What is normal blood pressure?
Normal blood pressure is below 120/80 mmHg (systolic below 120 AND diastolic below 80). This is the target range recommended by the American Heart Association.
What do the two numbers in blood pressure mean?
Systolic (top number) measures the pressure when your heart beats. Diastolic (bottom number) measures the pressure between beats when your heart rests. Both are measured in millimeters of mercury (mmHg).
What is considered high blood pressure (hypertension)?
Blood pressure of 130/80 mmHg or higher is considered high (hypertension). Stage 1 is 130-139/80-89 mmHg. Stage 2 is 140/90 mmHg or higher. A hypertensive crisis is above 180/120 mmHg.
When should I seek emergency medical help?
Seek immediate medical attention if your blood pressure exceeds 180/120 mmHg, especially with symptoms like chest pain, shortness of breath, severe headache, vision changes, or difficulty speaking.
How often should I check my blood pressure?
The AHA recommends checking at least once a year if normal. If elevated or high, monitor more frequently (weekly or daily) as recommended by your doctor. Keep a log of your readings.
Can blood pressure vary throughout the day?
Yes, blood pressure naturally fluctuates. It is typically lowest during sleep and rises in the morning. Stress, exercise, caffeine, and posture all affect readings. Take readings at the same time daily for consistency.
What can I do to lower blood pressure naturally?
Lifestyle changes include: regular exercise (150 min/week), DASH diet (rich in fruits, vegetables, whole grains), reducing sodium intake, maintaining healthy weight, limiting alcohol, managing stress, and getting adequate sleep.
