Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

So nothing really changed in our world until around 2000.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

As we get to 2005, we're starting to find that the incandescent lights with their loads of infrared start being pushed off the market.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

Yeah, exactly.

So when we use LEDs, the light found in LEDs, when we use them, certainly when we use them on the retina looking at mice, we can watch the mitochondria

gently go downhill.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

They're far less responsive.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

Their membrane potentials are coming down.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

The mitochondria are not breathing very well.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

Watch that in real time.

Huberman Lab

Under LED lighting.

Huberman Lab

Under LED lighting at the same energy levels that we would find in a domestic or a commercial environment.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

That's very concerning to me.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

It is.

Huberman Lab

It was never picked up.

Then also, if you do experiments, say, for instance, on flies,

Huberman Lab

Flies don't live as long under blue light.

Huberman Lab

Their mitochondria, again, decline quite markedly.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

You produce less ATP.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

If you look at mice, you find mice start putting on a lot of weight.

Huberman Lab
Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery

They start putting on a lot of weight because their mitochondria are not taking that glucose out and it's being deposited as fat.
