The Big Red Rooster White Noise Sound Machine is so relaxing and helps me to fall asleep at night. It has six different natural sleep sounds. I have to have background noise to fall asleep easily or else I'm up all night. I feel this makes me sleep more soundly. I leave it on all night, but you can set a timer on it if that isn't your preference. I love that this is portable and can be taken when out of town.
