I've been in the dastardly grasps of my first flu in over 4 years, a most unwanted holiday guest. And because of the combination of colder weather, the heater being on constantly, and the drying effects of cold medication, my nasal passages have been taking a beating. A few friends have mentioned a humidifier comes in handy in easing breathing while ill, but I've been loathe to purchase an appliance which looks like it came from the pages of Skymall (in other words, 99% of the humidifiers on the market). My fav are these ultrasonic cool and warm mist Middle Colors Humidifiers from Japan. At 8-10 hours continuous use, these are ideal for overnight use when you most need a little humidity to ease the mucous membranes. They also look nothing like the drugstore special, and can be used as an aroma diffuser during your more healthy days.
