Optimize your sun exposure without sunscreen
by Dr. David Jockers
(NaturalNews) Before you lather up with sunscreen for a long day outside you should look at what is actually in the bottle. These lotions contain chemical mixtures that have been proven to block UVA & UVB radiation exposure and prevent sunburn. These chemical cocktails are now linked to serious health consequences including an increased risk of cancer. Natural strategies allow us to optimize sun exposure without chemical toxins and to boost our health.
The sun provides our body with an essential stress through its UV radiation. This UV radiation stress signals a molecule on the skin (7-dehydrocholesterol) to convert to the active form of Vitamin D3 (cholecalciferol) in the body. Vitamin D3 synthesis depends upon UVB radiation, which effectively penetrates only the epidermal (outer) layers of the skin.
Vitamin D deficiency is a current epidemic in our society today affecting 90% of our world`s population. According to Vitamin D expert Michael Holick, `We estimate that vitamin D deficiency is the most common medical condition in the world.` It is clear that most people are not getting enough healthy sun exposure. Vitamin D deficiency is linked to increased risk of virtually every form of cancer including skin cancer, cardiovascular disease and immune insufficiencies.
Melanoma is a deadly form of skin cancer that has always been associated with excessive sun exposure. However, many recent studies have shown that individuals wearing sunscreen had a higher likelihood of getting melanoma. Additionally, melanoma patients with increased levels of sun exposure were less likely to die than other melanoma patients. Patients, who already had melanoma and a lot of sun exposure, were prone to a less aggressive tumor type.
Due to worries over excessive sun exposure many people choose to lather up with sunscreen. In 2007 the FDA admitted that they "are not aware of data demonstrating that sunscreen use alone helps prevent skin cancer." The International Agency for Research on Cancer recommends clothing, hats and shade as primary barriers to UV radiation. They have written that "sunscreens should not be the first choice for skin cancer prevention and should not be used as the sole agent for protection against the sun."
Up to 30% of the sunscreens on the market contain a form of Vitamin A that may speed the development of skin tumors and lesions. The industry uses retinyl palmitate in its formulas because it is an anti-oxidant that enhances skin health. Numerous studies have shown that Vitamin A can cause excessive skin growth (hyperplasia) and that sunlight can damage the anti-oxidant and cause it to form harsh free radicals that damage DNA.
Other toxins found in common sunscreens include:
Benzophenones (dixoybenzone, oxybenzone) Cinnamates
PABA esters Salicylates Digalloyl trioleate
Menthyl anthranilate Avobenzone
All of these ingredients are highly toxic to our skin and bodies. They produce rampant amounts of free radicals that create an excess of oxidative stress. Oxidative stress is a potent carcinogen that causes genetic mutations. These chemicals are highly estrogenic in that they mimic the effects of estrogen within our body and cause hormonal disruptions that increase cancer cell formation.
Natural sun screen protection comes from tropical oils such as coconut, eucalyptus, jojoba, & shea butter. Zinc oxide and titanium dioxide when applied appropriately are powerful protectants from the damaging effects of too much sun. It is always advisable to wear hats and other clothing if you know you are going to spend an excessive time in the sun. Apply aloe vera and/or coconut oil on any area that is overexposed to help ease the pain and nourish the skin. Both of these sources support the skin microflora and harmonize the healing process.
