Exercising in cold weather challenges the body in various ways. The body must expend more energy to maintain core temperature, increasing caloric expenditure. Cold air can also cause vasoconstriction, which reduces blood flow to extremities, potentially leading to frostbite or hypothermia. Moreover, cold temperatures may increase the risk of muscle stiffness or injury. It’s essential to dress in layers, warm up adequately, and stay hydrated to minimize risks and enjoy the benefits of outdoor exercise during colder months.
