The Brain's Plate
May 16, 2026
Part 4 in the series The Brain, the Screen and the School
In the earlier parts I have written about the tech companies’ design, sleep, and Sweden’s digitalisation strategy.
Now I am turning the question around.
What does the brain need to thrive?
Sissela Nutley uses an image most people recognise: the plate model. Not the one with proteins, carbohydrates and vegetables, but a mental version. Seven segments that together make up the brain’s basic needs.
The Mental Plate Model is not an invention. It is based on research showing that around 40 percent of our wellbeing can be influenced by how we use our time.

The seven segments
The plate consists of:
The deficit
When Nutley shows what this looks like for young people today, it is alarming.

80 percent do not reach the daily recommended level of physical activity.
75 percent sleep less than eight hours per night.
25 percent have less than ten minutes of mind wandering per day.
60 percent would not talk to anyone about difficult thoughts and feelings.
75 percent have no organised leisure activities.
80 percent media-multitask, meaning they do their homework with a screen running.
65 percent have less than four hours of chill time per day.
These are average figures for young people in Sweden. This is how many young people live, day after day. The risks are significant.
When we talk about young people’s mental ill-health, we often talk about symptoms. But perhaps we should talk more about what they lack in their lives.
Chill time has crowded out the rest
There is one segment that has grown at the expense of all the others: chill time. Or more precisely, one specific form of chill time: screen time.
For many young people, the screen has become the only source of recovery. Sleep, exercise and other parts of the plate are absent, or have very little space.
That chill time has increased is not a problem in itself. We need chill time.
The problem is that it has pushed aside so much else we also need.
When one in four secondary school pupils sleeps six hours or less, when 80 percent do not move enough, when 25 percent barely have ten minutes of mind wandering per day — it is also clear that other things suffer.
One segment of the plate becomes so large that the others are crowded out.
What schools can do
Schools cannot fix every segment on their own. But they can do a great deal.
Exercise is built into the school day through PE and breaks, but can be strengthened. Movement in the classroom, movement breaks, longer outdoor recesses, after-school programmes that actually get pupils moving. When the mobile phone ban comes into force on 1 July, Swedish research using accelerometers shows that pupils automatically start moving more. But then schoolyards must also encourage play and sport.
Relationships are built at school every day. Trusted adults who see the pupil. Classmates to eat lunch with. More adults make a big difference. But the greatest difference is made by qualified and licensed teachers.
Focus time is the school’s core mission. And that is precisely why digital distractions are so damaging. Four in ten pupils report being distracted on almost every lesson. That is focus time slipping through our fingers.
Meaningful activities are found in the arts, in music and cultural schools, in community organisations. As a music teacher I have seen what it means. I have written about it here .
Mind wandering is perhaps the hardest. School is intense, lesson after lesson. But a break without a screen is mind wandering. A calm morning assembly can be mind wandering. A quiet classroom can be mind wandering.
The question we rarely ask
In Örebro, as in many other municipalities, we invest resources in student health services, special support, managing absence and disruptive behaviour. That is right and important.
But sometimes it feels as though we are trying to catch water with a sieve.
We need to turn the question around — not “what do we do when they are struggling?” but “what do we give them so they can thrive?”
That is what the mental plate model is about. Not symptoms, but fundamental needs. Not a fix after the breakdown, but structure from the start.
Nutley says that we adults need to shape environments. The point is that we are not just shaping environments against something — we should shape them for something.
For sleep. For movement. For real connections. For time to think.
For a full plate.
In the next part I return to learning itself. How does working memory function? Why is the book actually better than the screen for certain things? And what do we know about AI in the classroom?
