- Primary Outcome Measures
Name Time Method Saliva samples for melatonin levels Baseline and 2-weeks post-intervention Serial saliva samples will be collected to calculate dim light melatonin onset.
- Secondary Outcome Measures
Name Time Method Light exposure using the Speck worn all 12 study weeks 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.
Sleep time using actigraphy worn all 12 study weeks 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.
