According to Angela Pepdjonovic, a physical therapist at the Hospital for Special Surgery in New York, 'Your heart has to work a little bit harder to pump blood around your body during exercise, particularly in the cold ... This can help to boost your endurance over time as this enhances your body's ability to regulate temperature efficiently.'
Without proper precautions, folks with these kinds of conditions are at risk of complications 'because, essentially, the cold air is constricting some of the blood vessels in the lungs, which disrupts some of the airflow and can make it harder to breathe.'
