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

Yeah, I think I would say it's improving the function and it's influencing the more mitochondrial proteins to be synthesized.

So we've got an immediate effect and we've got a longer term effect as well.

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

It makes sense once you hear it.

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

And why the hell did we not think about that five years ago?

Huberman Lab

Scientists make really big mistakes in the pathways that they follow.

Huberman Lab

And they don't talk about their mistakes, but their mistakes are every bit as important as their great results.

Why didn't we think about water?

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

Because our minds were trapped in a certain pathway going down a certain alleyway.

Huberman Lab

And so whatever you think about the water hypothesis, the key point is that improvements in function as a consequence of exposure to longer wavelengths like correlate tightly with what water absorbs.

Huberman Lab

So, okay, that's a big one.

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

That's a big one.

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

That is there.

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

We know that's true.

Huberman Lab

You can pull it apart and find the things called water holes, where there are places where water absorbs a bit more than it does in other places.

Huberman Lab

But fundamentally, the absorption of long wavelength light fits water.

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

Okay, so let's stand you out.

Huberman Lab

Let's strip you off and stand you out in sunlight, you know, 12 o'clock in July.

Huberman Lab

The vast majority of long wavelength light is being absorbed in the body.

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

So what we assume is that it has a very, very high scattering ratio.

Huberman Lab

So the vast majority of that long wavelength light is going to get through into your body and it's going to bounce around.
