Study Summary

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" 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 heart tracker on their wrist and a blood pressure cuff on their arm for three days during the second and third week, for a total of six days.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
