About the Book

Todos hemos escuchado que los niños no deben pasar demasiado tiempo frente al televisor o la computadora, pero ¿y nosotros los adultos? Muchos de nosotros pasamos horas mirando las pantallas, con muchos trabajos que requieren que nos sentemos frente a la computadora y la mayor parte de nuestro tiempo libre lo pasamos navegando, tratando de navegar por las redes sociales en los teléfonos celulares y buscando historias en tabletas, especialmente ahora que la pandemia ha convertido a Internet en el principal medio por el cual nos comunicamos entre nosotros.
Cuando se trata de adultos, ¿cuánto tiempo pasan frente a las pantallas?
Hace unos años, los adultos estadounidenses pasaban un promedio de 11 horas al día frente a una pantalla. Desde el cierre, esta cifra ha aumentado a 19 horas diarias sin precedentes durante la pandemia. ¿Quiere ver cómo se compara su tiempo de pantalla con el estadounidense promedio? Hasta cierto punto, es posible que pueda estimar cuánto tiempo pasa en una pantalla cada semana si tiene su teléfono, computadora o tableta configurados para informarle su tiempo de pantalla todos los domingos. El veinte por ciento de todos los adultos encuestados informa estar en línea "casi siempre".
¿Cuándo un adulto se convierte en un tirano sedentario?
Existen límites de uso de pantalla para niños, pero ¿qué pasa con los adultos? No existe una cantidad determinada de tiempo que sea seguro o saludable para que los adultos pasen frente a las pantallas, pero existe una creciente evidencia de que demasiado tiempo puede tener efectos negativos en su salud. Por ejemplo, un estudio encontró que las personas que pasaban seis horas o más al día frente a las pantallas tenían más probabilidades de estar tristes, mientras que otro encontró que limitar el uso de las redes sociales a 30 minutos al día resultó en una "mejora sustancial en el bienestar". ." Tanto la cantidad como la calidad del tiempo de pantalla son importantes.
El insomnio y la mala calidad del sueño son dos de los resultados negativos de pasar demasiado tiempo frente a una pantalla. La luz emitida por las pantallas envía una señal al cerebro para que se mantenga alerta, y la entrada constante durante el día puede dificultar el sueño a la hora de acostarse. Un estudio del sueño en una clínica del sueño puede ayudar si ha tenido problemas para dormir durante mucho tiempo.
Demasiado tiempo frente a la pantalla puede causar fatiga visual y dolores de cabeza. Como resultado de la tensión en sus ojos, ya se ve incrementada por la combinación del resplandor de la pantalla y la intensidad de la pantalla. El estrés puede causar dolores de cabeza a largo plazo.
Prácticas adictivas: los efectos del uso generalizado de las redes sociales y los teléfonos celulares, que han estado disponibles para el público durante poco más de 20 años, aún se están investigando y documentando. Investigaciones recientes han demostrado que algunas personas pueden desarrollar comportamientos adictivos con los teléfonos inteligentes y las redes sociales, como pensamientos obsesivos sobre el dispositivo o la plataforma y el deseo de usarlos, confiando en sus aplicaciones de redes sociales o teléfonos inteligentes para controlar su estado de ánimo o cambiar y experimentar. síntomas de abstinencia cuando no pueden acceder al dispositivo o a las aplicaciones. Si estas acciones eventualmente comienzan a interrumpir la rutina regular de una persona, entonces hay motivo de preocupación.
