Key Moments
Heart rate control through breathing: inhales speed it up, exhales slow it down
Inhaling expands the lungs and speeds the heart; exhaling compresses the heart, slowing it via the vagus nerve. This mechanical relationship lets you control alertness vs. calm through breath patterns.
"Or I can simply make my inhales more vigorous and my heart rate will speed up. This is an autonomic and automatic relationship between the diaphragm, the lungs, the brain, and the heart."
