Running on Empty: What Kind of Tired Are You?
By Natalie Centers
Back-to-school season often marks the unofficial end of summer and the beginning of that ever-creeping feeling that fall is about to get really busy. Schedules fill up, responsibilities pick up, and, before you know it, you find yourself running on empty.
Before you hit that limit, the Mental Health Special Interest Section (SIS) wants to encourage you to pause for a moment and check in with yourself. Not just “Am I tired?” but “What kind of tired am I?”
You often think of energy as one big tank. But fatigue is actually much more complex. You can be physically rested but mentally drained. You can have plenty of physical energy but feel emotionally depleted. You can know exactly what needs to be done but have absolutely no motivation left to do it.
Researchers describe this as multidimensional fatigue—the idea that fatigue can show up across different areas of our lives, including physical, mental/cognitive, emotional, motivational, and activity-related domains. In other words, not all “tired” feels the same, and not all “tired” requires the same kind of recovery.
So, What Kind of Tired Are You?
Physical fatigue
Your body feels depleted. You may feel heavy, weak, sluggish, or like even basic movement takes more effort than usual.
What might help: sleep, nourishment, hydration, gentle movement, or simply giving your body a break.
Mental/Cognitive fatigue
Your brain feels like it has reached its limit. You may have trouble concentrating, making decisions, remembering things, or taking in more information.
What might help: reducing decisions, stepping away from screens, doing one thing at a time, taking quiet time, or giving yourself permission to stop processing.
Emotional fatigue
You still have things you could physically do, but you don’t have the emotional capacity. You may feel irritable, overwhelmed, numb, or unusually sensitive.
What might help: connection with someone safe, solitude, boundaries, emotional expression, or doing something that feels comforting rather than productive.
Motivational fatigue
You know what needs to be done, and you may even have the physical and mental ability to do it, but you just can’t seem to make yourself start. Everything feels like effort.
What might help: lowering the bar, breaking something into a very small first step, changing your environment, or taking genuine rest instead of forcing yourself through it.
Creative fatigue
Your brain feels tapped out when it comes to generating, imagining, problem-solving, or creating. You may notice that you just don’t have any ideas left.
What might help: novelty, play, inspiration, unstructured time, changing activities, or doing something without an expectation of producing anything.
The OT Perspective: It's About Intentionality
As masters of common sense, we’re probably not going to tell you anything here that you don’t already know. These suggestions aren’t novel, and they’re definitely not rocket science. You already know that sleep helps when you’re physically tired, quiet can help when you’re mentally overloaded, and connection can help when you’re emotionally depleted.
The value isn’t necessarily in discovering something new. It’s in being intentional about noticing what you need and choosing a response that actually matches it.
That’s where the OT concept of the just-right challenge comes in. Too little demand can leave us disengaged; too much can leave us overwhelmed. The goal is not to eliminate every demand from our lives but to find the right balance between challenge and capacity.
As fall gets busier, maybe the question isn’t “How do I fit everything in?” Maybe it’s:
“What is my capacity right now, what is asking for my energy, and what small adjustment might bring those two things a little closer together?”
Because sometimes the answer isn’t “I need more rest.”
Sometimes it’s “I need a different kind of recovery.”
