Experts Warn of Increased Heart Risks and Exercise Dangers in Extreme Cold Weather

Cold weather can increase cardiovascular risks by causing blood vessel constriction, raising blood pressure, and increasing heart strain, especially in individuals with heart conditions, hypertension, or respiratory issues. Exercising outdoors in extreme cold may lead to hypothermia, muscle injuries, and respiratory irritation. Reduced physical activity, dehydration, and inflammation during winter further elevate risks of blood clots and sudden cardiac events. Experts advise vulnerable groups to avoid outdoor exercise in severe cold and take preventive measures indoors.
