The aim of this study was to determine the relationship between caffeine consumption and sleep quality in adults using a newly validated caffeine food frequency questionnaire (C-FFQ). In this cross …

While there is substantial evidence that caffeine enhances performance, caffeine withdrawal leads to deficits at both the individual …

Whether diurnal or nocturnal, sleep onset and a reduction in core temperature occur together. Non-rapid eye movement (NREM) sleep episodes are also accompanied by core and brain cooling. Thermoregulatory behaviours, like nest …

Although the effects of sleep deprivation on our organs have been obscure, recent epidemiological …

Sleeping as little as possible is often seen as an admirable behavior in contemporary society. However, sleep plays a major role in neuroendocrine function and glucose metabolism. Evidence that the curtailment of sleep duration may have adverse …

However, little is known about how mitochondrial bioenergetics function is affected under this condition. To clarify this, we developed a simple model of short-term sleep deprivation, in which fruit-flies were …

This physiological observation may be of relevance for variations in glucoregulation in patients with type 1 and type 2 diabetes.

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3767932/ Journal: Endocrinology and Metabolism Clinics of North America Publication Date: 09/2014 Summary: Sleep, which comprises a third of the human lifespan, consists of two major states, non-rapid eye movement (NREM, stages N1–3) and rapid eye movement (REM). Sleep is a physiologic state of decreased metabolism and likely serves a reparative role, marked by increased …
