The science behind shift-work fitness. Circadian rhythms, muscle clocks, cortisol, gut health, and how to reset your body clock.
Circadian rhythms
The basics of circadian rhythm science, and why "just power through" is the worst advice a night-shift worker can get.
Read the post →Muscle clocks
It's not just your brain that runs on a 24-hour cycle. Your muscle tissue does too, and it changes how you should train around a night shift.
Read the post →Gut health
Shift work disrupts more than sleep. Your gut microbiome runs on a clock too. Here's what the early research says, and what's still unclear.
Read the post →Cortisol
Cortisol timing gets blamed for everything from weight gain to burnout. Here's what the research actually says, and what's still unproven.
Read the post →Phase-response curves
Phase-response curves explain why the exact same light exposure can shift your rhythm forward or backward depending on timing.
