Daytime sleepiness, or difficulty in maintaining a desired level of wakefulness, is frequently viewed by the general population as a common experience and predictable consequence of insufficient sleep. However, daytime sleepiness can have a serious impact on an individual's health, safety, and quality of life. Despite the fact that population-based studies have found that 1 in 5 adults suffers from daytime sleepiness, there is a lack of consistency in how daytime sleepiness is defined, measured, and interpreted, which may affect the medical management of the disorder. For example, many measures of sleepiness based on sleep propensity and falling asleep tend to overlook patients with insomnia and sleepiness. Sleep scales that contain sensitive and specific questions are needed to measure fatigue and perceptions of sleepiness.
白天嗜睡，即难以维持理想的清醒程度，在普通大众看来通常是一种常见现象，也是睡眠不足可预见的后果。然而，白天嗜睡会对个人的健康、安全和生活质量产生严重影响。尽管基于人群的研究发现五分之一的成年人患有白天嗜睡症，但在白天嗜睡的定义、测量和解释方面缺乏一致性，这可能会影响该病症的医疗管理。例如，许多基于睡眠倾向和入睡情况的嗜睡测量方法往往会忽略患有失眠和嗜睡症的患者。需要包含敏感且具体问题的睡眠量表来测量疲劳和嗜睡感。
