For fast and effective sore-throat relief, nothing beats an old-fashioned saltwater gargle. Salt acts as a mild antiseptic, and also draws water out of mucous membranes in the throat, which helps to clear phlegm. Dissolve a half-teaspoon salt in a glass of warm water, gargle and spit out. Repeat up to four times a day.
Alternatively, gargle with a baking-soda solution. Dissolve one-half teaspoon of baking soda in a glass of warm water.
Run a cool-mist vaporizer or humidifier in your bedroom. Adding moisture to the air will help keep the air from drying out and prevent the lining of your throat from becoming too dry. If you don’t have a humidifier, place a bowl of water on your radiator or heating vent each night. It will work as well as a store-bought device.
