Every Cell in Your Body Has a Clock

Circadian rhythm isn’t just controlled by your brain. Every cell in your body runs on a 24-hour cycle, including your muscle cells.
Karyn Esser is the chair of the department of physiology and aging at the University of Florida, and she’s a leading expert on circadian rhythm in muscle cells. Karyn's problem is this: How does the circadian rhythm in muscle cells change as we age, and how does exercise help keep our system in sync?
In this episode, Karyn explains:
How every cell in your body has a clock in it
How muscle clocks prepare cells for work and schedule recovery during rest
How age affects these clocks’ ability to regulate effectively
Why exercise can improve clock function
Why jet lag and late-night eating can put your body clocks out of sync
