This is partially because many people who shovel snow rarely exercise, according to Harvard Medical School. After several months of inactivity, the resistance of tossing shovels-full of snow or pushing a heavy blower can strain the heart.
One 2020 study from the American Heart Association study found that after only two minutes of snow shoveling, participants’ heart rates exceeded 85% of maximal heart rate. That’s a similar level of exertion that’s usually prescribed for aerobic exercise studies, according to the American Heart Association.
Cold weather exacerbates that strain. Low temperatures can elevate blood pressure and increase the likelihood of forming blood clots, according to Harvard Medical School.
Silver Cross Hospital in New Lenox, Illinois recommends taking these safety measures:
- Do a little bit at a time, with ample breaks
- Dress appropriately. Ensure your hands are covered, wear layers and keep your feet dry and warm
- Listen to your body. If you feel tired or sluggish, it’s time for a hot cocoa break
- If you, a loved one or neighbor begins to show signs of a heart attack, call 911 and seek medical attention immediately
Harvard additionally recommends warming up your muscles before shoveling or snow blowing and staying hydrated." WANE TV15
