Study Details

Brief summary:

The purpose of this study is to examine the effect that melatonin lotion has on sleep quality, the nervous system, and mental health. Melatonin is a hormone secreted by the brain that regulates sleep and might improve depression and anxiety symptoms. The goal is to determine whether melatonin in lotion form is an effective treatment for young adults with inadequate sleep and might improve mental health. Participants will fill out surveys, wear an actigraph (a wrist-worn device that measures sleep), wear a heart rate monitor (a strap worn around one's chest), and provide nightly saliva samples during treatment weeks. In one of the two treatment weeks, participants will receive a lotion that contains melatonin. During the other week they will receive a control treatment that will be lotion with no melatonin, and there will be a week in between with no treatment at all.

Interventions and Outcome Measures

Arms

experimental: Melatonin lotion first

Participants will be randomized to one week of treatment with melatonin lotion, followed by a week washout, then one week of treatment with placebo lotion

experimental: Placebo lotion first

Participants will be randomized to one week of treatment with placebo lotion, followed by a week washout, then one week of treatment with melatonin lotion

Interventions

Melatonin lotion

3 g lotion applied one hour before bedtime

Placebo lotion
