Your heart needs energy continuously, as it is a muscle that never stops working to pump blood throughout your body. It requires energy at all times, particularly during periods of increased physical activity, stress, or emotional strain when the demand for oxygen and nutrients rises. The heart primarily generates energy through aerobic metabolism, utilizing oxygen to produce ATP, the energy currency of cells. Additionally, during intense exertion, it can also rely on anaerobic processes to meet its energy needs.
