“The Neuroscience Behind Your Social Media Addiction: The Role of Dopamine in Endless Scrolling”

“

Scrolling through endless social media feeds or indulging in online shopping triggers the same dopamine hits in our brains as scratching an itch. This neurotransmitter, responsible for feelings of satisfaction, reward, and accomplishment, keeps us coming back for more, just like an addiction.

At London Southbank University, my team and I have delved into how increased social media use can lead to lasting brain changes, specifically in teenagers and young adults. This phenomenon, known as “dopa-mining,” can alter brain regions and connections, similar to the impact of drugs, alcohol, or gambling.

Every notification, “like,” or viral video we engage with activates the brain’s reward system, the nucleus accumbens, which generates pleasure akin to winning money or eating your favorite treat. However, repeated exposure to social media can train our brains to seek these dopamine hits compulsively, leading to changes in brain structure and function.

Have you ever found yourself glued to your screen, promising just “five more minutes” of scrolling, only to lose track of time? This addictive nature of social media is designed to keep us hooked, triggering dopamine release and making it challenging to disengage.

Research shows that heavy social media use can increase feelings of stress, anxiety, and depression, as platforms like Instagram foster a desire for external validation. Conversely, those who limit their social media consumption report feeling more confident and less concerned about others’ opinions.

Understanding how social media impacts the brain’s default mode network, responsible for self-reflection and decision-making, is crucial. By examining brain activity using EEG, we aim to uncover how excessive social media use disrupts this network, potentially impairing attention, emotional regulation, and mental well-being.

While giving up social media entirely may not be necessary, being mindful of its effects on the brain can help regain control over habitual use. Awareness is the first step towards maintaining a healthy balance between online engagement and real-life interactions.
