Deficiencies of vitamin D increase the risk of skin cancer, but also the risk of other more common cancers, such as breast and prostate cancer. Dr. Brian J. Feldman of the Stanford University School of Medicine states: “Our study identifies how low levels of vitamin D circulating in the blood may have a mechanistic function in promoting the growth of breast cancer and metastasis.
Particular vitamin D …
Vitamin D or vitamin from sunlight is different from other vitamins in its assimilation and impact throughout the body. We must consider that vitamin D can be synthesized in the skin after being exposed to sunlight and is then metabolized in the liver and kidney to the metabolically active form called 1,25-dihydroxyvitamin D. Through binding to the receptor of the Vitamin D (RVD), 1,25-dihydroxyvitamin D can regulate the expression of hundreds of genes involved in skeletal functions and other biological functions. Our whole body from the brain to the bones, have vitamin D receptors.
Scientific evidence from thousands of studies indicates the benefits of exposure to ultraviolet light (not excessive) for both vitamin D production and other health benefits. You will receive the benefits of exposure to sunlight, if you avoid sunburn.
Sunscreens, more risks than benefits
The FDA admits that does not have enough scientific data to determine conclusions about the safety of 12 of the 16 active ingredients in the sunscreens on its list. To date, it is thought that at least nine of the ingredients that contain sunscreens, approved by the Food and Drug Administration (FDA) of the United States, are known to be endocrine disruptors.
The Center for Disease Control and Prevention (CDC) found that 96% of the population in the United States has traces of oxybenzone in their bodies, and this chemical is a known endocrine disruptor related to a minor sperm count in men, and the appearance of endometriosis in women.
Apart from oxybenzone – which is found in 70% of sunscreens – other commonly used chemicals, which could enter the bloodstream and cause toxic side effects – including hormonal disorders – include, among others:
1.Cinoxate 2.Dioxybenzone 3.Fenylbenzimidazole 4.Homosalate 5.Menthol antacnylate 6.Octyl methoxycinnamate (OMC) 7.Octocrylene 8.Octinoxate 9.Octisalate 10. Para-aminobenzoic acid (PABA) 11.Parabens 12.Salicylate from octilo
Studies show that: Octyl methoxycinnamate – Demonstrated to alter the release of various neurotransmitters. Octocrylene – Demonstrated to alter the expression of genes related to brain development and metabolism.
Best solution … physical photo protectors.
Photoresistors or physical sunscreens are those whose protection is due to the fact that they create a physical barrier that prevents the sun’s rays from penetrating it. The most common protective photo are: umbrellas, sunglasses, caps and hats. Among all stand out for their practicality (can be worn and worn everywhere) and effective hats and caps (with a hat or cap you protect the face, neck and face, unlike sunglasses that only protect the eyes).
Benefits of solar photoresists:
Healthier .- Unlike sunblock cream, a physical protective photo, does not come in contact with your skin, therefore does not affect your health at all.
More effective. – It is much more effective than any sunscreen, if you apply sunscreen to your skin and you expose yourself to the sun, you will also receive infrared rays in your skin (causing heat) and therefore you will continue to be exposed to burns. Example: If we put a piece of meat in the sun, and apply oil or any sunscreen the same meat will be burned, but the same piece of meat we put in the sun, but under a roof or a protective photo, the piece of meat does not it will burn.
More economical.- It is to use a physical photo-protector that constantly use sunscreens, which wear out or expire every so often, a good quality sunscreen photo can last you a lifetime.
