Understanding Your Blood Pressure in 3 Minutes
By: Noor Arshad, MD., Internal Medicine Resident
What Do the Two Numbers Mean?
- Blood pressure readings consist of two numbers, such as 120/80:
- Top Number (Systolic): This indicates the pressure in your arteries when your heart beats and pumps blood.
- Bottom Number (Diastolic): This reflects the pressure in your arteries when your heart rests between beats.
What is a Normal Blood Pressure?
- Normal: Less than 120/80
- High: 130/80 or higher
- Emergency: 180/120 or higher (Seek immediate medical help if you experience symptoms)
Why Does Blood Pressure Matter? High blood pressure is a significant health concern as it can lead to serious conditions like heart attacks, strokes, kidney disease, and vision problems—often without noticeable symptoms.
What Affects Your Blood Pressure? Several factors can influence your blood pressure, including:
- Stress
- High salt intake
- Poor sleep quality
- Pain
- Missed medications

How to Check Blood Pressure at Home
- Sit and relax for 5 minutes, ensuring your feet are flat on the floor and your arm is at heart level.
- Avoid talking during the measurement.

When Should You Worry?
- Call your doctor if your blood pressure consistently remains above 140/90.
- Go to the emergency room if you have a reading of 180/120 along with symptoms.
