Clinical Trial Summary

The purpose of this research study is to investigate the relationship between light and circadian rhythms. Twenty healthy older adults will be recruited to participate in a randomized, cross-over study, where an active lighting intervention designed to maintain entrainment and a control intervention designed not to entrain will be tested.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Saliva samples for melatonin levels	Serial saliva samples will be collected to calculate dim light melatonin onset.	Baseline and 2-weeks post-intervention
Secondary	Light exposure using the Speck	The Speck light meter will be used to collect overall light exposure.The Speck light meter uses a photosensor to measure the amount of light study participants are exposed to each day.	worn all 12 study weeks
Secondary	Sleep time using actigraphy	Sleep time will be calculated from the actigraph. The wrist actigraph measures activity during the day and how well you sleep at night. The actigraph software will calculate the amount of time spent in bed sleeping.	worn all 12 study weeks
