Hey everybody, welcome to Help Theory. Today's guest is Harpreet Rye. He's a former investment banker

turned entrepreneur who is the CEO of Aura Ring, a sleep tracking company that is doing its best to

help us all live our best lives. And Harpreet, what I want to know about is why exactly the sleep matter.

It's a loaded question. A great way to start. I think sleep matters for a bunch of different

reasons. I think Sean Stevenson said it really, really well. To your overall well-being and your health

and your performance, sleep probably does have a greater impact than both diet and activity combined.

But the reality of it, we all know it when we get a bad night of sleep. We feel like rap,

right, we're not productive, we're sort of gratitude to the people around us,

can't perform well in the gym, right, and oftentimes just have low energy. So there's a whole host

of reasons on the health side, but also just literally how you feel about life and your mood.

A lot of that has to actually come back to sleep. If you had to push beyond what we know,

because I know people are super tense about what I'm about to ask you, if you had to push beyond what

you know and went into hypothesis or what you suspect, what is it exactly that you think is happening

when we sleep? Sure. So we know that the brain is like cleaning out things, but what else is going on?

I think if you, one way I like to think about it is, your body actually is operating mainly because

of release of certain hormones, at certain periods of time. A lot of that is governed by something called

like a central clock to your body. We call that kind of science circadian biology. It's a relatively

new science. So as you pointed out, there's not a lot we know. But if you want to think about actually,

hey, what time do I get tired? And then when I get tired and I go to bed, what's actually happening?

Why are certain fluids moving through my brain and removing toxins? Why are actually memories

throughout the day being sped up at three times the speed during REM sleep to help you learn?

Why is certain hormones being released to actually bring your heart rate and your blood pressure down?
