Excessive internet use by children can lead to  behavioural issues, new study finds

'Heavy levels of digital screen time (ie 3+ hours daily) are associated with declines in wellbeing, particularly for external and prosocial functioning, while engagement in learning-oriented digital activities and gaming is associated with better adolescent outcomes.'

Excessive internet use by children impacts their wellbeing, leading to concerns over their conduct and hyperactivity levels — and the effect is greater among those from lower socio-economic backgrounds, according to a new study.

New research based on data from the Growing Up in Ireland (GUI) study found there was a “sharp increase” in engagement with social and media digital activities between the ages of nine and 13, from 41% to 91%, with “full saturation” by ages 17 and 18, when 99% of those in the cohort were actively engaged with online activities.
