Tired, Wired, and Completely Over It
When your body hits empty but your brain refuses to leave the meeting
You know that feeling of being physically DONE?
Heavy limbs, blurry eyes, yawning every few minutes – your body’s sending all the signals.
Yet the moment you get horizontal, your brain turns up the volume. The mental recap starts. Tomorrow’s list assembles itself. You find yourself relitigating a conversation from 11am.
This isn’t insomnia, exactly. It isn’t anxiety, necessarily. It’s its own animal: hyperarousal. And once you understand what’s actually happening, it becomes much easier to do something about.
Your Stress Response Has Been Multitasking All Day
Your autonomic nervous system operates in two modes: the sympathetic branch (alert, activated, ready for action) and the parasympathetic (rest, digest, recover). Achievers often operate from the sympathetic lane, because they’ve got a lot going on. Like a deadline that shifted. An email that required careful wording. Back-to-back calls with no real transition between them. Kids to pick up.
Here’s what people don’t realize: your nervous system doesn’t weigh the severity of the demands it’s managing. An irritating work situation activates many of the same physiological pathways as a physical threat, just at a lower intensity.
But wait, there’s more! Those activations accumulate. After a full day of being “on”, the sympathetic system doesn’t always reset cleanly when your calendar runs out. It keeps going.
So you’re exhausted and wired. These aren’t contradictory. They’re both true at once, and they explain each other.
Relaxation Isn’t the Same as Regulation
The standard wind-down advice – dim the lights, stop the screens, do something calming – isn’t wrong. But it misses something important: if your nervous system is still in activation mode, passive relaxation is like trying to stop a running engine by walking away from it. The engine doesn’t care. Hell, it doesn’t even realize you left!
What’s happening in your body during hyperarousal is the synthesis of a few different things. Cortisol is still elevated from earlier. Heart rate variability, which is a key marker of nervous system recovery, is low. The prefrontal cortex is depleted from the day’s work. But the amygdala, which manages the alarm system, is still running. The brain becomes simultaneously too tired to think well and too activated to stop.
This is why you can be yawning on the couch at 8pm and staring at the ceiling at midnight. Your body wants to sleep but your nervous system doesn’t know the threat level has dropped. It needs a signal.
A Breathing Ratio Your Nervous System Understands
This one may look familiar if you’ve been reading this newsletter for a while. There’s a reason it comes back.
4-7-8 breathing works especially well for the hyperaroused nervous system because of its unusual ratio. Most breathing techniques use even or mildly extended exhales. This one goes significantly further, and the mechanism is worth understanding.
The 7‑count hold helps you slow down and deepen each breath, which supports the calming effect of the extended exhale. That exhale activates the vagus nerve, sending a clear parasympathetic signal through your body. Together, these create a genuine physiological shift, and you might notice yourself feeling more relaxed in just a few rounds.
Here’s the how-to.
Breathe in slowly through your nose for a count of four. Full breath.
Hold at the top for a count of seven. Let it be comfortable.
Exhale slowly through your mouth for a count of eight. Fully empty.
That’s one round. Do a set of four. Start again if you want, taking a break after every fourth round.
Want to get fancy?
Put the tip of your tongue against the roof of your mouth where your two front teeth meet. Inhale through your nose and hold. Keeping your tongue in place through the exhale, make a whooshing sound as the air comes out.
It’s a little weird and a little fun and it just might bring out your inner Darth Vader.
Try it lying in bed, or sitting quietly before you get there. This isn’t a technique for the middle of a hectic day; it’s for times you want to bring yourself down quickly. Perfect when the day is genuinely over and your nervous system hasn’t caught up to that fact yet.
You can’t talk your nervous system out of treating your notifications like a mortal threat. This is your nervous system trying to protect you! Give it some love for doing its job.
And then do some 4-7-8 breathing to send your body a clear physiological message that the threat level has actually dropped.
Rest well. You’ve earned it!

That “engine still running” image feels a bit too accurate… like the body didn’t get the memo that the day ended. Nicely framed. Thank you.
