Study start date: October 27, 2025

Actual date on which the first participant was enrolled.

This study aims to see if two general wellness products can help people who have lingering symptoms after having COVID-19, often referred to as Long COVID. These products are designed to stimulate the vagus nerve, which plays a role in managing stress, mood, breathing, heart rate, inflammation, and digestion. The study is important because it seeks to find new ways to support those experiencing ongoing symptoms after COVID-19, which can be disruptive to daily life and challenging to manage. Participants in the study will use a Fitbit device to monitor their health, tracking data like physical activity levels and heart rate patterns. They will also fill out surveys to detail their symptoms and experiences throughout the study. All of this information will be collected to create a repository, allowing for a shared understanding of how Long COVID affects individuals and whether the wellness products have a positive impact on their symptoms.
