Many of us have them in our homes and at offices — but a neuroscientist warns that one household staple may be a major threat to our health.
Glen Jeffery, a professor of neuroscience at University College London, is sounding the alarm about what he calls a “clear and present public health emergency” that no one seems to be talking about.
He has gone so far as to compare the item to asbestos — once widely used in building materials before people realized it can cause issues like mesothelioma and lung cancer.
The health threat? Energy-efficient light-emitting diode bulbs, which are present in schools, offices, hospitals and nearly half of US households — and which Jeffrey claims could raise the risk of diabetes and other metabolic disorders.
“LED lighting is damaging mitochondria and therefore there is no question you’re damaging systemic health,” Jeffrey told The European. “This is a clear and present public health emergency and we need to take action.”
One study found that daily exposure to short-wavelength blue light reduced measures of mitochondrial activity by about 50% in mice. Another study found that exposure to blue-enriched LED lighting altered activity, metabolism and liver function in mice.

Thank you very much and God bless you,

Did he recommend going back to candles and reducing electricity use?
.
Many moons ago, we stocked up on incandescent bulbs - 25w to 100w.
Do LEDs still have mercury? If the LED bulbs are from the Chicoms, would you believe their labels?
Thanks Al Gore... You’ve ruined it for future generations.
Thanks Al Gore... You’ve ruined it for future generations.
The globalist elites demanded LED.
So what is the alternative to LED bulbs
Great we just build a new house with industrial quality LED fixtures
“”””Do LEDs still have mercury?::::
You are confusing LEDs with the old squiggly bulbs CFLs.
Holy crap!
They outlawed incandescents and stopped all manufacture. Now we gonna all die!!!
Our government hard at work one more time......
There ain't none. Republicans joined Democrats in banning incandescent bulbs.
This sounds like more crap to me. First, many LED bulbs have all kinds of different color temps. Sounds like he’s pickign the worst one to do a study with.
I also remember when they said our screens will make us all blind because of blue light.
Same here.
Normal LED bulbs. This article/test is crap meant to scare people.
Pick pretty much anything.
Scientist A: It’s good for you.
Scientist B: It’s bad for you.
Scientist C: More study is needed.
There are of course things that are good for you, and things that are bad for you. But it’s often tough to sort through all the chatter to tell which is which.
Including the computer monitor you’re reading?
Here’s your sign. https://www.popsci.com/environment/light-bulbs-sustainability-energy/
“Incandescent bulbs use more energy and produce more heat due to their engineering designs,” says Paul Foote, energy efficiency and conservation specialist at the University of Illinois at Urbana-Champaign. It’s important to shift to more energy-efficient alternatives to reduce the environmental impacts of incandescent bulbs from the utilization of fossil fuels for electricity, he added.
What we had before, incandescent. One of the few things Trump knocked out of the park was signing the EO “Unleashing American Energy” I just ordered a bunch of incandescents. LEDs are trash and a public health menace.
Amazon’s incandescent bulbs never work longer than a few days. Trump made them legal again - why isn’t anyone producing new one?
