Obstructive Sleep Apnea Severity And Daytime Functional Impairments Confounded By Short Sleep Duration
A study in the Feb. 1 issue of the journal SLEEP shows that daytime functional impairments in older men with obstructive sleep apnea (OSA) are largely explained by total sleep time rather than OSA severity. A modest link between OSA severity and daytime sleepiness, measured by the Epworth Sleepiness Scale, was no longer statistically significant after controlling for total sleep time.

Sleep and Aging: The Effects of Aging on Sleep and Sleep Patterns
Sleep and aging are closely related. Learn how sleep affects not only aging but also mental health, physical health and memory.

"Millions of Americans suffer from disorders that prevent a full night's sleep, and others - from pilots to combat soldiers - have jobs where sleepiness is a hazard.

Sleep Apnea Linked To The Progression Of Liver Disease

In this study, researchers recruited 90 severely obese patients presenting for bariatric surgery at without known diagnoses of obstructive sleep apnea.
