I want to do some experimentation with breath rates. In the mornings strap on a heart rate monitor, record my beginning heart rate, do 15 minutes of breathing with a specific rhythm and record it again. I'd like to do 16-16 even in/out breath, and 8 - 24 - 16 retention style breathing.
Each day do one and record. Every third session do control, listening to music or just resting to see how it affects my heart rate. Try to get a few cycles of data and see what results I have. Maybe I shouldn't have any expectations, but I'm guessing the retentive style breathing will result in a lower heart rate.
Anyone else have thoughts on Body hacks/experimentations? Or want to join in on this one?
