Healthy sinuses require adequate ventilation and nitric oxide, which acts as an antimycobacterial against viruses and fungi. Compared to quiet exhalation, humming increases airflow in your air passages and produces 15 times more nitric oxide. Therefore, humming on a regular basis may protect you from developing sinus infections.*
In addition to adding some songs to your environment, humming every day may also help you ward off sinus infections. Start humming your favorite songs today!
