Abstract
The high prevalence of poor sleep quality among young adults in Malaysia is alarming, as it is associated with physical inactivity and mood disturbance, which can negatively impact achievements and daily functioning. This study examined the within-subject temporal association of physical activity and subsequent sleep quality, focusing on total sleep time (TST), sleep efficiency (SE) and sleep onset latency (SOL). Using ecological momentary assessment, 112 participants (mean age = 21.91 years, SD = 1.56; female = 81.2%) tracked their physical activity, mood and sleep for a week via actigraphy, mood and sleep diaries. Results indicated that physical activity significantly predicted subsequent night TST, SE, SOL and sleep quality. Mood disturbances also significantly predicted TST, SE and sleep quality, while overall mood was a significant predictor of TST and sleep quality. These findings highlighted the importance of physical activity and mood regulation in promoting better sleep quality.
