According to at least one study, on Monday after DST began, heart attacks increased by 24% overall. That compares with the daily average heart attack reported in the weeks around the same date. To further encourage this trip, on the Monday after DST ended and we gained those extra hours, heart attacks reportedly fell 21%. Now, all the numbers are a little out on the weekly timeline, showing that it’s only people who will have a heart attack still get one extra boost. But … maybe you can give yourself extra hours of sleep, just in case.
In fact, the number of heart attacks increased 24 percent on Monday after summer time, compared to the daily average for weeks around the beginning of summer time, according to a 2014 study in the journal Open Heart.
With this in mind, people who are at risk of having a heart attack – such as those who smoke, have a strong family history of a heart attack or have high cholesterol or high blood pressure – should not delay a trip to the emergency room if they feel chest pain, researchers say senior Dr. Hitinder Gurm, an interventional cardiologist and professor of internal medicine at RSUP Dr.
Aside from an increase in heart attacks after people lose an hour of sleep, the researchers also found that on Tuesday after the end of summer time in autumn, when people get one hour of sleep, the number of heart attacks dropped by 21 percent.
