Our hearts are sensitive to changes in weather. Adding more evidence to this link, researchers have made a remarkable discovery about the effects of short-term cold exposure on heart health. Even a small drop in temperature, with just one unit over two to six days, can increase the risk of a heart attack by up to 11%, a recent study revealed.
In the latest study published in the JACC Journals, the researchers examined the short-term effects of lower air temperature and cold spells on the risk of hospitalization for various types of myocardial infarction among 120,380 individuals from the SWEDEHEART registry in Sweden.
