This video is an ASMR video where you can enjoy the sound of the river (the babbling of the river) and the voice of the birds (the chirping of birds) that improve your concentration when you are watching or listening.

The sound of flowing water contains a waveform called "1 / f fluctuation" that has the effect of relaxing the human mind, and is said to be effective in relieving fatigue and relieving stress.

In addition, water is said to have a healing effect visually, and the pure image of flowing water and the sparkle of light calm and soothe the viewer's mind.

✅ When you want to concentrate on work such as studying
✅ When you want to put your baby to sleep
✅ When you want to sleep but have difficulty sleeping due to insomnia
✅ When you want to get rid of your daily fatigue and stress and relax

I hope you can take advantage of this video at such times.
