Lifestyle changes suggested for maintaining heart health include adopting a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Regular physical activity—aiming for at least 150 minutes of moderate exercise per week—is essential. Additionally, quitting smoking and reducing alcohol consumption can significantly lower heart disease risk. Managing stress through mindfulness practices, yoga, or meditation helps, along with regular health check-ups to monitor blood pressure, cholesterol, and other risk factors. These combined efforts can lead to improved heart health and overall well-being.
