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.

compared to normal sleepers who fell asleep quickly, people with insomnia who took more than 14 minutes to fall asleep during the day were three times as likely to have high blood pressure readings or a doctor’s diagnosis of hypertension, the authors report in the journal hypertension. about half of insomniacs and a third of the normal sleepers took more than 14 minutes to fall asleep during the day, tang and vgontzas wrote in the statement. “insomniacs who have either short sleep at night or show signs of hyperalertness during the day are at risk for hypertension,” they wrote. “however, many people who have high blood pressure in (a doctor’s) office setting do not have sustained high blood pressure outside of a medical setting,” he said.
