Effects of sleep fragmentation
on glucose metabolism in normal subjects.
(episodes of waking that disrupt sleep) was also unrelated to cold susceptibility.
In studies that use sleep fragmentation
it is necessary to carefully define the changes provoked in the architecture of sleep, that is, which sleep/dream stage is specifically targeted (for instance, SWS or REM sleep, or whether the researchers plan random fragmentation, such as in the case of sleep disorder).
There was a correlation between the number of subjectively reported nighttime hot flashes with increased sleep fragmentation
as measured by PSG.
Chronic sleep restriction and sleep fragmentation
is one adverse outcome attributed to RLS and PLMs.
16) It is natural to believe that Hypoxemia is responsible for sleep fragmentation
in COPD and this Hypothesis is supported by experimental studies.
In a previous study, they showed that children with AD have longer sleep-onset latency, more sleep fragmentation
, less REM sleep, and reduced sleep efficiency than healthy controls; and that these sleep disturbances are associated with scratching movements, more severe dermatitis, and decreased melatonin secretion.
Sleep loss perse, including sleep deprivation, sleep restriction, or sleep fragmentation
(see Table 1 for a full differentiation between the concepts), generates a pathogen-independent low-grade inflammatory status.
Researchers add they did not find significant differences in negative mood between the two groups on any of the three days, which suggests that sleep fragmentation
is especially detrimental to positive mood.
Increase in diurnal somnolence is common due to sleep fragmentation
OSA is a common sleep disorder characterized by recurring collapse of the upper airway during sleep, resulting in sleep fragmentation
and oxygen desaturation.
The researchers also speculate on the important role played by sleep apnea in perpetuating insomnia; sleep breathing episodes cause sleep fragmentation
and overall disruption to the sleep cycle.
For some women, sleep fragmentation
, especially sleep apnea, can be profound.
Patients can mistakenly misperceive sleep or wakefulness due to dissociation and sleep fragmentation
Primary features of OSA include sleep fragmentation
accompanied by nocturnal hypoxemia and hypercapnia, with resulting excessive daytime sleepiness, mood problems, and poor neurocognitive performance (Table 1).
