Being sun smart does not necessarily mean only avoiding the sun or lathering a thick layer of sunscreen.
A recent 2014 research article published in the Journal of Internal Medicine found that “The mortality rate amongst avoiders of sun exposure was approximately twofold higher compared with the highest sun exposure group, resulting in excess mortality with a population attributable risk of 3%.” The major study conducted by researchers at the Karolinska Institute in Sweden followed almost 30,000 women for over 20 years. (See attached Article 1 below)
A research study published in 2000, in the International Journal of Cancer, demonstrated research results that “substantiate the hypothesis that sunscreen use, by permitting more time sunbathing, is associated with melanoma occurrence.” (Article 2)
Vitamin D is needed “to maintain good health and to keep bones and muscles strong and healthy.” (http://www.cancer.org.au/preven…/sun-protection/vitamin-d/).
Sunscreens with an SPF of 50 block 98% of UV rays (http://www.sunsmart.com.au/uv-sun…/slop-on-sunscreen), therefore eliminating our ability to create Vitamin D. (Sunscreens greater than SPF50 may block more?) It is commonly known that “The best source of vitamin D is UV-B radiation from the sun.” (http://www.cancer.org.au/preven…/sun-protection/vitamin-d/ ) As the Australian National Health and Medical Research Council state on their website “it is almost impossible to obtain sufficient vitamin D from the diet alone. (http://www.nrv.gov.au/nutrients/vitamin-d).
The Medical Journal of Australia published a research article in 2002 concluding that “The prevalence of vitamin D deficiency in Australia appears to be much higher than was previously thought.” (Article 3)
So if we block our major source of Vitamin D by 98%, could that potentially lead to many other health concerns?
We had shared a link on our facebook page (www.facebook.com/ChiroWorksSG) which suggested that we should all nourish ourselves (more) with vitamin D. We are aware that skin cancer can occur by overexposure to ultraviolet (UV) radiation from the sun. (http://www.cancer.org.au/about-cancer/types-of-cancer/skin-cancer.html). However prolonged exposure to the sun, including using synthetic sunscreens (which can create a false sense of security by disabling the skin’ early detection system – the sunburn) results in overexposure to UV radiation, hence damaged cells and a possible outcome of cancer.
So we would still suggest we all get out there and soak up the sunshine.
Just be smart about the amount of time you spend in the sun.
