Alternate Nostril Breathing

Summary

Alternate-nostril breathing (nadi shodhana) is a calming, low-risk practice that works — but it works because it *is* slow, paced nasal breathing, not because of anything special about switching nostrils; the parasympathetic effect is well-established and shared with resonance breathing, the protocol-specific blood-pressure and anxiety findings are real-but-thin, and the yogic "balances your left/right brain and purifies your energy channels" story is not supported and should never be stated as fact. ---
