Pulling an All-Nighter? Scientists Recommend You Shouldn’t Do This the Next Day

Pulling an All-Nighter? Scientists Recommend You Shouldn’t Do This the Next Day
Share on FacebookShare on Twitter

Student All Nighter

New research highlights the detrimental effects of sleep deprivation on decision-making and emotional well-being, emphasizing the importance of adequate sleep, especially for those in high-stress jobs. The study suggests that sleep loss impairs neural response to risks and decisions, underscoring the need for effective sleep management in critical professions.

Research highlights the significance of sleep for cognitive performance and emotional well-being, particularly for individuals experiencing stress.

Politicians, military leaders, and emergency service workers are among the professions advised by a University of Ottawa study to refrain from making critical decisions following a sleepless night, highlighting the impact of sleep deprivation on high-stress roles.

We all understand the power of sleep and the vital role it plays in human health, cognitive performance, and in regulating our emotional well-being. Numerous studies into a lack of sleep have shown drops in neurocognitive functions, particularly vigilant attention, motor responses, inhibition control, and working memory. Despite this, sleep loss continues to challenge public health and affect people of all ages.

Sleep and risky decision-making

With little insight into the impact of a lack of sleep on risky decision-making at the neuroimaging level, researchers from the University of Ottawa and the University of Pennsylvania found a 24-hour period of sleep deprivation significantly impacted individuals’ decision-making processes by dampening neural responses to the outcomes of their choices.

In other words, people tend to exhibit reduced positive emotions in response to winning outcomes and diminished negative emotions when faced with losses after pulling an all-nighter compared to their well-rested baseline condition.

“Common sense does dictate if people incur sleep loss, sleep disturbance or a sleep disorder that their cognitive function will be impacted, their attention and efficiency will decrease. But there is an emotional impact, too,” says Zhuo Fang, a Data Scientist in the Department of Psychology at the Faculty of Social Sciences.

“If you experience even just one night of sleep deprivation, there will be an impact, even on a neural level. So, we wanted to combine brain imaging and behavior to see that impact,” adds Fang, who is affiliated with uOttawa’s Brain and Mind Research Institute and The Royal.

Consequences for Critical Decision-Making

The study, which evaluated the impact of one night of total sleep deprivation on 56 healthy adults, found:

A single night of total sleep loss significantly decreased the brain activation to win and loss outcomes, suggesting that acute sleep loss can have a dampening effect on neural responses to decision outcomes during risk-taking.Total sleep deprivation had a detrimental effect by disrupting the relationship between neural response and an individual’s risk-taking behavior, which might be related to the altered perception of risk-taking.

While numerous studies have previously illustrated the wide-ranging effects of sleep deprivation on various brain and cognitive functions, including attention processing, memory consolidation, and learning, this study addresses the specific impact of sleep loss on decision-making.

“These results underscore the importance of maintaining adequate sleep and how individuals should refrain from making important decisions when experiencing chronic or acute sleep deprivation,” says Fang, who co-first authored the study with Tianxin Mao of the University of Pennsylvania alongside corresponding author Hengyi Rao.

“In specific professions where decision-makers are required to operate under accumulated sleep loss, specialized training or fatigue risk management might be necessary to enable them to handle such situations effectively.”
