Okay, I distinctly said “Go, Broncos!” not “Blow, Broncos!”.

Life goes on.

Don’t you just love it when researchers and scientists (Redundant? Perhaps.) sort of lap over themselves? Take for example:

  • They’ve been telling us for years and years to avoid the sun because of the risk of skin
    cancer. They warn that if we absolutely must go outdoors, to by all means wear sunscreen.
  • Researchers are now claiming that we’re getting a dangerously low amount of sunshine-induced Vitamin D. They tell us that we absolutely must get our quota of sunshine because it stimulates the cells in our body to produce Vitamin D. They acknowledge that all of the time spent in front of computers, and all the slathering on of sunscreen is causing a deficiency of Vitamin D.
  • The National Academy of Sciences’ Institute of Medicine currently recommends that adults get 200 IUs a day of Vitamin D, which the body needs to absorb calcium. Some scientists suggest that we absolutely must get more than this….especially to prevent fractures amongst the elderly. They also point out that a deficiency of Vitamin D could even play a role in cancer, type 1 diabetes, and multiple sclerosis.
  • The suggestion of getting extra sunshine is making other researchers nervous. They keep telling us how we absolutely must avoid the sun because even a small amount increases our risk of skin cancer.
  • Okay, so there are researchers who say, “To avoid the risk of skin cancer, you absolutely must take a Vitamin D. supplement….”
  • “….of course you should know that too much is toxic, so you absolutely must be careful or you’ll poison yourself.”

Sometimes I think the people who do all of these researches are actually in the therapy business and they’re drumming up business by driving us all crazy.

  • Ah, there is one more wrinkle in the sunscreen debate (ok, I have never seen it mentioned, but it is certainly one I have thought about): many sunscreens contain titanium dioxide.

    Titanium dioxide is not toxic to humans and is very good at absorbing UV rays. However, it is also oxidative under UV light. This property is used to make things like self cleaning windows (a thin coating of titanium dioxide allows UV light to quickly breakdown organic matter on the windows), it is also added to various materials like cement and paint to produce self sterilizing and deodorizing products (there is a flourescent light that has a thin TiO2 coating – the UV in the flourescent light acts upon the TiO2 and helps eliminate odours).

    Personally, I do not want such a strong oxidative product on my skin or the skin of my kids.

    I did an experiment this summer, coating a leave with sunscreen, coating another with moisturizer and having a third control. I only did this for 1 day, I will try again this coming summer (it rained the next few days – washing out the experiment). What I observed was that the leaf with the sunscreen curled inwards to the sunscreen. The same withthe moisturizer. The control leave remained the same.

    I am not sure what caused the curling. (1) dehydration of the top surface of the leave? (2) impeded growth on the top surface, but the bottom surface grew.

    The moistirizing cream contained a bit of petroleum jelly, this may have prevented oxygen and carbon dioxide from reaching the top surface of cells in the leaf.

    The sunblock may also have contained some greasy substance.

    For this reason I need to repeat the experiment.

    My expectation is that given sufficient exposure, the sunblock covered leaf would begin to disintigrate faster than the moisturized or control leaf.

    NOTE: this is pure speculation on my part, as far as I know there is no research to support my “hmmm … I wonder?” thought.

    The conventional scientific orthodoxy is to say “if it isn’t published in a peer reviewed journal, it didn’t happen” (as an aside, environmental scientists actually buck this trend and say “if there is no research to support it or there are too many unknowns, then we must err on the side of caution” – which is in direct contrast to standard scientific orthodoxy)

  • Fascinating! I have to say, I wouldn’t want that stuff on me or my loved ones either.

    I’ve never worn sunscreen, because I’m one of those people who seek out a tan. I certainly hope and pray to never have to pay for that, but at least I get my sunshine!

    Thanks SO MUCH for the information… THe plot thickens! – Joi

  • I only wear sunscreen (avoiding any with TiO2) if I am outside for an extended period of time. I do not burn well (or maybe I should say that I burn too well and suffer horribly for it).
