"I just sat in front of the computer, so why am I this tired?"
"I thought I was just focusing, but before I knew it, my shoulders and neck were rock solid and the back of my head felt foggy and heavy."
If either of these sounds familiar, it may not be about effort or stamina. Behind the sense that computer-work fatigue is hard to shake lies a bodily mechanism: staring at a screen for long stretches makes it easier for your autonomic nervous system balance to tip out of place.
Why Computer Work Is This Tiring
While you keep looking at a computer or phone screen, your body unconsciously piles up small moments of tension. The eye muscles constantly refocusing, and the neck and shoulder muscles holding the same posture, stay continuously at work. When this continues for a long stretch, the time your sympathetic nervous system stays dominant, keeping your body in active mode, extends, and the switch to your parasympathetic nervous system, which handles relaxation, stops happening smoothly.
This isn't imagination or being soft — it's thought to be the result of the modern, screen-specific load acting on your autonomic nervous system. If you're working under the pressure of deadlines or email notifications, it's even more likely that your brain and body stay in an alert state with no chance to rest.
A Japanese Tradition of Burning Incense to Switch Out of Work Mode
The idea of entrusting a shift in mindset to scent has long been valued in Japan. Heian-period aristocrats are said to have subtly let a scent called sora-dakimono drift through a room, settling both the air of a space and their own state of mind. Incense burned at temples and shrines also served to quietly mark the line between a space and everyday life.
You could call this a culture of drawing a kekkai-like line, "switching from here," using something invisible — scent. Now, when the boundary between computer time and rest time tends to blur, this kind of wisdom for marking a transition with scent is especially useful.
What to Do — Building a Way of Working That Doesn't Let Fatigue Build Up
Deliberately Create Time Away From the Screen
Once an hour, look away from the screen and spend even just a few minutes looking at something far away. This not only eases tension in your eye muscles, but also gives you a chance to change your posture.
Build a Habit of Marking a "Transition" With Scent
Burning incense, or using an item that carries scent, at the start and end of your work makes it easier to signal to your brain "this is work mode now" and "this is rest time now."
Revisit Your Posture and Breathing
Shallow, fast breathing makes your sympathetic nervous system even more dominant. Rolling your shoulders broadly between tasks and taking a few slow breaths can make a difference on its own.
Set a Fixed Digital Detox Time Before Bed
Screen time before bed directly affects how much fatigue lingers the next morning. Try setting your screen aside 30 minutes before bed and replacing that time with scent instead.
Reset With Scent
No.17 Deep Reset suits anyone who spends long hours at a computer or phone and often feels a foggy heaviness in their head. It's a scent built as self-care for facing fatigue from digital environments and resetting your mindset. Burning it at a natural pause in your work, or at the end of the day, works like Japan's tradition of burning incense to settle a space — helping you quietly let go of work mode.
Summary
- Computer-work fatigue isn't imagination — it stems from the load of screen time making autonomic nervous system balance easier to disrupt
- A longer stretch of sympathetic dominance makes the switch to a resting parasympathetic state harder
- Japan has a long tradition, like sora-dakimono, of using scent to mark a boundary in a space or a state of mind
- Build time away from the screen, scent-based transitions, and attention to posture and breathing into your daily habits, little by little
