Vitamin D and sun, too much or too little?

Vitamin D and sun, too much or too little?

I've read lots of research recently on how our modern fear of skin cancer is causing widespread vitamin D deficiency (and suffered from this personally) because we slather ourselves in SPF whenever we go outside which stops the sunlight stimulating the skin to make Vitamin D. Apparently although this decreases cases of skin cancer, it lowers the body's immunity and this can actually increase cases of other types of cancer.

I have just come back from my summer holiday where I could feel my body literally drinking in sunlight and making Vitamin D after being covered up all winter. But now I am back, I can see that my hyperpigmentation is worse than before. So I've set out to find out: how much sun do we really need to make vitamin D? And are there best practises to reduce the risk of sunlight exposure?

I downloaded a clever little app for my iphone called d-minder which tracks vitamin D exposure. It knows your location so it can figure out approximate UV values and you tell it how much bare skin is exposed. It then times your sun exposure and calculates how much vitamin D you are making which is really useful! Particularly in the late Spring or early Autumn in the UK when you want to ensure your Vitamin levels stay high (between October and March you can't make Vitamin D in the UK as the sun is too low so supplements are the way forward).

It seems to be safest to get exposure in the morning or late afternoon when the sun isn't as strong. And as we get older we need more and more sun exposure because our conversion rates slow. So a 20 year old might only need 10 minutes a day but a 60-80 year old might need up to an hour.

If there are particular areas of your body (such as your face) that you don't want to expose, by all means use an SPF if you are getting adequate safe sun exposure on the rest of your body. This could be a mineral based powder or a clear mineral based cream. (We are working on an SPF which is truly fabulous! Hopefully it will be available by next summer).

And if you have managed to overdo it like I did, you could consider using our Illuminate serum and Vitality Mask to limit the damage to the skin and reduce the appearance of hyperpigmentation. But it is better not to overdo it at all if you can avoid it, since some damage is unavoidable.
