Relaxing sound river Why Nature Sounds Are Great for Relaxation

Rumble/ Natural sounds and green environments have been linked with relaxation and well-being for hundreds of years. But unique to this study is that it was one of the first to use brain scans, heart-rate monitors, and behavioral experiments to suggest a physiological cause for these effects.

To investigate the connection between the brain, the body, and background noise, the researchers recruited 17 healthy adults to receive functional magnetic resonance imaging fMRI scans while listening to a series of five-minute soundscapes of natural and artificial environments.

Participants also performed a task to measure their attention and reaction time during each soundscape. Their heart rates were monitored as well to indicate changes in their autonomic nervous systems the system of organs involved in involuntary processes such as breathing, blood pressure, temperature, metabolism, and digestion.
