Utah Winter Weather and Physical Activity: “Exercise” Caution

Salt Lake County, UT - Many people spent December at home with their family and friends, making resolutions to increase their physical activity and follow-up on medical concerns in January. With the cold air of January upon us, and as more people increase their activity in the community and at recreation centers, exercising caution while physically exercising is crucial to one's health.

December and January tend to be the highest months for stroke and heart attack. The two most prevalent theories to explain this data are:

  • Air pollution: even sort-term exposure to pollutants is associated with heart attacks and strokes. Pollutants enter the bloodstream, via the lungs, where they initiate an inflammatory response. This can lead to blood clots in the arteries—a risk factor for heart attacks and strokes.
  • Influenza: infections are high during winter and there is a known association between the flu virus and cardiovascular disease. The flu virus affects inflammatory and blood-clotting pathways, which can cause fatty deposits on the artery wall (plaque) to break loose, leading to coronary artery blockage—the main cause of heart attacks.

"It's a good idea to consult with your medical provider prior to beginning or re-engaging in an exercise program or routine," said Dr. Angela Dunn, executive director of Salt Lake County Health Department, "and it's wise—and more fun—to exercise with a partner or friend."

"Exercising and swimming with others is a safety measure that we encourage at our recreation centers and pools," Salt Lake County Parks and Recreation Communications and Public Relations Manager Callista Pearson advised. "When you have someone with you, they can look out for you, and vice versa."

Health officials encourage people to remain physically active year-round to reduce the risk of cardiovascular disease and other health concerns. During periods of poor air quality, exercise indoors (such as at a Salt Lake County Recreation Center) or wear an N95, or stronger, face mask when exercising outside to reduce exposure to pollutants. It's also important to receive an annual influenza vaccine to reduce your chance of getting the flu and the negative consequences of the flu: the flu vaccine is associated with reduced cardiovascular incidents.
