About

This study is designed to assess how healthy premenopausal women respond to different patterns of sleep loss at different times in the menstrual cycle.

Full description

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.

100 participants in 4 patient groups

Chronic variable sleep deficiency - follicular phase
Experimental group
Description:
This will be the first of four arms of controlled sleep manipulation. Participants randomized to this arm will be studied on a chronic variable sleep deficiency schedule during the follicular phase of their menstrual cycle. The exact sleep schedule is not provided in order to keep participants blinded to sleep conditions.
Treatment:
Behavioral: Controlled sleep
Chronic variable sleep deficiency - luteal phase
Experimental group
Description:
This will be the second of four arms of controlled sleep manipulation. Participants randomized to this arm will be studied on a chronic variable sleep deficiency schedule during the luteal phase of their menstrual cycle. The exact sleep schedule is not provided in order to keep participants blinded to sleep conditions.
Treatment:
Behavioral: Controlled sleep
Control sleep - follicular phase
Experimental group
Description:
This will be the third of four arms of controlled sleep manipulation. Participants randomized to this arm will be studied on a control sleep schedule during the follicular phase of their menstrual cycle. The exact sleep schedule is not provided in order to keep participants blinded to sleep conditions.
Treatment:
Behavioral: Controlled sleep
Control sleep - luteal phase
Experimental group
Description:
This will be the fourth of four arms of controlled sleep manipulation. Participants randomized to this arm will be studied on a control sleep schedule during the luteal phase of their menstrual cycle. The exact sleep schedule is not provided in order to keep participants blinded to sleep conditions.
Treatment:
Behavioral: Controlled sleep
