Episode notes

circadian rhythms are behaviors or biological processes that exhibit some sort of 24 hour pattern, which means we see the same approximate peak and prof in that pattern every single day. The most common people think of is sleep and wake activity because that's obviously the most interesting to us just immediately. Most species they go get up and go to bed at around the same time every day. But for the most part, our food we were able to hunt during the day or, you know, at the late parts of the day.

Ahh, Daylight Savings Time: does it mess up your brain? What time should you go to bed? Are you sleeping enough? Is shift work really that bad? How dark is dark enough? The wonderful and hilarious Dr. Katherine Hatcher got her PhD in hormones, sleep cycles and circadian rhythms, and helps Alie dissect her terrible sleep habits. We also chat about a tiny magical area in our brains that acts as your body's Big Ben. By the end of the episode, you'll be in footie pajamas eager to change your whole life.
