Twery In the News
Children with sleep apnea syndrome who have their tonsils and adenoids removed sleep better, are less restless and impulsive, and report a generally better quality of life, finds a new study funded by the National Institutes of Health. However, the study found cognitive abilities did not improve compared with children who did not have surgery, and researchers say the findings don’t mean surgery is an automatic first choice.
With so many demands on our time, we often sacrifice sleep to fit everything into our days. But sleep affects both mental and physical health, and lack of sleep can have serious consequences. “Sleep affects almost every tissue in our bodies,” says Dr. Michael Twery, a sleep expert at NIH. “It affects growth and stress hormones, our immune system, appetite, breathing, blood pressure and cardiovascular health.”
Is it difficult for you to fall asleep or stay asleep through the night? Do you wake up feeling tired? Do you feel sleepy during the day, even if you think you've had enough sleep? You might have a sleep disorder. There are many treatments for sleep disorders and ways to make sure you are getting enough healthy sleep.
Dr. Michael Twery, director of the National Center on Sleep Disorders Research, touches on the significance, and contributions, of the NHLBI-supported Wisconsin Sleep Cohort Study, which was the first population-based study to link untreated sleep apnea with an increased risk of cardiovascular disease and mortality, setting the stage for subsequent studies.
Moderate to severe obstructive sleep apnea is associated with an increased risk of death from any cause in middle-aged adults, especially men, according to new results from a landmark study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH). The new findings provide the strongest evidence to date of a link between increased risk of death and sleep apnea, a common disorder in which the upper airway is intermittently narrowed during sleep, causing breathing to be difficult or completely blocked.
Sleep-disordered breathing (also known as sleep apnea) is associated with an increased risk of death, according to new results from the Wisconsin Sleep Cohort, an 18-year observational study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. Researchers found that adults (ages 30 to 60) with sleep-disordered breathing at the start of the study were two to three times more likely to die from any cause compared to those who did not have sleep-disordered breathing.
Experts estimate that about one-third of adult Americans will experience some sort of sleep disorder in their life time. And, while many sleep disorders can be treated, most of them go undiagnosed.
When sleep is regularly disrupted throughout the night, the consequences can be dire, from dangerously sleepy driving to higher risks of diabetes and heart disease.
In today's "24/7" society, many people cut back on sleep to squeeze in more time for work, family obligations, and other activities. But skimping on sleep can be harmful. A comprehensive new handbook from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) explains that sleep is not merely "down time" when the brain shuts off and the body rests.
The National Heart, Lung, and Blood Institute (NHLBI) today launched Mission Z, a new and expanded Web site to educate young children - their parents, teachers, and pediatricians - about the importance of adequate nighttime sleep for children. The site, hosted by Garfield, the Campaign "spokescat," features an online mystery for children to solve, along with other games and downloadable features that provide information about the importance of sleep. The site also contains special resources for parents, teachers, and pediatricians to use in helping children get the sleep they need.
Ever wonder why you sleep, or why you don't do your best when you don't get enough sleep? Biomedical researchers have only recently begun to understand how important sleep is to human health and functioning. Now, the latest, most accurate information on sleep and sleep disorders is available online.
The discovery of the gene for narcolepsy in dogs by Dr. Emmanuel Mignot and his group at Stanford University School of Medicine has particular importance and significance for the fields of sleep and neurology and for patients with sleep disorders.
Dr. Mignot's study, funded by the National Institutes of Health and published in the August 6 issue of Cell, opens the door to identification of the narcolepsy gene in humans and to development of new treatment approaches and possibly a cure for this disabling sleep disorder.
Shift workers and teens, among the most vulnerable to a drowsiness-related highway crash, are a target of programs to combat the problem, two federal agencies have announced in a collaborative report to Congress.
The National Highway Traffic Safety Administration (NHTSA) - collaborating on these programs with the National Center on Sleep Disorders Research (NCSDR) at the National Institutes of Health's National Heart, Lung and Blood Institute - conservatively estimates that 40,000 injuries and 1,550 fatalities annually are attributable to drowsy drivers.
