A sedentary lifestyle can have a serious negative impact on your heart health. Lack of physical activity can lead to obesity, high blood pressure, and elevated cholesterol levels, all of which are significant risk factors for heart disease. When you are inactive, your heart has to work harder to pump blood, which can lead to cardiovascular issues. It's essential to incorporate regular physical activity into your daily routine, such as walking, cycling, or engaging in sports, to keep your heart healthy. The NHS recommends aiming for at least 150 minutes of moderate-intensity exercise each week to help maintain heart health.
