Description
Your gut hosts around 500 million neurons—enough to form what's called the Enteric Nervous System (ENS), commonly nicknamed your "second brain." This vast neural network operates independently, managing digestion, emotions, and even influencing your mood. Amazingly, about 90% of the body’s serotonin, a critical neurotransmitter that regulates mood and anxiety, is produced here—not in your head! Communication between your brain and gut is continuous, subtly affecting your feelings, intuition, and mental well-being. This lesser-known brain-gut connection explains the butterflies in your stomach when you're nervous or that gut feeling you can't ignore.
Want to keep listening with the screen off?
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).
