Studies in healthy young adults revealed that periodic arousals during the night result in increasing sleepiness as a function of the interval of time between arousals. When arousals are frequent, deficits similar to those seen after total sleep deprivation have been found. Observed decrements appear to be specifically related to EEG arousals and do not require complete awakening. In patients with fragmenting sleep disorders such as periodic leg movements and central sleep apnea, improved nocturnal sleep is related to increased alertness and daytime performance.
对健康年轻成年人的研究表明，夜间的周期性觉醒会导致困倦感增加，且这种困倦感是觉醒之间时间间隔的函数。当觉醒频繁时，已发现存在类似于完全睡眠剥夺后出现的缺陷。观察到的能力下降似乎与脑电图觉醒特别相关，并不需要完全清醒。在患有睡眠碎片化障碍（如周期性腿部运动和中枢性睡眠呼吸暂停）的患者中，夜间睡眠改善与警觉性提高和白天表现改善有关。
