Sleep reactivity and night-shift sleep problems
Sleep reactivity as a novel mechanism in Shift Work Disorder
This project looks at whether a person’s tendency for sleep to be easily disturbed (sleep reactivity) helps explain excessive sleepiness and insomnia in night-shift workers.

What this research studies
From the patient’s perspective, researchers will work with people who regularly do night shifts and have trouble sleeping or staying alert. You may be asked about your sleep history, complete questionnaires about how easily your sleep is disturbed, and wear sleep-monitoring devices or attend clinic visits for sleep measurements. The team will compare sleep timing, circadian measures, and sleep reactivity to see what drives shift work disorder. Findings aim to point toward treatments that target the root causes rather than only masking symptoms.
Who could benefit from this research
Good fit: Ideal candidates are adults who regularly work night shifts and report excessive sleepiness or insomnia consistent with shift work disorder.
Not a fit: People who do not work night shifts or whose sleep problems are caused primarily by other medical conditions (for example untreated sleep apnea) may not benefit directly from this work.
Why it matters
Potential benefit: If successful, this could lead to treatments that address the underlying causes of shift work disorder and reduce sleepiness, insomnia, and safety risks for night-shift workers.
How similar studies have performed: Most prior approaches have focused on symptom management (stimulants or hypnotics) rather than mechanisms, so targeting sleep reactivity is a relatively new and untested direction.
