Sleep disorders and sleep deficiency are important causes of adverse health effects and increased mortality in the United States and worldwide. Sleep deficiency can also result in myriad adverse behavioral consequences, including profound sleepiness, cognitive slowing, automatic behavior, attentional failures and performance degradation, errors, and accidents. It is important to recognize that sleepiness and sleep deficiency are not synonymous.
睡眠障碍和睡眠不足是美国和全球范围内不良健康影响和死亡率增加的重要原因。睡眠不足还会导致无数不良行为后果，包括极度困倦、认知迟钝、自动行为、注意力不集中和表现下降、失误和事故。重要的是要认识到困倦和睡眠不足并不完全等同。
