About this movement

The WHO Guidelines on Physical Activity, Sedentary Behaviour and Sleep for Children Under 5 provide evidence-based limits on screen exposure for the youngest children. They recommend zero sedentary screen time for infants under 1, no more than 1 hour for ages 2–4, and emphasize active play and quality sleep. Families using Phosra can enforce these international health standards as hard device limits during a child's earliest years.
