A new study from the Surrey Sleep Research Centre at the University of Surrey, published today in the journal PNAS (Proceedings of the National Academy of Sciences) has found that shifted sleep-wake cycles affect men and women's brain function differently.

The results revealed that in both men and women self-reported assessments were more sensitive to the effects of time awake and circadian clock than the many objective measures of performance. However, crucially, the circadian effect on performance was significantly stronger in women than in men such that women were more cognitively impaired during the early morning hours, which in the real world typically coincides with the end of a night shift.
