Why It Works

Your Nervous System Needs More Than Rest

Stress accumulates in the body. Chronic stress keeps your nervous system locked in fight-or-flight, making real recovery impossible no matter how much sleep you get or how many supplements you take.

Contrast therapy, cold exposure, and breathwork give your nervous system a direct input signal. They don't just relax you. They retrain your biology.

"I came in anxious and left feeling like myself again. The contrast therapy reset something in me that I didn't know how to reach on my own."

"As an athlete, this is the best recovery tool I've found. Three rounds of contrast and I feel better than I do after a week of traditional rest."

"I was terrified of the cold plunge. Michael walked me through the breathwork first and I made it 3 minutes on day one. I'm hooked."

About Plunsana

A Studio Built on Personal Practice

Plunsana was founded in St. Petersburg, FL by Michael Thomas, a breathwork instructor and nervous system regulation coach. Former Wim Hof Method Instructor. The studio exists because these tools changed his life and the lives of hundreds of people he's worked with, and most of them had never had easy access to all of them in one intentional space.

Plunsana isn't a spa. It's not a gym. It's a recovery studio with a clear philosophy: give your nervous system a direct signal, and your body will do the rest.

Frequently Asked Questions

No experience needed. All new members receive a complimentary orientation that walks you through the protocol, the space, and the safety guidelines before your first session. We've welcomed complete beginners every day since we opened.
Plunsana is located at 2300 26th St N Suite B in St. Petersburg, FL 33713, in the Tyrone neighborhood. Ample parking directly in front. Just minutes from downtown St. Pete off I-275.
Contrast therapy is the practice of alternating between the sauna (heat) and cold plunge (cold) in repeated cycles. The rapid temperature change drives vasodilation and vasoconstriction in sequence, training your vascular system and triggering a powerful neurochemical response. Most sessions involve 3 to 5 rounds of sauna and cold alternation.
No membership required. You can book a drop-in session anytime for $40. Memberships are available for anyone who wants to come regularly and save per visit. See our Memberships page for pricing and options.
Bring a swimsuit and sandals. We provide towels for every visit. Water is available in the studio. If you forget anything, we have you covered.
