Expecting a stressful day may lower cognitive abilities throughout the day

From Penn State by Katie Bohn

UNIVERSITY PARK, Pa. — There may be some truth to the saying “getting up on the wrong side of the bed,” according to Penn State researchers who say starting your morning by focusing on how stressful your day will be may be harmful to your mindset throughout the day.

The researchers found that when participants woke up feeling like the day ahead would be stressful, their working memory — which helps people learn and retain information even when they’re distracted — was lower later in the day. Anticipating something stressful had a great effect on working memory regardless of actual stressful events.

Jinshil Hyun, a doctoral student in human development and family studies, said the findings suggest that the stress process begins long before a stressful event occurs.

“Humans can think about and anticipate things before they happen, which can help us prepare for and even prevent certain events,” Hyun said. “But this study suggests that this ability can also be harmful to your daily memory function, independent of whether the stressful events actually happen or not.”
