TLDR
Evidence is presented that insomnia with objective short sleep duration is the most biologically severe phenotype of the disorder, as it is associated with cognitive-emotional and cortical arousal, activation of both limbs of the stress system, and a higher risk for hypertension, impaired heart rate variability, diabetes, neurocognitive impairment, and mortality.

Sleep Disturbance, Sleep Duration, and Inflammation: A Systematic Review and Meta-Analysis of Cohort Studies and Experimental Sleep Deprivation

TL;DR: Global evidence linking sleep disturbance, sleep duration, and inflammation in adult humans is assessed and sleep disturbance and long sleep duration are associated with increases in markers of systemic inflammation.

Why Sleep Is Important for Health: A Psychoneuroimmunology Perspective

TL;DR: The impact of sleep on adaptive and innate immunity, with consideration of the dynamics of sleep disturbance, sleep restriction, and insomnia on antiviral immune responses with consequences for vaccine responses and infectious disease risk and proinflammatoryimmune responses with implications for cardiovascular disease, cancer, and depression is highlighted.

The Sleep-Immune Crosstalk in Health and Disease

TL;DR: The induction of a hormonal constellation that supports immune functions is one likely mechanism underlying the immune-supporting effects of sleep, and sleep appears to promote inflammatory homeostasis through effects on several inflammatory mediators, such as cytokines.

Slow-wave sleep and waking cognitive performance II: Findings among middle-aged adults with and without insomnia complaints

TL;DR: Results support the prediction that the presence of sleep pathology alters the SWS-performance relationship observed and suggest that the specific performance demands of the task in question as well as physiological parameters other than SWS may determine performance as well.

Subjective and Objective Performance in Patients with Persistent Insomnia

TL;DR: In this paper, the authors compared 20 normal sleepers and 20 persistent insomnia patients on a computerized test battery with four tasks: reaction time, two memory tasks, and finger tapping, and the results showed no differences between insomniacs and controls on objective performance, but revealed significant differences on subjective measures of performance.

Cognitive Bias and Memory Performance in Patients with Persistent Insomnia

TL;DR: In this paper, the authors compared 20 patients with primary insomnia with 20 normal controls on a modified version of the emotional Stroop test, and tests of explicit and implicit memory for threat words and non-threat words, and found that the insomniacs had a prolonged Stroop latency for sleep words but so did the controls, and there was no group difference on Stroop interference of sleep words.

Chronic Insomnia and Daytime Functioning: An Ambulatory Assessment

TL;DR: In this paper, the relation between daytime functioning and chronic insomnia was investigated, and subjective well-being was found to be compromised in insomniacs as compared to control participants, but no differences in the level of performance were found.

Are individuals with paradoxical insomnia more hyperaroused than individuals with psychophysiological insomnia? Event-related potentials measures at the peri-onset of sleep.

TL;DR: Psy-I appear to present an inability to inhibit information processing during sleep onset, while Para-I seem to present overall enhanced attentional processing that results in a greater need for inhibition.
