According to neurologists, the brain was never designed to remain continuously engaged for hours every day without pause. Earlier, ordinary moments naturally allowed the brain to slow down. But now, every gap is occupied by digital input.
“In a hyper-connected age, no one is truly 'off' anymore. With smartphones and social media, incessant notifications, streaming platforms and the pressure to be engaged all the time, the human brain is exposed to constant background stimulation like it has never been exposed to before,” said Dr Prabhu, Neurologist, HOSMAT Hospitals.
The problem, experts explain, is that stimulation does not always feel exhausting in the moment. In fact, scrolling or binge-watching often feels relaxing. But neurologically, the brain may still be processing information continuously.
“Technology has allowed us to live faster, more connected lives, but it has also quietly changed the way we rest. A lot of people can seem to be physically inactive but their mind is always rolling, scrolling, replying, consuming and processing,” Dr Prabhu added.
This constant intake of information keeps the nervous system mildly alert, even during supposed leisure hours. Over time, that low-grade mental engagement can build into cognitive fatigue.
A 2023 advisory from the Centers for Disease Control and Prevention (CDC) also highlights how insufficient mental and physical rest can affect memory, mood, focus and long-term brain health.
