This album contains the "1/f fluctuation" of natural sounds as well as "1/f2 fluctuation" synchronized with the breathing intervals during deep sleep, which will lead you to an even more "comfortable sleep."
There are no gaps between songs, and the sound naturally transitions from the sounds of birds and insects to the sound of a stream and waves, allowing you to drift off to sleep peacefully without being disturbed by everyday sounds.
An unprecedented sleep support album with a unique fluctuation process that invites relief and rest.
