Vitamin D is not a vitamin | Niklas Gustafson

The wildest part of this isn't any single fact. It's that the fix is free, and that's exactly why you've never heard it framed this way. There's no product in "go outside in the morning." She's right that vitamin D was misnamed, it's a steroid hormone your skin makes from cholesterol and sunlight, with receptors in almost every cell, including the brainstem regions that run your sleep. Which means the two things we've spent fifty years being told to fear, sun and cholesterol, are the raw materials for the hormone behind sleep, immunity and metabolism. Morning light, bare skin, no sunglasses. It costs nothing, and that's the whole problem with it.
