But we could talk about why that would be because there's actually a circadian rhythm element to why we get congested at night and why it clears up in the morning.

Really?

Why is that?

Well, I don't want to fully divert the conversation into that, but basically it has to do with, here's a quick little teaser.

Your immune system is nocturnal.

Your immune system is nocturnal.

And then when you wake up in the morning and you get that glorious morning sunlight, right?

You actually are triggering the release of cortisol.

Cortisol is your body's prednisone.

It's an anti-inflammatory.

So you wake up in the morning.

This is why also you go and you get a good workout.

and you go to bed and you're not sore and you wake up and you are sore, you feel that.

Why is that?

Because your immune system is active at night.

So our body was actually very beautifully designed because if your immune system was doing its maintenance work during the day, it would cripple you.

It would affect your energy levels, your focus, your ability to think.

By the way, now I'm starting to describe some of the symptoms that I was going to get at.

Right, it would affect those things and you wouldn't be able to really be optimally functioning as a human So the way that our biology was designed which is like, you know to me like awe-inspiring beautiful is that when we're asleep

During that time where we're not really moving around, that's when the immune system steps up to basically like take care of its maintenance work, which includes like if you exercise, it's helping to basically build the muscle mass and restore those muscles because exercise is actually like a form of micro injury, right?
