Study type | Observational |
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.

Primary | Comparison of the change in composition of chemical analytes from the breath test | 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 | |
Primary | Change in composition of chemical analytes from the breath test | 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 | |
Primary | Circadian differences in composition of chemical analytes from the breath test | 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). | Study day 1 |
