Research suggests laughter and play are fundamental to healthy brain growth, emotional well-being, and social bonding in children. According to Jacqueline Harding, Ph.D., an early childhood expert at Middlesex University in London, joy is a complex biological phenomenon that helps children navigate stress and build more resilient minds. In her book “The Brain That Loves to Laugh,” Harding argues that hope and humor are not just pleasurable but foundational to a recipe for healthy development.
Brain Activity and Molecular Effects
Laughter activates broad brain networks including motor regions and the prefrontal cortex long before children learn to speak. By helping the brain resolve conflicting ideas, laughter boosts creativity and engages working memory, functioning as a “mental workout.” At a molecular level, laughter decreases stress hormones like cortisol and epinephrine while increasing “happiness chemicals” like dopamine, serotonin, and endorphins. Laughter also boosts oxytocin, which deepens emotional bonds between parents and children. In contrast, prolonged stress impairs learning, suppresses immune function, and alters the developing limbic system that governs emotion and long-term memory.
Building Resilience Through Play
Parents can foster these benefits through spontaneous play and joyful connection. These interactions do more than spark laughter—they help children develop emotional regulation, strengthen feelings of safety and connection, and support social and cognitive development. Through repeated positive early experiences, children develop “co-regulation,” learning to manage their own stress by drawing on a biological store of positive experiences. These spontaneous, joyful moments act as an antidote to stress and help young minds become more receptive to learning. Experts advocate for integrating humor directly into classrooms to reduce cognitive load and improve how children retain key concepts. By uplifting the nervous system, joy creates an optimal environment for information absorption. As the American Academy of Pediatrics notes, safe relationships and non-stressful play environments promote learning better than curriculum prioritization alone.
