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
