The science is in. All kids deserve to thrive in mind and body. But in order for them to reach their full mental, emotional and intellectual potential, we have to foster the important connection between the health of the body and of the brain.

Their bodies have to move to get the wheels in their brains turning. Kids need to be active. Their brain health depends on it. It’s time for them to drop the phones, get off the couch and break a sweat – now more than ever.

Brainy BrookFor decades, we’ve known that physical activity improves heart health, helps maintain healthy body weights and builds strong bones and muscles in kids across a range of skills and abilities. But we may have been overlooking what physical activity does for one their most vital and complex organ: the brain.

A growing body of evidence indicates that physical activity in childhood is essential for a healthy brain and leads to improved:

  • thinking and learning
  • emotional regulation and self-control
  • problem-solving ability
  • memory
  • brain plasticity – the growth of new brain tissue
  • stress management
  • ability to cope with anxiety and depressive symptoms
  • self-esteem and self-worth
  • attention and focus

While 62% of 3- to 4-year-olds are reaching their recommended physical activity levels as outlined in the Canadian 24-Hour Movement Guidelines for the Early Years, only 35% of 5- to 17-year-olds are achieving the recommended activity levels for their age group. We also know that 76% of 3- to 4-year-olds and 51% of 5- to 17-year-olds are engaging in more screen-time than is recommended by the Canadian Guidelines for screen-based sedentary behaviours.

Canadian kids are sitting too much and moving too little to reach their full potential.


Moving > Cramming

  • Brainy Brook Student Students who exercise before a test show stronger brain function than those who are less active.26 So, next time students feel the pressure to cram, encourage them to take an active break from studying: some heart-pumping physical activity may actually be the smarter study technique
  • When the body doesn’t move enough, the brain can’t perform to its fullest potential. Children with poor aerobic fitness appear to have more difficulty solving problems27-29 and are more likely to make mistakes when trying to sort out a challenge.30

Busy Bodies = Bigger Brains

  • Sections of the brain dedicated to memory and learning (hippocampus and basal ganglia) are larger in active children in comparison to their less active peers.31
  • Being physically active can boost memory in children and youth,32,33 including those with some brain-based disabilities (e.g., attention deficit hyperactivity disorder, autism spectrum disorder, cerebral palsy).34,35-37

Active Bodies → Innovative Ideas

  • light bulb iconActive kids are better equipped to get creative.30
  • Even if they aren’t artistic, creativity can manifest in think-on-your-feet scenarios such as strategizing for a game, leading a team project or solving a math problem. Without adequate physical activity, it’s difficult for kids to tap into their full potential!

Zooming Around Helps Them Zoom In!

  • Kids who participate in physical activity have more focused and longer attention spans, compared to their less active peers.32,33
  • This correlation appears to be consistent for all children and youth, including those with attention deficit hyperactivity disorder and autism spectrum disorder.38

+ Boosting kids’ physical activity levels could be the missing part of the equation in supporting their mental health.

Breaking a Sweat Releases Happy Hormones Kids Who Move Feel Great!

  • Just like adults who love that “runner’s high” from going the distance, kids who are active experience the same rush of feel-good brain chemicals (serotonin and dopamine).37
  • Children and youth who are fit benefit from this rush of chemicals and experience fewer depression-related symptoms than those who are not fit.35,36
  • Kids with brain-based disabilities are at an increased risk for mental health problems, so they have even more to gain from getting, and staying, active.31

↑ Movement = ↓ Symptoms of Anxiety

  • sport ballsEvidence suggests that physical activity may help lower feelings of anxiety in children and youth,39,40 Dance and team sports may be especially effective in children and youth with brain-based disabilities.41,42
  • Canadian kids are on the right track here, with 77% of 5- to 19-year-oldsand 46% of 3- to 4-year-olds participating in organized physical activities or sport.2014-16 CANPLAY

↑ Movement = ↓ Stress

  • Research suggests that physical activity is an effective tool in alleviating social and academic stress in young people; those kids who are less active have measurably higher levels of the stress hormone cortisol in their bodies.43
  • Moreover, being active not only appears to bolster kids’ resiliency when they are dealing with stress, but it appears to help them recover from stressful situations faster.43
  • Being active outdoors, even for a simple walk, is a powerful antidote for adolescents facing stress.20 But with only 37% of 11- to 15-year-olds in Canada playing outdoors for more than 2 hours per day (outside of school hours)2013-14 HBSC we have a long way to go to ensure they are reaping these mental health benefits.

↑ Movement = ↑ Self-esteem

  • Social media plays a major role in self-esteem for many young people. Kids are subjected to never-ending online scrutiny from their peers. Getting active can be a protective tool to bolster kids’ self-esteem, confidence and self-worth.20
  • Real-world physical activity can distract them from these virtual experiences that could erode how they perceive themselves.45
  • When children and youth get active, research shows that they have improved self-esteem, which in turn leads to better moods and an overall more positive sense of satisfaction with how they perceive themselves.46-51 Yet, 5- to 11-year-olds and 12- to 17-year-olds in Canada spend 2.3 and 4.1 hours per day, respectively, in screen time pursuits,2014-15 CHMS leaving little time for offline, active movement.

We all want to see Canadian kids realize their potential physically, emotionally and cognitively. A healthy brain is one of their greatest resources – today and into the future.

Engaging kids in daily physical activity may be the most accessible, but underutilized, way to support them on this journey. Let’s work to balance the equation.
