Not Sleeping? 9 Ways It Could Be Your Bedroom's Fault

Another important factor that could interrupt your sleep quality is intermittent noises at night. "Cars passing on the street, busses zooming by, airplanes overhead, dogs barking, snoring partners — all of these noises have the potential to wake you up at night," says Wong. If your bedroom is in an area prone to intermittent noise at night, she recommends using some sort of white noise, like Marpac Dohm Classic White Noise Sound Machine, $44.95. "White noise creates a consistency in your aural environment that is harder to interrupt, which makes it less likely that you'll wake up in the middle of the night by a passing car or a loud roommate," she says. High-quality earplugs, like Bose Noise-Masking Sleepbuds, $249.95, are another solution, and especially come in handy when you're traveling.
