Cold weather
can trigger
heart attack
is currently increasingly becoming the concern of health experts.Especially after a large study published in JAMA Cardiology showed a strong link between low temperatures and increased cases of heart attacks.
So far, the weather is believed to affect health, starting from seasonal affective disorder, migraines that recur when the weather changes, to a person’s asthma which can be triggered by storms.Now, heart attacks are officially on the list of health risks that worsen as the air gets colder.

The research, which involved data on the incidence of heart attacks throughout Sweden, was analyzed together with weather records from various monitoring stations.
David Erlinge, one of the study authors and Head of the Department of Cardiology at Lund University, explained that most heart attacks occur in conditions of low temperatures, strong winds, minimal sunlight and low atmospheric pressure.
In his research, the risk of heart attack was recorded to be higher when the temperature was below 0 degrees Celsius.The incidence rate decreases when temperatures begin to rise above 3 to 4 degrees Celsius.
“When the minimum temperature drops from 20 degrees to 0 degrees, the risk of heart attack increases by 14 percent,” Erlinge quoted

.
He also noted that a 7.4 degree increase in minimum temperature could reduce the risk of heart attack by 2.8 percent in more than 274 thousand patients observed.
This finding is supported by other researchers.Hong Chen from Health Canada believes that exposure to cold actually has long-term effects.In fact, a number of literature shows that the effects can last up to two to three weeks.
Chen also warned that climate change may make winters more extreme so that the health risks associated with cold temperatures persist even as the earth warms.
What is interesting is that the association between low temperatures and heart attacks is even more pronounced in warmer seasons.This shows that a sudden drop in temperature, although not extreme, can still trigger a stress response in the body.
However, experts emphasize that this study only shows an association, not evidence of direct causation.Ivor Benjamin, President of the American Heart Association, said that the exact mechanism still needs further research.
However, risk factors that are common in winter such as flu or heavy physical activity in cold weather, for example shoveling snow, are thought to play a role.
To reduce the risk, Benjamin recommends that people limit vigorous physical activity when the weather cools, and stay indoors when possible.
Apart from that, it is important to check the condition of those closest to you, especially those who live alone or are at risk of heart disease.
With this variety of scientific evidence, it is clear that cold weather can trigger heart attacks, not just an assumption, but a phenomenon that needs to be watched out for.
When the temperature drops, the body demands more attention.So, don’t ignore the signs and stay healthy, because in the end, cold weather triggering a heart attack can be a real threat to anyone.
