april 1, 2009 — insomniacs who sleep less than five hours a night are five times more likely to develop high blood pressure than sound sleepers who get enough rest, a new study shows. but the newly published study is one of the first to find that insomnia also raises the risk for high blood pressure. “we have known for many years that insomniacs have a high risk for depression and other psychiatric disorders,” study researcher alexandros n. vgontzas, md, tells webmd. vgontzas, who directs the sleep research and treatment center at the penn state college of medicine, says the major strength of the new study is that it included both subjective and objective measures of insomnia.




based on their responses to questionnaires designed to assess sleep quality, more than half of the study participants were classified as being normal sleepers, 8% had insomnia with symptoms persisting for at least one year, and 22% were classified as being poor sleepers who had difficulty falling asleep, staying asleep, or had poor-quality sleep. kohler is medical director of the florida sleep institute in spring hill and a spokesman for the american academy of sleep medicine. “there is more awareness about the importance of sleep to our overall health, but despite this, very few physicians adequately screen their patients for sleep problems,” he says. the typical adult needs about eight hours of sleep a night, but kohler says a few people can get by on four or five hours and others need nine or 10.
