Caffeine Consumption and Sleep Quality in Australian Adults

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4997392/Journal: NutrientsPublication Date: 08/2016Summary: Caffeine is commonly consumed to help offset fatigue, however, it can have several negative effects on sleep quality and quantity. 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 …

Caffeine Effects on Sleep Taken 0, 3, or 6 Hours before Going to Bed

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3805807/Journal: NutrientsPublication Date: 08/2016Summary: The magnitude of reduction in total sleep time suggests that caffeine taken 6 hours before bedtime has important disruptive effects on sleep and provides empirical support for sleep hygiene recommendations to refrain from substantial caffeine use for a minimum of 6 hours prior to bedtime.

Effects of caffeine on sleep quality and daytime functioning

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6292246/Journal: Risk Management and Healthcare PolicyPublication Date: 12/2018Summary: Caffeine (particularly in the form of coffee) is one of the most widely consumed stimulants in the world, with 90% of American adults consuming caffeine-infused beverages almost daily. While there is substantial evidence that caffeine enhances performance, caffeine withdrawal leads to deficits at both the individual …

The Temperature Dependence of Sleep

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6491889/Journal: Frontiers in NeurosciencePublication Date: 04/2019Summary: Mammals have evolved a range of behavioural and neurological mechanisms that coordinate cycles of thermoregulation and sleep. 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 …

Sleep duration and the risk of breast cancer: the Ohsaki Cohort Study

URL: https://www.nature.com/articles/6604684Journal: British Journal of CancerPublication Date: 09/2008Summary: In a prospective study of 23 995 Japanese women, short sleep duration was associated with higher risk of breast cancer (143 cases), compared with women who slept 7 h per day, the multivariate hazard ratio of those who slept ⩽6 h per day was 1.62 (95% confidence interval: 1.05–2.50; P …

Sleep Duration as a Risk Factor for Cardiovascular Disease- a Review of the Recent Literature

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2845795/Journal: Current Cardiology ReviewsPublication Date: 02/2010Summary: Sleep loss is a common condition in developed countries, with evidence showing that people in Western countries are sleeping on average only 6.8 hour (hr) per night, 1.5 hr less than a century ago. Although the effects of sleep deprivation on our organs have been obscure, recent epidemiological …

Role of Sleep and Sleep Loss in Hormonal Release and Metabolism

URL: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3065172/Journal: Pediatric NeuroendocrinologyPublication Date: 11/2009Summary: Compared to a few decades ago, adults, as well as children, sleep less. 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 …

Short-term sleep deprivation with exposure to nocturnal light alters mitochondrial bioenergetics in Drosophila

URL: https://www.sciencedirect.com/science/article/abs/pii/S0891584918307263Journal: Free Radical Biology and MedicinePublication Date: 05/2018Summary: Many studies have shown the effects of sleep deprivation in several aspects of health and disease. 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 …

A single night of partial sleep deprivation induces insulin resistance in multiple metabolic pathways in healthy subjects

URL: https://pubmed.ncbi.nlm.nih.gov/20371664/ Journal: The Journal of Clinical Endocrinology & Metabolism Publication Date: 06/2010 Summary: Partial sleep deprivation during only a single night induces insulin resistance in multiple metabolic pathways in healthy subjects. This physiological observation may be of relevance for variations in glucoregulation in patients with type 1 and type 2 diabetes.

Sleep disorders and the development of insulin resistance and obesity

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 …
