Relationship between social media use, life satisfaction and cosmopolitanism

What is it about?

Many people use social media every day, and researchers want to understand whether this affects how happy and satisfied people feel with their lives. This study followed 986 adults in Japan over six years, from 2019 to 2024, tracking their social media use, sense of global citizenship (cosmopolitanism), and overall life satisfaction. The findings showed that social media use had a small negative effect on life satisfaction over time — meaning people who increased their social media use tended to feel slightly less satisfied with life as the years went on. At any single point in time, however, the connection between social media and life satisfaction was so small it was not practically meaningful. Feeling like a global citizen — caring about people and issues beyond your own country — was strongly linked to higher life satisfaction, both at single points in time and across the full six years, with people who felt more connected to the wider world consistently reporting greater wellbeing. Interestingly, using social media was linked to a slightly higher sense of global citizenship, which in turn was linked to greater life satisfaction, though this positive chain of effects was small and did not hold up over the long term. Overall, the findings suggest that social media's impact on happiness is limited and mostly modest, while feeling like a caring, engaged global citizen appears to be a much stronger path to lasting life satisfaction.

Why is it important?

Billions of people use social media daily, yet most research has only examined its effects on wellbeing at a single point in time. By following the same group of adults over six years, this study provides more reliable evidence about how changes in social media use actually affect life satisfaction over the long run. The findings offer a more nuanced picture — social media is neither simply good nor bad for happiness, but its long-term effects are more consequential than short-term snapshots suggest. Crucially, the study highlights cosmopolitanism — a sense of being a global citizen and caring about people beyond one's own country — as a strong and consistent driver of life satisfaction. This is an important and underexplored finding, particularly in an era of globalisation, digital connectivity, and growing cross-cultural exchange. While social media showed a modest short-term link to cosmopolitanism, this effect did not sustain over time, suggesting that social media alone is insufficient for cultivating the deeper sense of global belonging that cosmopolitanism represents. For individuals, policymakers, educators, and mental health professionals, the key takeaway is clear: fostering cosmopolitanism may be a more powerful and lasting pathway to wellbeing than social media use alone. Programmes and initiatives that build global awareness, empathy, and cross-cultural understanding deserve greater attention — not only as social goods, but as meaningful contributors to individual happiness and quality of life.
