The "Quick Question" Is Costing You 23 Minutes

Someone taps your shoulder. A Slack notification pops up. "Got a sec?" It feels harmless. It's not. The real math behind a 5-second interruption Researcher Gloria Mark, who has spent two decades studying attention at work, found that after being pulled away from a task, it takes people an average of 23 minutes and 15 seconds to fully regain deep focus. Not to answer the question. To get your brain back to where it was. Here's the part that should worry every manager: most people don't even make it that long between interruptions in the first place. Studies tracking real workplace behavior found workers spend just 3 minutes and 5 seconds on a task, on average, before switching to something else, and that on devices specifically, that window shrinks to barely 2 minutes. Do the math. If refocusing takes 23 minutes and interruptions arrive every few, most people are never actually finishing the loop. They're perpetually mid-reboot. It's not (only) other people's fault Here's the twist: in workplace tracking studies, people interrupted themselves 44% of the time. Not a coworker, not a notification. Just an itch to check email, glance at Slack, or open a new tab. The habit is self-inflicted almost as often as it's imposed on us. Add in the ambient pressure: over half of workers say they feel they need to respond to notifications immediately, and workers switch between an average of 9 different apps per day. It's not weak willpower. It's an environment engineered for fragmentation. Why this is a business problem, not a personality flaw Interruptions don't just cost minutes. UC Irvine research found that after just 20 minutes of repeated interruptions, people reported significantly higher stress, frustration, and perceived workload, even when the total amount of work stayed the same. Fragmented attention doesn't just slow output. It makes the same output feel harder. That's the hidden tax nobody puts on a P&L: work takes longer, feels worse, and the people doing it are more drained at the end of the day than the hours worked would suggest. What actually helps You don't need a digital detox retreat. Small structural changes move the needle: Batch your check-ins. Close email and chat for defined stretches instead of leaving them open all day. Every closed tab is one less self-interruption available. Protect a real focus block. Even 60-90 minutes of genuinely uninterrupted time, phone away, notifications off, is enough to complete a full deep-work cycle instead of endlessly restarting one. Ask before you tap. If you're the interrupter, a two-second "are you mid-focus?" message respects the 23 minutes you might be about to cost someone. Normalize the "not now." Teams that treat a delayed reply as acceptable, not rude, give people permission to actually finish what they started. The takeaway Every "quick question" has a hidden price tag most of us never see. Not the two minutes it takes to answer, but the twenty-three it takes to come back from. Protect focus like it costs something, because it does.
