Huberman Lab · Using Red Light to Improve Metabolism & the Harmful Effects of LEDs | Dr. Glen Jeffery · 1 Dec 2025 podcast

And some people, we've been approached by a few critical care units saying, what about changing our lighting?

I mean, the architects have taught me one or two things.

So they say cost to me because they're commercial.

So they say things like, okay, well, if that gets your patient out of intensive care unit one day earlier, what does it save you?

With one group of architects, we've talked about changing the lighting in a building to having major refurbs on it.

And the owners are, they're going, oh, do we need this, et cetera, et cetera.

And the architect turned around and said, how many days did you lose sickness in this building last year?

And of course they didn't know the answer, but it put them really on the spot.

But the architect said, you should look at the larger economic model here,

And that includes the health, perceived health of the individual.

But it may have beneficial effects for you in terms of reducing costs.

And I think they put their finger on that really quite sharply.

Well, I am 100% behind the idea that firstly, that this can change public health.

And secondly, that it should be done at almost zero cost because that is a potential.

So if you look at, say, a number of my colleagues, and this includes myself, in the kitchen, I have got a halogen lamp.

So when I get up in the morning and you're spending that 45 minutes that really should be 10 minutes, but you're faffing around doing stuff, there's a halogen lamp there on at the right time.

It's not desperately bright, but it's there at a critical time during the day.

What color does it appear?

Ordinary white light.

But it's full.
