The French philosopher Jean-Luc Nancy's "The Fall of Sleep," in a translation by Charlotte Mandel, is a slender, delirious treatise on what sleep is, what we are doing when we are sleeping, what it means to tomber de sommeil: By falling asleep, I fall inside myself: from my exhaustion, from my boredom, from my exhausted pleasure or from my exhausting pain.
A saturation grid was devised to examine the following concepts in sleep: trouble falling asleep, wake after sleep onset, tossing and turning, waking up due to discomfort, trouble staying asleep, unrested, never fully asleep, time to fall asleep, length of sleep, cyclical sleep (patterns of falling asleep and waking), and feeling unrefreshed (see Table 1).
Caffeine and liquids high in sugar are off the menu, as are fat-laden meals, which take longer to digest and raise body temperature, which in turn slows the process of falling to sleep.
For sleep evangelists and connoisseurs, and even for sleep strivers, the publication this fall from Rizzoli of "Sleep" by Ted Spagna is a watershed event.
Sleep over the last 4 weeks was assessed using 12 questions relating to the time taken to fall asleep, quality of sleep, amount of waking during the night, and the effect of sleep on daytime functioning.
In order to confirm that cage exchange induced sleep disturbances and stress, the animal's behaviour inside the exchanged cage (dirty or clean cage) was recorded for 5.5 h and the sleep-wake cycle, that is, the latency to fall asleep, duration of sleep, and number of sleep episodes, was analysed [ 32].
Most have little difficulty falling asleep because of sleep deficits they sustained during previous nights.
Little or no improvement was seen over time for the ICU group in falling asleep, quality of sleep, and sleep deficit (data not shown).
Items assess difficulty with falling asleep, restlessness of sleep, difficulty getting comfortable, difficulty staying asleep, degree of deep sleep, degree of being rested when waking up for the day, difficulty with beginning the day, and degree of having enough sleep during the previous night.
There are several mechanisms that could be responsible for a lower fall of BP during sleep.
Significant differences were found between groups in depth of sleep, falling asleep, awakenings, falling asleep again after awakening and overall sleep quality (P < 0.05).
