Dr. Mark Rosenberg, Director of the Division of Aerospace and Performance Neurology at MUSC, will lead the research initiatives.

"This partnership represents a significant step forward in bringing a new layer of credibility to the growing field of cold water therapy and the well-established benefits of sauna," said Ryan Duey, Plunge Co-Founder and CEO. "In working with MUSC's distinguished medical researchers, we're committed to generating evidence-based data that will help people better understand the benefits of both cold immersion and sauna for a range of different scenarios. We hear first hand about them daily from our customers and we’re excited to have a partner in MUSC to help deepen our understanding of the benefits of these modalities."
