“It turns out that when breathing at a normal rate, our lungs will absorb only about a quarter of the available oxygen in the air. The majority of that oxygen is exhaled back out. By taking longer breaths, we allow our lungs to soak up more in fewer breaths.”
― James Nestor, Breath: The New Science of a Lost Art

“The right nostril is a gas pedal. When you’re inhaling primarily through this channel, circulation speeds up, your body gets hotter, and cortisol levels, blood pressure, and heart rate all increase. This happens because breathing through the right side of the nose activates the sympathetic nervous system, the “fight or flight” mechanism that puts the body in a more elevated state of alertness and readiness. Breathing through the right nostril will also feed more blood to the opposite hemisphere of the brain, specifically to the prefrontal cortex, which has been associated with logical decisions, language, and computing. Inhaling through the left nostril has the opposite effect: it works as a kind of brake system to the right nostril’s accelerator. The left nostril is more deeply connected to the parasympathetic nervous system, the rest-and-relax side that lowers blood pressure, cools the body, and reduces anxiety. Left-nostril breathing shifts blood flow to the opposite side of the prefrontal cortex, to the area that influences creative thought and plays a role in the formation of mental abstractions and the production of negative emotions.”

“To put Göbekli Tepe in context, its megaliths predate Stonehenge by at least six thousand years. They predate the first literate civilizations of Egypt, Sumer, India, and Crete by even more. Unearthing this kind of Stone Age sophistication so deep in our past is like finding out your great-grandparents have been secretly coding apps and trading cryptocurrency behind everyone’s back.”

“Each breath we draw in should take about three seconds, and each breath out should take four. We’ll then continue the same short inhales while lengthening the exhales to a five, six, and seven count as the run progresses.”
