6. Scented Humidifier
Battle that dry, stale feeling that the heater brings on during the winter by turning your stove into a makeshift humidifier. Grab a couple of peels and pop them into a boiling pot of water, then turn down the heat to a low simmer. The steam will bring more moisture into the air and the lemon will bring in a zesty, fresh feeling. (Just be sure to watch the stove and not leave it on too long.)
