Ep85 Presenteeism: Why Working When You Shouldn't Is Hurting Your Brain

Send us Fan MailEver pushed yourself to work through illness or stayed late just to be present at work and be seen? Your brain might be paying a devastating price.Presenteeism, means showing up physically but functioning below capacity due to illness, injury, or simply staying longer than necessary. This costs UK businesses a staggering £100 billion annually. Yet unlike absenteeism, it remains largely unmeasured and unaddressed in most organisations.The neuroscience reveals why this matters so deeply. When we work while unwell, our brains operate in conflict, diverting precious cognitive resources to manage pain or stress before productive work even begins. The anterior cingulate cortex, which processes both physical and social pain, lights up when we fear letting colleagues down—driving us to show up when we shouldn't. Meanwhile, receiving praise for "pushing through" triggers dopamine rewards that reinforce this harmful pattern.Most alarmingly, chronic presenteeism physically changes your brain. The hippocampus can actually shrink under prolonged stress, affecting memory and learning capacity. Neural connectivity in the prefrontal cortex weakens, reducing judgment, concentration, and emotional regulation. What many attribute to "just getting older" might actually be the cumulative effect of insufficient recovery.The good news? Our brains possess remarkable neuroplasticity. By prioritising psychological safety, resilience training, and supportive policies, organisations can combat presenteeism while enhancing performance. Leaders play a crucial role by modelling healthy boundaries and creating cultures where wellbeing and productivity coexist rather than compete.Ready to transform how you think about rest and recovery?
