Introduction: Sleep deprivation can impair several physiological systems and recently, new evidence has pointed to the relationship between a lack of sleep and carbohydrate metabolism, consequently resulting in insulin resistance. To minimize this effect, High-Intensity Interval Training (HIIT) is emerging as a potential strategy. Objective: The aim of this study was to investigate the effects ...

Sleep deprivation is common in Western societies and is associated with increased cardiovascular morbidity and mortality in epidemiological studies. However, the effects of partial sleep deprivation on the cardiovascular system are poorly understood. In the present study, we evaluated 13 healthy male volunteers (age: 31 ± 2 yr) monitoring sleep diary and wrist actigraphy during their daily rout...

STUDY OBJECTIVES Previous studies have demonstrated that as little as 18 hours of sleep deprivation can cause deleterious effects on performance. It has also been suggested that sleep deprivation can cause a "tunnel-vision" effect, in which attention is restricted to the center of the visual field. The current study aimed to replicate these behavioral effects and to examine the electrophysiolog...

It is a common belief that sleep deprivation increases the susceptibility to diseases. In order to evaluate the effects of sleep deprivation on immune profile in humans, peripheral venous blood was obtained from sixteen healthy young male volunteers. Ten of the volunteers underwent 48 hours of sleep deprivation and the other six maintained their regular sleep schedule and acted as controls. The...

Sleep is an important physiological process responsible for the maintenance of physical, mental and emotional health of a living being. Sleep deprivation is considered risky for several pathological diseases such as anxiety and motor and cognitive dysfunctions. Sleep deprivation has recently been reported to cause oxidative damage. This study has been designed to explore the possible involvemen...

STUDY OBJECTIVES To verify if error monitoring, involving detection and remedial actions, is affected by sleep deprivation. DESIGN Event-related brain potentials (ERPs) and electroencephalogram spectrum during performance of Flanker task were obtained in a within-subject, counter-balanced, repeated-measures design. SETTING Sleep deprivation and data collection were conducted in a laboratory...

EVIDENCE IS MOUNTING THAT SLEEP IS NOT MERELY A PASSIVE STATE OF RELAXATION TO COMPENSATE FOR FATIGUE ACCUMULATED DURING WAKING HOURS. For example, reports indicate that it plays a role in active modification of host defense functions.1 To evaluate the effects of natural sleep on neuroendocrine immune function, numerous research groups have investigated changes in certain immune functions when ...

Sleep deprivation is common among university students, and has been associated with poor academic performance and physical dysfunction. However, current literature has a narrow focus in regard to domains tested, this study aimed to investigate the effects of a night of sleep deprivation on cognitive and physical performance in students. A randomized controlled crossover study was carried out wi...

Sleep deprivation can be used to investigate the physiology and pathology of human sleep. Previously, human sleep deprivation has been done manually by a sleep expert performing visual online interpretation of the electroencephalogram (EEG). When the subject enters the stage of sleep to deprive the sleep expert disturbs the sleep manually by touching the subject or by activating some kind of st...

The function of sleep in physiology, behaviour and cognition has become a primary focus of neuroscience. Its study inevitably includes experimental sleep deprivation designs. However, concerns exist regarding confounds like stress, increased locomotor activity levels, and decreased motivation to perform operant tasks induced by the methods employed. We here propose a novel procedure for sleep d...
