Sleep Problems & Disorders - Excessive Sleepiness
Children who have learning, attention, and behavior problems may be suffering from excessive daytime sleepiness even though clinical tests show they received enough sleep.
Penn State researchers studied 508 children and found that those whose parents reported excessive daytime sleepiness despite getting enough sleep were more likely to experience learning, attention, and behavior problems.
Short sleep duration increases expression of genetic risks for high body mass index
Toss out another old wives' tale: Sleeping too much does not make you fat. Quite the opposite, according to a new study examining sleep and body mass index (BMI) in twins, which found that sleeping more than nine hours a night may actually suppress genetic influences on body weight.
You always hear about health problems associated with people not getting enough sleep, but what about getting too much sleep? According to a study in the European Journal of Neurology, sleeping nine hours or more every day might increase your risk for dementia. The study, conducted by researchers in Spain, followed 3,286 adults age 65 and over for three years. Participants were screened for dementia and reported their daily sleep duration, which included night-time sleep and daytime napping.
Older adults with extreme sleep durations — less than five hours or more than 10 hours — had a markedly worse health-related quality of life compared with those who slept seven hours, according to an article in the journal SLEEP. The study, conducted by researchers at the Universidad Autónoma de Madrid in Spain, followed 3,834 people aged 60 years and over from 2001 through 2003. Participants filled out questionnaires, and those with extreme sleep durations had worse physical and mental scores.
