In today’s hyperconnected world, screens are nearly unavoidable. Children use them for school and entertainment; adults rely on them for work, communication, and relaxation. While digital technology brings many benefits, excessive screen time and constant sensory stimulation are having a profound effect on our mental health.
From rising anxiety in teens to burnout in adults, the consequences of digital overload are becoming harder to ignore. This article explores how screen time and overstimulation impact mental health, especially in children and adolescents, and what you can do to restore balance.
1. Understanding Screen Time and Overstimulation
Screen time refers to the amount of time spent using devices such as smartphones, tablets, computers, and televisions.
Overstimulation occurs when the brain is exposed to excessive sensory input flashing lights, rapid content, multitasking apps that leads to fatigue, irritability, and trouble focusing.
Common Sources of Overstimulation
-
Fast-paced videos and games
-
Continuous notifications and pop-ups
-
Multiscreen use (e.g., watching TV while scrolling a phone)
-
Loud, colorful, and high-contrast visual content
2. Effects on Children and Adolescents
The developing brains of children are especially sensitive to screen exposure and overstimulation.
Mental Health Impacts
-
Increased anxiety and depression
Studies have shown that high screen time correlates with emotional distress, low self-esteem, and depressive symptoms in kids and teens. -
Sleep disruption

Attention problems

Emotional dysregulation
