When people spent a few minutes each day paying attention to something good in the Big Joy Project, many reported feeling better after a week.
The activities were simple enough to fit into an ordinary day. Participants were prompted to make a gratitude list, celebrate someone else’s good news, plan a kind act, or watch a short video meant to inspire awe. Each activity took about five to ten minutes.
After a 2025 study analyzed 17,598 participants from 169 countries and territories, here’s what it found: At the end of the seven-day program, participants reported better emotional well-being, more positive emotions, and less stress than they had at the start. They also rated their sleep and physical health slightly better. People who completed more activities tended to report larger changes.
Participants volunteered, and the study had no randomized comparison group. It cannot establish how much of the change came from the activities, whether any one activity worked better than another, or whether the reported gains lasted. Sleep and health were self-rated; researchers did not measure them independently.
People who completed more activities tended to report larger changes.
Study collaborator Elissa Epel concluded that “Micro-acts of joy focus us on what is good about the life in front of us, and how we can make it better.”
