    Abstract


    Background
    Sunlight exposure and fair skin are major determinants of human vitamin D production, but they are also risk factors for cutaneous malignant melanoma (MM). There is epidemiological evidence that all-cause mortality is related to low vitamin D levels.

    Methods
    We assessed the avoidance of sun exposure as a risk factor for all-cause mortality for 29,518 Swedish women in a prospective 20-year follow-up of the Melanoma in Southern Sweden (MISS) cohort. Women were recruited from 1990 to 1992 and were aged 25 to 64 years at the start of the study. We obtained detailed information at baseline on their sun exposure habits and potential confounders. Multivariable flexible parametric survival analysis was applied to the data.

    One more brick in the wall. Some day we collectively will discover that we are meant to be Earthlings living on a planet which essentially is dependent upon living with our nearby star, the Sun.

    It depends where you live. There is a happy medium somewhere between sun avoidance and over exposure. If you work outside in Oz, you had better protect yourself in some way. The mid-day sun is unbearably hot, and you will quickly burn if you stay over the recommended 15-20 minutes. I have had sunburn on the neck and face even in winter, when a breeze was blowing so I didn't feel hot. This is quite common.

    ' Australia and New Zealand have the highest incidence and mortality rates of melanoma in the world, according to Australia's Department of Health and Aging. In those two countries, the risk of developing melanoma before the age of 75 is 1 in 24 for males and 1 in 34 for females.'

    Whole Lee. Schitt.
    Is that because you are closer to the open ozone hole? Or have Australia and NZ been that extreme even before the ozone layer thinned?

    'Melanoma -- the most virulent form of skin cancer -- is caused by harmful ultraviolet light from the sun.


    Australia's proximity to Antarctica, where there is a hole in the ozone layer that filters out UV rays, also increases the risk.


    However, higher rates of detection and tracking also explain the number of cases of cancer diagnosed each year, according to lead researcher Christine Sturrock from the Australian Institute of Health and Welfare.'
