The World’s Greatest Laugh Why Because laughter lifts our mood, and even intentional laughter can trick the brain into feeling happier in the moment. It is silly, fun, and playful — a simple way to let go and reconnect with joy.
How Children laugh together, beginning with playful silliness until it turns into genuine laughter. As the group gathers, the energy builds and those willing to let go soon find themselves laughing for real. Children, with their natural openness, often burst into true laughter right away.
What Together we are creating the world’s greatest laugh — a mural of faces that, in years to come, will show children from every corner of the world laughing side by side on our webpage. This collective chorus of joy will become a massive global laugh, a shared celebration of playfulness and kindness. Recordings are shared online to inspire others. Children learn a simple exercise to bring joy into their body, and short clips of them laughing for 20–30 seconds are shared through out social media, encouraging a wave of laughter worldwide. Others are invited to join by recording themselves, tagging Happy Hearts, and adding their laughter to our Happiness Manifestation — spreading the word and becoming part of our vision for a more playful and kind world.
Impact This initiative adds the power of a collective laugh that spreads smiles like confetti as a part of our global happiness manifestation
Research/Science (Handbook) Laughter increases oxytocin, dopamine, and endorphins. Shared laughter enhances bonding and reduces stress. When our face is relaxed, only a few muscles are engaged, but smiling activates many more, sending signals to the brain that lift our mood and in turn make us feel happier. Intentional laughter, combined with deep breathing, reduces stress, boosts mood, strengthens the immune system, improves cardiovascular health, increases oxygen supply to the body, and enhances social connection. This simple practice promotes both physical and mental well-being, creating a positive attitude and a sense of lightness and connection among participants. The benefits of laughter are supported by some scientific evidence, but more high-quality, large-scale research is still needed. It is our intention to contribute to this field by researching these effects with children around the world.
