Turn off the lights!

Remember when your dad always pestered you about forgetting to turn the lights off after you leave a room? Looks like he wasn't just being a cheapskate and had the health of your mother in mind.

You can read a Washington Post article (and thanks to editorial cutbacks rehashed by the Seattle Times) which credulously reports a supposed link between nighttime lighting and breast cancer in women. You know it gotsta be true because the findings were published in a study by actual scientist folk working for the World Health Organization.

Apparently the study is based on an overlay of maps between regions in the world with high and low levels of nighttime light and areas with high and low cancer rates.

Of course the real reason can't be that women living in industrialized countries live longer lives and have access to medical professionals who are able to diagnose and record cancer rates. While women living in third and fourth world nations have shorter life-spans, are more likely to succumb to malaria and other pathogenic diseases before developing cancer.

So being in the sun causes cancer. And leaving the lights on at night causes cancer. Wonder when the next study will come out tying moon and starlight to cancer rates?

Time to go back to using beeswax candles, coal and whale oil lamps and gas light.

1. Oh, and just what does the presence of street lights have to do with whether the woman is sleeping in the dark? The women I know prefer a dark room for sleep, as do the men.

One would think reporters at big newspapers would know that correlation does not equal causation.

2. Well a company called C-crane sells LED lights for your home now and they use zip for power and are even a brighter light?

3. Breast cancer has been linked to stress and shift-work as well. I think this is quite plausible. My first wife died of breast cancer. Before she got sick, she was a computer systems consultant doing shift work evenings. Lots of stress. Sleep at the wrong time. Women in industrialized nations have more of certain kinds of stress and less of others. They have their kids later, and get more calories, and so have higher percent body fat. They attain puberty earlier as well. This means more exposure to hormones in their lives. Different races also have diferent rates of different cancers, even when you account for diet, culture, income, etc. All of these could be factors in cancer.

Colon cancer is linked to not enough sunshine. Skin needs sun to make vitamin D, and makes way more than you can get with supplementation. One of the worst places to live for colon cancer is Vancouver, BC. Too much sun, on the other hand, is linked to skin cancer. Chocolate, coffee and red wine are good for you at low doses, but bad for you at high doses. Even radiation in low doses can be good for you. (radiation hormesis...) Balance in most things...

But DaSarge is right @ 2, correlation is not causation, and my wife's experience is anecdotal.

Science gets better and better, (and will never be perfect) but the media is looking to sell papers, and often distorts things in order to sound sensational. The government also has an axe to grind. Corporations as well. Some research is biased. We hear too little about the studies that show no correlation.

It pays to think for yourself, and take most of what you read with a huge chunk of rock salt.

4. I have no words, but I'm sorry Bruce.
We may disagre on who to vote for, but that's where it ends when it comes to your wife.

5. speaking of lights, check out the lunar eclipse.

6. Thanks, Army Medic/Vet @ 4.

I stuck with my first wife till the end. I'm now happily remarried with a 14 month old son. There will always be a shard of pain in my heart, but having a second chance is really wonderful!

And thanks for defending my freedom, on whichever battlefield you fought.

I'll bet you and I will agree on more than we will disagree about.

Yeah, Michelle, wonderful lunar eclipse! Brick red. And the "star" to the lower left is Saturn!

7. Saturn, huh? I just looked.

8. I read studies like these and am reminded of what I once heard Dr. Dean Edell say on the matter.

"96% percent of all auto accidents were caused by drivers who had eaten carrots in the previous 24 hours. Therefore, carrots cause auto accidents."

A statement can be logical and still be false.

And yes, the eclipse was great. My wife and I made a date of getting to a higher elevation, to get away from the lights, and enjoyed the time alone together.

9. "96% percent of all auto accidents were caused by drivers who had eaten carrots in the previous 24 hours. Therefore, carrots cause auto accidents."

Exactly: Correlation does NOT equal causation.

10. The interest in cancer, melatonin and night lighting goes back to the 80's and a scientist from Richland. Here's a 2006 article on it. http://www.sciencenews.org/articles/20060107/bob9.asp
