Shift workers have a serious problem, which is that late peaks in cortisol are kind of paramount in all forms of shift work.

And so what you need to do is to put yourself ideally in lighting conditions that limit the amount of blue light coming in at night or when you're doing that shift work.

Now, you have to do your work.

And I think in the next two years, if I have my way, one idea that I'd like to embed in people's minds is,

You know, we hear a lot now about how hyper-processed foods and highly processed foods are bad for us, sort of empty calories.

What are empty calories?

It's foods that are very calorie dense, but micronutrient poor, right?

That's what it really is.

It's also the quality of food issues and people get, you know, like, let's please not have the seed oil debate.

It's like people get really into this and it's unclear to me still and okay.

But we sort of think of empty calories like alcohol, sugar, et cetera,

Calorie-dense, micronutrient-poor.

Light can be viewed in much the same way.

These days, we live in a very blue-light-rich world.

A lot of blue light, so short-wavelength light, blue light, UV light.

And by the way, in sunlight, especially down here, it's very UV-rich, blue, which is great during the day, especially when it's offset or, sorry, when it includes long-wavelength light.

Full spectrum light.

By the way, for everyone that's obsessed with red light, and I love red light and red light therapies, remember the best source of red light is the sun.

It's full spectrum light.

It includes red.
