You power through a ten-hour shift feeling sharp, but the second you walk through your front door, your body completely shuts down. This isn't weakness—it's your cortisol crashing after holding you up all day.

Why am I so tired as soon as I get home from work?

Your body produces cortisol throughout the workday to keep you alert and functioning, even when you're running on limited sleep. The moment you get home, your brain recognizes environmental cues (your door, your couch, seeing your family) that signal you're safe. 

Cortisol drops rapidly, and all the accumulated fatigue it was masking hits you at once. Add decision fatigue from hundreds of micro-choices throughout the day, and you're running on empty by dinner time.

In this episode, you'll learn:

• Why cortisol keeps you functional at work but crashes hard when you get home
• How decision fatigue depletes your brain's glucose reserves throughout the day
• Why this is normal physiology, not a sign you're out of shape or getting old
• Four practical strategies: managing blood sugar, creating transition rituals, timing caffeine, and protecting a 15-minute buffer when you first arrive home

You're not failing your family by being tired. Your body's doing exactly what it's designed to do after a long day of work.
