Many of us as leaders believe we're effective at "multitasking." The reality, however, is that our brains are just not physically wired to multitask. In reality what happens when we attempt to multitask is that our brain quickly shifts from task to task. This switching from task to task can lead to brain fatigue. It also reduces accuracy and productivity.According to the Center for Brain Health attempting to multitask also causes the build up of the stress hormone cortisol. Over time the increase in cortisol can lead to:
- Decline in memory
- Increased brain cell death
- Decreased neuron activity
- Weakened immune system
- Poor cognitive functioning
- Greater brain atrophy
