Your jaw tension is literally crushing your breathing and destroying your posture from the inside out.
The masseter muscle (your jaw) shares a neurological highway with your diaphragm and pelvic floor they’re all connected through the same fascial chains and nervous system pathways.
Here’s what happens when your jaw is clenched:
•Your diaphragm can’t fully expand, reducing oxygen by up to 30%
•Your pelvic floor compensates by over-tightening, creating lower back tension
•Your entire core becomes rigid instead of responsive
•This creates a domino effect: tight jaw → shallow breathing → weak core → poor posture
The Science: 1️⃣ Trigeminal nerve (jaw) → 2️⃣ Vagus nerve (diaphragm) → 3️⃣ Pelvic nerve → 4️⃣ Postural collapse
With a clenched jaw: Your diaphragm stays elevated, your pelvis tilts forward, creating that hunched-over “tech neck” posture.
With a relaxed jaw: Your diaphragm drops fully, your pelvis stabilizes, your entire spine decompresses.
Most people try to “fix” their posture by pulling their shoulders back. That’s like trying to fix a foundation by painting the roof.
The REAL fix?
Release the jaw tension that’s hijacking your entire breathing system 24/7.
