There Are 4 Types of Tired—Discover Yours To Get Your Energy Back

Liz Moody opens with a confession: she recently canceled plans with friends three times in one week—not because she was too busy, but because she was "literally just too tired." The frustrating part was that she was sleeping well, exercising, eating well, and still exhausted. That contradiction sent her into the research, where she discovered something most of us miss: there isn't one kind of tired. There are four. And if you treat the wrong one, you stay exhausted.

The Four Types and How to Spot Yours

Moody asks listeners to pick the scenario that feels most familiar. Scenario one: you're wiped after a day of meetings, Zoom calls, emails, and chores. Your brain is buzzing but not thinking—you can't even decide what to eat for dinner. You end up scrolling or watching TV because you're too fried to do anything else. That's input tired—too much stimulation with no processing time.

Scenario two: you might not have had many tasks, but you've been coordinating everything in your head—reminding your partner, tracking deadlines, managing doctor's appointments. Everyone around you feels annoying. You stayed calm in a difficult conversation but wanted to scream. You're the person everyone leans on, and nobody asks how you are.

Ever sleep in on a Saturday and still wake up exhausted? Or finally take that vacation you’ve been dreaming about, only to come back feeling like you need another one? Or maybe you cancel all your plans to stay home and rest, and somehow end up feeling even worse. Been there, done that, got the T-shirt. So I got curious (as I do) and dove into the research. Turns out, there are actually four totally different types of tired: Input Tired, Emotionally Tired, Physiologically Tired, and Existentially Tired.

If we don’t know what kind of tired we’re dealing with, we end up throwing the wrong solutions at it—and then wonder why nothing actually helps. In this episode, I’m breaking down how to figure out exactly what kind of tired you are, so you can finally get the kind of rest that makes you feel energized again. Because you deserve to feel GOOD, not just a little less tired.
