Sundowning Explained: Why 4:47 PM Changes Everything

It's 4:47 PM. Your person was fine an hour ago. Now they're pacing, agitated, asking to "go home" — and you're standing in the living room of the house they've lived in for twenty years. This is sundowning. It has a name. It has a mechanism. And almost nobody explains it the way it deserves to be explained. In this video, I break down what sundowning actually is, why it happens (hint: a tiny cluster of cells called the suprachiasmatic nucleus), and the four interventions with the strongest peer-reviewed evidence behind them. Every claim in this video is backed by published research.
