So sleep is when we're repairing the powers of both the mind and the body. Sleep is when we reduce inflammation, repair tissues. The discovery of the glymphatic system in 2012, 2013 is this passive channel that runs alongside our arteries and veins in the brain that fills with fluid when we're in deep sleep and allows a washing out of debris we may have accumulated during the day.

So all those bad thoughts get washed out. Well, not the bad thoughts. Well, the bad thoughts, no, but the amyloid plaque, that sticky plaque that we secrete in response to inflammation or injury, if it accumulates, of course, it can damage surrounding neurons and is associated with neurodegenerative disease and Alzheimer's disease.

It's definitely playing a role. And this concept of bidirectionality, we know that sleep disruption, circadian rhythm disruption, sleep apnea is present in two-thirds of people with insulin resistance, prediabetes, diabetes. And it is a chicken and the egg thing. It is driving the bus. We used to think, well, you get the sleep apnea because you have insulin resistance and gain weight.

But if you have disrupted sleep, your insulins are higher, your cortisol's are higher, your glucose is higher, you're looking for highly processed, quick, energy dense foods and less able to resist them.
