Overview
- A Psychological Bulletin meta‑review pooling 71 studies with nearly 98,000 participants reports consistent links between heavier, hard‑to‑control short‑video use and poorer attention, weaker impulse control, and higher stress.
- An EEG study from Zhejiang University finds heavy short‑video users show reduced frontal theta activity, a neural signal tied to executive and attentional control.
- The associations are stronger for addictive or hard‑to‑control use than for total screen time alone, according to the review.
- Clinicians describe rising cases of fatigue, reduced focus, and relationship strain tied to excessive scrolling, while recommending digital‑hygiene steps such as time limits and sleep protection.
- Design features that deliver rapid novelty and instant rewards may reinforce compulsive viewing, with concern heightened for young users in large markets such as India, reported to have over 500 million short‑video users.
