LIGHT RAIN WITH SOOTHING DREAM PAD FOR FINDING INNER PEACE.
WHY TO LISTEN : When listening to natural sounds, the brain connectivity reflected an outward-directed focus of attention; when listening to artificial sounds, the brain connectivity reflected an inward-directed focus of attention, similar to states observed in anxiety, post-traumatic stress disorder and depression. There was also an increase in rest-digest nervous system activity (associated with relaxation of the body) when listening to natural compared with artificial sounds, and better performance in an external attentional monitoring task.
Interestingly, the amount of change in nervous system activity was dependent on the participants’ baseline state: Individuals who showed evidence of the greatest stress before starting the experiment showed the greatest bodily relaxation when listening to natural sounds, while those who were already relaxed in the brain scanner environment showed a slight increase in stress when listening to natural compared with artificial sounds.
The study of environmental exposure effects is of growing interest in physical and mental health settings, and greatly influences issues of public health and town planning. This research is first to present an integrated behavioral, physiological and brain exploration of this topic.
