“Biomarkers of Increased Free Living Sleep Time”
This protocol will increase sleep duration in participants who maintain less than 6 hours sleep per night, to target the recommended 7 hours of sleep per night. The focus of this study is determine how increasing nightly sleep duration in these individuals who maintain less than 6 hours sleep per night changes their plasma metabolome and insulin sensitivity. The primary outcome will examine changes in branched-chain amino acids and the secondary outcome will examine changes in insulin sensitivity. The investigators will also determine if changes in plasma metabolites can be used as a biomarker to discriminate between adequate versus insufficient sleep.
Behavioral - Increased sleep duration
Participants will increase their nightly time in bed by 2 hours per night for 4 weeks to target the recommended 7 hours of sleep per night.
