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

Their control of their blood glucose, not surprisingly, becomes unbalanced.

And they start to behave slightly peculiarly in open field situations.

Huberman Lab

Now, you and I know that when you put a mouse in an open field situation, it's a measure of how confident it feels.

Huberman Lab

So it runs around the edge at first until it feels happy and then it wanders around the middle and the rest of it.

Huberman Lab

Mice under LED lighting do not make that transition from working around the edge and coming into the center.

Huberman Lab

And that is possibly consistent with the notion they have low-level infection, chronic infection.

Huberman Lab

That's all published.

Now, there's some stunning data coming out of another lab.

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

It will come out early next year showing that these same mice...

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

have fatty livers, again, not really desperately surprising.

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

They've got fatty, but there's a clear systemic effect here because their livers are smaller

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

Their kidneys are smaller and their hearts are slightly smaller.

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

With the liver problems, we get a raise in what we'll call liver distress signals, proteins coming around what's called ALT, which tells you your liver is not happy at all.

Interestingly...

Huberman Lab

Where do you also find vast numbers of mitochondria?

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

You find them in sperm.

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

So there is a greater concentration of sperm with abnormal swimming capacity and abnormal morphology in those mice.

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

And the testicles have abnormal morphologies.

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

Now, these are animals that are really run towards the end of their life.

Huberman Lab

Okay, but again, let's put all these things together.
