New research shows that pulling an all-nighter hurts memory and wrecks productivity, particularly if you’re female.
Burning the midnight oil can burn you at work the next day – especially if you’re female.
Studies have shown that sleep deprivation hurts employee performance, which costs the U.S. economy $411 billion in lost productivity each year. But new research from Sweden’s Uppsala University now finds that pulling an all-nighter to make a work deadline or prep for an exam messes with women’s brains even worse than men’s.
The 12 young men and 12 young women in the study were each tasked with memorizing an 8-digit sequence the morning after a full night of sleep, and another 8-digit sequence the morning after they were up all night. And while the young men’s working memory remained the same whether or not they got enough shut-eye, the young women remembered fewer digits after their all-nighters. They were also unaware that their memory performance had taken a hit.
