The context switch tax (and how to pay less of it)

You answer one message in the middle of a report, and the report is gone. Returning means rebuilding: what was the point, where was the sentence, what came next.

That rebuilding time is the context switch tax. For ADHD brains it runs higher, because working memory holds less and drops faster — so every interruption costs a re-entry fee you never planned to pay.

Multiply it across a day. Thirty small switches can quietly consume the hour you thought you spent working.

None of this means you are bad at focusing. It means switching has a price tag, and price tags can be managed once you can see them.

You cannot remove the tax, but you can pay it in bulk. Grouping similar tasks means one reload instead of a day of constant re-entry.

• Messages and email in set windows, not a background drip.
• Calls stacked together, with a buffer after the last one.
• Small admin swept into a single block, once a day.
• Creative or deep work given its own unbroken stretch.

A day with three switches beats a day with thirty. Same work, same hours, far fewer tolls.

Before you switch — voluntarily or not — spend ten seconds writing where you are. “Editing section two, next step is the intro paragraph, source is the email from Sam.”

• One line on paper next to the keyboard works fine.
• Write it the moment the interruption arrives, not after.
• On return, read the note before touching anything else.

Some work only happens in long, unbroken stretches. Give that work one protected block per day and treat intrusions as the expensive events they are.

• Close the inbox and silence the chat for the block.
• Park the phone out of arm’s reach.
• Keep the border note beside you for thoughts that try to pull you out.

One protected hour outperforms four perforated ones. The work is not harder in that hour — it just finally gets to finish loading.
