Do you know that 90% of your Vagus nerve signals actually go up and not down. Your Vagus nerve is what connects your brain to the rest of the organs in your body - this means that 90% of the signals that your brain processes come from your body, which shows that the health of your body has a massive influence on how you feel.
Nearly everyone I have worked with with an autoimmune, digestive or skin issue initially started with depression, low mood or anxiety as a symptom.
Then, when they fixed their physical health, they also fixed their mental health. This confirms that it is not “all in your head”. So when your body is balanced, your brain can be balanced.
