Sunscreen
Is it doing more harm than good?
I must admit that I have never used any sort of sunscreen on myself or my children. It seems to me to be a fad. We all have cancer cells in our bodies, but they need to become free radicals or such like to turn fully to cancer.It just seems that some people are more prone to cancer than others, inherited genes can be a factor.
I am now pleased that I have not used those products. New scientific, research has now gone a long way in proving that the producers of these products are feeding on fear and making huge profits on the way.
I quote from the book by Ian Wishart’s book “Vitamin D”.
When you apply sunscreen to your body, your children, your pregnant belly, you take a big leap of faith that you are doing the right and it is safe. Unfortunately, recent discoveries are challenging those assumptions.
Most of our sunscreens contain a range of organic chemicals to block UVB and UVA radiation. The problem with many of these organic (mostly benzene based) sunscreen compounds is that they are prone to breaking down when exposed to sunlight.
One recent scientific study reports that there is a possibility of adverse biological effects from various ingredients in sunscreen. Oxybenzone, an ingredient used in sunscreens, is purported to have a potentially disruptive effect on hormonal homeostasis.
What scientist’s have found is Oxybenzone is well and truly absorbed into the human body through the skin, after being applied in sunscreen. It has turned up in the urine and blood of 96.8% of people tested and is believed to accumulate in vital organs like kidney, liver, spleen and male testes, but also in intestines stomach heart and adrenal glands. It has also been linked to low birth weight in newborn babies.
What does it do? We know that it has an oestrogen effect and has been scientifically shown to stimulate human breast cancer cells - not necessarily a good thing ifyou are at risk of developing breast cancer. It also gives men a tweek of estrogen and displays - at a biocgemical level - what scientists call “anti androgenic” or feminising hormonal effects.
A study of 15 young males and 17 post menopausal females over two weeks measured statistically significant hormonal changes after using oxybenzone, but not enough to cause what scientists call ‘significant perturbations”. In other words, while the sunscreen chemical is affecting our bodies, this tiny study of 32 people did n’t detect anything requiring treatment or intervention. What of the effects on babies or children, however? We don’t know. We do know that sunscreen ingredients are now found in human breast milk.
A study on human wastewater outflows into rivers has found however, that all that ozybenzone we are absorbing and excreting is having a horrific effect on marine life, dramatically reducing the fertility of trout and other fish species exposed to oxybezone.
In the interest of balance, a further analysis has worked out it could take up to 277 years for a woman using sunscreen everyday ti finally get enough of a build-up of oxybenzone to harm her, pointing out that what is tixic to small animals is not necessarily so to humans.
Exposing a commercially available sunscreen product to chlorine also resulted in decreased UV absorbance , loss of UV protection and enhanced cytotoxity (meaning it becomes poisonous to human cells).
[This should give all of us something to think about. Lots of everyday products may be giving our human systems chemicals that over a period of time are doing the human race harm.]
