INDIANAPOLIS, Ind. (Mar. 11, 2016)– Daylight saving time is back. We’re getting ready to spring forward this weekend and that means we lose an hour of sleep.

New research from Finland shows the time change could have an impact on our health, possibly leading to strokes.

The first few days after the time switch our bodies are getting adjusted to losing that hour of rest. IU Health Neurologist Dr. Robert Pascuzzi says there are some changes our bodies may go through to support the study’s initial findings.

“You have a lot of things happening during sleep and missing an hour may have an impact on the body that’s enough to alter your risk of having a stroke or heart attack,” said Dr. Pascuzzi.

Researchers in Finland looked at strokes and daylight saving time over ten years. Researchers found the overall rate for stroke was eight percent higher the two days after daylight saving time.

People with cancer were 25 percent more likely while those 65 years and older were 20 percent more likely to have a stroke in that time period. Dr. Robert Pascuzzi with the IU Health Neuroscience Center says multiple factors could play into those numbers.

“You might just have stress from worrying about if you’re going to get up on time. Are you setting your alarms properly? Are you forgetting the days changed? And that stress itself may make your blood pressure go up which makes you more likely to have a stroke,” said Dr. Pascuzzi.

Researchers are still looking at the direct correlation between daylight saving and stroke. While some people may not have any reaction to losing an hour of sleep Dr. Pascuzzi says everyone reacts different to even the slightest change.

“So it could be that there’s an impact of one hour less sleep that comes on suddenly that in occasional patients does have an impact on their body chemistry, their hormonal function, their blood pressure regulation, their heart rhythm,” said Dr. Pascuzzi.

A list of risk factors can heighten your chances of having a stroke, like high blood pressure, diabetes, smoking and being overweight.

Doctors say time is the most crucial element if you think you’re having a stroke or experience paralysis or numbness on one side of your body or have trouble with speech go to the hospital immediately.
