5 Fun Facts about Breathing

5.) The Death Zone may be a myth, or — probably more accurately — everyone may have their own personal death zone:

It’s widely stated as fact that above 8,000 meters (26,000 feet) every human being is dying, no human can acclimatize, and the race is on to get back below that altitude before the body is damaged beyond its ability to repair itself. This hard-limit is widely publicized in reputable, mainstream publications such as National Geographic. There’s a certain logic to such a limit. In response to the diminished pressure of oxygen, the body produces more hemoglobin (that’s acclimatization), but the bloodstream can only take up so much hemoglobin.

Mark Horrell, in his mountaineering blog, challenges the idea of a one-size-fits-all hard limit, and provides anecdotal examples that contradict the 8,000 meter cap.

4.) Sticking one’s face in water allows one to hold one’s breath longer:

Sensory cells in the face and nostrils sense wetness and this sensation triggers a slowed heartbeat (bradycardia) and constriction of blood vessels (vasoconstriction) so as to reduce blood flow to the extremities.

A more detailed explanation can be read here.

3.) Mouth-to-mouth resuscitation works because our lungs only capture about 20% of the oxygen in each inhalation:

If we had super-efficient lungs, our exhalations wouldn’t contain enough oxygen to sustain the patient receiving cardiopulmonary resuscitation (CPR.)

This and many other fascinating respiratory facts can be found on the Crash Course videos on the subject.

2.) In two weeks time the breath you’re exhaling right now will have spread out around the globe.

Sam Kean’s book, Caesar’s Last Breath, discusses this subject in great depth. In fact, the title is a reference to the fact that in each breath it’s likely that one inhales a molecule of Caesar’s dying breath.

1.) When you lose weight, most of it (84%) is lost in exhaled carbon-dioxide:

This may not be a question that ever occurred to you, but I bet you find it fascinating once it’s brought to your attention. It’s not like when you cut 5 kg, there’s a fat pile sitting somewhere. More about this subject can be learned here.

It’s not an exaggeration to say that there is no set of yogic practices with a greater power to transform one’s life than breathing exercises (pranayama.) With this in mind, I’m always on the look out for new sources of insight into breathing – be it from free-divers, Buddhists, sports scientists, yogis, martial artists, or else-wise. This book provides an overview from a diverse set of experts with descriptions of a number of different breathing practices (e.g. Taoist qi gong, yogic pranayama, a practice for runners, etc.,) but it takes as its central tenet a six-second breath that it recommends as the titular “perfect breath.”

Breathing practices are often underestimated. People, after all, figure that they’ve been breathing every day of their lives, so who can teach them anything on the subject. The idea of reading a book on breathing is right up there with watching the paint dry or the grass grow for excitement. Unfortunately, in parts – many densely pack up front – the authors do too little to dissuade readers of this belief. In early chapters and sprinkled throughout, the book is rife with truisms and banal comments that will leave the rankest neophyte thinking they aren’t going to learn anything of value. That said, I’m glad I kept with it, because the authors convey some powerful insights by telling the stories of people from various walks of life who’ve achieved great things by improving their breath.

The book is organized around a central structure of breathing as a tool for improvement of body, mind, emotion, and spirit. This is sound approach to covering the topic, and the discussion of breath as a means to emotional control is particularly beneficial and welcome. It could be argued that the coverage of the topic of spirituality could have been jettisoned without much loss. The authors talked around the subject in away that was vague and insubstantial. To be fair, they may have been trying to avoid running afoul of individuals who were either secular / scientific (non-spiritual) or who had strong sectarian beliefs on spiritual matters.

The book has seven parts. Part I consists of two chapters that offer an introduction into the topic. These could have been pared down without substantial loss of value. Part II (Ch. 3 – 8) is entitled “Your Perfect Breath” and it discusses developing awareness of breath, body, emotion, spirit, and introduces the fundamentals of how one should breath the “perfect breath.” Part III (Ch. 9 – 12) explores the role that breathing practices can have on improving health outcomes. It’s well established that the body puts healing / rebuilding on hold under high stress, when the sympathetic nervous system is engaged. Breathing practices can help trip parasympathetic (rest and digest) activity. Part IV (Ch. 13 – 15) is of particular interest to athletes and those who want to perform better at some physical or mental activity. In addition to discussing both physical and mental performance, the authors devote a chapter to what is sometimes called Flow (Csikszentmihaly) or The Zone, and how breath can play into quieting the mind to facilitate said state. Part V (Ch. 16 – 19) is about breathing as a means to take control of one’s emotional life. People in the throes of emotional turmoil are unlikely to notice how that turmoil influences their breath, but it has a major impact — and it’s a two-way street, i.e. one can help mitigate excessive emotional response through breath. Part VI (Ch. 20 – 21) is devoted to spirituality and the nexus of breath and prayer or meditation. The final part (Ch. 22) explores the idea of the final breath. I thought this was a valuable discussion, given the tremendous anxiety of coming to one’s last breath and its impact on people’s lives.

There are no graphics in the book. They aren’t greatly missed, but might have been useful in places. (It’s probably more accurate to say the authors could have gone into more depth if they’d used graphics and not stayed in such vague territory.) There is an appendix that lists and briefly describes the included exercises, and the e-book / Kindle version includes hyperlinks to the detailed description in the book’s interior. Having a link to the practices is a useful feature. There is also a short section of recommended readings.

While it took me a bit of time to get traction in reading this book, once I did, I learned a great deal. I would recommend it for anyone who is interested in an overview of breathing practices for health, emotional control, and increased physical performance. The authors transmit expertise from a broad range of experts from various walks of life.
