Imagine a breathing technique that can increase oxygen uptake and delivery to the cells, improve blood circulation, and unblock the nose. Perhaps it can help open the airways of the lungs, enhance blood flow and oxygen delivery to the brain, improve sleep, and bring calmness to the mind. It might even restore bodily functions disturbed by stress, build greater resilience, and help you to live longer. You might think this description sounds farfetched. But it isn’t.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

Wim Hof has a message for each of us: “You can literally do the impossible. You can overcome disease, improve your mental health and physical performance, and even control your physiology so you can thrive in any stressful situation.” With The Wim Hof Method, this trailblazer of human potential shares a method that anyone can use - young or old, sick or healthy - to supercharge their capacity for strength, vitality, and happiness.

Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our forbears? Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology?

The health you enjoy today, and for the rest of your life, begins with your next breath. In fact, breathing is so crucial to your body's ability to heal and sustain itself that Dr. Andrew Weil says: "If I had to limit my advice on healthier living to just one tip, it would be simply to learn how to breathe correctly."

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

People are less in touch with their bodies - and especially their breathing - than ever before. Ironically, athletes and others who pride themselves on taking care of their bodies actually put themselves at greater risk. Why? Because they’re asking their body to take on next-level demands, but failing at life’s most essential skill: efficient breathing.

Holotropic means "moving toward wholeness," from the Greek holos (whole) and trepein (moving in the direction of). The breathwork utilizes the remarkable healing and transformative potential of non-ordinary states of consciousness. These states engender a rich array of experiences with unique healing potential - reliving childhood memories, infancy, birth and prenatal life, and elements from the historical and archetypal realms of the collective unconscious.

Thrive or die: That's the rule of evolution. Despite this brutal logic, some species have learned to survive in even the most hostile conditions. Others couldn't - and perished. While incremental genetic adaptations hone the physiology of nearly every creature on this planet, there's another evolutionary force that is just as important: the power of choice. In this explosive investigation into the limits of endurance, journalist Scott Carney discovers how humans can wedge control over automatic physiological responses into the breaking point between stress and biology.

Deep is a voyage from the ocean's surface to its darkest trenches, the most mysterious places on Earth. Fascinated by the sport of freediving - in which competitors descend to great depths on a single breath - James Nestor embeds with a gang of oceangoing extreme athletes and renegade researchers. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and other strange phenomena.
