When ‘Go Mode’ Forgets How to Stop: Understanding the Effects of Burnout - with Erin Shah
Running on Empty: The Science of Burnout
What if being tired all the time actually isn't really about sleep at all? That's burnout, and it's sneakier than exhaustion. It creeps in, disguised as "just a busy season," until one day even easy things feel impossible.
Burnout has a reputation as a purely mental thing — a mindset problem, a motivation problem – but there's a difference between being tired and actually "running on empty". Burnout is psychological, yes, but it also lies within your hormones, your sleep cycle, and a stress system that was never designed to stay switched on this long.
Stress, biologically speaking, is meant to be short. A spike, a response, then recovery. Your body releases cortisol (its main stress hormone) to help you deal with a demanding moment, then it's supposed to settle back down once the moment passes. Burnout starts when that "settle back down" part never gets to happen. Ongoing, unresolved stress keeps this system firing well past its intended use case, and over time, that constant activation starts to show up physically rather than just mentally.
Disrupted cortisol rhythms are linked to knock-on effects across sleep quality, energy levels throughout the day, and how quickly the body recovers from everyday demands. It's less like one thing breaking, and more like a chain reaction — one system throwing off the next. This is exactly why "just get more sleep" or "just relax" often doesn't cut it once things are this out of balance. The system needs consistent, repeated signals that it's safe to downshift, not simply just a single weekend off.
Giving the System What It Actually Needs
Recovery, biologically, comes down to giving the body real, repeated opportunities to shift out of "go" mode:
Consistent sleep: the single highest-leverage lever, since cortisol and sleep regulate each other
Regular movement: even light activity helps regulate stress hormones over time
Real pauses: moments where the body actually registers "off," not just a change of task
Nutritional support: magnesium and B vitamins are commonly used to support energy metabolism and nervous system function during demanding periods
Adaptogenic herbs: ashwagandha and similar herbs are traditionally used to support the body's resilience to ongoing stress
None of this is about overhauling your entire life. It's about understanding that a stretched-thin stress system responds to consistency — small, repeated signals of recovery, rather than one big dramatic fix.
Sometimes the most productive thing you can do for your body is, quite literally, nothing at all.
