Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators will track students sleep patterns before and after a sleep intervention where they are given a packet of sleep tips and encouraged to improve their sleep hygiene.
Outcomes include stress levels, academic/athletic performance, and sleep cycle data from the sleep tracking watch.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To determine the effect of sleep extension on stress levels, cognitive function, and fitness in teenage girls.
B. HYPOTHESIS / SPECIFIC AIMS
If teenagers attain the recommended amount of sleep (9-9.5 hours per night), they will feel less stress and have better athletic and academic performance.
Primary Objective:
• The investigators will evaluate stress with a validated questionnaire before and after sleep extension (increased total sleep time per night).
Secondary Objectives:
* The investigators will evaluate physical fitness and endurance with standardized testing before and after sleep extension.
* The investigators will measure several sleep variables (total sleep time, sleep efficiency, sleep onset latency, sleep-wake cycle pattern, sleepiness) before and after sleep extension.
* The investigators will evaluate the association between academic performance (Grade Point Average (GPA) and average total sleep time per night.
Intervention:
Sleep extension: Increasing nightly total sleep time (goal of 9-9.5 hours per night) by improving sleep hygiene, daily exercise, etc.
In a prospective cohort study, up to 40 otherwise healthy teenage girls age 14-18 years at DSHA High School will be approached for consent to participate in the study. Upon consent they will complete the Insomnia Severity Index (ISI), Epworth Sleepiness Scale for Children and Adolescents (ESS-ChAD) and Perceived Stress Scale (PSS) questionnaires and will be issued an actigraphy watch to monitor their sleep-wake cycles daily at home for 2 weeks. They will also keep a sleep diary during the study period.
After the 2 weeks of actigraphy, subjects will have the data from the actigraphy watch downloaded and submit their sleep diary. They will be given sleep hygiene recommendations to try to attain 9-9.5 hours of sleep per night (sleep extension), if not already sleeping this amount. They will then be given a different actigraphy watch to wear and another sleep diary to log their total sleep time for 4 more weeks.
After the 4 weeks, the actigraphy watch will be returned, the actigraphy data will be downloaded and the sleep diary data will be collected. Subjects will complete the ESS-ChAD and PSS upon conclusion of the study. Subjects will be offered a report of their sleep and activity data after completing the sleep extension period. If there is a gap of more than 4 weeks between actigraphy use and the second fitness test, the investigators will ask participants to complete another 1-week sleep diary prior to testing. All study activities except downloading the actigraphy watch data will occur at Divine Savior Holy Angels High School (DSHA).
