Relax and let yourself take some nice deep breaths while we listen to the wonderful white noise of waterfalls and learn some facts about the life cycle of a waterfall. ASMR triggers include nature sights and sounds, soft speaking, and whispering.
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
