The science of the five-minute break.
Movement breaks aren't a reward for good behaviour. They're a biological necessity. Here's the research that shapes every game in ClassBreak.
What happens in the brain.
is how long the average student can sustain focused attention before cognitive fatigue sets in. (Sousa, 2001)
of teachers report that brain breaks visibly improve student engagement and on-task behaviour. (Jensen, 2005)
increase in test scores was observed in schools that introduced structured movement breaks. (Donnelly & Lambourne, 2011)
When students are sedentary for long periods, cerebral blood flow decreases and attention falters. Physical movement — even brief, low-intensity activity — triggers the release of BDNF (brain-derived neurotrophic factor), dopamine, and norepinephrine. These chemicals improve attention, memory consolidation, and mood.
“Physical activity is like Miracle-Gro for the brain.”
What the research says.
Regular aerobic exercise and movement breaks enhance neuroplasticity and significantly improve learning outcomes.
The brain needs movement to consolidate learning. Breaks allow the brain to shift from acquiring information to processing and storing it.
Physical activity is positively associated with academic performance, including grades, standardised test scores, and classroom behaviour.
Students who are more active show greater attention, have faster cognitive processing speed, and perform better on standardised academic tests.
How ClassBreak applies the science.
Every ClassBreak game is designed to fit the 5-minute window research identifies as optimal — long enough to shift brain chemistry, short enough to maintain lesson momentum.
Cognitive load matters. Complicated setup instructions burn the same mental resources you're trying to restore. ClassBreak games have rules you can read in 30 seconds.
Habitual breaks lose their effectiveness. ClassBreak's 1,000+ games ensure novelty — a key driver of dopamine release and attention reset.
