Cold Water, Warm Circle

A Guided Winter Swimming Immersion

Inspired by Susanna Søeberg’s Winter Swimming

This is not a book club.

It’s a practice.

Cold Water, Warm Circle is a small-group, four-session immersion designed to help you experience the science, ritual, and nervous-system benefits of cold exposure — safely, intentionally, and in community.

We’ll use Susanna Søeberg’s groundbreaking research as a foundation, then bring it to life through sauna, cold plunge, conversation, and a culminating open-water lake immersion.

Limited to six participants.

What This Experience Is

  • A guided, facilitated series — not a drop-in

  • Grounded in science, not bravado

  • Designed for people curious about cold exposure but wanting structure, safety, and meaning

  • An opportunity to build consistency and confidence with heat and cold

  • A chance to do something challenging together

You do not need prior cold plunge experience.
You do need curiosity, openness, and respect for your body.

  • This experience is for you if:

    • You’re curious about cold exposure but want guidance

    • You value science and lived experience

    • You’re drawn to ritual, reflection, and community

    • You want to feel calmer, more resilient, and more embodied

    • You enjoy doing meaningful, slightly uncomfortable things with others

    This may not be for you if:

    • You’re looking for extreme cold challenges

    • You want a casual, drop-in book discussion

    • You prefer solitary or unstructured experiences

  • Cold exposure alone can feel intimidating or performative.
    Heat and cold, practiced intentionally and in community, becomes regulating, connective, and empowering.

    This is about learning how to meet stress — and step back from it — with more choice.
