Chemicals From Sunscreen Leach Into Our Blood
https://www.iflscience.com/health-and-me...our-blood/

INTRO: A new study by the US Food and Drug Administration (FDA) suggests that chemicals in sunscreen leach into our blood at potentially unsafe levels. However, both the FDA and scientists are quick to warn that you shouldn’t throw out your sunscreen and face the Sun unprotected just yet.

Looking at spray, lotion, and cream sunscreens, researchers found that four chemicals – avobenzone, oxybenzone, octocrylene, and ecamsule – were present in the blood at surprisingly high levels after use. Levels, in fact, much higher than the FDA’s threshold for topical medications that must undergo safety tests. "It's not like they went a little bit over," Dr Kanade Shinkai, a University of California, San Francisco dermatologist, said in a statement. "It's really quite high, orders of magnitude higher than that."

While the results seem a bit alarming, the study only involved 24 people in a lab-based setting. Therefore, absorption of these chemicals might be different in real-life settings [...] Additionally, the sunscreens were tested “under maximal use conditions”, meaning they were applied four times a day for four days across three-quarters of each person’s body. [...] More research is needed to back up the findings and work out exactly what the health impacts of these chemicals are. Still, the danger posed by exposure to the Sun’s harmful UV rays likely far outweighs the potential risk that chemical sunscreens might pose... (MORE)



Well Water's Spillover Effect: Heart Damage?: Does your home draw its water source from a well? A new study finds that well water may be injurious to heart health in young adults -- if it contains arsenic. [...] researchers looked at more than 1,300 Native American adults, average age about 31, in Oklahoma, Arizona, and North and South Dakota. Their urine was tested for arsenic and their hearts assessed using ultrasound. (MORE)

Study: Arsenic In Drinking Water Of Several States, Including Florida, Damages Hearts Of Young Adults: . . . young adults developed heart damage after only five years of exposure to low-to-moderate levels of arsenic commonly found in groundwater. [...] Long-term exposure to inorganic arsenic, a human poison that occurs naturally in the earth’s crust, has been linked to various cancers, kidney damage, hypertension, cardiovascular disease and diabetes. Organic arsenic, such as what’s found in seafood, is not known to be toxic to humans.

States that may have high-levels of arsenic in groundwater include Washington, Oregon, Nevada, California, Arizona, New Mexico, Maine, Massachusetts, New Hampshire, New Jersey, Maryland, Michigan, Wisconsin, Illinois Ohio, Indiana, Florida, Virginia, North Carolina, South Carolina.

While arsenic can be found in the air and soil, the World Health Organization says the greatest threat to public health globally comes from groundwater, which is contaminated as it flows through rocks and minerals containing arsenic. (MORE)

Therefore, absorption of these chemicals might be different in real-life settings where people are, for example, swimming in the sea or working outside. Additionally, the sunscreens were tested “under maximal use conditions”, meaning they were applied four times a day for four days across three-quarters of each person’s body. Even with best intentions, many of us probably don’t apply sunscreen quite so rigorously, even though it’s recommended to maximize protection from the Sun.

I don't use sunscreen or drink well water. I monitor my time in the sun and if anything I'm looking at a farmer's tan by summer's end. At our summer cabin I bring my own drinking water despite the presence of a nearby well and treatment equipment. 

The people I see smeared with sunscreen are usually the youngsters, especially babies. After reading about sunscreen lotion's bad chemicals it might be time to become somewhat Jenny McCarthyish and think about autism or any other maladies that are prevalent these days. Not that I know sunscreen is a factor, but news like this is apt to bring on some celebrity's take. Odd to think parents avoid having their kids vaccinated yet splatter toxins all over their child's skin..
