How Does A noise sound machine Help Me (or My Baby) Sleep Like A Baby? White noise promotes relaxation prior to sleep by providing a constant, soothing sound for the brain to settle on. This helps quiet the mind and keeps you from focusing on disruptive sounds which interfere with the process of falling asleep. Once you\'re asleep, white noise works all night long to drown out the random noises that would have woken you up - either completely or just as partial \'micro-awakenings,\' which you may not even have remembered in the morning. This means that you sleep more solidly and deeply, and rise feeling more rested and restored. 15 Soothing Sounds The portable sound machines offer White Noise, Rainforest, Thunder, Wind Chime, Fan, Wind, Campfire, Ocean, Seagull, Brook, Birds, Bubble, Typhoon, Rain, Brown noise.
