Measuring blood pressure seems simple, but most people do it incorrectly — leading to unnecessary worry, urgent hospital visits, or misdiagnoses. This guide explains how blood pressure works, how to measure it properly, when to worry, and which habits and foods help keep it under control.
What is bl00d pressure?
Blood pressure is the force of blood pushing against artery walls each time the heart beats.
- Systolic (max): when the heart contracts.
- Diastolic (min): when the heart relaxes.
- Healthy blood pressure is generally below 120/80 mmHg.
When is it high?
Hypertension is diagnosed if readings consistently exceed:
- 140 mmHg systolic
- 90 mmHg diastolic
One high reading doesn’t automatically mean hypertension; blood pressure naturally fluctuates with activity, stress, or diet.
How to measure at home correctly
Prepare: Don’t eat, smoke, drink coffee/mate, or talk 45 minutes prior. Be calm and empty your bladder.
Posture: Sit with back supported, arm at heart level on a table, legs uncrossed, arm free of tight clothing.
Cuff placement: Hose inside the arm, not too tight/loose, 2 finger widths from elbow crease.
Recording: Take readings morning and night, while seated and resting, for 5–7 consecutive days. Share results with your doctor.
When high readings aren’t emergencies:
