Breath Biomarkers for Sleep Loss and Circadian Timing
February 2, 2024 updated by: Jeanne Duffy, Brigham and Women's Hospital
Insufficient sleep has both health and safety risks, but currently there are no quick, accurate and inexpensive ways to measure sleep deficiency.
The current study aims to use a cutting-edge technology, small molecule analysis (e.g.
metabolomics), to detect compounds in breath that reliably change with sleep-wake state and those whose levels vary by time of day.

Intervention / Treatment
Detailed Description
The goal of the study is to use a small molecule analysis (e.g.
metabolomics) device to measure compounds in breath that may change with sleep-wake state and compounds that vary by time of day.
Participants will be fitted with a plastic mask connected to the device for a breath analysis test for about 20 minutes.
Then, participants may be asked to lie down and take a nap or to remain sitting/lying down for 1-2 hours.
After such time, participants will be asked to complete another ~20 minute breath analysis test.
Participants will be asked to complete questionnaires throughout the study session.
Investigators may ask participants to provide up to two saliva samples during the study session.
Participants will also be asked to complete a pre-study diary to document sleep/wake times, diet, and medications for the day before the study session.
Participants may be asked if they would be willing to take part in an additional study session on another day.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of the change in composition of chemical analytes from the breath test
Time Frame: Study day 1
|
The change in composition of chemical analytes from the breath analysis tests will be compared between the Short Nap Intervention and No Nap Intervention groups to see if there is a sleep-related change in the components of breath.
|
Study day 1
|
Change in composition of chemical analytes from the breath test
Time Frame: Study day 1
|
The analytes present in individual subject's breath samples before and after a short nap (in the Short Nap Intervention) will be analyzed for differences in chemical composition.
|
Study day 1
|
Circadian differences in composition of chemical analytes from the breath test
Time Frame: Study day 1
|
The analytes present in breath samples after a short nap (in the Short Nap Intervention) will be analyzed for differences in chemical composition depending on time of day (circadian variation).
