The vagus nerve is the conductor of the orchestra of the human body: signals travel between the organs and the brain, carrying information about the state of the body and telling if something needs attention. Its full role in the functioning of our body has long remained a mystery. In this book, Dr. Nawaz Habib reveals how the vagus nerve regulates the functioning of the heart and lungs, intestines and kidneys and other organs, what happens if it stops working correctly, and how you can improve its functioning. Attention! The information contained in the book cannot serve as a substitute for medical advice. You should consult with a specialist before taking any recommended actions.
