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

So first of all, the way you've described it is absolutely the way I think about it.

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

And I think all our colleagues, it's balance.

Huberman Lab

It's balance.

You should be very careful about what you read on an LED box because people are saying sun-like.

Now, I've never found commercially an LED that says that that's really gone anything significantly beyond 700.

Huberman Lab

So, it doesn't matter what they're telling you, I'm exceedingly doubtful that commercially anyone has got anything that does that.

Huberman Lab

Because the only way you could do that is to have a vast array of LEDs in a single device

So I have an LED at 670, an LED at 700, an LED all the way up to over 1,000.

It's not realistic because it's expensive and it draws lots of energy.

And the other thing is that we now have found that the mitochondria knows that it's a compressed load of LEDs because if you put people under a compressed series of LEDs like that...

Huberman Lab

you don't get the same response or the same positive effect as you do if you put them under an incandescent light where the spectrum is totally smooth.

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

There's no ups and downs at the top of them.

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

It's totally smooth.

Huberman Lab

Now, how a mitochondria does that is completely and utterly beyond me.

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

No.

Huberman Lab

And isn't it amazing that mitochondria can sort that one out?

Huberman Lab

And it just makes me feel, by the time it's all over for me, I'll have got one bite at this apple, but there's a load more there that I think we're going to find out.

Huberman Lab

They're doing things that are just inconceivable at the moment.

Huberman Lab

So I think we're going to leave candlelight out of it because to get enough light out of a candle, we're going to have to have copious amounts of candles.

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

Yeah, yeah.
