- The impact of lighting conditions on waking function in night workers. A translational project

This translational research project aims to increase the knowledge on how lighting conditions in the physical work environment during night shift work influence the brains’ waking function and subsequent sleep. The subgoals of the project are

  • to investigate the effects of different lighting conditions on alertness and cognitive performance
  • to investigate the effects of different lighting conditions on total sleep time and sleep quality after ended night shift
  • to identify possible changes in the brains’ plasticity underlying any neurobehavioral improvements.
