Your bedroom should be your sanctuary from the cold, harsh, and, yes, sometimes dry realities of the world. If you're looking for a more comfortable night's rest, it's worth investing in a humidifier. The best models for this kind of use should balance compact size, low operating noise, and a runtime sufficient for the entire night, so you never need to wake up and refill the tank. That said, there's no one-size-fits-all solution. The best option depends on your budget, the space you need to humidify, and whether you want a cool or warm mist unit.
