With exposure to the sun, our skin naturally darkens which gives us some resistance to it's rays.
To some degree, I think we have intervened in the body's natural processes by slathering excessive potions all over it.
Is this how black people are made? (I'm sorry, every time I read this, that question pops into my head!!! :whistle
LOL
Well, tanning is temporary. When exposed to sunlight, the body releases melanin into your skin that absorbs UV radiation and darkens the skin as a protective measure. In the absence of sunlight, the process reverses.
Having stated...there is some indication that races originating in climates with more direct sun developed darker skin. Perhaps the effects of an evolutionary process (not to be confused with the 'we came from monkeys' theory) over time to adapt to the harsher sun.
But I suspect there are more factors at play too...definite differences in DNA and such.
I am not opposed to sunscreen, I use it when needed. But I have not and will not buy into what I believe is one of the largest marketing hoaxes of the century. Sunlight is free, it has no marketing department. Cosmetic manufacturers, OTOH, pour billions into advertizing their products every year. And now, the federal government has found a way to tax us on tanning through Obamacare.
I know personally 12 people that have had skin cancer. One lost half his nose, the other his life. Please explain that hoax.
The problem is taking it to extreme.
Skin cancer is real, but it's usually caused by genetics, exposure to carcinogens, or excessive exposure to the sun...including and especially sun burn.
It isn't necessary to slather one's self in sunscreen anytime they walk out the door. It isn't necessary to avoid all UV. Just keep it in moderation and don't burn.
This near-paranoia that has been created over the issue will likely increase instances of cancer by lowering people's tolerance to sun and increasing instances of burning.
Finding some reasonable ground in the middle is what would be best for us all.
