I recently pushed myself to an extreme: 48 hours of near-constant screen exposure, from 10 a.m. Monday to 10 a.m. Wednesday. Screens were on while working, eating, sleeping—even in the bathroom. Brief exceptions included a quick shower and a three-minute shop run for supplies. The outcome? Eye-opening and exhausting.
As a tech writer with years covering digital wellness at MakeUseOf, I've tested wild ideas before—like creating a fake online boyfriend (he turned out to be a jerk) or acting obnoxious with a selfie stick. This time, I volunteered to quantify excessive screen time's effects, drawing from established research.
Studies link heavy screen use, especially in youth, to cognitive decline, mood shifts, and sleep disruption. Victoria Dunckley, M.D., outlines this in her Psychology Today article. Nighttime blue light is a known culprit—apps like f.lux help mitigate it, but I skipped all precautions, ignoring my usual pre-bed screen curfew.
Briallyn Smith, a MakeUseOf author with a psychology degree, designed pre- and post-experiment assessments: an emotional mood survey plus eight Cambridge Brain Sciences cognitive tasks. "These aren't games," Briallyn noted. "The Stroop test feels like digital torture." The hour-long battery was grueling—twice over.
Post-tests, cabin fever hit fast. I'm outgoing, typically gym-bound, lunching out, or meeting friends amid writing gigs. Boredom mounted as I binged TV, cleared my Instapaper queue (still the top iPad reading app), and—even—read a Daily Mail piece. After 17 screen hours, I crashed, resisting alcohol's lure.
Screens glowed relentlessly: desk monitor illuminating the room, iPad blasting YouTube by my face—with sound on. Sleep was fragmented; I tossed, woke repeatedly, and rose unrested. Miserable.
Sleep-deprived, I unraveled. Day one's boredom was manageable; Day two brought lethargy. No work—just movies, TV, excessive tweeting, and failed PlayStation distractions. iPad reading felt worse than paperbacks. I felt flu-like, unmoored.
Exhausted yet screen-bathed again, sleep improved slightly from sheer fatigue—but still poor. Morning Facebook scrolling delayed the final tests.
Concentration tanked. My wandering mind struggled far more than baseline. Subjective misery matched results—Briallyn confirmed notable declines in cognitive performance and mood.
Screens directly and indirectly (via sleep loss) impaired me. Isolating factors is tricky, but the verdict's clear: constant screen time erodes well-being. Post-experiment, a walk outside was pure bliss. Balance screens with real-world novelty and interaction—life's richer offline.
