WORK PERFORMANCE MAY BE AFFECTED BY EATING LATE NIGHT SNACKS

Time to quit eating at night? According to the findings of a new study, unhealthy eating behaviours at night can make people less helpful and more withdrawn the next day at work.

The findings of the study were published in the Journal of Applied Psychology. “For the first time, we have shown that healthy eating immediately affects our workplace behaviours and performance,” said Seonghee “Sophia” Cho, corresponding author of the study and an assistant professor of psychology at North Carolina State University.

Cho added, “It is relatively well established that other health-related behaviours, such as sleep and exercise, affect our work. But nobody had looked at the short-term effects of unhealthy eating.”

Fundamentally, the researchers had two questions: Does unhealthy eating behaviour affect you at work the next day? And, if so, why?

For the study, researchers had 97 full-time employees in the United States answer a series of questions three times a day for 10 consecutive workdays. Before work on each day, study participants answered questions related to their physical and emotional well-being.

At the end of each workday, participants answered questions about what they did at work. In the evening, before bed, participants answered questions about their eating and drinking behaviours after work.

In the context of the study, researchers defined “unhealthy eating” as instances when study participants felt they’d eaten too much junk food; when participants felt they’d had too much to eat or drink; or when participants reporting having too many late-night snacks. The researchers found that, when people engaged in unhealthy eating behaviours, they were more likely to report having physical problems the next morning. Problems included headaches, stomachaches and diarrhea.

In addition, when people reported unhealthy eating behaviours, they were also more likely to report emotional strains the next morning – such as feeling guilty or ashamed about their diet choices. Those physical and emotional strains associated with unhealthy eating were, in turn, related to changes in how people behaved at work throughout the day.

Essentially, when people reported physical or emotional strains associated with unhealthy eating, they were also more likely to report declines in “helping behaviour” and increases in “withdrawal behaviour.”

Helping behaviour at work refers to helping colleagues and going the extra mile when you don’t have to, such as assisting a co-worker with a task that is not your responsibility. Withdrawal behaviour refers to avoiding work-related situations, even though you’re at your workplace.

The researchers also found that people who were emotionally stable suffered fewer adverse effects from unhealthy eating. Not only were emotionally stable people less likely to have physical or emotional strains after unhealthy eating, their workplace behaviours were also less likely to change even when they reported physical or emotional strains.
