Study: Light from energy saving LED’s may be giving us cancer

From the “law of unintended consequences” department comes this finding, suggesting that the push for eco-friendly energy savings may be doing more harm to us than good.

Study links night exposure to blue light with breast and prostate cancer

Researchers used images taken by astronauts to evaluate outdoor lighting in Madrid and Barcelona

A study performed by an international team led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the “la Caixa” Foundation, reports a link between exposure to blue light at night and higher risk of developing breast and prostate cancer. Blue light is a range of the visible light spectrum emitted by most white LEDs and many tablet and phone screens. The results have been published in Environmental Health Perspectives.

“WHO’s International Agency for Research on Cancer (IARC) has classified night shift work as probably carcinogenic to humans. There is evidence pointing to an association between exposure to artificial light at night, disruption of the circadian rhythm, and breast and prostate cancers. With this study we sought to determine whether night exposure to light in cities can affect the development of these two types of cancer”, explains Manolis Kogevinas, ISGlobal researcher and coordinator of the study. “We know that depending on its intensity and wave length, artificial light, particularly in the blue spectrum, can decrease melatonin production and secretion”, says Martin Aubé, physics professor at CÉGEP in Sherbrooke, Canada and study co-author.

The study was conducted within the framework of the MCC-Spain project cofunded by the ‘Consorcio de Investigación Biomédica en Red de Epidemiología y Salud Pública’ (CIBERESP), and includes medical and epidemiological data of more than 4,000 people between 20 and 85 years of age in 11 Spanish regions. Indoor exposure to artificial light was determined through personal questionnaires, while outdoor levels of artificial light were evaluated for Madrid and Barcelona, based on nocturnal images taken by astronauts aboard the International Space Station.

Results obtained for both cities show that participants exposed to higher levels of blue light had a 1.5 and 2-fold higher risk of developing breast and prostate cancer, respectively, as compared to the less-exposed population.

Ariadna García, ISGlobal researcher and first author of the study, says: “Given the ubiquity of artificial light at night, determining whether it increases or not the risk of cancer is a public health issue”. At this point, further studies should include more individual data using for instance light sensors that allow measuring indoor light levels. It would also be important to do this kind of research in young people that extensively use blue light emitting screens”.

“Currently, the images taken by the astronauts on the Space Station are our only way of determining the colour of outdoor lighting at a large scale, and the spread of blue light-emitting white LEDs in our cities”, comments Alejandro Sánchez de Miguel, scientist at the Astrophysics Institute in Andalucía-CSIC and Exeter University.

Our church just replaced all the fluorescent lights with LED. Not so bad, except I work in the office 25 hours a week.

Also Gore and the Democrats trying to give us all cancer.

Life just isn’t safe anymore...

I’m sure we can get some bottomless government grants to decide whether we should worry about this. Is 15 years enough time to study it? We can always go longer...

What could be the link between blue light and an internal organ? Why only at night?

Sounds like another government grant to me.

Don't know about the validity of these LED concerns, and have an open mind about such things. That said, walk through any old cemetery and you will see that in the 1600s, 1700s, and 1800s people often died quite young. I'm quite sure that they weren't exposed to LED lighting, or processed foods.

What’s killing me is the constant stress I allow myself to be under just by seeing all the Leftist Satanic crap in politics and on tv.

I’ll use incandescent until I run out. Got plenty of 100s, but am running a little low on the lower wattage bulbs. Still, I don’t change them very often.

Forget it. Climate Change will kill us long before LED’s give us cancer.

Living will kill you especially when the deep state has not yet been incarcerated or otherwise disposed of.

It’s only the crapy LED’s that are that painful arc-welder blue white, most LED lights can be bought in warm spectrum to mimic incandescent, and many can be changed at will as far as color to just about anything you want or even set to shift colors in a cycle. The obnoxious blue spectrum lighting that has been around all my life and I’ve always hated is fluorescent. So, why blame an apparent correlation between high exposure to light in the blue spectrum with various cancers on LED lights? Fluorescent is a far more likely culprit.

Ok, three words/phrases that generally tell you that what you are reading/hearing is complete and utter bullsh*t:

Researchers
International team
Experts

And the more scary and dire the conclusions of their “studies”, the more certain you can be that it is absolute horse manure.

We can look to the Democrats Energy Independence and Security Act of 2007 which banned incandescent bulbs.
