Frequently Asked Questions
What is a normal blood pressure reading?
A normal blood pressure is under 120/80 mmHg. The top number (systolic) should be below 120 and the bottom number (diastolic) below 80. Readings in this range indicate healthy cardiovascular function. Regular exercise, a low-sodium diet, and avoiding tobacco all help maintain normal blood pressure long-term.
What is the difference between systolic and diastolic pressure?
Systolic pressure is the top number — it measures force on artery walls when your heart beats. Diastolic is the bottom number, measuring pressure when the heart rests between beats. Both numbers are equally important. A reading of 120/80 mmHg means 120 systolic and 80 diastolic.
At what point should I be concerned about high blood pressure?
Consult a doctor if readings consistently fall in Stage 1 hypertension (130–139/80–89 mmHg) or higher. Stage 2 (140+/90+) usually requires medication. A hypertensive crisis above 180/120 mmHg is a medical emergency — seek immediate care if accompanied by chest pain, severe headache, or vision changes.
Can blood pressure vary throughout the day?
Yes, blood pressure naturally fluctuates throughout the day. It is typically lowest during sleep and peaks in the early morning, a pattern called morning surge. Physical activity, stress, caffeine, and even talking can temporarily raise it. For reliable readings, measure at the same time each morning before eating or taking medication.
How can I lower my blood pressure naturally?
Natural approaches include regular aerobic exercise (150 minutes per week), reducing sodium to under 2,300 mg daily, eating a DASH diet rich in potassium and magnesium, limiting alcohol, quitting smoking, managing stress through meditation or deep breathing, and maintaining a healthy weight. Even modest changes can lower pressure by 5–10 mmHg.
