The Quiet Power of Humming: What It Reveals About Your Sinuses
TL;DR Humming briefly boosts nasal nitric oxide —an antimicrobial, airway‑supporting gas produced in the sinuses—by about fifteenfold. Research shows this surge only happens when sinus passages are open, making humming a simple, noninvasive indicator of sinus ventilation. It’s useful for detecting obstruction but claims of humming as a sinusitis treatment remain unverified due to the absence of clinical‑trial data. The Power of Nitric Oxide – Health Benefits Through Nasal Breathing and Humming (YouTube link ) Surge in Nitric Oxide Puts Humming in the Spotlight A landmark 2002 study showing that humming can raise nasal nitric oxide roughly fifteenfold has since become a touchstone in sinus research. The work by Swedish scientists Eddie Weitzberg and Jon Lundberg opened the door to using a simple vocal maneuver as a window into sinus ventilation and obstruction. Boosting nasal nitric oxide has emerged as a straightforward way to reinforce the body’s natural respiratory defens...
