Experimental: Sleep limited
Participants will be asked to limit their sleep
|
Other: Urine sample
Collection of 36-84 urine samples over a 14 consecutive day period. Other: Sleep restriction Participants will be asked to limit their sleep to 4 hours within a 24-hour period for 2 days in a row. |
Experimental: No sleep limitation
Participants will be asked to get their normal amount of sleep.

Other: Urine sample

- Change in inflammation [ Time Frame: Baseline to day 14 ]Changes in inflammation will be measured by hs-CRP via short-term sleep restriction.
- Correlate biohealth data with concentrations of urine metabolites [ Time Frame: Daily for 14 days ]To explore connections between urine metabolite concentrations and others measures of health and lifestyle, biometric data will be collected using a FitBit watch (sleep and exercise), nutritional data (food logs) and a questionnaire (tobacco use). Urine will be analyzed using mass spectrometry to isolate metabolites. The metabolites will then be cross-referenced against databases of known metabolites in order to identify them and their disease associations.
