When performance is not important

“Multitasking will always impair performance,” advises Begeti, “Just because we are able to multitask, it doesn’t mean that we should.” But if no one is going to care if the task you’re busy with isn’t done perfectly, then it’s OK to let your mind wander to other jobs.

When a task is straightforward and repetitive

Frequently tasks such as household chores can be carried out using the habitual part of our brains, so we’re essentially on autopilot, therefore not putting undue stress on our grey matter.

When our job absolutely requires it

Emergency workers such as doctors and firefighters clearly need to be able to think fast. “⁠Some jobs require us to multitask or, more accurately, attention-switch, where we flick our attention between multiple things,” explains Begeti. “This is definitely the case in my day job where I manage multiple patients and constantly prioritise according to urgency. That being said, while this is important in dealing with emergencies, a complex diagnosis will still necessitate giving the patient my undivided attention.”

Put simply, the majority of us could do with less attention-switching behaviour and more monotasking. Something to bear in mind over the festive season, and beyond – if only for your brain’s sake.
