Preventing heart disease involves making a series of positive lifestyle changes. Start by adopting a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while limiting saturated fats and sugars. Regular physical activity, ideally 150 minutes of moderate exercise per week, can significantly improve heart health. It's also essential to avoid smoking and limit alcohol consumption. Managing stress through relaxation techniques and ensuring adequate sleep are crucial as well. Regular health check-ups with your GP can help monitor risk factors like blood pressure and cholesterol levels. Small, consistent changes can lead to significant improvements in your heart health over time.
