Vagal Approaches on Long COVID-19

Impact of Vagal Approaches on Symptomatology in Long COVID Participants

The purpose of this study is to explore whether two general wellness products, alone or combined, can support individuals experiencing Long COVID symptoms. Both wellness products stimulate the vagus nerve - a nerve that helps regulate stress, relaxation, mood, breathing, heart rate, inflammation, and digestion.

The investigators will use a Fitbit to track participants' health measurements including, but not limited to, activity, heart rate, and heart rate variability, and participants will be asked to complete surveys about their experience. This information will be collected into a repository where participants can share their experiences with Long COVID symptoms.
