The therapeutic benefits of yelling

Abstract

Yelling has been used as a form of healing in Indigenous cultures (Nabigon, 2010). Research suggests benefits to therapies that incorporate yelling (Karle, Corriere, & Hart, 1973). However, the physiological impact of yelling has not been investigated. The current study explores EEG measurements of yelling as compared to its derivatives (deep breathing and a vocal control). Ten participants from Laurentian University were recruited. Results of relative spectral power analysis provide evidence of a significant increase in relative gamma power following the yelling condition only (F(14,98) = 2.87, p=.001, ŋ2=.291). POMS scores confirm that there was a significant total mood disturbance reduction following the yelling condition only (t(9)=3.68, p=.005). Findings support strategies designed to enhance health and well-being.
