I'm not big on medical self-help books, that oh-so-popular sub-genre of a popular genre. If someone has to resort to writing a best-seller rather than going down the much less sexy (and lucrative) route of double-blind experiments and the scientific method, if someone tells anecdotal tale after anecodotal tale, however fascinating, then I start to worry, I start to get suspicious, especially where large royalty advances are involved.
And if Product X or life-habit Y really is a panacea and the cure for all known ills, then it would probably be much better-known and already integrated into mainstream medical practice, wouldn't it? If something looks like snake oil and smells like snake oil ... well, you know the rest.
But occasionally something comes along under the radar. This particular something was suggested to me by my daughter, who has a higher degree in biology and is a pretty smart cookie. She's also a fellow skeptic, and I have a lot of respect for her opinions.
Anyway, pre-amble aside, I am currently reading Breath by James Nestor. Mr. Nestor is not a medical practictioner; he's a journalist and someone who has a long history of health issues which he claims to have miraculously cured - red flags straight away for me. But his work does seem to be pretty thoroughly researched, and replete with endless references and sources. His prose is accessible and compelling. And he's not actually selling anything, maybe apart from media appearances, professional speaking engagements, and his hosted retreats and classes... So actually he is selling something, I guess, but, on the strength of my daughter's recommendation, I have persisted with Breath.
Nestor does indeed present correct breathing as the elixir of life and the single solution to conditions as varied as ADHD, hypertension, hypotension, asthma, pneumonia, emphysema, insomnia, sleep apnea, scoliosis, obesity, even cancer. He, and many of the practitioners and other people he quotes, claim that it can add decades to life spans, and coax significantly improved performances out of athletes and opera singers alike.
He approaches his life-changing revelations in the tried-and-tested journalistic manner, with dramatic "personal sory" anecdotes, and his own health issues, his academic study participations, and his apparent Paulian conversion, very much take centre stage. He draws some pretty extreme and far-reaching conclusions from his experiences and his research, though. And hey, who wouldn't like to believe that something as simple as breathing through your nose might be the solution to so many societal ills and life-changing illnesses?
So, am I convinced? The jury is still out. I might try some of his exercises, a little self-experimentation of my own (although my own medical issues are not particularly bad or life-changing at this point). I do remain a bit skeptical, though, particularly about the sheer breadth of Nestors's claims.
Nestor makes some extraordinary claims, so this requires extraordinary evidence, in my view. He does provide some evidence, but some of it dates back to the 1960s or the 1930s or the 1900s (and some of it MUCH older than that). Some evidence is very limited in scope, and some is definitely in the realm of the anecdotal. When he starts to tie in religious prayer and chants, Shakespeare's iambic pentameter, and ocean swells, for example, he is in the realm of book-padding and my eyes start to glaze over. It detracts from his main arguments, if you ask me.
Yes, it makes some common sense to me that breathing through the nose and slowing down breathing would be beneficial, for a whole host of reasons. But let's not make this all-encompanssing and world-changing.
