The relationship between breath modulations and stress: a 4-week nasal breathing protocol

An individual’s perception of stress can result in negative affect states and increased anxiety, which may further perpetuate the stress cycle. Deep breathing through the nose is a stress management technique that promotes parasympathetic dominance, thereby altering the stress response. The purpose of this study is to examine the short- and long-term effects of a regular deep breathing practice on affect, anxiety, and perceived stress among healthy individuals.

By measuring alterations in affect, anxiety, and perceived stress, we hope to determine if four weeks of deep breathing can alter an individual’s psychological well being. The results of this study will be used to better understand the therapeutic potential of breath control.
