The way that our lives are right now is really to work against us.

We have traffic in the morning that we have to get up early for.

We come home late, we have a lot of homework, extra work that we have to complete.

That requires light, that requires working on a computer, that moves things forward.

We don't get the benefit of going to bed early.

And what's the first type of sleep that we get when we go to bed?

It's slow wave sleep. And this is the best type of physically restorative sleep.

And then, of course, we need to get up early in the morning.

We're not getting as much sleep because we need to get on the freeway to get to our work because we live in places where housing is cheaper.

But we want to work in places where the cost of living is higher.

Modernity is just crushing us. All of these things are pushing us away from health.

Dr. Schwalt, welcome.

Thank you so much, Kristen.

It's great to be here.

I am so excited for this conversation.

I think we're kindred spirits and that we both believe light is the path to human health and longevity. So I'd love to hear

your thesis around that.

Yeah. I mean, I came into this late. I'm a pulmonary and critical care specialist.

When I joined a group, they said, no, you're going to need to know about sleep. You're going to

have to train in sleep. And I said, okay, I'll do it. And you know, it's interesting. As I began to study

more and more about sleep, those sleep journals became more interesting. Isn't it interesting how that

works? It's so cool. And one of the things that I found was that sleep is highly tied to light, of course, and having light at the right time and having darkness at the right time.
