As parents and teachers, you play one of the most powerful roles in a child’s development. Every time you give a child the chance to roll, climb, run, balance or play outside, you are doing far more than helping them burn energy. You are building their brain, shaping their emotional world and strengthening their future learning. Children are made to move. Movement is not a bonus activity. It is part of how they grow.


Yet today’s world makes natural movement harder. Screens are always nearby. Many families have busy schedules. Schools often face pressure to fit more academics into less time. Outdoor spaces are shrinking. When movement becomes limited, children miss essential experiences their bodies and brains desperately need.


This blog gives you practical insight into why movement matters, what happens when activity is missing and how simple daily routines can transform learning, behaviour, sleep and emotional balance.


How Movement Builds Your Child’s Brain


From the moment a baby starts rolling, crawling and pulling up to stand, the brain is wiring itself through action. These movements are not just milestones you tick off. They are powerful building blocks.


Movement strengthens muscles and bones, sharpens balance and coordination and boosts heart health. But some of the biggest benefits happen inside the brain. In Spark: The Revolutionary New Science of Exercise and the Brain, John Ratey describes how French neuroscientist Jean Pierre Changeux found that movement even before birth influences brain structure. When chick embryos were prevented from moving, their brains developed abnormally. This showed how deeply the brain depends on physical activity.


Changeux also discovered the role of a protein called BDNF. This protein helps nerve cells grow strong branches that support learning and memory. Ratey refers to BDNF as Miracle Gro for the brain. Children produce more of this powerful protein when they move. When your child runs, plays tag, hops, climbs or balances, their brain is literally growing.


Movement also improves attention, emotional regulation, sleep and overall mood. It reduces stress chemicals and increases natural feel good hormones. When you encourage your child to move, you are feeding both their body and their mind.





What Happens When Children Do Not Move Enough


As the adult in your child’s world, you may notice when they are not getting enough physical activity. You might see it in their energy levels, their mood or even in their posture.


Physical Development


Inactive children can struggle with posture, stamina and muscle tone. They may avoid active play, tire quickly or fall behind in gross motor skills. Long term inactivity increases the risk of obesity and chronic health conditions.


Cognitive Development


Movement gives the brain the stimulation it needs to stay alert and focused. Research shows that active children generally perform better academically than their sedentary peers. Without enough movement, your child may struggle with concentration, emotional regulation and memory.


Social Development


So much of childhood friendship is built on movement. Games, climbing, chasing, playground adventures and sport help children practice cooperation, empathy and confidence. A child who avoids physical play often misses these social opportunities.


Emotional Development


Movement is a natural stress release. Without it, children may appear irritable, restless, anxious or overwhelmed. Active play helps regulate mood and supports emotional resilience.


Inactivity today often becomes inactivity tomorrow. Early habits matter.

Why Core Strength and Posture Matter More Than You Think


Core muscles, breathing, and emotional regulation


As a parent or teacher, you may notice when a child struggles to sit upright, slouches easily or tires quickly during seated tasks. Core strength is essential for posture, breathing and emotional regulation. Children with weak cores often breathe shallowly, which affects oxygen levels and the ability to self regulate.


Posture also plays a surprisingly important role in speech. The hyoid bone in the neck helps support the tongue, jaw and airway. When a child slouches or pushes their head forward, the hyoid bone shifts. This can impact breathing rhythm, tongue movement and speech clarity.


By encouraging strong posture during writing, sitting on the carpet, walking and active play, you support clearer speech, better breathing and improved classroom readiness.


Movement, BDNF and Learning


Movement increases BDNF, which helps the brain grow stronger connections. The hippocampus, which is responsible for learning and memory, thrives on physical activity. When your child jumps, spins, crawls under a table or balances on a beam, their executive functions are improving. These include focus, working memory and organizational skills. Movement is not a break from learning. It is part of learning.





Screen Time versus Green Time


Excessive screen time is one of the biggest barriers to physical activity. Children who spend more than two hours a day on screens are at higher risk for poor sleep, emotional regulation challenges and weaker attention spans.


Replacing screen time with outdoor “green time” improves focus, mood and physical health. Unstructured play that includes climbing, running, exploring, offers mental and emotional benefits that screens cannot replicate.


Set clear, consistent limits: no screens 2 hours before bedtime, screen-free meals and scheduled outdoor play. The goal is to replace passive time with active, engaging experiences, especially outside.


Why Outdoor Play Is So Important


While indoor play has its place, nothing replaces the benefits of outdoor activity. Nature provides a multisensory environment that stimulates the brain in ways indoor play cannot. Fresh air, uneven terrain, natural sounds and the freedom to explore all contribute to rich developmental experiences for children. Here are a few benefits of outdoor play that we do not always think of.


Sunlight


Exposure to natural sunlight is critical for producing vitamin D, which supports strong bones, immune health and mood regulation. Low vitamin D levels are associated with fatigue and irritability in children, making sunlight an important part of the daily wellness for children. Sunlight exposure further increases the brain's production of serotonin, a chemical that promotes feelings of happiness and well-being.


Furthermore, sunlight plays a crucial role in regulating a child's internal body clock by influencing melatonin production. Exposure to bright light in the morning signals to the brain that it is daytime, which helps to decrease the production of melatonin, the hormone that makes a child feel sleepy. This in turn promotes alertness and can help to align a child's circadian rhythm, making it easier for them to fall asleep later at night.


Sensory Stimulation


Outdoor play naturally engages all senses - the feel of grass, the sound of birds, the sight of open space. These multisensory experiences strengthen sensory integration and help children to filter and process information efficiently. This process is vital for children's learning readiness, emotional balance and social interaction.


Stress Reduction


Spending time in nature has been shown to lower stress hormones and improve emotional well-being (American Psychological Association). Children who spend time outdoors are calmer, more focused and better able to manage frustration.





How Much Exercise Do Children Need?


According to the World Health Organization, children need frequent, varied physical activity each day.


  • Infants (0–1 year): Several periods of interactive, floor-based play daily, including tummy time.

  • Toddlers (1–3 years): At least 3 hours of physical activity spread throughout the day.

  • Preschoolers (3–5 years): At least 3 hours of activity daily, with 60 minutes being energetic play.

  • School-aged children (6+ years): At least 60 minutes of moderate-to-vigorous activity per day, plus strength-building activities three times a week.


When movement is woven into everyday play, these targets are easy to reach.



Practical Ways To Encourage Movement


Encouraging movement doesn’t require expensive equipment. Everyday activities are perfect. You can make movement part of your routine by walking short distances instead of driving, dancing in the kitchen, playing tag before dinner or creating fun indoor movement stations. Children copy what you model. When you join the fun, you build healthy lifelong habits together.


Schools also play a crucial role in supporting children’s movement. Baby rooms should include sturdy mats for tummy time, toys that encourage reaching and crawling, and low furniture like ottomans that will encourage standing and cruising. Preschoolers, on the other hand, will benefit from daily outdoor play, climbing and sandbox exploration.


For older children, structured physical education and unstructured play are equally important as both enhance focus, behaviour and academic outcomes (Harvard Center on the Developing Child). Short classroom movement breaks throughout the day can also improve attention and learning outcomes. Schools that prioritize physical activity often report improved emotional well-being and scholastic performance.


When Professional Help Is Needed


Parents and teachers should be mindful of signs that a child’s physical development or activity levels may need closer attention:


  • Avoiding active play or outdoor time

  • Difficulty with gross motor skills like running or jumping

  • Low muscle tone, poor posture, or quick fatigue

  • Preference for screens over physical play

  • Behavioural signs like restlessness, poor focus, or irritability


If these are present, consultation with a professional such as your school's contracted Kinderkineticist, is recommended.


Sometimes, children avoid movement due to poor coordination, low confidence or underlying medical or sensory challenges. If so, the following medical professionals can be considered to assess a child's development and help create an intervention plan:


  • Paediatricians rule out medical concerns.

  • Occupational therapists address coordination and sensory integration.

  • Physiotherapists or Kinderkineticists build strength, posture and gross motor skills.

  • Psychologists help when emotional or behavioural factors limit participation.


Early intervention promotes confidence, success and enjoyment of movement. It is important that you know that you are never alone. Support is available. If you or your child require help, please feel free to book an online consultation with us. We will be happy to help where we can.

Conclusion


Exercise, outdoor play, sunlight and fresh air are not optional extras in childhood. They are essential building blocks of healthy development. When we consider how BDNF enhances brain growth, how strong core muscles and posture support breathing and speech, and how these skills form the basis of emotional control and academic success, one truth becomes clear: movement is the foundation for learning and lifelong health.


The formula is simple. More play. More sunshine. More fresh air. When you prioritize these for your child or the children in your class, you are helping them not only grow but flourish.


And if your school already uses the EduMove curriculum, you have an incredible advantage. EduMove gives children the movement experiences they need to move smarter and become smarter. It is a powerful gift to their development and an absolute bonus for every child in your school community.
