Yes.

Why? Because cortisol is like basically getting adrenaline in the middle of the night, and so, boom, it wakes you up.

Guess what time it seems to hit? Somewhere between 2 and 3 o'clock in the morning is when we start to see this cortisol hit, which is interesting because it's oftentimes a reaction to either lower estrogen or lower progesterone or irregular estrogen and progesterone.

So one thing that we have happen is basically somebody pushes the awake button in the middle of the night, which is called cortisol.

So that's one thing that we know that happens.

A second thing that we know that happens, I think there's a blood sugar surge.

We see this happen a lot, especially coming out of the last REM period.

Yeah.
