During a 1.5-week inpatient laboratory protocol, participants will undergo one of two parallel sleep conditions during either the follicular or luteal phase of the menstrual cycle (4 study arms total). Subjects will be randomly assigned to each study arm. During their time in the laboratory, biological samples (e.g., blood) will be collected for assessment of sex steroid hormones and other analyses. Sleep quantity and quality will be monitored and responses on neurobehavioral tests and surveys will be monitored for differences across conditions.
This study is designed to assess how healthy premenopausal women respond to different patterns of sleep loss at different times in the menstrual cycle.
