You're Not Doing Two Things at Once — You're Switching
Multitasking feels efficient, but your brain just jumps between tasks. Each jump costs you focus, and notifications keep pulling you back because they feel good in the moment.

What Multitasking Really Looks Like
Stanford researcher Clifford Nass studied people who multitasked a lot and found something surprising: they were actually worse at filtering out distractions, worse at remembering things, and slower at switching tasks than people who focused on one thing. More practice didn't help — it made things worse.
You can walk and talk at the same time because walking is automatic. But real work — writing, reading, analysing — needs your full attention. When you check Slack while editing a document, you're not doing both. You're interrupting yourself. And part of your focus stays stuck on Slack even after you go back to the document.
That means you return at maybe 80% focus, not 100%. Switch fifteen times before lunch and you've spent hours feeling busy while getting little done — and wondering why you're so tired.
Why Notifications Are So Hard to Ignore
Your brain releases a small burst of feel-good chemicals when something new shows up — a fresh email, a ping, a new tab. It's not really about pleasure; it's about anticipation. Something new might be interesting, and your brain wants to check.
The task you should be doing — writing a report, studying, planning — pays off later. A notification pays off right now. Over time, your brain learns to prefer the quick hit. Focused work starts to feel boring, even uncomfortable.
Constant small rewards also shift your baseline mood. When you're not being stimulated, you feel flat or restless. That's one reason heavy multitaskers struggle to sit with a single task — their brain has gotten used to constant novelty.
How to Protect Time for One Task
Staying focused doesn't mean working longer — it means blocking out uninterrupted time. The Pomodoro method (25 minutes on, 5 minutes off) is popular because it matches how attention naturally works. But even a simple 45-minute block with no notifications can change your whole day.
During a focus block: phone in another room on silent, email closed, one tab open, one task from your list. If a new thought pops up — "I need to email Sarah" — write it on paper and go back to your task. You're not ignoring Sarah; you're not letting a notification hijack your focus.
Research found that after an interruption, it takes about 23 minutes to get fully back into a task. So one quick Slack check doesn't cost 30 seconds — it can cost nearly half an hour of broken concentration.
Try counting how many times you switch tasks in one hour. Cutting that number in half within a week is a realistic goal. Pair focus blocks with writing things down so open tasks don't pull you away.
-
Block time on your calendar
Book 9:00–10:00 for deep work. Treat it like a meeting you can't skip.
-
Turn off unnecessary alerts
Every ping trains your brain to expect interruptions. Remove the trigger.
-
One task on screen
Keep only what you're working on visible. Hide everything else.
Common Questions
-
Only for things that don't need thinking — like walking while talking. Anything that requires real attention has to be done one at a time.
-
Most people notice a difference within two weeks of regular focus blocks. Your brain gradually gets used to less constant stimulation.
-
Check messages at set times — say, every 90 minutes — instead of reacting instantly. Let colleagues know when you'll respond.
-
Instrumental music at a moderate volume is usually fine for routine tasks. Songs with lyrics can make reading and writing harder because words compete for attention.
