[quote] A new study from the University of Haifa confirms the theory that bright artificial lighting at night disrupts the body's production of melatonin and increases susceptibility to prostate cancer in men and breast cancer in women. "High power light bulbs contribute more to 'environmental light pollution', which the study has shown is a carcinogenic pollution," said Professor Abraham Haim, who lead the study.
Earlier studies have shown that people living in areas that have more night-time illumination are more susceptible to cancer. The researchers' hypothesis was that light-at-night (LAN) harms production of melatonin, a hormone that is released from the pineal gland during the dark part of the 24h cycle and which is linked to the body's cyclical night-day activity. When this hormone is suppressed, the occurrence of cancer rises.
The new study set out to establish or refute this hypothesis. In order to do so, four groups of lab mice injected with cancerous cells were examined: one group was exposed to "long days" of 16 hours of light and 8 hours of darkness, simulating exposure to artificial light beyond the natural number of light hours in a day; a second group was exposed to the same "long days" but were treated with melatonin; a third group was exposed to "short days" of 8 light hours and 16 dark hours; and a fourth group was exposed to the same "short days" but during the dark hours was exposed to a half-hour interval of light.
The results showed the clear link between LAN and cancer: the cancerous growths in mice exposed to "short days" were smallest (0.85 cubic cm. average), while those mice exposed to the interval of LAN during dark hours had larger growths (1.84 cubic cm. average) and those exposed to "long days" even larger growths (5.92 cubic cm. average).
The study also discovered that suppression of melatonin definitely influences development of the tumor. The size of tumor in mice exposed to "long days" but treated with melatonin was only 0.62 cubic cm. on average, which is not much different from the size of the growth in mice exposed to "short days". The study also found that the death rate in mice treated with melatonin was significantly lower than in those not treated.
The researchers say that their study results show that suppression of melatonin due to exposure to LAN is linked to the worrying rise in the number of cancer patients over the past few years. "Exposure to LAN- disrupts our biological clock and affects the cyclical rhythm that has developed over hundreds of millions of evolutionary years that were devoid of LAN. Light pollution as an environmental problem is gaining awareness around the world, and the World Health Organization has already classified working the night shift as a higher grade of cancer risk," the researchers noted.

Quickly everyone turn off your lights!!!
Don't worry about the sound of breaking glass that's totally fine, also don't worry about the rising crime rate.
So how to make night time mode light bulbs that reduce the intensity but still allow people to see well?
oh god we gona die
I just dimmed my monitor.
Possible disaster averted.
i dont want to leave my computer
melatonin injections please
If I elimate all light bulbs, smoking, electronics, and eat all organic foods... I will be immortal like the caveman.
Thank god I use flux
This has been known a very, very long time.
I thought it was known that light at night distrupts your internal clock and sleeping schedule, part of that being melatonin. That's why people on swing shift and mid shift are worse off in the long run.
Everything causes cancer
Nobody tell California about this, or any lightbulb bought in the US will say "WARNING: THIS PRODUCT IS RECOGNIZED IN THE STATE OF CALIFORNIA TO CAUSE CANCER AND BIRTH DEFECTS."

you know we can see your self-rating antics now right
Fuck it, everything causes cancer now, I just don't care anymore.
I think we should rethink at what point something is carcinogenic.
I'm convinced they just make this stuff up to fuck with us, now.
No, not my beautiful prostate!
Oh shit.
Wait guys don't panic, masturbation prevents prostate cancer right?
Phew, for a moment there I was worried.
Women are fucked though.

Lights towards the red range of the visible light spectrum should be better, because they don't damage the eye's natural night vision capabilities as badly.
Seems like everything causes cancer nowadays.

No, don't you know? Blowjobs prevent prostate cancer in women.
