ROCKFORD (WREX) — More heart attacks happen when the weather is cold, according to a new large study.
The study is based on 16 years of medical and weather data.
Scientists link the increase to lower air temperature, lower atmospheric pressure, higher winds and less sunshine. The biggest effect on heart attacks, though, is temperature.
“When you have to be outside if you have heart problems already and it’s very cold, you want to dress warm,” Dr. Shaun Kurien, a cardiologist with OSF Saint Anthony Medical Center says. “You want to dress in layers. The more layers you wear the better, because the air in between kind of acts as insulation. You want to make sure you cover your head because you lose a lot of heat toward your head, and you want minimize how much time you have to stay outside.”
Symptoms to watch for are chest pain, pain in the neck or throat, and shortness of breath.
