The document summarizes a study on creating a habit of daily sunscreen application through text message reminders. Users received daily reminders at first, then every two days as they consistently applied sunscreen. Overall, users applied sunscreen 71% of the time with reminders. However, without daily reminders at the end of the study, it was unclear if the habit would stick long-term. A longer study is needed to determine the effectiveness of non-daily reminders for habit formation.
