Hasta ~1 hora/día de contenido educativo y co-visualizado; calidad y contexto importan tanto como la cantidad; no usar antes de dormir.

Contexto

La AAP y la OMS recomiendan limitar pantallas a ~1 hora/día de contenido educativo de calidad para 2-5 años, idealmente co-visualizado con el adulto. La evidencia muestra asociaciones pequeñas pero consistentes entre mayor uso y peor lenguaje, sueño y atención. Las pantallas en el dormitorio y de noche desplazan sueño.

Lo que dice la evidencia

  1. [claim-screen-language-young]screen-timeEvidencia alta

    Greater screen time and earlier screen exposure are associated with poorer early language development; effects are smaller and can be positive when content is educational and co-viewed.

    Mayor cantidad de pantallas se asocia con peor lenguaje; contenido educativo co-visualizado puede ser neutro o positivo.

    Matices: Most evidence is observational; reverse causation possible. Background TV displaces parent-child talk.

  2. [claim-screens-displace-sleep]sleepEvidencia alta

    Bedroom screens and evening screen use are consistently associated with shorter sleep duration and later bedtimes in school-age children.

    Pantallas en dormitorio y uso vespertino acortan y empeoran el sueño.

    Matices: Most evidence is correlational; experimental data are smaller-scale.

  3. [claim-screen-time-small-effects]screen-timeEvidencia mixta

    On average, total digital-screen use shows very small associations with adolescent and child well-being; effects are too small to support strong causal claims at the population level.

    Los efectos promedio son pequeños; el contexto y el contenido son críticos.

    Matices: Specific content (e.g., problematic social media, violent content) and bedtime use may have larger, more consistent effects.
