    I've always believed sun exposure is good, for MANY reasons. This is from the Journal of the National Cancer Institute.

    Journal of the National Cancer Institute, Vol. 97, No. 3, 195-199, February 2, 2005. Marianne Berwick, Bruce K. Armstrong, Leah Ben-Porat, Judith Fine, Anne Kricker, Carey Eberle, Raymond Barnhill

    Background: Melanoma incidence and survival are positively associated, both geographically and temporally. Solar elastosis, a histologic indicator of cutaneous sun damage, has also been positively associated with melanoma survival. Although these observations raise the possibility that sun exposure increases melanoma survival, they could be explained by an association between incidence and early detection of melanoma. We therefore evaluated the association between measures of skin screening and death from cutaneous melanoma.

    Methods: Case subjects (n = 528) from a population-based study of cutaneous melanoma were followed for an average of more than 5 years. Data, including measures of intermittent sun exposure, perceived awareness of the skin, skin self-screening, and physician screening, were collected during in-person interviews and review of histopathology and histologic parameters (i.e., solar elastosis, Breslow thickness, and mitoses) for all of the lesions. Competing risk models were used to compute risk of death (hazard ratios [HRs], with 95% confidence intervals [CIs]) from melanoma. All statistical tests were two-sided. Results: Sunburn, high intermittent sun exposure, skin awareness histories, and solar elastosis were statistically significantly inversely associated with death from melanoma. Melanoma thickness, mitoses, ulceration, and anatomic location on the head and neck were statistically significantly positively associated with melanoma death. In a multivariable competing risk analysis, skin awareness (with versus without, HR = 0.5, 95% CI = 0.3 to 0.9, P = .022) and solar elastosis (present versus absent, HR = 0.4, 95% CI = 0.2 to 0.8, P = .009) were strongly and independently associated with melanoma death after adjusting for Breslow thickness, mitotic index, and head and neck location, which were also independently associated with death.

    Conclusion: Sun exposure is associated with increased survival from melanoma.

    ...I agree that limited sun exposure is good for general health. I have a friend with lupus who benefits greatly from the sun (even though some lupus sufferers are cautioned to stay away from it as they are too sensitive to it). It seems to do her a world of good when she is in a lupus flare; she even tries to get herself to a warm, sunny climate like Florida or the Carribbean during these times, works like a tonic.

    Of course, those on medications that can make sun exposure more potent, or fair-skinned types need to be extra cautious. But I agree that a little bit of sun every day is beneficial for many of us.
