lights that are overhead that are a little bit softer, of the sort or yellow or reddish tints, would be slightly better, but dim lights that are set low in the room are going to be best

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So, in my house at night, we get red. It's weird, right? It's all red rooms in my house. So, I've put in these zero flicker LEDs. It's an LED, but it's zero flicker LED. It's a film grade LED. And it's a red light. There's no blue in this red light. So, this is a light that's close to the floor. They're dim. And even a bright red light can interfere with your circadian rhythm. It's the brightness of the light and how much blue is in it. But a dim red light close to the floor is the easiest way to still move around and do things in your house at night without negatively affecting your circadian rhythm, negatively affecting your sleep quality.
