Daylight saving time has minimal effect on heart health

The Mayo Clinic said the impact of daylight saving time on heart health is likely minimal.

In a nationwide study, researchers applied an advanced statistical model to look for any connections between daylight saving time and serious cardiovascular problems, including heart attacks and strokes.

Researchers focused on the week directly after the spring and fall daylight saving time transition, when clocks are set either an hour forward or backward.

In the Mayo Clinic study, the Monday and Friday following the spring daylight saving time transition showed a slight statistical increase in the rates of cardiovascular events but when looking at all the data, researchers did not see the rise as clinically significant. Daylight saving time began on March 10.
