So much of skin damage and premature aging, such as wrinkling and freckling of the skin, is due to over-exposure to the sun’s harsh UV rays.
Having said that though… did you realise that our bodies require sunlight to synthesise Vitamin D?
And did you know that 75% of the body’s Vitamin D supply is generated by exposure of our skin to the sun?
So getting enough sunlight, but not too much is extremely important!
OK, so why the fuss about over-exposure to the sun?
After all, doesn’t a lovely sunny day make us happy? And with bonus Vitamin D, what IS the fuss about?
As Summer is fast approaching us here in Australia, I can’t help but think we all need a reminder that although sunlight is important in the quest for Vitamin D, AND we love the sun, we need to consider the devastating effects of too much UV.
Over-exposure to UV causes radiation damage which weakens the skin and in turn ages it. UV rays are at their most dangerous as we spend leisurely time outdoors during the summer months. However, too much of the thing that brings us “the letter D” is damaging all year round. Regular periods of over-exposure to the sun will end up breaking down skin fibres of collagen and elastin… the result is the epidermis (the outermost layer of skin) starts to thicken and sunspots, dilated capillaries and hard leathery skin appear.
Diet can also effect how your skin deals with the sun. I read an interesting piece in a ground-breaking book called “The Fat Revolution” – written by Christine Cronau – where she talks about the benefits of natural fats in the body and the relationship with skin and how the two interact with the sun. Christine’s book is definitely worth a read, as it makes you sit up, take notice and question the hype we have been fed over the years.
