The University of Bristol study shows happiness can be learned, but lasting wellbeing requires ongoing practice. The "Science of Happiness" course improved student wellbeing significantly, with 10 to 15% gains.

Long-term benefits of the course were only observed in those who continued applying the taught habits. The study, published in "Higher Education," is unique for tracking student wellbeing post-course over an extended period.

The course content, now summarized in a new book by Professor Bruce Hood, emphasizes positive psychology interventions focused on outward engagement rather than self-focused "selfcare."
