Sleep Fragmentation, Sleep Deprivation, or Both

Sleep fragmentation, sleep deprivation, or both.

I applaud the efforts of Schwartz and Moxley to explore ways to achieve greater understanding of the role of arousals in producing daytime impairment.1 This area of research has great clinical relevance, but has been largely neglected in recent years. Schwartz and Moxley distinguish short arousals (3-15 secs) from long arousals (15-60 secs) and wake events (>60 secs). They found that long arous...

The Functional Impact of Sleep Deprivation, Sleep Restriction, and Sleep Fragmentation

M.T. Bianchi (ed.), Sleep Deprivation and Disease: Effects on the Body, Brain and Behavior, DOI 10.1007/978-1-4614-9087-6_2, © Springer Science+Business Media New York 2014 Paradigms of sleep deprivation, sleep restriction, and sleep fragmentation have been utilized to answer fundamental questions about sleep, including how much sleep adults need and the defi cits and recuperation associated wi...

Energy expenditure during sleep, sleep deprivation and sleep following sleep deprivation in adult humans

Sleep has been proposed to be a physiological adaptation to conserve energy, but little research has examined this proposed function of sleep in humans. We quantified effects of sleep, sleep deprivation and recovery sleep on whole-body total daily energy expenditure (EE) and on EE during the habitual day and nighttime. We also determined effects of sleep stage during baseline and recovery sleep...

Sleep deprivation

Sleep deprivation in the rat: III. Total sleep deprivation.

Ten rats were subjected to total sleep deprivation (TSD) by the disk apparatus. All TSD rats died or were sacrificed when death seemed imminent within 11-32 days. No anatomical cause of death was identified. All TSD rats showed a debilitated appearance, lesions on their tails and paws, and weight loss in spite of increased food intake. Their yoked control (TSC) rats remained healthy. Since dehy...
