From ancient times to the present day the sun has always been known as the giver of life. However for the last fifty or so years, it has been touted as the evil crusader of cancer!
I fully agree that sunbaking yourself on each side for too long is nothing short of stupid. However I don't think most people who get sun burnt actually go out to get burnt. So we need to be a little more mindful when going out in the sun, timeframes of exposure, and skin type.
Direct sun exposure is essential for the production of vitamin D in the body. We don't get vitamin D from the sun. Most people don't realise that we actually produce vitamin D in the skin via the exposure of our skin to the sun's rays. This is why smart sun exposure is so important.
It's unfortunate that we only seem to hear one side of the story - that is to stay out of the sun and if you do go into the sun, then cover up and lather yourself in the highest S. P. F. sunscreen you can find.
A sunscreen with an S. P. F. of 8 blocks 95% of the skin's ability to produce vitamin D. An S. P. F. 15 or higher takes it from 99 up to 100 percent. This means that your body isn't producing vitamin D even though you may be in direct sunlight.
Vitamin D deficiency is a major global health problem. With all the medical advances of today, vitamin D deficiency is still at epidemic levels. There's over a billion people worldwide who are classed as deficient or insufficient. However , how many governments or international health organisations have you seen declaring a health emergency in order to warn the public about the urgent need of achieving sufficient vitamin D blood levels?
