Most senior marketing leaders never truly switch off.
They’re simply switching contexts at lower intensity. And, from a neurological standpoint, what we all call multitasking is largely a misnomer. The brain is not performing tasks simultaneously, it's rapidly toggling between them, incurring a measurable “switch cost” each time.
Research suggests context switching can consume up to 40% of productive time, as the brain repeatedly pauses, reloads and reorients between tasks. Even brief interruptions increase error rates and degrade performance, particularly in complex cognitive work.
Over time, this creates what psychologists would recognise as cognitive fragmentation. Attention never fully settles. Part of the mind is always elsewhere, holding onto the last task, anticipating the next. Working memory stays partially occupied, even in moments that are meant to be restorative.
For CMOs, this matters more than it may first appear.
Marketing leadership sits at the intersection of strategy, creativity, commercial pressure and constant input. It is a role defined by continuous context exposure, platforms, teams, data, culture. The result is degraded decision-making. Executive function (planning, problem-solving, prioritisation) declines under sustained multitasking load.
True time off is the removal of context switching entirely.
In those conditions, the brain exits task mode. Cognitive load drops. Attention resets. What returns is the ability to connect ideas and make higher-quality decisions.
As working within the industry becomes more fragmented, senior marketing leaders who can access periods of uninterrupted cognitive recovery will hold a quite the advantage.
