Sunscreens come with SPF indications that we often consider the ultimate protection against sunlight and eventually skin cancer. However, things are more complicated than this. What is, really, the meaning of SPF on sunscreen labels? Do we get the sun protection that we think we do?
If you have ever wondered how much protection you get from the sun when inside your car, you need to take a look at photos recently published in the New England Journal of Medicine of a 69-year-old truck driver who shows clear evidence that 25 years of driving can lead to damaged skin, simply from the sun’s rays. But is it wrinkles that you should be worried about or is skin cancer from driving the real concern?
For the last 30 years, we have all had the message drummed into us regarding the dangers of sun exposure and the increased risk of skin cancer. But in recent years it has become clear that some of us are not getting enough of vital vitamin D – something that we all need for our health and yet can only come from the sun. How on earth do we balance this need for the sun with the dangers it can pose and is there a link between vitamin D and skin cancer?
