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.

All data collection will occur remotely using REDCap (via University of North Carolina, Chapel Hill) and SinuSonic use will take place in participants' homes. As this is a single-arm, feasibility/pilot study, all participants will follow the same protocol. 1. Baseline Research Session: self-report completion of demographic information, health information \[Short Form Health Survey (SF-20), Total Nasal Symptom Score (TNSS)\], autonomic reactivity (Body Perception Questionnaire, BPQ), anxiety/depression (Hospital Anxiety and Depression Scale, HADS), and adverse experiences (Adverse Traumatic Experiences Scale, ATES). 2. Begin use of SinuSonic twice per day, every day, for 5 weeks. Duration of each use is approximately 2 minutes. During these 5 weeks, participants will be asked to complete weekly forms to document SinuSonic usage and current nasal symptoms \[Patient Global Impression of Change (PGIC), Total Nasal Symptom Score (TNSS). 3. Post-intervention Research Session: after 5 weeks of SinuSonic use, self-report completion of symptoms (PGIC, TNSS), autonomic reactivity (BPQ) and anxiety/depression (HADS).
