Harm from blue light exposure increases with age, research suggests

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research suggests.

Jaga Giebultowicz examined the survival rate of flies kept in darkness and then moved at progressively older ages to an environment of constant blue light from light-emitting diodes, or LEDs.

The darkness-to-light transitions study involved blue light's effect on mitochondria.

Mitochondria act as a cell's power plant.

In earlier research, Giebultowicz showed that prolonged exposure to blue light affected flies' longevity, regardless of whether it shined in their eyes.

"The novel aspect of this new study is showing that chronic exposure to blue light can impair energy-producing pathways even in cells that are not specialized in sensing light," Giebultowicz said. "We determined that specific reactions in mitochondria were dramatically reduced by blue light, while other reactions were decreased by age independent of blue light. You can think of it as blue light exposure adding insult to injury in aging flies."

There is evidence suggesting that increased exposure to artificial light is a risk factor for sleep and circadian disorders, Giebultowicz said.

"Our previous work demonstrated that daily lifelong exposure to blue light, but not other visible wavelengths, has damaging effects on the brain, motor abilities and lifespan of the model organism," Giebultowicz said. "Now we're reporting that the damaging effects of blue light on the flies are strongly age dependent—the same length of exposure to the same intensity of light decreases lifespan and increases neurodegeneration more significantly in old flies than in young ones."

The flies exposed to blue light showed damage to their retinal cells and brain neurons and had impaired locomotion—the flies' ability to climb the walls of their enclosures, a common behavior, was diminished.

They suggest wearing amber lens eyeglasses when working with your phone or computer and setting the devices to reduce blue light, at least in the evening.

Additionally, note that lutein and zeaxanthin are known to help eye cells stay healthy even when exposed to blue light.

Apparently, lutein and zeaxanthin and N-acetyl-cysteine (NAC) all can help with various destructive and inflammatory processes in our eyes.

“ the flies’ ability to climb the walls of their enclosures, a common behavior, was diminished.”

When I’m climbing the walls I just break out some weed instead of blue light

light-emitting diodes, or LED shorten your life span which is why they banned incandescent bulbs

The “famous” Film director from the first wave of German Expressionism. She lived until age 101.
I recall seeing a photo of Leni and Mick Jagger diving off a high rugged cliff into the ocean.

There seems to be another story with the same title.

This one with the crystal grotto sounds good.

And she did her own stunts as an actress — which in this movie include some impressive freestyle rock climbing.

Apparently Hollywierd saved her from being executed as a war criminal because it saw her as one of their own.

It doesn’t matter, climate change is going to kill us in 8-1/2 years anyway.

Okay, so here’s another destructive thing we can blame the libs for... A few years ago Congress demanded an end to incandescent lightning and a reliance on new tech, i.e., LEDs. As a result we’re all going to go blind. BTW,it was about the same time that Congress mandated toilets that you have to flush twice to get rid of your floaters. You know, because the old inefficient style toilets used too much water.

“Flush twice for Gore” was the old saying.

Hmm…Similar to the effects of blue politics.

I agree with the findings. Hence my propensity to run from the popo with their deadly blue lights flashing trying in vain to reduce my superpowers.
