Improving cardiovascular health can be achieved through several effective methods. Regular aerobic exercise, such as running, cycling, or swimming, strengthens the heart and improves blood circulation. Incorporating high-intensity interval training (HIIT) can also enhance cardiovascular fitness by pushing the heart rate to challenging levels. Maintaining a balanced diet rich in fruits, vegetables, whole grains, and healthy fats primarily supports heart health. Additionally, monitoring blood pressure and cholesterol levels and managing stress through relaxation techniques can further enhance overall cardiovascular health, leading to a reduced risk of heart disease.
