Interruptions reduce the quality of your work
Several authors have advocated blocking time during you workday for working uninterruptedly. Amabile & Kramer (2011) say, on the basis of their research, that this is a condition for making progress in what is meaningful to you. Newport (2016) claims that working long and focused without interruptions leads to a dramatic increase in productivity and work satisfaction. Research by Sophie Leroy has shown that when you pick up a task again after an interruption there will be what she calls an attention residue. This means that part of your mental energy is still focused on what you were doing during the interruption. The interruption harms your deep focus.
