Perhaps you have had a relaxing experience where you could relax your shoulders by listening to the sound of the river (the sound of a gurgling river).
The sound of flowing water contains a waveform called "1/f oscillation" that has a relaxing effect on the human mind, and is said to be effective in reducing fatigue and reducing stress.
Additionally, water is said to have a visual healing effect, and the pure image of flowing water and sparkling light will soothe the viewer's mind.
In this channel, we will post videos related to "Healing Water Sounds" which are recommended for people who want to focus on work such as studying, reading, sleeping and meditating.
