I’m in a truck waiting to do some work…reading about yoga.

I hope to go home today. I’m not sure when yoga will happen today…work then fly then maybe hours in Nome then home late.
While reading The Science of Yoga…this was interesting,
pp..86-,89 yogis often talk of how fast breathing increases oxygen but in fact it decreases it and changes the oxygen to carbon dioxide ratio in the blood …hmmm
p. 86
The following is within a discussion about fast breathing exercises like Breath of Fire commonly practiced in yoga classes with instructors claiming that it increases oxygen levels in the blood. I known I have done this exercise and have heard this claim presented as the reason why we do it.

“while exhilaration and nerve excitement go up, fast breathing does something else that has critical repercussions for mood, mental outlook, and potentially health-it robs the brain of oxygen.
The reason is that the surge in carbon dioxide causes blood vessels in the brain to contract, reducing the flow of oxygen and producing lightheadedness and perhaps blurred vision….-as crazy as this sounds, as counterintuitive as it seems, as contrary to the teachings of popular yoga is it appears-is that fast breathing lowers the flow of oxygen to the brain, and does so dramatically. Scientists have found that it cuts levels roughly in half. That plunge is why people faint.”
Just another interesting insight from William J. Broad’s book.

Waiting to sample in my truck…

I have challenged myself to do yoga everyday for one year and thought I'd blog about it. I have been practicing yoga on and off and back and forth for about 9 years and I have decided that it is time for me to really delve in and figure out what it's all about, if it is something I want to make part of my life. I also thought this might put some discipline in to my day and be a fun way to express my thoughts and share some pictures that may or may not have anything directly to do with yoga.
