And so that's the way, that's the old- Is that, so why do we have preferences for sleeping position? Is this chronotype? Is this just habitual?

Can we train ourselves up to be- Usually based on your skeletal ergonomics and how you want to sleep. It's also in part driven absent of your body based on your mattress.

And so that's why, you know, having a mattress that's at least supportive enough where you don't get that banana bowing, because if you are a front sleeper and you're sleeping on a poor mattress, then all of a sudden you just get this every night, this bending of the spinal cord and you're lying there.

I might just say, okay, today for eight hours, I'm going to have you compressed into this banana shape lying on your front. And then at the end of that eight hours, get up and, you know, do 10 jumping jacks and feel great. Not so much. So you've got to be mindful of the position. So I would say sleeping on your back, if you're a snorer, not so great.

There is some evidence that sleeping, and I'm going to forget which side it is now, I'm trying to think of my anatomy, but sleeping, I think it's on your left side, based on how your gastrointestinal system is working, leads to a greater degree of GERD, which is gastric reflux. In other words, getting heartburn, just get reflux. Interesting. So that's...

The second one though, really, that I was going to mention is sleeping on your front or on your back may not necessarily be ideal because what they found is that during sleep, and this is a quick tangent, I'll come back to it, but another one of the new functions of sleep is brain cleansing.

That when we go into sleep, your brain essentially has this sewage system that kicks into high gear and it washes away all of the metabolic detritus that's been building up across wakefulness. Because from a biochemical perspective, wakefulness is low-level brain damage. Sleep is your sanitary salvation.
