High blood pressure (hypertension) often has no symptoms, which is why it's called the silent killer. Warning signs that may indicate dangerously high pressure include severe headache, nosebleeds, visual changes, chest pain, and shortness of breath. If you experience these, seek medical attention promptly. Lifestyle interventions that genuinely lower blood pressure: reduce sodium intake (under 2,300mg daily), the DASH diet (high in fruits, vegetables, whole grains, low-fat dairy), regular aerobic exercise (150 minutes moderate per week), maintaining healthy weight, limiting alcohol, and stopping smoking. For practical sodium reduction: cook at home instead of eating processed or restaurant food. Read labels — bread, sauces, and ready meals contain surprisingly high sodium. Use herbs and spices instead of salt. Monitor at home with a validated blood pressure monitor. Take readings at the same time daily, after sitting quietly for 5 minutes. Keep a log to share with your doctor. A single high reading doesn't diagnose hypertension — it's patterns over time.
