Now sun is GOOD for you

The vitamin is D, nicknamed the "sunshine vitamin" because the skin makes it from ultraviolet rays. Sunscreen blocks its production, but dermatologists and health agencies have long preached that such lotions are needed to prevent skin cancer. Now some scientists are questioning that advice. The reason is that vitamin D increasingly seems important for preventing and even treating many types of cancer.

All these years we were told to hide from the sun, now it looks like they were wrong, and their error could have harmed us.

It makes one wonder, what else are they wrong about, and what damage is being done?

It happens a lot. Check out the article in the new Scientific American on the overblown obesity "epidemic." The fears generated by that socialized hysteria have caused people to practice unhealthy dieting habits and patterns.

I sometimes wonder about the safety of microwaves.

I try not to worry about most things. I figure sensationalized information is just out there to sell magazines and advertisements.

People have lived outside without sunblock for millenia. They have lived long and healthy lives.

I sometimes wonder if it is worth the potential extra two to three years on the end of my life, if I spend the next 70 doing things that I hate.

Wait a few years - smoking will be good for us too. They'll discover it helps condition the lungs to pollution.

This is not news. It has been known for decades (maybe longer) that vitamin D metabolism is dependent upon sun exposure.

It only takes a few minutes of exposure a day though to get all the rays you need, even if only your face and arms are exposed.

The news media is terrible at reporting medica break throughs, and will frequently report old facts as if they are some kind of new finding.

All you need is Vitamin D. You can get that from cereals, multivitamins, etc. You don't have to bake in the sun and get skin cancer to get vitamin D. Just don't hide in a cave.

EXACTLY!!

It amazes me that so many people take sensationalism about non-gun related things at face value without checking the source. I haven't seen any studies that said you should never go out into the sun, and the vast majority of scientific papers focus on determining facts surrounding a specific question (ie: does UV radiation cause cancer?) NOT a general topic (ie: Is sunlight good for you). A study may (correctly) conclude that there is a direct relationship between sun exposure or number of sun burns and incidence of skin cancer. Some journalist who has never taken a college level science course and has probably never heard of the scientific method reads the abstract for the paper, which they mostly don't understand because it uses scientific terminology that they (and most people) don't know, and sees the words "skin," "relationship," and "cancer." This person then writes a story about how the sun causes cancer and everyone should walk around covered in spf1000 any time a ray of sunlight may touch them.
Journalists /= scientists so don't be so quick to blame scientists for the words of journalists.

You don't need cereals, vitamins, or nutritional supplements to get all the vitamins, including D, that you need.

Eat a normal diet, meat, vegetables, grains, etc, and you will get all you need.

The average person gets plenty of sun exposure to make all the Vitamin D you need.

People have lived outside without sunblock for millenia. They have lived long and healthy lives.They died at 30. I don't consider that to be a long life. ;)

For millennia, 40 was considered old, but melanoma often doesn't appear until the 50s or 60s. Thus our ancestors simply didn't live long enough to die of skin cancer.

People also didn't brush their teeth for millennia, but most of them died by 30, so it didn't matter that their teeth were rotted out.

The problem is that we're living two-, three- or four-times longer than the natural human live span. Don't get me wrong -- I'll take every second I get -- but we shouldn't base our body-care needs on what our short-lived ancestors could get away with.

I am so old that I remember when we were all going to freeze to death in the dark because of Global Cooling.

What about those in the 1700-early 1900's? They didn't die at 30. They didn't have these benefits, either.
