Understanding Tetany in Breathwork: A Scientific and Energetic Perspective
Experiencing tingling or hand cramps during breathwork? Learn what tetany is, why it happens, and how to respond. Explore both the science and energetic meaning of tetany in breathwork.
When My Hands Curled and I Couldn’t Stop Them
The first time I experienced tetany during breathwork, I honestly thought “oh no!” My hands curled in, my fingers locked, and a wave of tingling moved up my arms like electricity. I was not too surprised but a little anxious about what I was experiencing. Then I remembered what I now tell to my clients: This is your body responding, not malfunctioning. I softened my breath, grounded my feet, and witnessed the tight wave passing.
Within minutes, everything returned to normal except my internal awareness, which had just experienced a new perspective and definition of trust.
That moment taught me something I share with my clients and friends. Tetany is not a sign of harm. It’s a sign of movement.
What Is Tetany?
If you’ve felt tingling, cramping, or claw-like sensations in your hands, feet, face or other body part during breathwork, you’re not alone. This is known as tetany, a temporary and usually harmless physical response to deep or rapid breathing. What’s happening is breathwork changes the chemistry of your body, particularly through oxygen and carbon dioxide exchange. As carbon dioxide drops, calcium temporarily binds in the blood, reducing its availability to nerve and muscle cells causing our muscles to contract or spasm.
When you breathe more rapidly or deeply than your used to, carbon dioxide levels drop (a state called respiratory alkalosis), which can lead to:
Tingling in hands, feet, arms, or face
Cramping or involuntary muscle spasms
“Clawing” or curling of the hands (carpopedal spasm)
Lightheadedness or a floating sensation
A surge of emotional energy or energetic release
Tetany occurs most often in active breathwork styles, especially those involving sustained, deep, or fast-paced breathing. While these sensations may be new or intense, they are not dangerous especially when experienced within a facilitated, trauma-aware breathwork session. They usually resolve on their own once your breathing returns to a more regulated rhythm.
The Science Behind Tetany: Why It Happens
Breathwork changes your internal chemistry, especially how oxygen and carbon dioxide circulate in the body. Here’s how it works:
1. Respiratory Alkalosis
When we breathe rapidly or deeply for an extended period, we exhale more carbon dioxide than the body is producing. This results in something called respiratory alkalosis which is an increase in blood pH (becoming more alkaline) and it is this shift in pH that temporarily impacts the balance of calcium in the body.
2. Calcium Imbalance (Hypocalcemia)
Calcium in the bloodstream exists in two main forms: bound (attached to proteins) and free/ionized (active and usable by the body). When blood becomes more alkaline (due to reduced CO₂), more calcium binds to proteins, reducing the amount of ionized (free) calcium available for muscle and nerve function.
This temporary hypocalcemia (low ionized calcium) is what triggers increased excitability in nerve and muscle cells, resulting in the classic signs of tetany.
3. Hyperexcitability of Nerves and Muscles
Low ionized calcium lowers the firing threshold of nerves. This means muscles may contract involuntarily or become overly sensitive causing tetany symptoms.
4. Symptoms Are Temporary
Tetany during breathwork is temporary, reversible and resolves on it’s own as carbon dioxide levels stabilize and calcium ionization rebalances, usually within minutes of slowing your breath.
Is Tetany Dangerous?
In healthy individuals engaging in guided breathwork, tetany is not dangerous, although it can feel intense or unfamiliar. It’s more of a physiological response than a pathological one.
However, if you have a medical history of:
Calcium or electrolyte imbalance
Chronic respiratory issues
Panic disorder or anxiety-related hyperventilation
…it’s important to approach breathwork gently and with support.
The Energetic Perspective: Tetany as Movement, Not Malfunction
Breathwork isn’t just physical it has an energetic, emotional, and spiritual component, meaning tetany may not only be a bodily response, but also a sign of an energetic movement or release. In energy medicine, tetany may occur when prana (life force) begins moving through previously blocked areas in the body. These could include chakras, nadis, or meridians where unexpressed emotion or energetic tension has been stored.
From this viewpoint, tetany may signify that something within you is being activated, released, or unblocked.
What to Do if You Experience Tetany During Breathwork
Knowing the scientific cause of tetany can help demystify the experience. Reminding us that our bodies are intelligent and responsive and sometimes, intense sensations are simply signs of deep shifts in chemistry and energy, not signs of danger. You are not broken. You are unwinding, something is moving.
If you feel tetany arise in your session, here’s how to support yourself:
1. Soften Your Breath
If the sensation becomes too intense, return to gentle, slower breathing. Inhale softly and slowly into the belly and exhale fully through the mouth. This will help restore carbon dioxide levels and nervous system regulation.
2. Know That You Can Always Pause
This is your breathwork session. You can always return to nose breathing or slow your breath. Breathwork is about listening to and respecting your body, not pushing through discomfort.
3. Stay Curious, Not Afraid
Fear typically adds tension, curiosity allows energy to keep flowing. Remind yourself: This is temporary. If I am uncomfortable, I can slow by breath, my body knows how to process this and return to balance.
4. Move or Shake Gently
Movement can help disperse energy. Wiggle your fingers and toes, gently stretch, rotate your wrists or ankles, or roll your shoulders to help release tension.
5. Ground Yourself
If you’re feeling floaty or ungrounded, place your hands on your thighs or the earth, focus on your feet, drink a small sip of water.
Can Tetany Be Prevented?
You may or may not experience tetany depending on your breathwork intensity or style, emotional state, hydration levels, and/or sensitivity.
To minimize tetany:
Stay well hydrated (tetany is more likely with electrolyte imbalance)
Consider a light magnesium rich meal or supplement beforehand
Let your breath build gradually, no need to start intensely
Welcome your emotions, instead of resisting them
Remember, if tetany happens during your session it may simply mean you are activating stored patterns, physically and/or energetically, and inviting them into motion and eventual release.
You Are Not Injured You Are Unwinding
Tetany may be unexpected, but it is not harmful. It is a natural part of the breathwork process, showing you that your body is releasing tension and your energy is moving. Breathwork meets you exactly where you are, and your breath will never ask you to go anywhere you’re not ready to go. It invites us into places we rarely touch with words. Sometimes, the body responds with tingles, tightness, or tremor like sensations not to scare us, but to release something that was never meant to be held forever.
Tetany is not a sign of injury.
It’s a sign of release.
Of unwinding and opening.
So, if your hands curl or your body tingles, pause, breathe, and remember: You are not broken. You are unwinding.
If you’ve experienced tetany and want to learn more or share what came up, I invite you to reach out or bring it to your next session. Your body has wisdom to share. Let’s listen together. At Compass of Compassion, I believe understanding what’s happening in your body is an important part of feeling safe, empowered, and supported during your breathwork and healing experience.
In Compassion,
