Why You Might Need More CO₂ — Not Less
Hi Reader,
💡 Today’s Niblit: In his book “Breath,” James Nestor offers a counterintuitive perspective on respiration. He says a little extra carbon dioxide in our system may actually benefit our health.
🔑 Key Insight: We often think of carbon dioxide (CO₂) as a waste product to be expelled, but it plays a crucial role in our body’s functioning. CO₂ helps release oxygen from hemoglobin in our blood, allowing it to be used by our cells. It also helps regulate our body’s pH balance and influences our breathing rate.
Think of CO₂ as a key that unlocks oxygen from your blood. Without enough of this key, oxygen remains bound to hemoglobin, unable to reach the cells that need it. This is why over-breathing, which expels too much CO₂, can actually lead to feelings of breathlessness and anxiety.
Understanding this balance can transform how we approach breathing. Slightly elevated CO₂ levels can improve oxygen delivery to tissues, enhance athletic performance, and even help manage conditions like asthma and anxiety.
🦉 Nibble of Wisdom: “Carbon dioxide is, in fact, a more fundamental component of living matter than is oxygen.” – James Nestor in “Breath,”, quoting scientist Yandell Henderson
🛠️ Practical Tip: Practice slower, lighter breathing to maintain slightly higher CO₂ levels. Aim for about 5.5 breaths per minute: that’s about 5.5 seconds for inhalation and 5.5 seconds for exhalation.
🚀 Quick Action: Take a normal breath in, then exhale and hold your breath comfortably for as long as you can. This brief CO₂ accumulation can help reset your breathing and demonstrate the feeling of healthy CO₂ levels.
🔍 Further Exploration:
- Notice how you feel after sighing or yawning. These actions release CO₂ — do you feel the urge to take a big breath afterward?
- Try box breathing (inhale for 4, hold for 4, exhale for 4, hold for 4) and observe how it affects your sense of calm and focus.
- Research the Buteyko breathing method, which emphasizes maintaining healthy CO₂ levels through controlled breathing.
🎬 Wrapup: Remember, breathing isn’t just about getting oxygen in — it’s about maintaining a delicate balance of gases in our body. By understanding and working with your CO₂ levels, you can unlock better health, enhanced performance, and a greater sense of calm. Your next breath could be the start of a more balanced you!
