Our breathing can help us lose weight, positively influence our overall health, and even extend our lives. Those who breathe correctly are more self-confident and can focus better. This book aims to reintroduce us to the lost art of proper breathing. James Nestor meets leading scientists at Harvard and studies the effects of breathing difficulties. He brings us insights from swimming coaches as well as from Indian mystics and strict Russian cardiologists to demonstrate what breathing can trigger in our bodies.
