2. Gargle Salt Water
My doctor is certainly not alone in her recommendations for a salt water gargle—one 1/2 teaspoon salt dissolved in an 8-ounce glass of lukewarm water to relieve a painfully inflamed throat and clear mucus due to a cold. In fact, a randomized study published in The American Journal of Preventive Medicine, recommends gargling salt water as a precautionary cold and flu method. Findings showed that out of 400 participants, half gargled saltwater daily, for 60 days during cold and flu season, and suffered a 40 -percent reduction in upper respiratory tract infections vs. those who didn’t use the salt water gargle.
