Interruption Recovery Cost
After an interruption, it takes significant time and mental effort to fully refocus.
Interruption Recovery Cost
After an interruption, it takes significant time and mental effort to fully refocus.
The Principle
When you're interrupted during focused work, getting back to where you were isn't instant — it takes real time and mental energy, and the stress lingers even after you've nominally returned to the task. About half of all interruptions are self-initiated, meaning this is partly within your control.

Key Statistic
Workers switch tasks every ~3 minutes and experience significantly higher stress from interruptions even without time loss [16]
What The Research Shows
Mark, Gudith & Klocke (2008) found workers switch tasks every ~3 minutes on average. Interrupted workers completed tasks slightly faster but at significantly higher stress, frustration, and effort [16]. The widely cited '23 minutes and 15 seconds' recovery figure comes from Mark's follow-up analyses and interviews rather than the 2005 paper itself [17]. The 2005 study (Mark, Gonzalez & Harris) reported workers switch spheres every ~10.5 minutes and that 57% of working spheres are interrupted [17]. Importantly, ~50% of interruptions are self-initiated. Limitation: observational field studies in specific industries; exact recovery time varies by task type.

Common Myths
Myth: 'It just takes a second to check that notification.' Reality: Even brief interruptions trigger task switching and attention residue. The cost isn't just the interruption itself — it's the recovery time and increased stress afterward [16][13].

How Aftertone Applies This
During Focus Mode, Aftertone can block notifications and display a 'Do Not Disturb' indicator. The app also tracks self-interruptions (when you leave a focus block early) and shows your interruption patterns over time, helping you identify and reduce self-initiated disruptions.
