Three Ways Play Supports Healthy Nervous System Regulation in Kids

When we think about helping children manage big emotions and stressful moments, our minds often jump to strategies like deep breathing, narrating emotions, or calm-down techniques. While those tools can be helpful in the right time and place, one of the most consistently powerful and natural ways for children to regulate their nervous systems is much simpler: play.

Play isn’t just fun and entertainment for kids! It’s one of the primary ways their brains and bodies learn to manage stress, build resilience, find calm, and understand the world around them.

Here are three fundamental ways play supports the development of a well-regulated nervous system:

1. Play Reduces Stress Through Movement

Many adults use exercise to manage stress. Going for a run, lifting weights, or taking a brisk walk can help the brain release chemicals that improve mood and reduce anxiety. For children, play serves a similar purpose.

When kids run, climb, jump, swing, wrestle, or build, they are engaging their large muscle groups and increasing their heart rate. This kind of physical play stimulates the production of brain chemicals like endorphins, which help improve mood and regulate the nervous system.

Movement also provides important sensory input, especially proprioceptive input (input from muscles and joints). Activities like pushing, pulling, carrying, climbing, or rough-and-tumble play help the brain better understand where the body is in space. This type of input helps the nervous system organize, and can help children move from a dysregulated state (overwhelmed, restless, or irritable) toward a calmer, more balanced state.

2. Play Builds Social Regulation

Self-regulation does not develop in isolation; much of children’s emotional regulation develops through modeling and in relationships with others. And, play is one of the most natural environments for this learning. 

When children play with peers or siblings, they are constantly practicing important social skills:

• Taking turns
• Negotiating rules
• Expressing preferences
• Reading facial expressions and body language
• Navigating misunderstandings
• Adjusting behavior 

In these experiences, children begin to understand both their role and others’ roles in social interactions. They start to notice what feels comfortable and safe in relationships and what does not. Over time, they will naturally gravitate toward peers and environments where they feel understood and supported.

These experiences teach children relational regulation: the ability to calm and organize ourselves through connection with others. This skill is important in childhood, and remains important throughout life; many adults still rely on trusted relationships to help them manage stress, regulate emotions, and gain perspective. Play provides children with thousands of small opportunities to practice these relational skills in a low-stakes way.

3. Play Strengthens the Brain’s Imagination and Flexibility

Another critical aspect of play is imagination. When children engage in pretend play they are exercising their brain’s ability to shift perspectives and move their attention. This ability is critical for nervous system regulation.

When people experience stress, the brain can become fixated on the stressor. As adults, this may feel like when we replay worries in their minds or feel stuck thinking about the same problem over and over again. The brain has difficulty shifting its attention to something else. 

Imaginative play helps children practice a different skill: mental flexibility. By pretending they are somewhere else or someone else, children learn that their minds can move between different states and experiences, rather than staying fixed in one place that isn’t serving them.

This doesn’t mean ignoring real challenges. Rather, imagination gives children the ability to step away temporarily, reset their nervous systems, and return to a problem with more capacity. And our children do this instinctually, to support their growing nervous systems. Over time, this flexibility supports creativity, problem-solving, and emotional resilience.

Play Is Essential, Not Extra

In our busy schedules, play is sometimes viewed as a reward that comes after “more important” tasks like schoolwork or structured activities. But from a brain and nervous system perspective, play is not optional! It is essential. When we protect time for unstructured, child-led play, we are supporting the development of the brain systems that will help them manage stress, connect with others, and navigate the world with confidence.
