Heavy social media use contributes to a stark decline in well-being among young people, with the effects particularly worrying in teenage girls in English-speaking countries and Western Europe, according to the World Happiness Report 2026 published Thursday. 

The annual report, published by the Wellbeing Research Centre at the University of Oxford, also found that Finland is the happiest land in the world for the ninth year in a row. Other Nordic countries such as Iceland, Denmark, Sweden and Norway ranked among the top 10 countries. While India has improved its ranking from previous years, it is still place outside the top 100 at 116.
