I found this writing style annoying. For example, this sentence is inaccurate and contains faulty logic: "Of course, there is no scientific evidence that good breathing can provide lasting medical benefits, or else cardio instructors would live forever and never cry."
Once I got past that, I liked the content. I just graduated from a yoga teacher training at Yoga to the People, and we talked a lot about breathing. Pranayama, control of life force, is one of the eight limbs of yoga. YttP is all about collective vibrational breaths, which the yoga teacher cues throughout class (e.g., "Exhale all your air out shhh. Inhale a deep belly breath in. Exhale H-M hmmm.") My friend from YttP who took a class at another studio said that, when she breathed, the instructor asked, “Who is humming??”
As a former fitness trainer, I can attest to the fact that most people do not know how to breathe. And I agree it has a lot to do with stress. What I don’t agree with is spending a lot of money to learn the technique. Any yoga book is a great start. If you like the idea of variety in breathing techniques, there are books on that subject also. If you need physical instruction, you can get that in a yoga class or meditation class that won’t upset your budget. It’s definitely worth the effort to sit and breathe deeply - your body, mind and spirit will rejoice! The health benefits are true.
I guess I'll turn back on my apple watch breathe app...
