Physical inactivity has detrimental effects on cardiovascular health. Regular exercise is crucial for maintaining heart health, as it helps regulate blood pressure, cholesterol levels, and aerobic fitness. A sedentary lifestyle can lead to conditions such as obesity, hypertension, and higher risk for heart disease. Additionally, inactivity can contribute to poor blood circulation and decrease the overall efficiency of the heart. Incorporating regular exercise into daily life can counteract these risks, promoting cardiovascular health through improved function and reduced strain on the heart.
