So the oxygen level, so you're mildly hypoxic, which leads to brain fog, it leads to low energy and it also interrupts the sleep.

You know, I very often get asked the question, why do people that are the most exhausted sleep the worst?

And the reason for that is that you're exhausted because if you've known somebody or you've ever had the misfortune of being anemic,

When you have anemia, you're exhausted all the time.

You have no stamina, no energy.

You don't have that positive aggression towards working out.

You're walking up a flight of steps.

You feel exhausted.

So that's anemic state.

That does show up on labs.

But when you're hypoxic, when you're just low on blood oxygen, low on red blood cells, low on hemoglobin, which happens when your testosterone tanks,

then you're tired.

But what happens when you go to sleep?

Your respiratory rate starts to drop.

As your respiratory rate starts to drop, your breathing is more shallow.

As your breathing is more shallow, you're taking in less oxygen.

Think about every time you expire air from the tip of your lips all the way down to the lobes of your lungs, that's all expired air, that's carbon dioxide.

So if you're breathing very shallow, a lot of what you're breathing is just that carbon dioxide.

your brain ends up waking you up at night and the way it wakes you up is it pulses cortisol.

And so, when you're exhausted during the day, you also don't sleep well and you would think, well, if I'm really exhausted, the thing I would probably do the best is sleep.
