Sleep in Adolescents - Pilot Study

The goal of this pilot clinical trial is to determine the feasibility and acceptability of increasing time in bed to 10 hours per night in children aged 14-17 years. The main question it aims to answer are: * How much additional sleep short-sleeping-adolescents (\~7h TIB/night) will obtain when asked to increase time-in-bed to 10h/night for seven consecutive nights compared to those who are not asked to increase time-in-bed? * Are adolescents able to comply with study demands: wearing two devices (one on wrist and one on hip) and completing daily sleep diaries and call-ins for seven days? * By acquiring participant feedback, how feasible and acceptable is it to increase time in bed for sleep to 10h/night using a questionnaire and semi-structured interview? * Complete a phone screen * Come to Rutgers Sleep Lab for an orientation to obtain equipment, answer questionnaires and study staff will obtain consent * Wear a wrist device and a hip device for one week to observe sleep and physical activity * If assigned to the 10 hour time-in-bed group, they will follow specific procedures to ensure protocol adherence * Come to the Rutgers Sleep Lab for a follow up to give back equipment and answer questionnaires Researchers will compare the control group to the 10 hour time in bed group to see if it is feasible for 14-17 year olds to be in bed for that long and wear two devices.
