Episode notes

Every single one of our cells has a tiny 24-hour clock that's running non-stop. Circadian literally means about and day. Scientists have been asking, what if you could harness the circadian rhythm to improve health? Could we eat, exercise, or take medications at certain times to optimize their health benefits? Or could you even modify your body clocks by taking a jet lag pill which would switch you immediately from New York to California time?

The concept of having a “body clock” is a familiar one, but less widespread is the awareness that our body contains several biological clocks. Understanding their whims and functions may help us optimize our lives and lead to better overall health, according to scientists.

Every physiological system is represented by a clock, from the liver to the lungs, and each one is synced “to the central clock in the brain like an orchestra section following its conductor,” writes Kim Tingley, a New York Times journalist who explored the effect this knowledge has on how conditions are treated, and spoke to scientists about how misalignment or deregulation of these clocks can have a profound effect on our health.

Exploring the components that dictate our lives, and how they work together like the “gears in a mechanical watch,” Ms. Tingley builds a case for the importance of paying attention to all our circadian rhythms — and not just when it comes to monitoring our sleep.
