Using Play to Rewire & Improve Your Brain | Huberman Lab Essentials
Huberman explains how play functions as a powerful neurobiological tool for brain development and mental flexibility throughout the lifespan. He argues that play isn't just a childhood activity but a critical mechanism for engaging neuroplasticity, expanding cognitive flexibility, and improving performance in work and relationships by safely testing different behaviors and outcomes. The episode synthesizes neuroscience research on the brain chemistry of play with practical guidance on how adults can adopt a more playful mindset to rewire their brains.
Key takeaways
- • Play engages the periaqueductal gray, a brainstem region that releases endogenous opioids, which allows the prefrontal cortex to explore more behavioral possibilities and increases cognitive flexibility.
- • The optimal state for play requires low adrenaline and elevated endogenous opioids—meaning activities must feel low-stakes and exploratory rather than highly competitive or outcome-focused to trigger neuroplasticity.
- • Role-playing and games that allow multiple identities (like chess, where each piece has different rules) are particularly effective for expanding the brain's capacity compared to linear activities or video games with fixed avatars.
- • Play postures—like head tilts, soft eyes, and open facial expressions—are hardwired signals that communicate playfulness across both animals and humans and reflect an internal state conducive to learning.
- • Engaging in novel forms of dynamic movement (dance, soccer, sports with multi-directional motion) during play activates the vestibular system and cerebellum, creating conditions for enhanced neuroplasticity compared to linear movement.
- • Personal play identity formed in early adolescence (ages 10–14)—whether you were competitive, cooperative, a leader, or a follower—shapes how you approach challenges, relationships, and hierarchies as an adult.
