NEW YORK (Reuters Health) - Poor quality sleep - whether from insomnia, sleep fragmentation, or nightmares - is associated with increased risk of death, according to several presentations this week in Seattle at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.
One study, conducted at Penn State College of Medicine in Hershey, Pennsylvania, suggests that insomnia may be as hazardous as obstructive sleep apnea.
"Insomnia with objective short sleep duration is associated with an activation of the stress system, i.e., higher secretion of cortisol and increased risk of high blood pressure," said lead author Dr. Alexandros Vgontzas. He and his associates examined the effects of insomnia that persisted for at least 1 year and objective short sleep duration on mortality.
