The average person takes 15 to 18 breaths per minute. The optimal range is 8 to 12. That gap — those extra breaths — costs more than most people realise.
What over-breathing actually does
Every time you exhale, you release CO₂. When you breathe too fast, you exhale too much. CO₂ drops below optimal levels. And as we explored in the CO₂ piece — without enough CO₂, oxygen cannot be released from your red blood cells efficiently.
The result: your cells are starved of oxygen even though you are breathing constantly. Your body reads this as stress. Your nervous system activates. Cortisol rises. Focus narrows. Energy drops.
You are not breathing too little. You are breathing too much, too fast, and through the wrong part of your face.
The symptoms nobody connects to breathing
Common signs of chronic over-breathing: persistent fatigue, difficulty concentrating, waking up tired despite sleeping, frequent sighing or yawning, light-headedness, cold hands and feet, anxiety without clear cause, disrupted sleep.
These symptoms are widely treated as separate problems. Supplements for energy. Medication for anxiety. Sleep tracking for fatigue. The root cause — breathing pattern — is almost never addressed first.
Where to start
Slow down. Breathe through your nose. Let the exhale be longer than the inhale. Do this for five minutes and notice what shifts.
The breath is the only part of your autonomic nervous system you can consciously control. That is not a small thing. That is the door.
