Sleep as restitution: an introduction

Abstract

This paper summarizes a symposium that has shown that sleep is a state of altered metabolism, and that disturbances and curtailments of sleep have far-reaching effects on endocrinology, immunology and metabolism, changes that may be linked to disease. As yet, the entire causal chain is weak but there are indications that, in particular, the risk of type 2 diabetes and cardiovascular disease may result from disturbed sleep. It is hypothesized that both insulin resistance and chronic low-grade inflammation may be involved.

Sleep duration and health status self-assessment (SF-36) in the elderly: a population-based study (ISA-Camp 2008)

“…These findings corroborate with those of the literature that show that sleep deprivation is associated with mood, tension and fatigue 14,15 , especially with the advance in age 14 . The study carried out by Faubel et al 25 found differences in mean SF-36 scores for all scale of the mental component in the adjusted analyses only in women, with a greater magnitude of association for role-emotional scale.…”

“…Literature also suggests that good quality sleep provides for daily recovery from physical and mental stresses, improves mood, concentration and memory and reduces the risk of accidents 8,14,15 .…”

Sleep disturbance as a predictor of type 2 diabetes mellitus in men and women from the general population

“…Until now, the mechanism behind the positive association between sleep restriction and fragmentation and type 2 diabetes is not entirely clear. There is evidence that sleep disorders are associated with an increase in sympathetic activity [16,17]. Sympathetic hyperactivity can alter glucose homeostasis and induce insulin resistance by increasing glycogen breakdown and gluconeogenesis.…”

Single Channel Wireless EEG: Proposed Application in Train Drivers

“…Train drivers are required to work in a 24-hour irregular and rotating shifts, including weekends [37], and irregular shifts are related to increased fatigue level and have been correlated to higher risk of fatigue-related accidents [38]. Therefore, there is a need for an automated and non-intrusive fatigue countermeasure device for drivers in this environment.…”
