Blood pressure is the force of your blood pushing against the walls of your arteries. Each heartbeat pumps blood into these arteries, creating pressure. This pressure fluctuates throughout the day.
Understanding Blood Pressure Measurement
Blood pressure is measured in millimeters of mercury (mmHg) and expressed as two numbers:
- Systolic pressure: The higher number, representing the pressure when your heart beats and pumps blood.
- Diastolic pressure: The lower number, representing the pressure when your heart rests between beats.
A reading is typically given as systolic/diastolic (e.g., 120/80 mmHg).
Normal Blood Pressure
While the definition of "normal" can vary slightly, a generally accepted range is below 120/80 mmHg. [Source: Multiple sources including Cleveland Clinic, American Heart Association, and NIH.]
High Blood Pressure (Hypertension)
High blood pressure, or hypertension, occurs when blood pressure consistently remains elevated at 130/80 mmHg or higher. This places increased strain on your heart and blood vessels, raising the risk of serious health problems. [Source: NHLBI, NIH, Mayo Clinic, WHO]
- Consequences of Hypertension: High blood pressure increases the risk of heart disease, stroke, heart failure, and kidney disease. [Source: CDC, Mayo Clinic, FDA]
Measuring Your Blood Pressure: The only way to know your blood pressure is to have it measured. Regular monitoring is crucial, especially for those at risk of hypertension. [Source: American Heart Association]
In Summary
Blood pressure is a vital sign reflecting the force of blood against artery walls. Maintaining healthy blood pressure is essential for preventing numerous cardiovascular diseases. Regular monitoring and lifestyle adjustments are key to managing blood pressure effectively.
