According to the findings of business professors at the University of Washington, the University of Arizona and the University of North Carolina, published last month in the Journal of Applied Psychology, coffee can help sleep-deprived employees resist the urge to go along with unethical behavior.
Study participants stayed up all night and then chewed a piece of regular gum or gum laced with 200 mg of caffeine, the equivalent to two cups of coffee. One of the researchers told Fortune that participants were then encouraged "to go along with a lie in order to earn some extra money. We tried to replicate a situation where a boss or a peer was pressuring them to cut ethical corners at work."
The results? Those who chewed caffeinated gum were less likely go along with deception than the group who chewed regular gum.
Their findings built upon previous researchby two of the authors who'd found that lack of sleep can make workers more susceptible to social influence, less able to regulate their emotions and more likely to make or go along with unethical choices in the workplace.
In a press release, David Welsh, an organizational behavior professor at the University of Washington, said “When you’re sleep deprived at work, it’s much easier to simply go along with unethical suggestions from your boss because resistance takes effort and you’re already worn down. However, we found that caffeine can give sleep-deprived individuals the extra energy needed to resist unethical behavior.”
The researchers also have a few other non-stimulant-based suggestions for curbing bad behavior at work:
Reduce long hours with scheduling, overtime restrictions and frequent breaks
Avoid scheduling tasks that require a great deal of self-control when looming deadlines make long hours unavoidable
Provide workplace napping and sleep awareness training
