Napping Position Preferences and Perceived Nap Outcomes of the UBC Population Tutinka, Adam; Dumandan, Edgar; Cosman, Dylan; Cheng, Linda; Shan, Samantha Lo Cheuk; Liu, Wendi (Wen Qing)


The present study investigated nap position preferences within the UBC student population and how nap sleep posture can affect perceived mood and alertness-sleepiness outcomes. It was hypothesized that horizontal sleep positions would be the most commonly endorsed preferred napping positions, with improved perceived mood and alertness-sleepiness outcomes. A second hypothesis predicted that lying on one’s back would be the most commonly endorsed napping position, with the best perceived mood and alertness-sleepiness outcomes. Survey data was gathered in-person and online through active recruitment of UBC students. Primary measures included preferred napping position and self-report Likert style questions assessing perceived mood and alertness-sleepiness following less than 30-minute naps. Mood variables consisted of happy-sad, energetic-sluggish, relaxed-tense, and calm-irritable. The outcome measure of alertness-sleepiness was incorporated to reflect the individual’s perceived physiological state post-nap. Descriptive statistics show ‘laying on your back’, ‘laying on your side’, and ‘sitting with your back reclined’ are the most commonly endorsed preferred nap positions for less than 30-minute naps. Results demonstrate no statistically significant difference between preferred napping positions and mood and alertness-sleepiness outcomes. However, a statistically significant difference in mood outcomes between 30-minute or less naps in one’s preferred versus non-preferred position was observed.
