* Try nasal irrigation. Flushing your nasal passages with warm salt water or saline can clear them of excess mucus and lurking viruses.

* Sip hot chicken soup. This old remedy actually slows the surge of white blood cells that accumulate in bronchial tubes, making symptoms flare. Grandma was right!
