Research shows that your awareness is going to follow a circadian rhythm. There are certain hours of the day that your brain is just primed to work faster. And similarly for your muscles and the other elements that affect your speed and your strength and your endurance. And this depends on your personal body clocks. So again, that chronotype curve, depending on where you fall on that,

those hours of the day might be different. When we throw our circadian system out of whack,

so many potential health repercussions can come. And scientists are linking more and more to

circadian disruption. Metabolism, digestion, our immune system, our ability to be alert, all these things are tied to

our circadian clocks.

So have you ever had one of those days where nothing seems to like your mind is foggy, your

energy is zapped, everything feels like an uphill battle. And then on the

flip side, I'm sure you can recount periods where you were just simply firing on all cylinders,

razor-sharp focus, boundless energy reserves, able to handle stress, solving problems with ease,

and operating at your peak. What if I told you the difference doesn't necessarily come down

to luck or willpower, how smart you are,

how hard you work, that we each have a powerful internal clockwork, regulating our physical,

emotional, and cognitive capacities in a cycle. And when we live in harmony with this

inner timekeeper, we unlock all of this powerful capacity, but when it falls out of sync,

everything becomes an uphill battle. So maybe you often drag in the mornings, no matter the sleep

that you've had, hidden afternoon slump, or surge with energy in the late evening as others wind

down. These are hints that your circadian rhythms, your body's biological

clocks may be misaligned with the choices you're making the way you're living your life and

the way you're even working. My guest today understands these rhythms intimately.
