A 2015 article explains that the number of heart attack patients admitted to Michigan hospitals from 2010 to 2013 increased by 25% on the Monday following the daylight saving time change.
The article also states that a 2012 University of Alabama study found that losing an hour of your day equates to a 10% increase in heart attack risk within 48 hours of the change. It should be noted that stepping back an hour (as we just did) means 10% less risk of a heart attack during the same time period.
