176: The Top 7 Habits Sabotaging YOUR Vagus Nerve

In this episode of the Health Upgrade Podcast, I dive into the common everyday habits that quietly sabotage your vagus nerve health. While many people try to add practices like cold plunges and breathwork, I explain why removing certain negative behaviors may be even more powerful for optimizing your nervous system.

I explore the top seven habits that can keep you stuck in a sympathetic, stressed state: alcohol consumption, late-night eating, sedentary living, evening screen time, unhealthy stress coping, mouth and upper chest breathing, and chronic sleep debt or irregular sleep timing. I break down the science behind how each habit undermines vagus nerve function and share easy, practical steps to start shifting towards better health right away.

If you’re ready to feel your best, here’s my challenge for you: pick one sabotaging habit from the list and subtract it for just a week. Notice what happens to your heart rate variability and overall well-being. Share your experiences with me, and let’s keep the conversation going toward a healthier, more balanced you!
