Thanks Richard, Dermatologists advise people suffering from skin cancer to cover their skin completely or use high factor sunscreen EVERY 2 HOURS WHENEVER they are exposed to sunshine. However, vitamin-D sufficiency is necessary as part of a healthy lifestyle to prevent or help heal many forms of cancer, including skin cancer. I found through experience that even 15 minutes exposure of my fair skin to midday sunshine in New Plymouth during May, June and July aggravated my skin cancer. That created a dilemma. But I found through experience that I could achieve optimum benefit from sunshine by exposing different sides of my body to midday sun for no more than 6 minutes in summer and no more than 8 minutes in winter. That accumulated a total of 24 minutes and 32 minutes respectively for my whole body. But I avoid the sun or cover up completely on alternative days.
Hi Mike. The exposure regime you describe sounds sensible. With that, your vitamin-D levels should build up substantially over the summer months. Although the winter exposures won't be sufficient to maintain those high levels without some decay, its unlikely they would ever get much lower than the recommended annual mean of 50 nmol/litre. Incidentally, I've added a note to those posts to say the exposure times shown can probably be reduced by a factor of 0.7 (to take account of new work published after our original study). So what was 3 minutes, becomes 2 minutes, etc. But there's still a lot of discussion about this point. The overall message remains the same, but I'll probably update the posts once the dust settles.

Useful post, thank youl
Thanks Melanie .... Hopefully we'll have the real oil soon on the GlobalUV and UVNZ apps.
