https://bengreenfieldfitness.com/breathepodcast In the past several months, I've taken a deep, deep dive into breath work. Sure, in the past years I've written articles on everything from , to how to , to to to to the during both exercise and sleep... ...but lately, I've been making a very concerted effort to consistently do deep nasal breathing, rhythmic breathing and breath hold tactics during walks, weight training sessions, road trips and beyond. And by concerted, I mean consistently, every day, until these forms of breathing become fully automatic. In her new book "" my guest Dr. Belisa Vranich explains why breathing is so crucial for optimizing brain and body performance, and she delves into one of the most comprehensive treatises of practical breathing tactics that I've ever read (the other best book on this topic is "" by Patrick McKeown, who I'm also getting on the podcast soon). She highlights the results she's seen in her research and in her own patients, including... Insomnia? Gone. Anxiety? Gone. All without medication. Unpleasant side effects from blood pressure pills? Gone. A cheap and effective way to combat cardiovascular disease, immune dysfunction, obesity, and GI disorders? Yes. Sounds too good to be true? Contemporary science confirms what generations of healers have observed through centuries of practice: Breath awareness can turn on the body’s natural abilities to prevent and cure illness. The mental and physical stresses of modern life, such as anxiety, frustration, sexual dysfunction, insomnia, high blood pressure, digestive woes, and immune dysfunction can all be addressed through conscious control of your breath. In addition, it can increase energy, accelerate healing, improve cognitive skills, and enhance mental balance. Yet most of us stopped breathing in the anatomically “right” way, the way to take advantage of these benefits, when we were four or five years old. We now mostly breathe in a way that is anatomically incongruous and makes for more illness. But in the book "", Dr. Vranich shows readers how to turn back the tide of stress and illness, and improve the overall quality of their life through a daily breathing workout. In a fascinating, straightforward, jargon-free exploration of how our bodies were meant to breathe, she delves into the ins and outs of proper breathing. By combining both anatomy and fitness with psychology and mindfulness, Dr. Vranich gives readers a way of solving health problems at the crux and healing themselves from the inside out.  is an easy-to-follow guide to breathing exercises that will increase energy, help lose weight, and make you feel calmer and happier.
