Humming and sinus problems
New York Times, By Anahad O’Connor
Dealing with a cold is bad enough, but when it leads to a sinus infection, the misery can double. Some researchers have proposed a surprising remedy: channeling your inner Sinatra.
Sinus infections — which afflict more than 37 million Americans every year — generally occur when the lining of the sinuses becomes inflamed, trapping air and pus and other secretions, and leading to pain, headaches and congestion.
Because the inflammation is often caused by upper-respiratory infections, people with asthma and allergies are more vulnerable than others to chronic sinusitis.
