Dear Help Sinuses Members:

I thought you might like to know about this research that was
recently reported.

Humming May Help Reduce the Incidence of Sinusitis & Upper
Respiratory Infections

In a study that was reported in the American Journal of Respiratory
and Critical Care Medicine (2002; 166: 144-145), researchers at the
Karolinska Hospital in Stockholm, Sweden found that nitric oxide
levels in the sinuses were 15 times higher during humming than during
normal, quiet exhalations. Nitric oxide (NO) helps to dilate the
capillary beds and increase blood flow. Humming had the effect of
dramatically increasing the gas exchange in the nasal sinuses. If
fact, during normal exhalation the gas exchange between the nasal
passages and the sinuses was about 4 percent. When the volunteers
(all "healthy") hummed, the gas increase incased to about 98 percent.

A poor exchange of gas, as well as poor circulation, in the sinus
cavities, creates an ideal environment for the growth of bacteria and
viruses. And this can quickly lead to infection. Based on the results
of their study, the researchers believe that regular breathing
exercises that involve humming may be able to help reduce the
incidence of sinusitis and infections in the upper respiratory tract.
