28-Day Vagus Nerve Reset: Daily Exercises to Calm the Nervous System, Improve Your Mood and Cognitive System

This book helped me a lot. Especially when I read about how just humming daily can help reduce stress and inflammation in our bodies. And I also forgot to mention in my video, this book also talks about cold therapy and how it helps reset our vagus nerve.Most definitely get yourself a copy of this book and you find yourself getting calmer if you practice the exercises.
