Re: How long do affects last for?
Hi bella,
the links I provided in my previous post were my own article from the "Best Years in Life" website, on the highly beneficial effects of Vitamin D3 on the body from sun exposure and supplements, and Sheltons specific links on sunlight and sunbathing from his online book. I would read those links very carefully, and you will learn a great deal from them, as I did originally.
More information for you on the adverse effects of sunblock..............

Canada has a similar climate to us here in the UK: not a lot of sun in the short summer, and long cold winters, so sun-exposure is limited and can therefore be very difficult to receive the benefits we need. However, there is a great deal of benefit from light exposure on the skin, even if that is not direct sunlight.
The main thing is to limit your full-body sun exposure to the cooler times of day and avoid the "heat" of direct sunlight on your skin where possible AND build up that exposure as I have described in my last post.
If you need to avoid over-exposure then you will need to "cover-up" with suitable headgear and light clothing, especially WHITE clothing as this reflects the heat and the light to a certain degree.
In the Winter months, where I am unable to receive the benefits of sunshine, I take a high quality natural supplement of 2000iu's of Vitamin D3 per day: something that not everyone here will agree with (I can hear Andrew moaning already), but you have to bear in mind that the recommended dosage of 2000ius per day in the winter, has been reported to prevent 77% of ALL cancers in clinical trials. It has also been reported from several well respected sources, that most people are Vitamin D deficient.
