more insights on how screens and digital devices impact memory, you can explore the detailed discussion available on Neurocenter NJ, which highlights the detrimental effects of excessive screen time on mental health.
Increased risk of internalizing problems such as depression, anxiety, and social anxiety.
Excessive technology use, particularly social media, can lead to increased risks of internalizing problems such as depression, anxiety, and social anxiety, as it fosters comparison and reduces enjoyment of the present moment. This behavior also disrupts sleep and exacerbates anxiety through constant exposure to negative news and self-diagnosis. Similarly, extensive screen time is associated with higher levels of depression, anxiety, social anxiety, aggression, and defiance. It alters brain development and leads to lasting mental health issues, including increased stress and behavioral dysregulation.
