Blood Pressure FAQ
Everything you need to know about blood pressure readings, categories, and maintaining optimal heart health.
A normal blood pressure reading is a systolic pressure of less than 120 mmHg and a diastolic pressure of less than 80 mmHg. Maintaining normal blood pressure is crucial for reducing the risk of heart disease and stroke.
Systolic pressure (the top number) measures the force of blood against your artery walls when your heart beats. Diastolic pressure (the bottom number) measures the force of blood against your artery walls while your heart rests between beats.
A hypertensive crisis is a severe increase in blood pressure where the systolic reading is over 180 mmHg and/or the diastolic reading is over 120 mmHg. This is a medical emergency requiring immediate attention to prevent life-threatening complications like a stroke or heart attack.
If your blood pressure is normal (below 120/80), you should check it at least once every two years. If you have elevated blood pressure or hypertension, your doctor may recommend checking it daily or weekly to monitor your condition and treatment effectiveness.
Several factors can temporarily affect your blood pressure, including stress, caffeine, nicotine, physical activity, a full bladder, and even the time of day. For the most accurate reading, rest quietly for 5 minutes before measuring, avoid caffeine/exercise 30 minutes prior, and ensure your arm is supported at heart level.
