Night shift work is associated with sleep problems and multiple other negative health effects. Prolonged wakefulness induces deficits in brain functions, which affects alertness, performance and mood. My PhD-project is a translational project and involves simulating night-shift work in both rats and humans. I aim to investigate how night-shift work affects waking function and cognitive performance during work, and subsequent sleep. I will also investigate how different light interventions during simulated night-shifts will affect the brains' processing capasity and how it may impact daytime sleep.
