Common questions about blood pressure measurement and management
A normal blood pressure reading is below 120/80 mmHg according to American Heart Association guidelines. Readings of 120–129 systolic with diastolic below 80 are considered elevated. Stage 1 hypertension begins at 130/80 mmHg.
Sit quietly for 5 minutes before measuring. Use a validated upper-arm cuff at heart level. Avoid caffeine, exercise, and smoking for 30 minutes beforehand. Take two readings one minute apart and record the average. Measure at the same time daily for consistency.
High blood pressure (hypertension) can result from genetics, age, obesity, high sodium intake, lack of exercise, chronic stress, smoking, excessive alcohol, and conditions like diabetes or kidney disease. In many cases the cause is unknown (essential hypertension).
Seek immediate medical care if your blood pressure is 180/120 mmHg or higher, especially with symptoms like chest pain, shortness of breath, back pain, numbness, vision changes, or difficulty speaking. This may indicate a hypertensive crisis.
Lifestyle changes can significantly reduce blood pressure: reduce sodium to under 2,300 mg/day, exercise 150 minutes per week, maintain a healthy weight, limit alcohol, quit smoking, manage stress, and follow the DASH diet rich in fruits, vegetables, and whole grains.
Adults with normal readings should check at least once every 2 years. Those with elevated readings or risk factors should check more frequently — monthly or as directed by a healthcare provider. People diagnosed with hypertension should monitor as recommended by their doctor.
