Sleep doesn't come easily to everyone. If you're the type of person who drifts off into a deep slumber the second your head hits the pillow, just know that there's a whole other camp of people out there who seriously envy you. It's thought that roughly one in three of us suffer from insomnia and, for those people, ambient noise can be the only way to get those crucial hours of shut-eye at night.
