Families and workplaces are being urged to switch off all smart devices from 5pm this evening and take a 24-hour break from the online world.
CyberBreak is an annual event that encourages people to reset digital routines and create healthier online habits together.
The initiative is being led by online safety charity CyberSafeKids.
Its research shows that large numbers of children have access to internet-connected devices in their bedrooms, with many allowed to have them overnight.
According to CyberSafeKids, boys are significantly more likely than girls to both use devices in their bedrooms and to keep them there overnight.
"When screens follow kids into their bedrooms, it impacts not only their sleep but their overall wellbeing," said Alex Cooney, CEO of CyberSafeKids.
"Children need clear boundaries around screen time and device use at home, starting with switching off at night," she said.
"That's why initiatives like CyberBreak are so important. Taking even 24 hours to disconnect helps families reflect on how and when we use our devices and start building healthier online habits together," she added.
Dr Richard Hogan, author and family psychotherapist, said it is more important than ever for children to have moments throughout their busy day that are free from technology.
"As parents, we must lead by example -– this means engaging with our kids before our phones in the morning - sending the vital message to them that they come first, not our smart devices," Dr Hogan said.
Derek Chambers, Policy Lead, National Mental Health, HSE said the distraction and harm caused by constant social media use is undoubted.
"Taking a CyberBreak gives us an opportunity to take a step back and address how we can find a healthy balance between our online and offline lives, whatever your age," Mr Chambers said.
