About this study
This research project consists of a three part study with five embedded sub studies. The first study phase identifies "body rhythms" of sleepiness/wakefulness and of melatonin levels for each subject (including sub-study 1). The second study phase identifies the optimum dose and timing of melatonin for regulating each individual's 24-hour sleep/waking cycle (including sub-study 2). The third study phase introduces a new independent variable, light (including sub-studies 3 and 4). Sub-study 5 is an optional longitudinal study.
Sub-study 1 looks at how keeping a regular sleep schedule affects the body's natural rhythm. Sub-study 2 looks at how individuals metabolize melatonin. Sub-study 3 tests how individuals' endogenous melatonin production responds to bright outdoor light and Sub-study 4 tests a previous finding that artificial bright light exposed daily behind the knee can regulate the body clock. Sub-study 5 is an optional longitudinal study, an extension of the first study stage, for subjects whose rhythms are not clearly free-running.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MelatoninDrug
Melatonin will be administered under FDA IND #26,318, doses between 0.025 mg and 20 mg.
Regular Sleep ScheduleBehavioural
Subjects will maintain a regular sleep schedule of their choosing.
LightBehavioural
Subjects will be exposed to light.
| Study group | Role | What they receive |
|---|---|---|
| Baseline | No intervention | Not described |
| Melatonin | Experimental | Subjects will be administered melatonin. Receives: Drug: Melatonin |
| Light | Experimental | Not described Receives: Behavioral: Light |
| Regular Sleep Schedule | Experimental | Not described Receives: Behavioral: Regular Sleep Schedule |
| Longitudinal Monitoring | No intervention | Optional longitudinal study, an extension of the first study stage, for subjects whose rhythms are not clearly free-running. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Treatment Effects on Circadian Phase Will be Assessed During Each Trial by Measuring the Timing of Endogenous Melatonin Secretion.
Measured: 1 year
Secondary outcomes (1)
Treatment Effects on Sleep and Alertness Will be Assessed by Daily Diaries and Daily Wrist Actigraphic Monitoring. Subjective Benefits Will be Assessed With Daily Ratings of Alertness and Vigor.
Measured: 1 year
