Nature’s ripple effect: New study finds visits to parks and blue spaces lift daily happiness for the whole day
A new international study shows that spending time in natural spaces—whether green parks or blue rivers and lakes—can boost happiness not just momentarily but for the entire day. The research, drawing on a large sample of adults and focusing on “yesterday’s” mood, found that people who visited green or blue spaces tended to report higher happiness levels on the whole day compared with those who did not. Importantly, this positive spill-over appeared to hold for people with common mental health conditions such as depression and anxiety, suggesting nature visits could be an accessible way to support daily well-being beyond conventional treatment. Yet the study also revealed nuance: while green spaces were consistently associated with happier days, blue spaces did not uniformly lower anxiety for everyone and, in some cases, were linked to higher anxiety among those with mental health disorders. Researchers stress that these patterns are associations rather than proof of causation, and they call for further research to unpack the mechanisms and duration of these effects.
