A new study found that when the weather is cold and cloudy, more people have heart attacks





Colder temperatures can affect heart health and increase cardiovascular disease. So, if on the one hand that gray and gloomy weather can put you in a bad mood, on the other it would also be capable of putting us at risk of heart attack. Because?

This is what emerges from a study by some cardiologists from the University of Lund, in Sweden, the largest of its kind, ready to note that the incidence of heart attacks is highest on days with temperatures below freezing.

In short, the cold months and bad weather can not only lead us to a real depressive state, but would also put our little heart in serious danger.

Scientists looked at data from over 274 patients across Sweden who had heart attacks between 1998 and 2013 and for whom meteorological data such as average, minimum and maximum air temperatures, wind speed, duration were available. sun, atmospheric pressure, air humidity, snowfall, rainfall and temperature changes.

The results showed that the incidence of heart attacks increased with lower air temperature and atmospheric pressure, higher wind speed and shorter duration of the sun.
The incidence of heart attacks was highest on days with sub-zero air temperatures, with rates declining significantly as temperatures rose above 3-4 ° C. The association with air temperature has also occurred for several types of heart attack, including the most common type, caused by blockage of a major coronary artery, an important blood vessel that supplies the heart.

Scientists speculate that cold can cause arteries to narrow, putting additional pressure on the heart. "The cold and windy climate leads to a contraction of blood vessels in the skin to conserve energy and temperature," explains David Erlinge, professor of cardiology at Lund University. This increases the workload of the heart, increasing the risk of a heart attack ”.



Other possible explanations? Undoubtedly, changes in behavior during colder periods, alterations in diet or exercise habits and an increase in respiratory infections, which have also been associated with an increased risk of heart attack.

For the rest? Take advantage of the fact that we live in the land of the sun to stock up on it as soon as we have the opportunity, even in the winter months. The sun warms, is good for you, puts you in a good mood and is certainly good for the heart!
