Hum before you blow!
That’s because hard blowing can trigger “reflux nasal congestion” – or swelling of the sinuses that can trap infection-causing mucus and keep you sick longer… That’s according to ear, nose and throat doctor, Jordan Josephson.
Instead, hum in a low tone. The vibrations will stimulate the hairs in your nose, helping them whisk away mucus down the back of your throat. Then, gently blow your nose to clear out the debris.
