Emphasizing a healthy lifestyle is an effective treatment for any hypertensive patient (including normal hypertension) at any time, which can lower blood pressure and control other risk factors and clinical conditions, and all patients should adopt it. A healthy lifestyle includes: ① reducing sodium intake and increasing potassium intake. China is a country with a high-salt diet, which is characterized by high sodium and low potassium.
