Sunlight and Tanning Beds

Does Too Much Sun Cause Melanoma?
Group: Effectiveness of Sunscreens Hazy “In their newly published analysis of more than 900 brand-named sunscreens, EWG researchers concluded that 7% of the products with SPF ratings of 30 or higher did not protect against UVA rays. Only 15% of the sunscreens met the group's criteria for safety and effectiveness by providing broad-spectrum sun protection (denoting protection against both UVA and UVB radiation), remaining stable in sunlight, and containing only active ingredients considered safe by the EWG. The top-selling sunscreen brands tended to be the poorest performers, with none of market leader Coppertone's sunscreen products consider to be both safe and effective by the EWG.”
Healthy Tanning Beds? Experts Say No
Heat Is On To Protect Child Sunbed Users, UK “The consumer organisation found that around 3 per cent of under-16s have used a sunbed. Accepted health advice in the UK is that under-16s and fair-skinned adults with 'type one' skin that burns easily should never use a sunbed.** Although the industry trade body, The Sunbed Association (TSA), instructs members to ban under-16s and to advise people with type one skin to avoid sunbeds, its membership covers only a quarter of the UK's 6,000 salons, and other salons are not regulated at all.”
Lack of Sunshine Vitamin May Cloud Survival Odds“It has been estimated that at least 50 percent of older adults worldwide have low vitamin D levels, and the problem is also thought to affect substantial numbers of younger people. Possible reasons include decreased outdoor activities, air pollution and, as people age, a decline in the skin's ability to produce vitamin D from ultraviolet rays, the study authors said.”
Older Australians At Risk Of Sun-related Skin Cancer Death
Some sun may guard against non-Hodgkin's lymphoma “Recreational sun exposure could help prevent a type of blood cancer involving the lymph nodes called non-Hodgkin's lymphoma (NHL), according to pooled data from 10 studies. … Sunlight exposure causes the skin to produce vitamin D, which might help explain how sunlight could be protective against NHL, Kricker and colleagues suggest. However, other factors could account for the relationship, they note, such as exercise, given that people with more recreational sun exposure would likely be more physically active.“
Sunbed use 'puts lives at risk' “Research suggests people who start using sunbeds under the age of 35 increase their risk of malignant melanoma by 75%. … the intensity of some UV rays from sunbeds can be as much as 15 times higher than that of the midday sun. Repeated exposure to UV damages the DNA in skin cells, which increases the risk of skin cancer and makes skin age faster. … "You can't always see the damage that UV does straight away. It builds up over time. But every time you use a sunbed you are harming your skin and increasing your risk of skin cancer." “
Sunburn Alert: UVB Does More Damage To DNA Than UVA “According to researchers from City of Hope National Medical Center in Duarte, California, UVB light is more harmful to our skin because our bodies are less able to repair the DNA damage it causes than the damage caused by UVA light. To reach their conclusions, scientists exposed three sets of cells to UVA light, UVB light and simulated sunlight. Then they compared these cells to an unexposed control group to analyze how well these cells were able to repair the damage. In addition, they analyzed published data on the genetics involved in human skin cancers. The researchers found that cells were more easily able to repair the damage caused by the UVA light, which explains why UVA light has been perceived as "safer" than UVB light. Despite this perception, scientists and public health experts caution that UVA light can and does cause serious damage that can and does lead to skin cancer. "We know that sunlight causes skin cancer and that breakdown of the ozone layer exposes us to ever more ultraviolet radiation. This work tells us that both forms of UVA and UVB in sunlight cause damage to DNA.”

JOURNAL ARTICLES:
Addressing the health benefits and risks, involving vitamin D or skin cancer, of increased sun exposure. (Proc Natl Acad Sci U S A. 2008) “These data, together with those for internal cancers and the beneficial effects of an optimal vitamin D status, indicate that increased sun exposure may lead to improved cancer prognosis and, possibly, give more positive than adverse health effects.”
Estimating the global disease burden due to ultraviolet radiation exposure. (Int J Epidemiol. 2008) “CONCLUSIONS: Sun protection messages are important to prevent diseases of UVR exposure. However, without high dietary (or supplemental) intake of vitamin D, some sun exposure is essential to avoid diseases of vitamin D insufficiency.”
Exposure to sunlamps, tanning beds, and melanoma risk. (Cancer Causes Control. 2008)
Overseas Sun Exposure, Nevus Counts, and Premature Skin Aging in Young English Women: A Population-Based Survey. (J Invest Dermatol. 2008)
Sunlight exposure, antioxidants, and age-related macular degeneration. (Arch Ophthalmol. 2008)
Sunlight, UV-radiation, vitamin D and skin cancer: how much sunlight do we need? (Adv Exp Med Biol. 2008) “Vtamin D is the sunshine vitamin for good reason. During exposure to sunlight, the utraviolet B photons enter the skin and photolyze 7-dehydrocholesterol to previtamin D3 which in turn is isomerized by the body's temperature to vitamin D3. Most humans have depended on sun for their vitamin D requirement. Skin pigment, sunscreen use, aging, time of day, season and latitude dramatically affect previtamin D3 synthesis.”
Tanning and Cutaneous Malignancy. (Dermatol Surg. 2008) “CONCLUSIONS Skin cancer poses a major public health concern and tanning remains the most modifiable risk factor in its etiology. Social, economic, and legislative issues have become tightly intertwined with the complex nature of human behavior in the continued pursuit of an activity that clearly has detrimental effects on one's health.”
UV Radiation: Balancing Risks and Benefits. (Photochem Photobiol. 2008) “In the summer at noon, there should at mid-latitudes be sufficient UV to photosynthesize optimal vitamin D in approximately 1 min for full body exposure, whereas skin damage occurs after approximately 15 min. Further, while it should be possible to photosynthesize vitamin D in the winter at mid-latitudes, the amount of skin that must be exposed is larger than from the hands and face alone. This raises the question of whether the action spectrum for vitamin D production is correct, since studies have reported that production of vitamin D is not possible in the winter at mid-latitudes.”
Vitamin D and Sunlight: Strategies for Cancer Prevention and Other Health Benefits. (Clin J Am Soc Nephrol. 2008) “Recent studies suggested that women who are vitamin D deficient have a 253% increased risk for developing colorectal cancer, and women who ingested 1500 mg/d calcium and 1100 IU/d vitamin D3 for 4 yr reduced risk for developing cancer by >60%.”
