The document describes a study that compared characteristics of patients with obstructive sleep apnea (OSA) who were classified as sleepy versus non-sleepy. Sleepy patients had shorter total sleep time, less nocturnal sleep, more time awake during sleep, and reported poorer sleep quality and greater functional impairment. The results suggest behavioral factors leading to shorter and poorer sleep may contribute to greater subjective sleepiness and symptoms among OSA patients.
