๐ธ A Supple Centre:
Why Polyvagal Theory Supports what Clinical Somatics Always Knew ๐ธ
One of the key insights of Stephen Porgesโ Polyvagal Theory is crucially important for anyone stuck in pain, anxiety, or discomfort:
๐ฅThe messages your body sends to your brain (especially from your gut) matter more to your emotional state, and your levels of stress and tension, than the thoughts sent from your brain to your body.
Why? Only 15โ20% of messages about your environment, and how safe it is, are controlled by your brain, while 80โ85% come from your gut and all the sensors in your body that inform your gut about your environment.
๐ฅ Why does this matter so very much, from the perspective of Clinical Somatics?
Well, it explains a lot!
It's why you can know you're safe (and tell yourself you're safe, repeatedly), but your nervous system keeps you stuck in survival mode โ anxious and on edge, even long after any real threat has passed.
๐ฅ This supports a fundamental insight of Clincial Somatics โ that muscular patterns of contraction don't just cause pain; they actively signal danger to your brain.
In particular, as Thomas Hanna (who developed Clinical Somatic Education) emphasised: โกwhen the muscles in your centre (your โcoreโ) are tight and braced, your brain interprets this as threat. โก
โกYour nervous system does not know the difference between your muscles being clenched tight into a stress pattern out of habit, and them clenching tight into a stress pattern because a sabre-toothed tiger just walked out in front of you!
๐ฎ All it knows is that those clenched muscles mean youโre under threat.
This is why humans can't simply โlet goโ of anxiety, trauma, fear, or chronic pain through willpower alone, nor through talk therapy or somatic sensing alone.
๐ฅฐThat's why my work focuses on creating a soft, flexible, supple somatic centre.
