This Week In Lights Out: Light, Amino, Hormone, Myth
A hundred lux, 897 participants, one hormone that falls early, and the lab study that ruined the long-weekend lie-in. Everything worth keeping from all of it.
Four issues went out this week, and not one of them asked you to try harder. Every fix was already sitting in the room, on the label, or in your own biology, waiting for somebody to name it.
If you read nothing else before the long weekend starts, read the four cards below. Each one is the piece worth keeping.

Run a two-minute lights-off scan and tape over every indicator LED you find, because 100 lux was enough to shift insulin the next morning.
