What Nobody Told You About Breathing

Your blood oxygen reading can show 99% — completely normal — while your cells are still receiving less oxygen than they need. The missing piece is carbon dioxide. CO2 is not a waste product to exhale away — it is the signal that tells your blood to release oxygen into your tissues. Conscious breathwork retrains this system directly.
Here's something that stopped me the first time I heard it.
Your blood oxygen reading could be 99% — completely normal, nothing flagged — and your cells could still be getting less oxygen than they need. Your doctor would look at your labs and tell you everything looks fine. And you'd go home feeling exhausted, foggy, anxious, and wondering what's wrong with you.
Nothing is wrong with you. There's just a delivery problem that most people don't know exists.
I've told this in sessions and watched people's faces change. Because it explains a lot. The afternoon crashes. The anxiety that doesn't match your circumstances. The sleep that doesn't restore you the way it should. The feeling of doing everything right and still running at a deficit.
Once you understand what's actually happening in your bloodstream, you can't un-see it. And more importantly — you can do something about it.
Why Your Blood Oxygen Reading Doesn't Tell the Whole Story
A blood oxygen reading measures how much oxygen is bound to red blood cells — not how much is actually reaching your tissues. Without sufficient CO2, oxygen circulates through the body but cannot effectively release. You can read 99% on a pulse oximeter and still be running at a cellular deficit. The delivery problem is almost never measured.
Most of us have been taught to think of oxygen as the thing the body needs — and CO2 as the thing it needs to get rid of. Exhale the bad stuff. Inhale the good stuff. Simple.
That framing is wrong, and it matters enormously for how you feel every day.
The body does not automatically deliver oxygen to your cells just because that oxygen is present in the blood. It needs a signal — a specific trigger that tells hemoglobin to let go of the oxygen and release it into the surrounding tissue. That trigger is carbon dioxide. Remove CO2 from the equation through chronic over-breathing, and you've removed the signal. Oxygen is present but inaccessible. Your blood is carrying it everywhere and dropping it off nowhere.
The Rideshare Your Body Has Been Running
Carbon dioxide is not a waste product — it is the signal that tells hemoglobin to release oxygen into surrounding tissue. Without adequate CO2, oxygen circulates in the bloodstream but stays bound. CO2 also keeps blood vessels dilated. When it drops through over-breathing, vessels constrict, blood pressure rises, and the brain registers a low-grade threat.
Think about opening a rideshare app. You see cars roaming the city — moving, present, available — but not going anywhere useful. It's not until someone enters a destination that a car heads toward them with purpose.
That's oxygen in your bloodstream when CO2 levels are too low.
Oxygen is carried through the body by red blood cells. But it doesn't just automatically release into tissues when it arrives. It needs that trigger — a CO2-driven shift in blood pH that prompts hemoglobin to let go. This mechanism, known as the Bohr Effect, was discovered in 1904. Without adequate CO2, oxygen circulates but stays bound. Present in your blood, inaccessible to your cells.
CO2 does something else most people don't know: it is a vasodilator. It keeps blood vessels open and expanded. When CO2 drops — which happens every time you over-breathe — blood vessels constrict, blood pressure rises, and blood flow to the brain and vital organs decreases.
Your body reads that drop as a low-grade threat signal. The stress response activates. The cycle continues.
Most of Us Are Breathing Too Much — Here's What That Actually Means
The optimal resting breathing rate for health and cognitive performance is 3 to 6 breaths per minute. Most adults breathe 10 to 18 times per minute at rest — higher still under chronic stress. That gap keeps CO2 chronically low, the nervous system in a mild stress state, and cellular energy production less efficient than it is designed to be.
At rest, the average person takes somewhere between 10 and 18 breaths per minute. Under chronic stress, that number climbs higher. Most of us are in a low-level state of over-breathing almost constantly — blowing off CO2 faster than the body replenishes it, keeping the nervous system in mild activation, reducing the efficiency of cellular energy production, and never knowing why we feel the way we feel.
This is why conscious breathwork that slows and rhythmically structures the breath — combined with breath holds that allow CO2 to build — is not simply a relaxation technique. It is a physiological retraining. It is teaching the body to:
Tolerate higher CO2 levels without triggering unnecessary stress response
Deliver oxygen more efficiently to the tissues and organs that need it
Regulate blood pressure and blood vessel dilation through CO2's natural vasodilating effect
Downregulate the autonomic nervous system from chronic sympathetic activation toward its natural resting state
Each of those changes is measurable. Each of them affects how you feel every single day.
The One Number Worth Tracking in Your Breathwork Practice
Breath Hold Time — the seconds you can comfortably hold after a normal exhale — is a direct window into your CO2 tolerance and nervous system function. It is personal, concrete, and trackable. Most people who complete 21 days of consistent conscious breathwork practice see their BHT shift meaningfully. That shift is evidence that something real is changing.
One of the first things we do in the 21 Day Awakening Journey is establish your BHT — Breath Hold Time. The measurement is simple: after a normal exhale, hold your breath until you feel the first gentle urge to breathe again. Not a maximum effort hold. Just the first natural signal.
Count the seconds.
That number is a window into your current CO2 tolerance and nervous system function. It is personal, it is concrete, and it is trackable in a way that most wellness metrics are not. Most people who complete the 21-day practice watch it shift meaningfully — sometimes by 10 seconds, sometimes by 30 or more. That shift is not just a number. It is evidence that CO2 tolerance has improved, that oxygen is delivering more efficiently, that the nervous system is operating with a wider margin before it hits the stress threshold.
You feel that difference before you fully understand it. More energy. Clearer thinking. A longer gap between something happening and you reacting to it.
I remember the first time I measured mine seriously — in Ibiza, surrounded by people who had been practicing for years. I understood for the first time why some of them seemed to operate differently in the world: calmer, clearer, more present, more energized. They were not just doing breathwork. They had retrained their biology.
That is what is available in 21 days of consistent practice. Not a feeling that fades when the session ends. A change in your baseline.
You can read more about what that baseline shift actually looks like across three weeks — day by day — in this piece.
Frequently Asked Questions: The Science of Breathing and CO2 Tolerance
What is CO2 tolerance, and why does it matter for how I feel?
CO2 tolerance is your body's ability to remain calm and functional as carbon dioxide levels naturally rise in the blood. Low CO2 tolerance means the stress response triggers too quickly — producing anxiety, over-breathing, poor sleep, and reduced energy. Training CO2 tolerance through conscious breathwork recalibrates this threshold, giving the nervous system more room before it reaches a stress response.
What is the Bohr Effect and what does it have to do with breathwork?
The Bohr Effect, discovered in 1904, describes how carbon dioxide enables hemoglobin to release oxygen into body tissue. Without adequate CO2 — which drops when you over-breathe — oxygen circulates in the blood but cannot effectively reach cells. Conscious breathwork that includes breath holds allows CO2 to rebuild, restoring the delivery mechanism and improving cellular oxygen access.
How does conscious breathwork actually affect the nervous system?
Conscious breathwork directly stimulates the vagus nerve through slow, rhythmic breathing, shifting the autonomic nervous system from sympathetic activation — the stress state — toward parasympathetic rest and recovery. Breath holds add a CO2 training component that lowers the stress response threshold over time. Together, these mechanisms retrain the nervous system's baseline, not just its momentary state.
How do I measure my Breath Hold Time correctly?
Take a normal breath in. Exhale naturally — not forced, not emptied. Then hold your breath and count the seconds until you feel the first genuine urge to breathe. Stop there. That is your BHT. Do not push through discomfort or go for a maximum hold. The first natural signal is the measure. A BHT under 20 seconds generally indicates significant CO2 sensitivity; 40 seconds and above reflects a well-trained system.
Is there a conscious breathwork program near Temple or Belton, Texas, that teaches this kind of practice?
Yes. Energy of Creation is a faith-based wellness nonprofit based in the Temple/Belton area of Central Texas. The 21 Day Awakening Journey — a structured 21-day conscious breathwork conditioning program — runs four times per year and is available online. Super Sunday, our monthly breathwork gathering, is held online the first Sunday of every month and is open globally.
Your Body Already Knows How to Do This
You've been breathing your entire life — about 20,000 times a day. You never had to think about it. But you also never had the information to use it as a tool.
That's what changes when you understand the Bohr Effect, when you start tracking your BHT, when you practice slowing down, extending the exhale, and holding at the bottom — not as a performance, but as a daily retraining. Your body already knows how to do this. It has been waiting for you to give it the right conditions.
Energy of Creation's 21 Day Awakening Journey is where that retraining happens. Guided daily breathwork sessions, three weekly live calls, an eight-lesson pre-course foundation, and a real community practicing in real time alongside you. The May 4 cohort is the final opportunity to join at the founding contribution of $497. Beginning May 5, the program investment moves to $1,497.
All contributions support Energy of Creation, a 508(c)(1)(a) faith-based nonprofit wellness community. All donations are final.
