Summary

This study looks at whether a person's tendency to have trouble sleeping when stressed (called sleep reactivity) is a main cause of Shift Work Disorder. Researchers will reduce the mismatch between workers' body clocks and their nightshift schedule, then see if those with high sleep reactivity still have symptoms. They will test if cognitive behavioral therapy (CBT) can help these workers sleep better. The study involves 150 nightshift workers diagnosed with Shift Work Disorder.
