The home BP guide

Home blood pressure basics

Your home readings help your healthcare provider see a pattern over time. Ask them how often to check and when to review your readings.

How to measure at home

  1. Use the right monitor. Choose a validated automated upper-arm monitor with a cuff that fits. Your pharmacist or healthcare provider can help.
  2. Prepare. Avoid exercise, caffeine and smoking for at least 30 minutes beforehand. Empty your bladder.
  3. Sit quietly for 5 minutes. Support your back, keep your feet flat and leave your legs uncrossed.
  4. Position your arm. Place the cuff on your bare upper arm as the monitor instructions show. Support your arm with the middle of the cuff at heart level.
  5. Take and record your readings. Stay still and do not talk. Take two readings one minute apart and record both, unless your provider has given a different plan.

Ask your provider about measurement timing in relation to medicines and meals. Take medications as prescribed.

What do the two numbers mean?

Top number · systolic

When your heart pumps

The pressure in your arteries as your heart contracts.

Bottom number · diastolic

Between heartbeats

The pressure in your arteries as your heart relaxes.

Blood pressure is measured in millimetres of mercury (mmHg). High blood pressure often causes no symptoms. Over time, it can harm the heart, brain and kidneys.

Ask your healthcare provider what your readings mean and what home blood pressure goal or range is appropriate for you. Do not change your medication without advice from your prescriber.

Everyday habits

Move regularly

Build activity into your day in ways that suit your health. Ask your provider for advice if you are unsure where to start.

Drink less alcohol

If you drink, reducing the amount can help lower blood pressure.

Get help to quit tobacco

Your healthcare provider or pharmacist can help you find support and treatment options.

Make time for rest

Keep regular sleep habits and find manageable ways to reduce stress.
