New Delhi: Prolonged mindless scrolling on social media can physically shrink the brain, impairing memory, focus, and decision-making abilities, according to health experts citing recent studies. According to reports, Mumbai-based orthopaedic surgeon and wellness advocate Dr. Manan Vora highlighted these risks in a viral Instagram video, warning that over two hours of daily “brain rot” activity reduces grey matter in key cognitive regions, akin to the brain “slowly switching off.”
Dr. Vora explained that constant low-effort digital stimulation dampens meaningful neural activity, leading to cognitive underuse. This weakens concentration, information retention, and judgment over time, fostering a foggy mental state often dubbed “brain rot” — Oxford’s 2024 Word of the Year. Research links the habit to dopamine-driven addicti
on, where algorithms deliver endless short bursts of reward, overtaxing the brain’s executive functions and mimicking patterns seen in behavioral addictions.
Studies show excessive screen time correlates with emotional desensitization, cognitive overload, and diminished self-concept, particularly among adolescents and young adults. “Zombie scrolling” and “doom scrolling” exacerbate issues like anxiety, depression, and shortened attention spans, potentially raising long-term risks for cognitive decline or early dementia. Neuroimaging reveals reduced activity in prefrontal cortex areas handling planning and impulse control, with over six hours daily tied to acute symptoms like intrusive thoughts, the reports said.
To counter this, experts recommend swapping scrolling for “real life” pursuits: exercise, outdoor activities, face-to-face socializing, or task completion that yields accomplishment. Dr. Vora stressed, “Your brain craves accomplishment, not stimulation,” urging simple detoxes like cycling or meeting friends to restore clarity without formal interventions. While not a clinical diagnosis, “brain rot” signals broader digital overload concerns, prompting calls for mindful tech habits amid rising mental health burdens.
