Evaluating the consequences of mistimed light-emitting device use on cardiac activity and sleep health

The study is being done to find out whether wearing blue light-blocking glasses in the evening improves subsequent sleep. This is a 21-day study where participants will be asked to wear a sleep-monitoring “actiwatch”, an activity monitor, and a heart tracker, as well as to provide screenshots of their smartphone’s screen time app for three weeks. Participants will also be given the option to wear a blood pressure cuff on their arm for three days during the second half of each week, for a total of nine days.

Study participants will be asked to wear small devices on their wrist, hip, and shirt collar, and provide screenshots of their smartphone screen time app for three weeks. During the second and third weeks, participants will be asked to wear a pair of blue light-blocking glasses. Halfway through each week, participants will also be asked to wear a blood pressure monitor for 3 days/nights. There will be a total of seven in-person visits. At the first visit we will explain the study, ask interested participants to sign a consent form, collect information, and distribute study materials and devices. During all subsequent visits, participants will answer questionnaires and be provided additional study materials and devices.
