WITH THE BREATH

The art and science
of breathwork

Our breath is our frequency, our energy, our consciousness. With each inhale and exhale, we return to our natural rhythm, rewire old patterns, release what no longer belongs, rewild our spirit, and remember who we truly are.

Every session guides you back into presence. Through rhythm, sound, and intentional breathwork, the body softens, the mind clears, and the system realigns.

How breathwork transforms the nervous system

Your breath directly shapes your stress response, energy, and emotional balance. Here's what shifts inside your body.
Sympathetic → Parasympathetic Shift
Slow, rhythmic breathing moves the body out of stress mode and into regulation.
CO₂ Tolerance
Better CO₂ control reduces panic signals and stabilizes emotional reactivity.
HRV Improvement
Higher heart-rate variability is linked to calmer mood and better resilience.
Vagal Tone Activation
Breathing stimulates the vagus nerve, supporting deep relaxation and clarity.

Session reflections

“The Frequency method helped me move out of constant fight-or-flight. My anxiety has softened, my sleep improved, and I’m finally able to regulate in moments that used to overwhelm me.”

“The guided rhythms helped me release emotions I didn’t even realize I was holding. Vivian creates such a safe, grounded space — it feels like my whole system finally knows how to exhale.”
Daniel Mercer
“I’ve tried many modalities for stress, but nothing has shifted my nervous system the way these breathwork sessions have. After each class I feel lighter, clearer, and more connected to myself than I have in years.”
