The latest Australian research confirms: reducing screen time isn't about punishment. It's about reclaiming the cognitive capacity required for a happy, resilient adolescence.
Data from the eSafety Commissioner (2024) identifies a specific tipping point. For Australian adolescents (10-14), usage under 2 hours has negligible impact.
However, crossing the 2.5-hour threshold triggers a sharp decline in "Emotional Regulation"—the ability to manage stress and recover from setbacks.
Key Finding: Heavy users (5h+) are 3x more likely to report feelings of "overwhelm" than moderate users.
Why is it so hard to put down? Research from the University of Sydney Brain & Mind Centre (2025) explains the mechanism of "High-Effort" vs "Low-Effort" rewards.
Screens provide "Cheap" dopamine (Low effort, high spike, fast crash). Real achievements provide "Rich" dopamine (High effort, sustained satisfaction).
Short-form video (TikTok/Reels) triggers a dopamine spike every 15 seconds. This conditions the brain to reject "slow" activities like reading or homework, which feel painfully boring by comparison.
Like sugar, the brain builds tolerance. A 10-year-old needs more shocking, louder, or faster content to get the same "hit" over time.
It is not just about what screens do to you, but what they take away from you. This is the theory of "Displacement."

Read Paper ↗Strategic frameworks for parents to improve digital quality and reduce quantity, based on evidence from the eSafety Commissioner.
Environment Design: Establish a dedicated charging station in a communal area (kitchen/hallway). Devices must "land" here by 8 PM.
Quality Shift: Don't just police the device; sit next to them. Ask: "Show me the funniest thing you saw today" or "Teach me how this game works."
The Ratio Rule: Implement a 1:1 trade. For every minute of "Green Time" (outdoors, sports, unplugged play), they earn a minute of "Screen Time."
Parental Modelling: Kids engage in "mirroring." If you check emails at dinner, they will check texts. Declare specific zones (e.g., the dinner table, the car) as "Phone-Free" for adults too.
Based on templates from the eSafety Commissioner.

Founder & Dad
When the Australian government first announced the ban on social media for under-16s earlier this year, my immediate reaction wasn't relief. It was discomfort.
I work in the technology industry. For years, I told myself that "educating" my kids was better than banning them. I realise now that was confirmation bias at work. I was looking for reasons to justify the devices I had already given my 10 and 12-year-old, rather than looking at the reality of what was happening to them.
I am embarrassed to admit that despite my industry expertise, I made a mistake. I bought into the idea that restriction was "backward." But seeing the data—and seeing the changes in my own home—I realised I needed to pivot.
We are now winding back usage in our house. It isn't easy, but it is necessary. I built LessIsMore.au not to shame parents who are in the deep end, but to say: It is never too late to change course. If you want to wind back too, you are not alone.
