Research by early childhood expert Dr. Jacqueline Harding outlines laughter's role in brain development and stress reduction. It engages multiple brain regions, precedes speech, and influences hormone levels and immune function. These effects support cognitive growth and emotional regulation in children.
Facts First
- Laughter engages a distributed network of brain regions including motor areas and the prefrontal cortex.
- Laughter precedes the neural development of speech in a child's brain.
- Laughter decreases stress hormones cortisol and epinephrine while increasing dopamine, serotonin, and endorphins.
- Laughter influences heart rate, respiration, and antibody production, affecting physiological health.
- Neuroimaging studies suggest laughter plays a role in brain activity because humor is cognitively demanding and engages neuro-plasticity.
What Happened
Dr. Jacqueline Harding authored a book titled 'The Brain That Loves to Laugh', which references research indicating laughter engages a distributed network of brain regions. Laughter precedes the neural development of speech and influences heart rate, respiration, and the production of antibodies. Additionally, laughter decreases stress hormones like cortisol and epinephrine, while increasing the production of dopamine, serotonin, and endorphins.
Why this Matters to You
If you are a parent or caregiver, understanding laughter's role may help support a child's development. Laughter can boost oxytocin and enhance neural synchrony during parent-child interactions to foster bonding. In a child's brain, the limbic system develops alongside executive functions. Co-regulation could be supported by positive, laughter-filled interactions. Because prolonged stress can impair learning and suppress immune function, laughter's stress-reducing effects might offer a counterbalance.
What's Next
The research suggests laughter is a cognitively demanding activity that engages neuro-plasticity and activates working memory. Further application might involve integrating laughter-inducing activities into early childhood education and parenting practices to support healthy neural and emotional development.
