Laugh to Light up Your Brain

An elegant, mature woman laughs heartily at a joyful joke.

Why does laughter make your brain feel better?

Any comic will tell you, a novel punchline is key to getting a laugh. Surprise and curiosity activate your prefrontal cortex, enhancing neural connections and flexible thinking associated with cognitive resilience.


The excitement of connecting with a joke sets off a process of rigorous brain connectivity. The reward center of the brain releases feel-good hormones like endorphins, dopamine and serotonin, a powerful mood-regulating neurotransmitter. Sharing laughter with others also enhances feelings of well-being and strengthens social bonds.


  • Listen in the moment – discover, create and share humor with those around you.
  • Cut loose and be present in the moment when you share a funny story.
  • Collect an array of inoffensive jokes to help diffuse life's awkward moments.
  • Connect through empathy – seek out shared experiences and kindness.
