As the study’s lead author, Leah Sheppard Ph.D., explains in A new version“When women get a good night’s sleep and their mood improves, they are more likely to be directed in their daily intentions toward achieving status and responsibility at work. If their sleep is poor and their mood lowers, we have seen that they are less oriented toward those goals.”
Going forward, the researchers add, discovering the mechanisms underlying gender differences in the effect of sleep on motivation is an important consideration. For now, we can only speculate about why women are affected more, as the researchers suggested it could be a combination of sex differences in emotion regulation and societal expectations.
But if there’s anything to be gathered from these findings, it’s that working women can expect their motivation to suffer when their sleep hurts, too. But the good news is that the opposite is also true – and good sleep can mean more stimulation.
