It’s 5:00 PM and you’re just coming out of another long meeting. Your chest feels tight. You take a deep breath. One of those big, reaching breaths that feels like you need to push past some invisible ceiling just to get relief. Sound familiar? That big, gulping breath you need is called a sigh—a breath 2-3x bigger than your normal breath size. Now while occasional sighing is normal (your body actually does it automatically every 5 minutes to sustain lung function), when you're doing it every few minutes… it means something’s off. Chances are, you’ve trained your body to over-breathe. (Well, not you exactly. The world we live in, the jobs we have, the foods we eat,…)     Here’s what’s happening: Every time you take one of those big, relieving sighs, you dump excess carbon dioxide (CO₂) from your system. Wait! Don’t write this off as biochemistry nonsense that’s only relevant in the laboratory. This absolutely matters for your daily experience: CO₂ isn't just waste you exhale. It's the key that unlocks oxygen from your red blood cells. When CO₂ drops too low, oxygen gets stuck in your bloodstream instead of reaching your brain and muscles. That's why you feel air-hungry, foggy, and like nothing you breathe is quite...

It’s funny how often people are skeptical about breathwork. Then as soon as I tell them a few facts about how breathing actually works, their whole attitude changes. They’re surprised. Intrigued. Because even though we breathe all day, every day, most of us know shockingly little about it. Here’s one of my favorite “well… did you know…” When we think of breathing, we typically think of the lungs. And while the lungs are a critical organ, they’re just the site where the gas exchange happens. Oxygen in, carbon dioxide out. But… they’re not what drives your breath. The real engine of your breath is in your brain. Deep in the brainstem, there’s a tiny cluster of neurons called the preBötzinger complex. It’s this group of neurons that generates the rhythm of your breath automatically, moment by moment. Here’s why this is so cool: The brain-breath loop is bi-directional. Your brain influences your breath. Your breath influences your brain. Meaning: Change your breathing pattern, and you change your brain activity. One of the most powerful ways to do that? Slow, nasal breathing. A few things happen when you breathe slowly, in and out through the nose: For one, you’re dialling up your prefrontal cortex. That’s the part of your brain that helps you focus, regulate emotions, and...
