Effects of SinuSonic on Psychological and Physical Well-Being

The goal of this clinical trial is to evaluate the effects of using the SinuSonic on psychological and physical well-being in adults who have nasal/sinus congestion. The study aims are: * Aim #1: to evaluate the effect of the SinuSonic on physical and psychological well-being in individuals with chronic nasal congestion; * Aim #2: to evaluate the relationship between autonomic reactivity and psychological well-being (i.e., anxiety and depression) in individuals with chronic nasal congestion; * Exploratory Aim: to evaluate the impact of adverse experiences on physical and psychological well-being in individuals who experience chronic nasal congestion. Participants will be asked to complete self-report measures of physical health, mental health and autonomic regulation before using SinuSonic (i.e., baseline research session) and after 5 weeks of directed use (post-intervention). Demographic information and adverse experiences will be documented during the baseline research session. Participants will be asked to document (weekly) current nasal symptoms and SinuSonic usage.
