![]() Today, sleep is characterized using polysomnography. ![]() ![]() In order to understand the consequences and effects of sleep disturbances and how these may be ameliorated, it is important to be able to analyze the neurobiology of sleep. 5 Chronic sleep restriction is associated with an increase in sleep propensity - even in inconvenient and dangerous situations - a deterioration of daytime performance, including memory, and a number of physiologic consequences, including adverse effects on endocrine functions and immune responses 6 and an increase in the risk of obesity and diabetes. In a recent large study of working adult Americans, 16% of respondents reported sleeping less than 6 hours per night on work days. This attests to the homeostatic drive for sleep beyond a few days, heroic measures must be taken to keep humans awake.Īlthough less dramatic, the effects of sleep disturbances may be of more practical use in helping us to understand the consequences of normally occurring voluntary sleep loss and sleep loss associated with sleep disorders. 3, 4 In the absence of a disorder, total sleep deprivation does not occur over prolonged periods of time. 2 In humans, the rare hereditary condition, fatal familial insomnia, which is associated with a progressive inability to sleep, invariably leads to death, with a time course of between 8 and 72 months. 1 Death associated with chronic sleep deprivation has also been reported in other species. In rodents, total sleep deprivation results in a large rise in energy expenditure and consequent weight loss, despite increased food intake and - unless sleep deprivation is halted - it leads to death, usually in 2–3 weeks. Sleep is a behavior observed in all living organisms and is necessary for survival.
