Days with strong cold winds are more dangerous for a human to have a heart attack, according to a new Swedish scientific study, the largest of its kind to date, regarding the relationship between bad weather and the possibility of a heart attack.
Climate change affects the chance of a heart attack
The study correlated the number of heart attacks with the weather and found that they clearly affect the chance of a heart attack. It was already known that when it is cold, there is a greater cardiovascular risk, as heart rate and blood pressure can rise due to narrowing of the arteries and blood clotting.
The new study shows that there is a problem when it is just blowing too strong wind. When wind speed reaches seven beauforts, the number of infarctions increases by 7%.
The risk of a heart attack is increased by 14% when the temperature drops to zero. An increase in temperature by about seven degrees Celsius is associated with a reduction in the risk of stroke by almost 3%.
Researchers at the University of Lund, led by Professor David Erlinge, Director of the Department of Cardiology, published the study in the American Journal of Cardiology, JAMA Cardiology, according to the British Journal of Cardiology The New York Times, “analyzed data on 274,000 people aged 72 years who had been stroke for 15 years.
“We do not know whether it really reduces the risk of stroke by staying overnight in a cold and windy day. But we find it reasonable, especially for someone in the risk group. So we advise anyone who wants to go out, dress appropriately, because Climate change affects the chance of a heart attack “said Erlinge.
