Frequently asked questions
What is considered normal blood pressure?
According to the American Heart Association, normal blood pressure is less than 120 mmHg systolic AND less than 80 mmHg diastolic (less than 120/80 mmHg).
When should I check my blood pressure?
Check at the same times each day — morning before medications and evening after rest. Sit quietly for 5 minutes beforehand, keep your feet flat on the floor, and don't smoke, drink caffeine, or exercise within 30 minutes of measuring.
How can I lower my blood pressure naturally?
The DASH diet (rich in fruits, vegetables, low-fat dairy, low sodium), regular aerobic exercise (150 minutes/week), limiting alcohol, not smoking, managing stress, and maintaining a healthy weight are all proven approaches.
What do the two blood pressure numbers mean?
Systolic (top number) measures the pressure in your arteries when your heart beats. Diastolic (bottom number) measures the pressure when your heart rests between beats. Both numbers matter for assessing cardiovascular risk.
How accurate are home blood pressure monitors?
Validated home monitors (upper-arm cuff style) are generally as accurate as office measurements when used correctly. Wrist monitors are less reliable. Look for the American Medical Association's VALIDATED list or devices certified by the British Hypertension Society.
