Nadi Shodhana is a breathing yogi technique known as alternate nostril breathing that can decrease your resting heart rate in just six weeks.
The practice of breathing through one nostril and then the other awakens energies in the Ida and Pingala nadis, secondary chakras
that are located in the left and right nostrils. They are associated with the left and right brain, and also with the
parasympathetic and sympathetic nervous systems and their regulations.
