Andrew, i was interested in this link too, and saved it in my favourites to read later. The title 'fasting and sunbathing'made me laugh, as i look out on a grey english sky. I kept hearing about natural hygiene principles and didn't really know what everyone was on about. Washing, brushing teeth? LOL
I haven't read it yet but read some of the headings. Coconut oil is good for sunbathing, but he may even suggest that. It doesn't block the beneficial rays.
