How many seconds of delay does multitasking after a notification add on average?

How Much Cognitive Damage Does A Phone Notification Actually Do?

Multitasking after a notification adds an average of 23 minutes and 15 seconds of delay to regain full deep focus[1][2]. This time cost measures the mental recovery required after an interruption rather than the brief duration of the notification itself[3].

In addition to this refocusing time, a single smartphone notification causes a transient cognitive slowing lasting approximately seven seconds[4].
