This document summarizes a study on designing an intervention to encourage college students to apply sunscreen daily. The intervention involved sending daily email reminders with weather and UV index information, and a Google form to track sunscreen use. Over 6 students, the average number of days applying sunscreen was 7.1 days, with 1.3 days on average missed. The emails and forms were effective, with an 81% daily success rate on average. Areas for improvement include more automated reminders and tracking to create stronger habits.
