Why do we do this to ourselves?

Winter can be a lot — grey skies, short days, low motivation — so we’re turning cold water into something that feels good, together.

We started cold dipping during Covid and felt the shift: less Sunday scaries, calmer minds, fewer colds — and that joyful high (and proud grin) when you climb back out. Studies suggest cold dips can support mood and stress; we’ve felt it first-hand.

With Martina Lenk, a certified cold-water coach, we’re making it a community thing. We start in October so your body can ease into cooler lake temps, then meet once a month through winter — for ourselves and for each other (with tea and KULA brownies after).

What to expect

  • Guided, beginner-friendly swim with coach Martina Lenk in Lake Zurich
  • Breathing + safety briefing, then a short dip
  • Warming up together with hot tea and a KULA brownie
  • Friendly faces, a little pride in what you’ve done — and that electric buzz after the cold
