Nasal breathing, by contrast, produces nitric oxide. This is a molecule that dilates blood vessels and kills pathogens. This increases oxygen absorption by 10-20% and enhances blood flow to the brain. Mental clarity depends on biology more than it does on psychology.

The metabolic cost of mouth breathing: It triggers a chronic stress response, elevating cortisol and contributing to insulin resistance. Your mitochondria become less efficient, shifting to anaerobic metabolism even at rest.

Your nose is a precision instrument with 5 crucial functions: 1. Humidification (prevents dry lungs) 2. Filtration (traps pollutants) 3. Nitric oxide production 4. CO2 regulation 5. Diaphragmatic engagement The mouth evolved for eating, not breathing.

When I had IBS, I discovered that breathing pattern affects gut function too. Mouth breathing activates fight-or-flight mode, shutting down digestive function. Nasal breathing activates the rest-and-digest parasympathetic system, improving gut motility and enzyme production.

My protocol to retrain your breathing: 1) Practice conscious nasal breathing during the day 2) Try the 4-7-8 breathing pattern (4s inhale, 7s hold, 8s exhale) ↓ Mouth taping might work, but who the fu*k wants to put a tape on their mouth?

For advanced optimisation, try these techniques: • Box breathing for focus (4s in, 4s hold, 4s out, 4s hold) ↓ • Alternate nostril breathing for balance • Wim Hof method for immune function

How to know if you're making progress? First, note morning energy levels. Check for dry mouth upon waking. Monitor resting heart rate (should decrease). Measure recovery time after exercise And finally, observe changes in facial tension and posture.

I've coached 1500+ people on health optimisation, and breathing pattern correction consistently produces the most dramatic improvements. You started this life with your first inhale. You'll end it with your last exhale. Therefore, breathing is life itself.

@bensmithlive Dude, first post of yours I’ve seen, might keep an eye on your content. I like the topic, what about your open mouth pose profile pic though ?
