A recent discussion at the Hay Festival of Literature and Arts has shed light on the significant impact of sleep deprivation on empathy and impulsivity, two crucial factors influencing decision-making both in personal and political contexts. Leading the conversation was Russell Foster, a professor of circadian neuroscience at the University of Oxford and director of the Sleep and Circadian Neuroscience Institute. His insights underline an alarming connection between inadequate sleep and cognitive decline, raising questions about the potential consequences for our leaders and society at large.

Foster reported that sleep deprivation not only diminishes one’s capacity for empathy but also skews perception towards negativity. He noted, “One of the first things that goes when you’re tired is empathy, and what you also adopt is a negative salience.” This concept of salience refers to the heightened awareness of certain stimuli, which, in this case, manifests as an amplified focus on negative experiences at the expense of positive ones. Research supports these assertions, revealing that individuals who have lost sleep are more likely to remember negative feedback while disregarding positive encounters. This cognitive bias can lead to a distorted worldview, ultimately affecting interpersonal relationships and emotional understanding.

Foster’s insights are echoed in scientific research, which shows that poor sleep quality has been consistently linked to increased impulsivity. A multitude of studies demonstrates that sleep deprivation encourages rash decision-making and emotional dysregulation. For instance, one study highlighted how just one night of sleep loss results in a marked increase in impulsive behaviour, particularly in response to negative stimuli. Participants exhibited greater difficulty in controlling their reactions, which can adversely affect social interactions and decision-making processes.

The ramifications of impaired sleep extend beyond individual experiences—Foster highlighted potential implications for political leaders. “For most of us, it’s ‘oh, can I get through the traffic light before it turns red?’ But for our leaders, it’s hugely important [decisions] and I suspect they’re not getting the sleep that they need to make sensible, coherent decisions,” Foster stated. Considering the complex nature of political governance, where decisions can have far-reaching effects on society, the importance of adequate sleep cannot be overstated.

Findings from the empirical literature further bolster Foster’s claims. In one study, significant associations were established between poor sleep and heightened aggression and impulsivity, especially among populations requiring forensic psychiatric care. These insights highlight the urgency of addressing sleep-related challenges, particularly in high-stakes environments where emotional regulation is essential for sound decision-making.

The interconnectedness of sleep, empathy, and impulsivity raises essential questions for both individuals and society. Poor sleep can distort one’s emotional responses, leading to increased aggression and impulsivity—factors that could exacerbate societal issues like political polarisation and social unrest. As the dialogue surrounding mental health and wellbeing continues to evolve, perhaps a focus on sleep hygiene should become a paramount concern not only for individuals but also for institutions that influence our collective lives.

Foster’s upcoming study examining the sleep patterns of politicians is eagerly anticipated, promising to provide further insights into the intricate relationship between sleep and decision-making in leadership roles. As the Hay Festival continues to engage audiences with thought-provoking discussions, the connection between our health and our societal structures remains a pivotal theme, urging us to reconsider the essential role sleep plays in shaping our interactions and choices.
