June 8, 2023 -- Insomnia can lead to an increased risk of stroke, according to new research. The risk goes up with more symptoms, such as trouble falling or staying asleep, or waking up too early, says the study published in the journalMore than a third of the country suffers from insomnia, the study’s authors note. They wanted to investigate the relationship between the disorder and the occurrence of stroke.
People with five to eight insomnia symptoms had a 51% higher chance of having a stroke than those with no insomnia, after controlling for other risk factors, said a statement accompanying the study.
author and epidemiologist Wendemi Sawadogo, a researcher at the Virginia Commonwealth University in Richmond, in a statement.Poor sleep disrupts metabolism and blood pressure, and causes inflammation, which are stroke factors, Phyllis Zee, MD, director of the Center for Circadian and Sleep Medicine at Northwestern University’s Feinberg School of Medicine in Chicago, told CNN.
