Most people breathe into their chest instead of their belly, missing the base of the lungs where blood flow is 10 times higher. Nasal breathing and slow, controlled exhales balance oxygen and CO2, reduce anxiety, and change your physiology. Posture matters too: slouching makes you breathe faster and stressed.
There is a science of proper breathing in and out through your nose. Breathe into your belly. Your lungs are like triangles. The bottom of your lung is 10 times more blood flow than the top of your lung. So if you're taking these breaths just up in the top of your chest, it's not getting throughout the rest of your body. If you can breathe down into the base of your lungs, into your belly, much higher blood flow, much higher oxygenation throughout your body, which is going to help you have a proper rate of exhalation. Paradoxically, it's not how much oxygen you have in your blood, it's how much carbon dioxide you in your blood that allows the oxygen to get into your muscle tissue. So when you breathe out through your nose, it's going to have a proper cadence of oxygen to CO2. Slow and in control. Check in with your breath. If you're ever feeling anxious, if you're ever feeling stressed out, if you're hunched over and you're breathing fast, if all you do is switch your posture and then start to breathe slow, one slow, controlled breath, your entire physiology changes.
