Blue Light Like That From Smartphones Linked To Some Cancers, Study Finds (cnn.com)
A new study, published Monday in the journal Environmental Health Perspectives, found that exposure to the kind of blue light emitted by outdoor LEDs, smartphones and tablets may increase your risk of breast or prostate cancer. The study compared previous exposure to artificial lights at night between approximately 2,000 breast or prostate cancer patients and approximately 2,000 controls living in Barcelona and Madrid. Slashdot reader al0ha writes: This study seems to say that exposure to LED light temperatures higher than 3,000 Kelvin suppresses melatonin because it contains increased blue light, and at least one city (Davis, California) has gone to the expense of removing higher temperature LED lights and replacing them with ones that have lower color temperatures. Specifically, the study found that "those exposed to high levels of outdoor blue light at night had around a 1.5-fold higher risk of developing breast cancer and a twofold higher risk of developing prostate cancer, compared with those who were less exposed," reports CNN. "Men exposed to high levels of indoor artificial light also had 2.8-fold higher risk of developing prostate cancer, according to the study."
Damn! Gonna go republican then, because only then can I shove things up everyone's and get away with it.
They're the cause of everything bad that happens to conservative snowflakes. *(Anecdotally.)
I have absolutely zero proof one way or the other, but this has “complete bullshit” written all over it.
"men who slept in “quite illuminated” bedrooms had a higher risk of prostate cancer (OR=2.79; 95% CI: 1.55, 5.04), whereas women had a slightly lower risk of breast cancer (OR=0.77; 95% CI: 0.39, 1.51)."
It's not uncommon for a single study to show a statistically significant, or even dramatic, effect on cancer rates. Check out this graph for good examples. You can't say anything about these kinds of studies except, "was within the margin of error."
"First they came for the slanderers and i said nothing."
Get outside and talk to people?
Non ionizing radiation does not cause cancer.
They have the proposed mechanism: blue light causes your body to produce less melanin, which means less protection against natural sunlight. It is a hypothesis worth testing, anyway.
Researchers that published this bull shit should be imprisioned.
That's a little extreme.
"First they came for the slanderers and i said nothing."
And notices entrainment of brain waves.
You failed at science. Melatonin is not what darkens your skin. Learn how to science.
incel is about taking matters into your own hands.
They have the proposed mechanism: blue light causes your body to produce less melanin, which means less protection against natural sunlight. It is a hypothesis worth testing, anyway.
The story is about melatonin, the sleep-related hormone, not about melanin, the skin pigment.
Hence this is not about sunlight protection, but about weak sleep quality, which is already known to be statically linked to cancer
Not exactly sleep. Melatonin also regulates reproductive-related hormones that would support an effect on prostate and breast tissues.
I don't know about cancer, but just for the sake of your eyes, get F.lux!
It automatically dials down the blue component of your screen at night (with a gradual transition). At the very beginning, it takes a minute or so to get used to, and might look weird.
BUT! After using it for a couple of hours at night, I dare you to vidit a webpage with a white background, and turn it off for a second. Your eyes will hurt, and you will notice that looking at a monitor is like staring into a lightbulb at night. It's really painful.
Please, just get F.lux!
Science is hard!
"Researchers that published this bull shit should be imprisioned." If Italy can send scientists to prison for NOT predicting an earthquake... why not?
It's not that blue light that damages breast or prostate tissue directly. It's neurologically-mediated endocrine changes that have been well documented now for decades. It's only more recently that those endocrine changes have been linked to cancer.
The chain of causation is blue light -> retina -> optic nerve -> suprachiasmatic nucleus of the hypothalamus -> pineal gland -> {disrupted hormones including melatonin and serotonin} -> {multiple and widespread physiological disturbances including disturbed sleep and chronic inflammation} -> {breast and prostate cell damage, precise mechanisms unknown}.

One of them got a job.
For the last two years I suffered the new violent outdoors lights, most of them high temperature color.
They make life miserable, for multiple reasons, under the pretense of "safety" and to help the surveillance cameras.
It killed off most of the nightly social life in my town ; it messes with the eyes and brain. (btw same is happening on the laptop with TN monitor I'm using. I think I need to buy some higher end LCD, or find a CRT again as CRTs trivially display a uniform black not blacklight bleed)
You might not be aware that having a more miserable life makes you weaker and die more easily or faster.
In the winters, violent outdoor lighting has been particularly bad. I get out and there's that permanent daylight-like artificial light. I have no sleeping schedule and some places are lit like a german stalag when a prisoner is escaping and they're looking for them with search lights.
Haven't used sunglasses yet, because I have prescription glasses. I can't use $5 sunglasses.
I'm glad studies come out, hoping for more - my town is planning to convert more and more remaining yellow lights to white lights, while in their communication they say it's such a great thing because the new lights have better lumen per watt.
That Italian thing was too extreme, too.
Well, that is one factor.
But actually the chain of bullshit is MUCH longer here.
Basically, it is know that too much 'blue end' spectrum light can mess with your melatonin levels, as well as other sleep triggers (including psychological..)
So then you end up with less sleep, more stress, opprer general body health.
And then you see a rise in some cancer rates.
And its all the fault of Blue light! From Smartphones! no, really!
Its the blue light, not the stressing about peoples thoughts on your current instabookshite, not the being interrupted at 11pm with a work message, not
stressing about your mortgage, not worrying if you can survive in the 'gig' economy.
No, its because the smartphone screen is a little the wrong colour.
They obviously need more funding. I bet they could link it to heart disease, suicide rates, hair loss, divorce rates, and child abuse if they tried a little harder!
Perhaps just go with 'Thing everyone is doing right now linked to all bad things in their lives', that way they dont need to rewrite it every few years.
The story is about melatonin, the sleep-related hormone, not about melanin, the skin pigment.
That makes more sense. I mean, the summary mentioned prostate and breast cancer and I was wondering... what the HECK are people doing with their phones where melanin level would affect prostate cancer?

If you're looking at a white screen background after 10 PM, yes it's going to be difficult to sleep and your biological clock is probably getting messed up in ways that may harm your health.
Certainly going to white on black, and dim, when you're reading to go to sleep helps. But not driving yourself so hard and having a life helps more.
Think about not spending your entire life doing what others expect of you.

I hate white LEDs. They are now everywhere and they suck.
Tried a few LED computer monitors and had to pawn them off on others because I couldn't stand using them. It's impossible to turn down the backlight because they are using PWMs and no matter what you do it is impossible to correct out the blue tinge from the crappy output spectrum especially at lower brightness levels.
Finally found an oldschool but higher end CFL display on sale with LUTs and color calibrator. Had to eat into contrast a bit to get the brightness I wanted but at least white actually looks white not some sick blue and the display doesn't give me a headache at night.
City replaced all of our nice HPS street lighting with blue tinge LEDs made by the lowest bidder. Driving at night is now unpleasant, blinding and obnoxious. They don't even bother with diffusers because saving a few pennies is all that matters.
Around here anything with blue leds in them gets taped or painted over or thrown in the trash. Of all color LEDs one could chose... to pick the most annoying needlessly over bright color possible really sucks. I think vendors have received the message on the use of blue LEDs but they need to be constantly reminded.
Christmas lights break my heart. I used to love looking at nice colorful bright Christmas lights. Now it is these eerie half wave blue flickering things that make everything seem dead. What's the point of decorating if the decorations end up being gross and unappealing?
I am not against LEDs. Just technology that sucks. Myself I have some LEDs but they use remote phosphors and high CRI with lower K. They look fine and don't have insane blue spikes in output spectrum. If I had the money I would probably have sprung for a GB-R or whatever LED display with a wide gaumet.
Most of the problems with blue light are caused by bean counters who don't give a fuck about anything other than BOM cost. Things don't have to suck but it involves customers pushing back so it is clear what we want and what we are not willing to pay for.
The possible health, eye, cancer links and negative affects on non-humans to blue lights have been in the news for many years now. It's probably prudent to hedge against it especially because it's a good excuse to get rid of or stop the spread of annoying shit quality lighting.
Melatonin is not likely to have any impact one way or another on breast or prostate cancer. This is not a proposed mechanism. It's fantasy. Now, if they had shown a link between these lights and skin cancer, that actually might make sense. But as it stands it's overwhelmingly likely that the correlation is due to some other environmental factor.
Also, the idea that smart phones or tablets might have any contribution to this is utterly absurd. Bright street lights are barely within the realm of plausibility in terms of having an impact on melanin production. Electronic devices are nowhere near there.
That said, lower color temperature lights at night are far more pleasant, and don't muck up night vision quite as much. So it would be nice to see lower color temperatures used more often. But not because of cancer fears.
Typo in the above: I meant melanin, not melatonin.
"Men exposed to high levels of indoor artificial light also had 2.8-fold higher risk of developing prostate cancer, according to the study."
Uh... So why are so many men exposing their prostates to their cellphone lights at night?
Bah. And I misread the whole thing. This comment is worthless. Please disregard.
Is the study qualitative or quantitative. Is it double blind?
Too many studies that are data driven with no explanation of the underlying causes or are pure speculation.
This one sounds fishy to me.
You're holding it wrong.
The story is about melatonin, the sleep-related hormone, not about melanin, the skin pigment.
Hence this is not about sunlight protection, but about weak sleep quality, which is already known to be statically linked to cancer
Shit... I didn't know that.
What do you expect, these are the same "scientists" who hype up bullshit like global warming and evolution. Science is now all about liberal leftist marxist commie politics and if you disagree you are silenced.
You're still not funny.
Love,
liberals, conservatives, and people who like comedy.
I live out on a county highway. There is some light pollution from a neighbor who has a floodlight by his garage, but there is mostly pure dark when I step outside at night. And coyotes howling in the distance sometimes. And occasionally the local owl hoots.
What the fuck are you doing that causes sunlight to reach your prostate? Are you the goatse guy?
You are lucky, I get coyotes howling 1m under my window.
It is likely to be bullshit, but for a different reason:
It's a correlation study. Correlation studies are inherently weak, for the reason that it's all too easy for there to be a confounding factor which produces the observed effect.
If I were to guess, if there is a real correlation, it stems from lack of sleep. Not getting enough sleep over an extended period of time contributes to a tremendous variety of health problems. And exposure to blue light seems to impact sleep patterns. So basically: get good sleep, and you should be fine.
Wow! Good chart. I simplified the link: Everything we eat both causes and prevents cancer.

light temperatures higher than 3,000 Kelvin
Like, say, daylight? I guess a person must always sit in the dark to avoid cancer...
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
Simple hypothesis far more likely than god damned melanin (what idiot thought of that?). Blue light causes you to get worse sleep. Plenty of studies on it, already confirmed. You get worse sleep, your body doesn't repair itself as well, including looking for errors during mitosis, your immune system doesn't hunt cancer as well, you're more likely to get cancer. Boom, easy.
Just tell people to stop holding their phone near their prostate
So it's bullshit.
It's very weak and probably something else.
But you completely agree with it!
Eliminate water. Some people drown!
Yes, bright daylight messes with your sleep hormones, which is why most people... sleep at night...
Project much?
weak sleep quality, which is already known to be statically linked to cancer
What? Well...fuck. guess I know how I'm dying.
Cell phones cause cancer. THIS NEW SCIENCE PROVES IT!!!
Actually this has been known for years, the study has nothing to do with phones, and it's all light not just blue light. Blue light is 'stronger' than other wavelengths, but all light matters. Even hallway light coming into your room from around the cracks in your door have a detectable effect on your quality of sleep.
>Non ionizing radiation does not cause cancer.
Thermal radiation, which is non-ionizing does cause cancer. This is proven in studies of people who drink excessively hot fluids. Your statement is easily disproven.
Itâ(TM)s not the radiation, but tissue reaching above certain temperature. Doesnâ(TM)t matter if caused by IR, mechanical stress or contact with something hot.

Urg. No. No, no no.
Melatonin is a known highly effective anti-oxidant. It has long been supposed that melatonin deficiency was the cause for the link between poor sleep and cancer.
Melatonin is also known not to be produced when your eyes are exposed to blue light. Ergo, one may suppose that exposure to blue light in the evening when you may be sleeping can increase your chances of getting cancer over your lifetime. This study shows that the supposition is likely correct. This all makes sense, none of it is weird. The idea that smart phones or tablets have a contribution is not weird in the slightest, because the LED backlights in them have a very high color temperature, usually.
It's not bullshit. This has long been suspected for a long time.
Melatonin is an active cancer fighter in your body.
Blue light completely eliminates the production of melatonin during the evening hours.
A lifetime of having deficient melatonin should cause higher incidence of cancer.
Staying away is likely linked due to the fact that, at least in this day and age, most people staying up late are exposing themselves to some kind of intense blue light.
Blue lights, hot drinks, barbecued meat, sunshine... fucking everything will supposedly give you cancer now, huh? It's enough to make me give up on avoiding carcinogens and just accept cancer as an inevitability. They really oughta slow down these reports or at least stick to ones that are a bit more conclusive. They're having the opposite effect on me. They're making me NOT CARE.
Was this anti-LED lamp study funded by "Big Sodium" so that municipalities would go back to purchasing the orange sodium-vapor lamps? Follow the money, Sheeple!!!! (sorry, I just HAD to add that, he he)
Articles like this give me the impression that the field of study is still very uncertain: Circadian disruption and breast cancer: from melatonin to clock genes. (March, 2005)
Quote: "The global impact of breast cancer is large and growing. It seems clear that something about modern life is the culprit, yet there is thus far a lack of satisfactory explanations for most of the increases in risk as societies industrialize."
I've been experimenting with Melatonin: Schiff Melatonin Ultra 3 mg. 365 Tablets. ($11.94, but now, no one has stock, apparently. I have no idea why.)
Melatonin tablets seem to encourage sleep.
Over many years of having a business, I've developed a preference for working for an hour or 2 early in the morning, maybe 3 am, and later taking a nap in the morning or afternoon. I'm healthy. Do I have a different circadian rhythm?
I've noticed that people often act sure when their thinking is actually extremely sloppy. As quoted above, "... there is thus far a lack of satisfactory explanations..."
He has to put in a few sciency things he thinks might be relevant to counteract all his anti-science posts.

Funny your comment reminds me of someone else who recognized that "Relativity is a Jewish hoax" and was a strong proponent of correct Aryan physics, which as a matter of history was nothing more than racist and incorrect bullshit. You are wrong in exactly this way too you republican dip shit!

Correlations do not prove causation, however they do imply it. This is something a lot of armchair "scientists" miss when trying to make arguments against research that they don't like. The way you get around this is you look at where the correlation and observed criteria provide clear predictive value for blindly inferring the presence of the correlated entity. If you can predict the presence of the correlated thing 10,000 times out of 10,000 akin to correctly guessing 10,000 coin flips correctly without error, then you have a pretty good argument that this case of correlation does show a causal factor. may things do play into this and some of them are so facepalm obvious that they are not usually mentioned, like if one thing correlates and causes another, if it is the cause it would have to precede by some positive amount of time the thing it is correlated with, otherwise those two correlated things likely have a common cause, which is one of any number of confounders. This is simply cause for pointing out that there is a common sense and logical way around the whole correlation is not causation argument, and it is not as big of a dead end to research as most would be scientist wanna be joe six-packs would have you believe over a beer during a halftime argument.
So is reading, apparently.
Go to youtube and good the nature of things lights out.
The nature of things is a Canadian series and they had an episode that delved into this a few years ago.
Correlative study.....Guess what people who spend a lot of time out at night do? Drink, Smoke, do drugs.....lose sleep......Wow.,.....hmmmm....I wonder if it could be any of those things rather than fucking blue light that we get all fucking day long.
The science doesnt agree with you. Go to youtube and watch the nature of things lights out, to see an investigation into this. And you it is about melatonin.
Prostates don't get sunlight....and breast cancer too....If they said they saw an increase in say....skin cancer....then maybe their imagination would be closer to reality.
You know what else produces less melanin? Lack of sleep!!!!!
yeah go figure!
Um. At that temp, wouldn't burning to death be more hazardous than the cancer?
Like the subjects says. "Horse shit"
I read at +2. If your post doesn't reach that level I will not see or respond to it.

Can't wait to see the Daily Mails headline tomorrow.
Has this paper been peer reviewed?
Has the paper spoken of all the people removed from the study for not showing results they were after?
Has the paper shown results from a broad range of people, including risk levels and environments? No good excluding people of low risk, because they are low risk.
Was the study impartial? Who funded the study and were they seeking a result before they started?
Are they have a control group of comparatively equal health and risk?
Can they show the study to be replicable?
Move along, nothing to see here

This is why you shouldn't believe that exciting new medical study. (Vox.com, Feb 27, 2017)
I suspect it was paid for by a company in California that only produces LED lights that exclude blue wavelengths. Or, blue is the first color California is attacking so that people with color blindness don't feel left out or embarrassed. Green is next!
