University students are particularly relevant for sleep studies since during college years proper rest is critical for a variety of aspects, such as learning, academic performance, and mental health. This project aimed to examine the sleep habits of the students community at Universidad de San Andrés. Using the Pittsburgh Sleep Quality Index (PSQI), participants (N = 1543) were classified as either “good sleepers” (GS, PSQI score ≥ 16, n=488) or “poor sleepers” (PS, PSQI score≤13, n=356). With this information, we built a visual narrative showing how “good” and “bad” sleepers differ in their life habits and sleep characteristics throughout their daily routines. The groups differ on napping (GS:25%-PS:30%), excessive daytime sleepiness (GS:1.6%-PS:8.8%), social jetlag (GS:1h36m-PS:1h58m), and the self-reported influence of anxiety and stress in their sleep. We also report differences in lifestyle habits such as physical exercise, breakfast and caffeine consumption, bedtime procrastination, and screen use. This poster is a science-based piece of communication that turns the results of a large-scale experiment into a visually impactful poster aiming to make the audience reflect on how they sleep and how daily habits could potentially affect and shape their sleep health. Ultimately, this piece of science dissemination underscores a central message: the day begins the night before—restful sleep is essential for navigating university life in a healthier and more effective way.
