According to a new study conducted at St. Michael’s Hospital in Toronto, Canada, adults who suffer from insomnia don’t have to worry about the potential for high blood pressure.

There have been increased concerns about the potential health consequences of insomnia, particularly to the cardiovascular system. According to the CDC, approximately 67 million American adults have high blood pressure, and a quarter report a lack of adequate sleep. Nearly 10 percent experience chronic insomnia.

Dr. Nicholas Vozoris, a respirologist at St. Michael’s, says that if a link did exist between the two, not only would a large part of the population need long-term screening for the potential to develop high blood pressure, but physicians would also be prescribing more sleeping pills in order to treat insomnia in patients.

“After adjusting for many factors, including whether or not participants were receiving blood pressure pills or sleeping pills, there were generally no associations between insomnia and high blood pressure, even among people who were suffering from insomnia the most often. These results should reassure patients and their doctors that insomnia and high blood pressure are unlikely to be linked,” said Dr. Vozoris in a statement.

Previous research suggested a potential link between insomnia and high blood pressure, though these studies were only based on a small number of participants.

Dr. Vozoris’ study examined data from approximately 13,000 Americans, and after adjusting for a number of factors, no link was found between the two health conditions.

The findings of the study are published in the Journal of Clinical Psychiatry.
