You know why?

Because like right now, 940p up

we're kind of doing shift work right now.

Most people are on a shift work schedule now in the world.

This is true.

We think of shift workers as only the people who are up in the middle of the night and sleeping during the day, but most people are doing shift work.

The criteria for shift work is at least a two hour variant, at least in the US, a two hour variance in the sleep wake cycle, more than three nights a week.

Anyone here go to sleep every night, same time, wake up every morning, same time, never stay up later than that, more than two nights a week?

Okay, most people are doing shift work nowadays.

They're just on their phone or they're on their computer.

And I'm not going to argue that, you know, you shouldn't.

Many times that's me as well.

So here's what we do know.

We did a whole episode on shift work, but I'll try and summarize some of the key points.

You want to have your cortisol elevated early in the day and then subside across the day.

That's the ideal pattern of cortisol release.

Cortisol is a great thing when it's high and then tapers off from early day into the later day.

It's a bad thing if that cortisol peak is shifted late.

That cortisol peak is coming every 24 hours.

You don't have a choice.
