Great, article explains a lot that I already knew about in a more technical way. You really explained well the practical reasons of practicing Alternate Nostril Breathing Technique(Nadi Shodhan Pranayama).

Alternate Nostril breathing is a beautiful breathing technique that helps keep the mind calm, happy and peaceful by just practicing it for a few minutes. It also helps release accumulated tension and fatigue. The breathing technique is named Nadi Shodhan, as it helps clear out blocked energy channels in the body, which in turn calms the mind. It is also known as Anulom Vilom pranayama.

(nadi = subtle energy channel; shodhan = cleaning, purification; pranayama = breathing technique)
