Japan’s 20-year Ig Nobel winning streak continues thanks to people blowing their noses

Every year, the Ig Nobel Prizes honor unconventional research that sparks both laughter and contemplation. This year's Medicine award, given posthumously to the late Dr. Tokuji Unno and Dr. Hiroshi Yajima, celebrates their 1977 investigation into the art of proper nose blowing. This marks the 20th consecutive year a Japanese researcher has claimed an Ig Nobel Prize.

The duo's study, conducted with volunteers linked to airflow meters and eardrum pressure sensors, revealed key insights into the science of nose blowing. First, they found that the "One-Side Policy" is crucial: blowing both nostrils simultaneously diverts air to the easiest path, leaving the clogged side congested. To clear it, one must block the clear side, generating a high-velocity airstream.

Second, contrary to popular belief, blowing forcefully isn't harmful to the ears. The nasal and middle ear are separate from this equation, with greater airflow velocity actually boosting mucus expulsion efficiency. Lastly, the optimal blow lasts about 1.23 seconds, expelling 1.34 liters of air - roughly a third of one's lung capacity. Sustained, steady breathing rather than rapid, forceful blows is most effective in dislodging mucus deep into the bronchial tubes.

In essence, the next time you reach for a tissue, consider the scientific approach - press one nostril, take a measured breath, and blow long and steady with newfound confidence in the aerodynamics of nasal hygiene.
