To improve heart health, individuals can make several important adjustments. Adopting a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can significantly lower cholesterol and blood pressure. Regular exercise strengthens the heart muscle and enhances circulation. Additionally, eliminating or reducing smoking and limiting alcohol intake contribute positively. Managing stress through mindfulness and getting enough sleep are also crucial for maintaining heart health. Regular health check-ups to monitor factors like blood pressure and cholesterol levels play a vital role in prevention.
