    Following a study examining the exposure to artificial lights at night between cancer patients and controls living in Barcelona and Madrid, researchers say that blue light, which is often emitted by outdoor LEDs, smartphones, and tablets, can increase the risk of breast or prostate cancer. One theory is that blue light reduces melatonin, which acts as an antioxidant.

    Exposure to blue light is known to decrease the release of melatonin in the brain, which helps regulate the body's circadian rhythm, according to Knutson. Melatonin is also known to act as an antioxidant, and adequate levels may be necessary to suppress the growth of certain hormone-sensitive cancers such as breast and prostate cancer, according to Sánchez de Miguel.

    Well, if the robots don't kill us all, the LED lights will. Just look at the light pollution imagery taken from satellites.

    Everything is killing us, that's why we live to 80+ now instead of 40+ :p

  6. Well, I actually like blue status lights. Of course they can be way too bright. That's where electrical tape comes in handy. And "f.lux" just doesn't really work for me.

    In English "we're screwed" again. Life is hazardous to your health.

    I never liked the damn things at night. Red doesn't destroy your night vision like blue does. I usually end up taping over them...then the tape falls off. Just wish I could do that for all the outdoor lighting. Of course I'm assuming they are mostly talking about the larger quantities of light that come from the screen not little pilot lights...so I guess make them emit more towards the warmer end of the spectrum at night by default? Shouldn't be hard, color balance could be fun though.

    The earth goes around the sun. (As long as I'm presenting shocking info. Although maybe for the rocket flying flat earth guy it would be shocking). Of course my point was they were talking about blue light at night (lots of things are different at night, eating at night causes you to get fatter than the same food in daytime e.g.).

    At least we would know and could do things about it if we choose.

    Wonder if they have plotted the cancer rates from the era when most of the street lights were those blue shifted Mercury lights through the more recent time of the yellow Sodium lights? A lot of homes had those mercury lights as outdoor security lights which probably cast a lot of light into the nearby houses.

    Don't know about the blue, but there are a lot of studies about the overall harm bright outdoor lights do. Probably nobody gave the color temperature of the light much thought.

    Stand in the sun for like 10 minutes and you've already put your cell phone down one on the list of possible things that will give you cancer. Everything on the planet has some sort of chance you give you cancer.

    You just pressed about 200 keys on the keyboard just now. Your chance of getting cancer just increased by 0.000000023%

    Either stand outside in the sun and get cancer or
    Stay inside and get cancer.
    You're dead either way.

    I have 320W of T5 florescent bulbs that are mostly in the blue spectrum (400-450nm) in my rec room. Goodbye cruel world.

    They only use the word "linked", which has no generally accepted scientific meaning, when a study can't even show good correlation between putative cause and effect, let alone causation. So whenever you see that kind of language in a study, you can just dismiss it out of hand.

    Like the early DDT studies.
