Researchers at the University of Galway, Ireland, recently conducted a study on sleep duration and its effect on increasing the risk of stroke. They analyzed data from 5,000 participants with an average age of 62, half of whom had previously suffered a stroke, according to pre-filled questionnaires.
The results showed that people who slept more than nine hours a night were twice as likely to suffer a stroke as those who slept seven hours. The data also showed that people who sleep less than five hours a night are three times more likely to have a stroke.
In the group of people with a previous stroke, 151 people slept more than nine hours and 162 people slept less than five hours. In the group where no one had had a stroke, 84 people slept more than nine hours and 43 people slept less than five hours.
“Our results suggest that sleep should be one of the priority areas for stroke prevention. Further consultations with people who have difficulty sleeping would be helpful early on,” said Christine McCarthy, sleep specialist and lead author of the study, whose findings were published in the journal.
It’s not yet known exactly how excessive sleep increases the risk of stroke, but researchers say it’s a possible indicator of other health problems. Risk factors include physical inactivity, anemia or depression, which are known to increase the risk of stroke.
On the other hand, lack of sleep has been shown to increase the risk of stroke due to higher blood pressure, inflammation or increased risk of obesity and diabetes.
People with sleep apnea are also at higher risk of stroke. This is a condition in which breathing repeatedly stops during sleep.
