Manage noise. Some people sleep best in total silence; others need ambient noise to fall asleep. Whatever your preference is, here's how to make it work:
Use earplugs: block out sounds of roommates or neighbors. With them in you should still be able to hear emergency warning systems like a fire alarm. You can buy them at any pharmacy.
Drown out intermittent noises: Use a consistent noise. If you're trying to fall asleep but keep getting interrupted by noises from the street or around the house, try to block them out with a regular noise. Turn on a fan, some music or a white noise machine. These can make a big difference.
Listen to music: Low-volume music that's soothing or familiar can provide comforting background noise while your mind checks out. Instead of putting in headphones, consider turning on the radio or leaving your MP3 player on your nightstand at low volume.
Compile a playlist: If you have an iPod, compile a playlist of relaxing and soothing songs (with little to no lyrics). Avoid songs that you enjoy singing along to, however. Turn the volume down as low as possible but make sure the music is still audible enough to drown out intermittent noises.
Listen to ambient noise: Raindrops, running water, wind, or binaural beats are all sounds that help some people sleep. See if you can download a free app with these features.
