operational definition of sleep

The best predictor was the number of ES episodes within the same day followed by frequency per week of moderate to severe sleepiness (Table 3). Ohayon MM, Caulet M, Philip P, Guilleminault C, Priest RG. WebSleep scientists have explored these changes in depth, and their definition of sleep is tied to characteristic patterns of brain waves and other physiological functions. View Source That amount also changes with age. The final sample included 15 929 individuals representative of the general population of these states (138 million). Interestingly, multiple episodes of sleepiness within the same day were reported by half the individuals reporting ES. Spiegel, K., Tasali, E., Leproult, R., & Van Cauter, E.

Nonetheless, these data provide essential information to refine the nosology of hypersomnia disorders by specifying the range and frequency of symptoms together with the threshold of frequency associated with clinically significant impairment, distress, and comorbidities. Although some concepts, like height or age, are easily measured, others, Approximately half the sample (53.5%) were married (or living with a domestic partner), 28.7% were single, 10% were divorced/separated, and 7.8% were widowers. In multivariate models, the number of ES episodes per day and severity of ES were identified as the best predictors for impairment/distress.

When ES symptoms are added and the definition is restricted to recurrence within the same day accompanied by normal sleep duration, a minimum frequency of 3 times per week, and duration of ES of at least 3 months, the prevalence drops to 4.7% and further to 1.5% after applying the differential diagnosis (ie, eliminating sleep disorders that could be responsible for ES). Excessive sleepiness was accompanied by the presence of naps in 28% of cases (7.8% of the sample).

According to Wu, there are two main processes that regulate sleep: circadian rhythms and sleep drive. Circadian rhythms are controlled by a biological clock located in the brain. One key function of this clock is responding to light cues, ramping up production of the hormone melatonin at night, then switching it off when it senses light. These internal links are intended to improve ease of navigation across the site, and are never used as original sources for scientific data or information. built. An operational definition describes how the variables are measured and defined in the study.
