#67 - The Nerve That Changes Everything (and How to Activate It Daily)

Your nervous system has a master switch. It's called the vagus nerve - and when it's toned, everything changes. Your mood. Your resilience. Your ability to feel present, connected, and like yourself.

In this episode of Alignment by Tuva, we go deep into the science of the vagus nerve and what actually shifts in your body, mind, and life when you start activating it daily.

You'll learn:

• What the vagus nerve is and why it's the most important nerve in your body
• Polyvagal Theory (Stephen Porges) and the three nervous system states - ventral vagal, fight/flight, and freeze
• Why chronic stress, people-pleasing, and emotional suppression lower your vagal tone over time
• The gut-brain axis: why 80% of vagal signals travel from your body to your brain (not the other way around)
• 5 science-backed daily practices to tone your vagus nerve: breathwork, humming, cold exposure, somatic shaking, and co-regulation
• What high heart rate variability (HRV) actually means and how to build it naturally

Whether you're new to nervous system work or already deep in the somatic healing world, this episode will give you both the science and the practices to start shifting your baseline - from survival mode to genuine regulation.
