As people across Minnesota break out the shovels and snow blowers, doctors are reminding everyone to give your heart a break. They worry about patients who aren’t accustomed to exercising and then try to lift a lot of heavy snow. It’s recommended that you loosen your muscles before starting, then take things slowly. If you start to feel dizzy, take a break immediately. Also, if you feel signs of a heart attack or heart condition – such as squeezing chest pain that may radiate to the neck, shoulder, arm or jaw, or cold sweats, nausea or vomiting – take a break immediately – and if the pain doesn’t go away call 911.
