The clocks move forward one hour on March 11, as most of the U.S. goes on Daylight Savings time. In addition to arriving early at appointments if you forget to reset your clocks, you could be at greater risk for a heart attack.
“The Monday and Tuesday after moving the clocks ahead one hour in March is associated with a 10 percent increase in the risk of having a heart attack,” said Martin Young, an associate professor at the University of Alabama Birmingham (UAB). “The opposite is true when falling back in October. This risk decreases by about 10 percent.”
The Sunday morning of the time change doesn’t require an abrupt schedule change, but, Young says, heart-attack risk peaks on Monday when most people rise earlier to go to work.
