Results

This study examined the physiological and psychological reactions of gambling disorder (GD) patients while listening to forest or city sounds. Twelve Japanese male GD patients were exposed to sound for 1 min via headphones. Oxy-Hb levels of the bilateral prefrontal cortices were lower when patients listened to forest sounds. This is the first study to show that sounds of forest relaxed individuals physiologically and psychologically to minimize GD.
