So cortisol still peaking in the morning, still dropping in the evening.
Wow.
That's very surprising to me.
So the message is if you suffer less than adequate sleep, get someone to take care of everything else.
You better be in a spa.
You better be in a spa, exactly, exactly.
No, and I'm not challenging the result.
I just find it really interesting.
I would have thought that basal cortisol levels would go awry.
Wild.
They're missing a full sleep cycle.
I can only imagine.
Wow.
Okay.
Because my mind always...
goes to, all right, well, we wake up in the morning because of an increase in cortisol, that's circadian, it's not related to sleep per se, it just kind of overlaps with the end of the night's sleep.
If that's independent of sleep and cortisol drives glucose release, we know this, at least in the first study you described, glucose levels weren't altered.
You said it was isocaloric, so people were, it's not like they're eating more.
