Insomnia Raises High Blood Pressure

Friday, 08 June 2012 01:01 PM

A sleepless night doesn’t just affect your alertness in the morning. New research has found people with insomnia are far more likely to develop high blood pressure.
The study, by researchers at the Henry Ford Center for Sleep Disorders, also found that the severity of hypertension in insomniacs is highest in those who have the hardest time getting to sleep and those who wake often during the night.
"The cause of hypertension in insomniacs is due to the number of times the individual wakes during the night as well as their sleep latency – the length of time it takes to accomplish the transition from full wakefulness to sleep," said lead researcher Christopher Drake, a sleep specialist with the Henry Ford center. "We found that the longer it took the subjects to fall asleep and more times they woke during the night, the more severe their hypertension."
For the study, to be presented at the Sleep 2012 Conference in Boston next week, Drake and his colleagues compared 5,314 insomniacs to people with normal sleep habits using an Internet-based questionnaire. The survey sought to examine patterns of insomnia symptoms, presence and severity of hypertension and sleep and health habits.
Researchers calculated the increased risks for high blood pressure in insomniacs by comparing their rates of hypertension to those with normal sleeping patterns.
Up to 15 percent of adults say they have chronic insomnia, the inability to fall asleep or remain asleep, and as many as 4 in 10 Americans have some symptoms of insomnia. It is the most common sleep complaint among Americans, according to the National Center for Sleep Disorders Research at the National Institutes of Health.
