You close your laptop at 5:30pm and immediately jump into making dinner, helping with homework, or scrolling your phone. Fifteen minutes later, you still feel wired. An hour later, you're physically home but mentally still at work.
We're trying to make an impossible shift. And our nervous systems are paying the price.
The Airlock Problem
Think about astronauts stepping into space. They don't go straight from their spacecraft into the vacuum. They pass through an airlock chamber that gradually adjusts the pressure.
Your mind needs something similar. A deliberate transition between the pressurized demands of work and the open freedom of your personal time.
But most of us try to make the switch instantly. We close our laptops and expect our brains to flip a switch from "work mode" to "home mode" like we're changing channels.
Our biology doesn't work that way.
What's Actually Happening in Your Body
When you're in work mode, your body is running a specific chemical cocktail. Cortisol (your stress hormone) is elevated. Your sympathetic nervous system (the "fight or flight" system) is engaged. Your brain is in a state of focused alertness.
These aren't bad things. This is how you get stuff done.
The problem comes when you try to shift abruptly into relaxation or family time without giving your nervous system the signal that it's safe to downshift.
Dr. Andrew Huberman, a neuroscientist at Stanford, explains that our autonomic nervous system doesn't respond well to instant transitions. It needs gradual cues that the threat (or in this case, the work demands) has passed. Without those cues, your body stays in that elevated state, which is why you feel restless or agitated even after you've "stopped working."
Why Knowledge Work is Different
If you worked in construction or retail, the end of your shift would be obvious. You'd leave the physical location, change out of your uniform, and start the commute home. The work would be visibly done.
Knowledge work doesn't have these natural boundaries. Your work lives on a screen you can access from anywhere. Your projects are never fully "complete" in the traditional sense. There's no factory whistle, no manager saying "you can go home now."
This makes the mental transition harder. Your brain doesn't have clear environmental cues that work is over. You have to create them yourself.
Three Transition Rituals That Actually Work
The goal isn't to find the "perfect" ritual. It's to find something consistent that signals to your nervous system: work is done, you can let go now.
1. The Physical Marker
Change something about your physical state. This could be changing out of your work clothes, going for a short walk around the block, or doing a quick exercise session. Physical movement helps metabolize cortisol and gives your nervous system a clear "end point."
Some people swear by the wardrobe change. Others won't start their evening without a 10-minute walk. Find what feels natural to you.
2. The Reset Routine
Create a consistent 5-minute "closing down" process. Shut down your computer properly. Tidy your workspace. Review what's on deck for tomorrow and write it down somewhere. Clear your desk. Resetting your environment to pre-work time signals to your brain that there is nothing left to do today.
This isn't busywork. You're creating a ritual that tells your brain "we've completed the transition." Dr. Cal Newport calls this a "shutdown complete" practice, and he credits it with helping him maintain strict work-life boundaries despite running multiple demanding projects.
3. The Mental Debrief
Spend 5 minutes processing what happened today and what's coming tomorrow. This could be talking it through with someone, voice recording your thoughts, or using a structured journaling practice (like OFF: A Post-Work Journal).
The key is externalizing those work thoughts instead of letting them loop in your head all evening. Your brain can relax when it knows the information is recorded somewhere outside your memory.
Start Small
You don't need to implement all three rituals. Pick one that feels most doable right now. Maybe it's as simple as changing into comfortable clothes and taking three deep breaths before you leave your workspace.
Do that same thing tomorrow. And the day after.
Your nervous system will catch on. It just needs you to teach it where work ends and life begins.
Your Move
What's one small, repeatable action you could do every day to mark the end of your workday? Not something you "should" do. Something you'd actually follow through on.
Try it for five work days and see if you notice a difference in how your evenings feel.
The work will be there tomorrow. Tonight belongs to you.
