Active Body, Active Mind
At the Smart Kids Conference 2025, Dr. Tommy Wood presented a compelling case for the importance of movement, play, and recovery in brain development. As a paediatric neuroscientist, he explained how the brain, like muscles, adapts and grows through challenge, stimulation, and proper rest.
The Brain Needs Stimulation to Grow
The brain takes around 30 years to fully develop, and throughout this time, its function and structure are shaped by experience. Stimuli such as physical activity, learning new skills, and social interaction are essential drivers of this development.
Movement Builds Cognitive Strength
Just like exercise builds muscle, physical activity supports brain function. Activities such as sports, unstructured play, and even video games (in moderation) help develop executive function, memory, and emotional resilience. Exercise is especially helpful for children with neurodevelopmental disorders like ADHD or ASD.
Learning and Creativity as Brain Training
Learning languages and playing music both enhance cognitive flexibility and working memory. These complex activities offer benefits across age groups but are especially powerful when started young, particularly for children from disadvantaged backgrounds.
The Power of Play and Taking Risks
Outdoor play and mild risk-taking (like climbing or exploring) help children build confidence, reduce anxiety, and develop problem-solving skills. Overprotective environments may hinder development and increase risk-seeking behaviour later on.
Video Games: Friend or Foe?
Video games, when balanced with real-world activities, can improve reaction time and decision-making. The key is moderation—excess screen time that replaces sleep, physical activity, or social interaction can be harmful.
Rest and Recovery Matter
The brain consolidates memories and clears waste during sleep. Children need proper rest to grow intellectually and emotionally. Caffeine and screen time can disrupt sleep, especially in the evening, affecting school performance and emotional regulation.
The Social Media Trap
Social media can increase stress, depression, and feelings of isolation—especially in girls. Replacing screen time with real-life connections and active play supports better mental health.
Final Thoughts
Dr. Wood’s message was clear: to help kids thrive, we must prioritise movement, learning, play, and rest. A well-stimulated brain, supported by recovery and meaningful human connection, leads to better focus, academic performance, and emotional well-being.
