Self-hypotensive methods for low blood pressure include a sensible diet, moderate exercise, and taking medication as prescribed by a doctor if necessary. Low blood pressure is diastolic blood pressure, and diastolic blood pressure ≥90mmHg measured more than three times on non-same day can also be diagnosed as high blood pressure. Self-hypotensive methods for low blood pressure include reasonable diet, moderate exercise, and taking medication as prescribed by the doctor when necessary. 1. Reasonable diet: Healthy diet is crucial for patients with high BP. It is recommended that such patients should eat a low-salt, low-fat, low-cholesterol diet and consume fresh vegetables and fruits. Adequate supplementation of potassium-containing foods, such as hawthorn, mushrooms, bananas, and grains and cereals, can help maintain stable blood pressure. 2. Moderate exercise: For patients with high blood pressure, it is recommended to do moderate aerobic exercise, such as walking, yoga, etc., and try to avoid strenuous activities such as mountain climbing, fast running and rock climbing. 3. Take medication according to doctor’s prescription: If it is still difficult to control through diet and exercise, it is recommended to take appropriate antihypertensive medication according to doctor’s prescription, such as nifedipine controlled-release tablets, valsartan and so on. Patients with high blood pressure should take medication under the guidance of a doctor and undergo regular checkups, and if their blood pressure fluctuates greatly, they should consult a doctor immediately.
