Multitasking Is Draining Your Brain

If you feel exhausted by 2 PM, it’s not just the work—it’s how

you’re working. We use the word 'multitasking,' but neuroscience tells us that the brain

actually cannot do two cognitive tasks at once. Instead, it rapidly toggles

between them. Every time you switch from an email to a text,

your Anterior Cingulate Cortex has to disengage one rule set and activate another.

This creates what researchers call a 'Switch Cost'. This process burns glucose at a

high rate and triggers the release of cortisol, the stress hormone, because your brain

interprets this fragmentation as a chaotic, high-alert environment. So, you aren't just
