And so they had all these other factors controlled.

The only difference was basically where they were sitting, right?

If they were sitting in artificially lit or in front of a window.

And what they showed was that when the participants sat in front of the window, they had an increase

in the normal glucose range.

So these participants were in normal glucose range.

So what that means is basically their glucose was in sort of where we want it.

It was in for where we want it for longer periods of time than compared to when they were in the artificially lit environment.

They also saw that there was a lower 24-hour glucose variability.

So variability in glucose fluctuations, there is a decrease in that, which is what we want.

That is a sign of healthier metabolic health.

And then the participants, when they were exposed, when they were in front of the window,

increased whole body fat oxidation.

So they were utilizing fat more than they were carbohydrates.

which is another sign of healthier metabolic function.

And so we have all these different outcomes.

They also showed, similarly, that the people that were working in front of the windows also had higher levels of melatonin at night, sorry, pineal melatonin, so the melatonin that makes you fall asleep, which just confirms what we already know.

We know that if you get more sunlight during the day and in the morning, you have higher peaks of melatonin at night, which is what you want.

They also looked at...

the peripheral circadian clock of their muscle cells.
