As we all know, there is no cure for the common cold. All that we can do is endure the unpleasant symptoms until we feel back to normal. A humidifier in the bedroom while you sleep keep nasal passages and the throat moisturized, and moisturized nasal passages heal faster. Additionally, to ease sore throats and stuffy noses, the supplement of eucalyptus essential oils can create a soothing mist for when you sleep. Be advised, however, that only some models of humidifiers are suited for essential oils and could damage your unit if they are not. Before use, be sure to read the owners manual to ensure essential oils are safe to use for your unit.
