Research Shows Green Space Benefits Health in Many Ways This research adds to a substantial body of evidence that proximity to nature and time spent outdoors is good for human health and well-being. And an environment that is filled with natural sounds feels safe and allows us to let our guard down,” she says. “From an evolutionary perspective, humans are hardwired to attend to signals of danger and security. The study’s lead author, Rachel Buxton, PhD, a research associate and conservation biologist in the Department of Biology at Carleton University in Ottawa, says she isn’t surprised by the findings. Water sounds, such as that gurgling brook or a steady waterfall, tended to be the most effective at improving positive affect (the psychological term for a more positive outlook or disposition and the experience of joy and interest), while bird sounds were best for lowering stress. Participants reported less stress and improved health outcomes, like decreased pain, after listening to recordings of nature sounds. įor the review, the researchers looked at 18 studies investigating the health benefits of natural sound study participants listened to recordings of outdoor sounds in laboratory settings. The whoosh of wind through a stretch of forest, birds calling to one another as they land on branches, the gurgle of a brook over a rocky bed - these are the kinds of sounds that are not only calming, but could have profound health and well-being benefits, according to a research review in the April 2021 Proceedings of the National Academy of Sciences.
