This inspiring sheepherder says he doesn't wash his wool because he wants to retain the Vitamin D from the lanolin in the wool. He felts it and wears it next to his skin. He mentions washing it in cold water only at some point. I wonder how long the vitamin D is retained in the wool he is wearing and if this is something you could do in winter rather than take supplements?
