Researchers at the University of California, San Francisco, have shown that just one week of simple acts of kindness can noticeably improve emotional well-being. The study involved 17,600 people from 169 countries. Over seven days, participants completed simple tasks through the online Big Joy program — sharing moments of joy, thanking others, or performing small acts of kindness.
As a result, most participants reported better sleep, lower stress, and more positive emotions. The effect was especially pronounced among young people, ethnic minorities, and people from socially vulnerable groups, who often do not have access to traditional forms of psychological support.
Even a minimal daily effort — just a couple of minutes — can bring tangible benefits. The effect was stronger in those who completed the tasks more actively. This makes the approach universal and accessible, regardless of income or education level.
The study is especially relevant against the backdrop of rising anxiety, burnout, and stress in society. A simple, accessible, and almost universal program could become a kind of "mental vaccine" — protection for mental health.
