Final answer:
During exercise, your body releases heat by using stored energy and increasing breathing.
Step-by-step explanation:
During exercise, your body releases heat by using stored energy. As you move and exert energy, your body breaks down stored carbohydrates and fats, releasing heat as a byproduct. This helps regulate your body temperature and prevent overheating. Additionally, increasing breathing during exercise helps expel heat through the process of evaporation, as sweat on your skin evaporates and cools you down.
