简要总结
The Phone Sleep 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 and participants will be asked to wear a sleep-monitoring "actiwatch", a heart tracker, and an activity monitor, as well as to provide screenshots of participants' smartphone's screen time app for three weeks. Participants will also be asked to wear a blood pressure cuff on their arm for three days during each week, for a total of nine days.
