Many university students keep irregular hours and spend most of the day indoors, where light is far dimmer than daylight. This study asks whether adding a short, bright morning light session can help.\n\nEach participant takes part for two weeks. For one week they use a bright light box for 30 minutes each morning, shortly after waking; for the other week they keep their usual lighting. The order of the two weeks is decided at random, and each person serves as their own comparison.\n\nThroughout both weeks, sleep is tracked with a wrist-worn Fitbit and a short daily diary. Participants also rate their sleepiness and mood, complete brief computer-based attention and memory tasks, and take part in a short interview at the end about their experience.\n\nThe study compares the bright-light week with the usual-light week to see whether morning bright light improves sleep regularity and efficiency, reduces daytime sleepiness, lifts mood, or affects thinking performance. The trial is being conducted in waves; a first wave has completed and a second wave is planned, pending additional funding.",[28,29,30,31,32,33],"Sleep","Circadian Rhythm","Daytime Sleepiness","Mood","Cognition","Healthy Volunteers",[35,36,37,38,39,40,41,42,43,44],"Bright light therapy","Melanopic illuminance","Morning light exposure","Sleep regularity","Sleep efficiency","Daytime alertness","Crossover trial","University students","Wearable sleep tracking","Karolinska Sleepiness Scale","RECRUITING","2026-06-29",{"date":48,"type":49},"2026-07-06","ACTUAL",{"date":51,"type":49},"2024-05-01",{"date":53,"type":22},"2028-06-30",{"name":55,"class":56},"The Hong Kong Polytechnic University","OTHER",1,{"id":59,"slug":60,"hasResults":11,"nctId":61,"briefTitle":62,"officialTitle":63,"acronym":64,"eligibilityCriteria":65,"healthyVolunteers":17,"sex":18,"minAge":66,"maxAge":67,"enrollmentInfo":68,"targetDuration":4,"studyType":23,"phases":70,"briefSummary":71,"conditions":72,"keywords":78,"overallStatus":45,"whyStopped":4,"lastUpdateSubmitDate":82,"lastUpdatePostDateStruct":83,"startDateStruct":85,"completionDateStruct":87,"leadSponsor":89,"locationsCount":57},"100539611","promoting-teenage-sleep-for-improved-mental-health-and-school-performance-100539611","NCT06306092","Promoting Teenage Sleep for Improved Mental Health and School Performance","Promoting Teenage Sleep - for Better Mental Health and School Performance","TeenSleep","Inclusion Criteria:\n\nStudents in Swedish high schools and upper secondary schools.\n\nExclusion Criteria:\n\n\\-","13 Years","19 Years",{"count":69,"type":22},3000,[25],"The overall aim of this project is to evaluate the effectiveness of two school-based programs that have the potential to promote adolescent sleep and prevent future depressive symptoms.
