Brief Summary
The purpose of this study is to examine the impact that sleep duration has on blood pressure (BP) levels during sleep. The investigator will examine the effect of an 8-week sleep hygiene/extension intervention vs. control on sleep BP.

Outcome Measures
Primary Outcomes (2)
Mean Sleep Systolic Blood Pressure (BP) at Baseline and 8 Weeks
Mean of valid BP readings during the sleep period on 24-hour ambulatory blood pressure monitor will be calculated to obtain mean sleep systolic BP (mmHg) at baseline and 8 weeks.
Baseline, 8 weeks
Mean Sleep Diastolic Blood Pressure (BP) at Baseline and 8 Weeks
Mean of valid BP readings during the sleep period on 24-hour ambulatory blood pressure monitor will be calculated to obtain mean sleep diastolic BP (mmHg) at baseline and 8 weeks.
Baseline, 8 weeks
Secondary Outcomes (5)

Sleep Hygiene/Extension Intervention
EXPERIMENTALParticipants with short sleep duration will receive a 60-minute educational session on sleep hygiene/extension. Over an 8-week period, participants will receive weekly phone or Zoom video calls from the Educational Research Coordinator to review additional materials including handouts and/or complete questionnaires about sleep. Participants will undergo sleep tracking/monitoring during the 8-week period, and repeat BP/heart rate monitoring for 24 hours after the 8-week period.
Control Condition
ACTIVE COMPARATORParticipants with short sleep duration will receive a 60-minute educational session on sleep physiology. Over an 8-week period, participants will receive weekly phone or Zoom video calls from the Educational Research Coordinator to review additional materials including handouts. Participants will undergo sleep tracking/monitoring during the 8-week period, and repeat BP/heart rate monitoring for 24 hours after the 8-week period.
Interventions
The 60-minute sleep hygiene/extension educational session include the following: This session will consist of questionnaires, handouts, videos, and a discussion. Topic examples include information on establishing a comfortable sleep environment, including strategies on how to extend sleep duration by a maximum of 1 hour over the duration of the 8-week trial for an average of 7.5 minutes per week, not to exceed 15 minutes per week. Participants will also receive educational brochures and a sleep diary.
The 60-minute educational session will address sleep physiology but not sleep hygiene. This session will consist of questionnaires, handouts, videos, and a discussion. Participants will receive an educational brochure.

- Masking Details
- Participants will be randomized in a 1:1 ratio to each arm by a computer-generated random allocation sequence. All study investigators and outcome assessors will be blinded to group assignment and will not have access to the randomization sequence. The Educational Research Coordinator who will deliver the educational sessions will be unblinded to treatment arm but will not be involved in collecting study measures or data analyses.
