How Our Addiction To Screens Is Affecting Our Health
What are some potential negative consequences of excessive screen time for children? What is computer vision syndrome? Let's find out more about How Our Addiction To Screens Is Affecting Our Health.

Problems sleeping
Screen time before bed suppresses melatonin production due to blue light emission, leading to difficulties falling asleep, restless nights, and overall poor sleep quality, which can result in health issues like heart disease, diabetes, and depression. This disruption emits blue light that deceives the body into thinking it's still daytime, reducing melatonin production and causing increased mind activation, delayed bedtime, reduced slow-wave and REM sleep, and fragmented sleep, all of which impact Sleep Quality and Overall Health.
Depression
Screen addiction has a profound connection with depression, as research indicates that extensive daily screen time can escalate the risk of moderate to severe depression, particularly in females, leading to mental health challenges such as anxiety and sleep disturbances. According to a study on Screen Addiction, spending more than four hours a day in front of screens is detrimental. Similarly, excessive screen time among youth is linked to increased internalizing problems, including depression and anxiety, which are affected by specific changes in brain development, underscoring the importance of regulating screen time to mitigate these mental health issues. Furthermore, social media, an aspect of screen addiction, can trigger depression by stimulating the brain's reward center, inducing feelings of exclusion and anxiety through comparative analysis of users' online profiles, and disrupting essential sleep patterns associated with depression and other mental health concerns.
Eye strain
Excessive screen time can lead to significant eye strain in children, causing issues such as eye fatigue, dry and irritated eyes due to reduced blinking, and loss of focus flexibility. These conditions elevate potential long-term risks such as myopia, or nearsightedness. Similarly, prolonged screen use can result in digital eye strain and computer vision syndrome. These conditions are characterized by symptoms like eye discomfort, dry eyes, headaches, blurred vision, and neck and shoulder pain, which highlight the importance of regular breaks to mitigate these effects. For comprehensive insights on how to manage this, it's vital to learn about the potential impacts of [screen time on kids' eyes](https://www.chop.edu/news/health-tip/how-too-much-screen-time-affects-kids-eyes) from trusted resources.
Wrist pain
Excessive screen time, particularly from using small electronic devices like phones and tablets, is associated with an increased risk of wrist and hand pain, tendonitis, joint pain, and carpal tunnel syndrome due to prolonged and repetitive use in unnatural positions. Digital device overuse can also lead to similar issues, resulting from the inflammation and strain on tendons and muscles in the hand, wrist, and arm. This highlights the need for modified behavior and potential treatments. For more in-depth insights and solutions, consider exploring the potential for therapies or surgical options as mentioned on Montefiore Nyack Health Blog in severe cases.
Weight gain
Excessive screen time is linked to a higher risk of weight gain and obesity in children, with studies indicating that teens who spend extensive time watching TV are significantly more likely to become overweight. The influence of digital device usage extends to poor sleep quality, which can further lead to increased consumption of calorie-dense foods and nighttime eating. According to the Obesity Medicine Association, these behaviors and environmental factors, such as exposure to junk food ads and overeating during screen time, coupled with reduced physical activity, cumulatively escalate the prevalence of obesity in children. Addressing screen time responsibly can thus play a crucial role in managing and preventing childhood obesity.

Altered brain functioning
Excessive screen time in adults can significantly impact brain functioning, leading to the thinning of the cerebral cortex, reduced gray matter volume, and potential increases in the risk of early neurodegeneration. These changes can also affect learning, memory, and mental health. In preschool-aged children, increased screen-based media use is linked to lower microstructural integrity of brain white matter tracts, which are crucial for language and literacy skills, often resulting in lower cognitive assessment scores. Additionally, screen addiction can alter brain functioning by desensitizing the brain's reward system, affecting dopamine sensitivity. This can have significant implications for focus, motivation, and overall mental health, contributing to issues such as depression, anxiety, and stress.
Increased blood pressure
Excessive screen time is closely linked to a range of health concerns, particularly in relation to cardiovascular health. It is associated with increased blood pressure and several other risk factors for heart-related diseases, including obesity and low HDL cholesterol levels. Additionally, prolonged exposure to screens can disrupt stress regulation, potentially exacerbating these health issues. For more in-depth information on the scientific research concerning the health effects of screens, you can refer to the Environmental Health Trust's detailed overview on how screens and smartphones impact children's health. The risks also encompass insulin resistance, further contributing to the growing concern among health professionals about the pervasive effects of technology on our physical well-being.
Behavioral problems
Excessive screen time is linked to various behavioral problems, including increased stress and anxiety, behavioral dysregulation, and decreased social abilities, as well as higher levels of depression, anxiety, social anxiety, aggression, defiance, and bullying. Additionally, too much screen time is associated with impulsive actions, violence, and a loss of social skills, along with symptoms like irritability, anxiety, or anger when screen time is limited.

Impaired social skills
Excessive screen time impairs social skills in children by reducing face-to-face interactions, leading to decreased social abilities, and hindering the development of effective verbal and non-verbal communication skills. According to AdventHealth Shawnee Mission, too much screen time results in impaired social skills due to fewer real-life interactions, causing social anxiety, loneliness, and less practice in socializing, even though devices are used for socializing. To address these concerns, parents can explore strategies to manage their child's screen addiction, as discussed in Mobicip's Comprehensive Guide for Parents, which offers practical tips and insights for reducing screen dependence and encouraging healthier social habits.
Poor sleep or insomnia
Screen time before bed has been shown to significantly disrupt sleep quality and contribute to conditions such as insomnia. The blue light emitted by devices suppresses melatonin, a crucial hormone for sleep, thereby stimulating the brain and delaying sleep onset. This disruption not only affects the natural sleep-wake cycle but also leads to fragmented sleep and increased sleep latency. According to the Sutter Health website, engaging with screens during nighttime impacts the circadian rhythm, causing difficulties in achieving a restful night's sleep. Such issues are exacerbated by the stimulating content often encountered online, which keeps the mind active and prevents the attainment of slow-wave and REM sleep vital for restorative rest. Overall, reducing screen exposure before bed is essential for maintaining healthy sleep patterns and ensuring adequate rest.
