Preliminary research out of Finland found the overall rate for stroke to be 8 percent higher for two days following daylight saving time, CNN reports. People with cancer were 25 percent more likely to experience stroke, according to the study. And people over 65 were 20 percent more likely to have a stroke.
However, the director of the stroke center at University Hospital’s Case Medical Center in Cleveland pointed out daylight saving time doesn’t necessarily cause stroke. Dr. Cathy Sila said that if occasionally losing or gaining an hour of sleep was a major stroke risk factor then it would happen with regularity with airline passengers flying from coast to coast.
Sila suggested people with breathing-related issues should discuss their concerns with their physician. She said risk factors for stroke include the following: high blood pressure, high cholesterol, high blood sugar, smoking, obesity and not exercising.
