You’ve probably heard some variation of this by now: You can go weeks without eating, days without water, but only minutes with breathing.
But, have you stopped to think about what that really means?
I think we’d all agree that what we drink affects more than just hydration. (For example, weight loss and exercise performance.)
The same goes for eating. You would likely agree that what you eat is important to many aspects of health. For example, sleep and energy levels can be directly impacted by food.
However, when it comes to breathing, this is often overlooked. Most people think breathing is just about getting oxygen. But what if breathing actually limits oxygen?
Breathing: Is it Really About Oxygen?
Almost all “breathing techniques” are centered on oxygen. This makes sense. Oxygen is, after all, our #1 source of energy.
But what happens if we shift our perspective and look at breathing and circulation differently?
In the atmosphere, oxygen exerts a pressure of ~160 mmHg. In our cells, it exerts a pressure of ~5 mm Hg. From the time we inhale to the time the air reaches our cells, the oxygen pressure is reduced by 97%.
Therefore, our intricate oxygen transport system can be viewed as a way to limit the amount of oxygen getting to our cells. [1] Meaning, you can’t breathe more and “super-oxygenate” your body.
(Actually, breathing less is the only way to increase oxygen to your cells. But that only corrects under-oxygenation, it does not “super-oxygenate”.)
Breathing Goes Beyond Oxygen
I don’t think we’ll ever understand all of the functions of breathing. But, just like eating and drinking, breathing has impacts far beyond the obvious. Here are a few other reasons we breathe:
Circulate nitric oxide
Improve sleep
Improve cardiovascular health
Improve autonomic balance
Improve digestion
Increase energy levels (well, this is related to O2)
Synchronize brainwave oscillations
Improve cognitive function
Improve emotional control
Reduce stress and anxiety (or create it, depending on how you breathe)
That’s A Long List
And it should probably be longer.
But here’s the point: Breathing is Fundamental. It’s more important than what you eat, what you drink, or even how you sleep.
But you can’t just ignore these things either. In fact, I believe breathing should support you in your quest to optimize them. Health and well-being are not about any one thing. But, you have to start somewhere. So why not with your body’s most important function?
In good breath,
