Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to investigate the relationship between reminder messages sent via text and compliance with a daily morning light intervention designed to advance the circadian clock. Twenty healthy adults will be recruited to participate in a randomized, cross-over study where daily messages are, or are not, provided to remind participants to carry out the intervention.
