Anyone who’s advised to start tracking their blood pressure more often is soon taken down a rabbit hole of questions.
Knowing you have high blood pressure is stressful enough as it is. Naturally, you’ll want to ensure you follow the correct method to check your levels.
So, today we’ll highlight ten essential facts about blood pressure readings and bust common myths to get the truth on the table.
How often you should measure your blood pressure depends on a couple of factors:
Those who are newly diagnosed with hypertension, for example, are advised to take three readings in the morning and do the same in the evening to calculate an average.
For those who aren’t newly diagnosed but are known to be at particular risk of cardiac issues, it may be necessary to continue to take readings multiple times a day.
In most cases, people don’t measure their blood pressure often enough.

Cuff on. Cuff off. And repeat.
Traditional blood pressure readings get old, fast. It’s tempting to chat with someone to pass the time while you’re waiting for the machine to finish the measurement. But this is a mistake.
Talking — either in-person or on the phone — can add 10 points to your blood pressure reading. Instead, relax and try to enjoy some quiet time without engaging in conversation.
Most people know they should measure their blood pressure while they are seated. However, that doesn’t tell the full story. Think you can get an accurate measurement as soon as you sit down?
An unavoidable fact about blood pressure readings using the traditional method is that a little patience is required to do them right.
Aim to sit down for five minutes before you put the cuff on and turn on the machine.
Trying to find the right-sized cuff to fit your arm can be a tricky task. No wonder people often continue with a cuff that’s too loose or too tight.
You’ll need to measure your arm circumference to figure out the ideal cuff size. Here is a guidance chart if you’re not sure:
|Arm Circumference||Recommended Cuff Size|
|cm||in||width x length in cm|
|22 – 26||8.7 – 10.2||12 x 22 (small adult)|
|27 – 34||10.6 – 13.4||16 x 30 (adult)|
|35 – 44||13.8 – 17.3||16 x 36 (large adult)|
|45 – 52||17.7 – 20.5||16 x 42 (extra-large adult)|
A surprising number of people think that measuring their blood pressure with the cuff over their shirt is okay. Alas, it’s a big no-no!
Committing this error can increase the reading by anywhere from 5 to 50 points.
Do you usually cross your legs when you sit down? Hopefully not.
A little-known fact is that crossing your legs during a BP reading risks causing the reading to rise by up to 8 points.
It’s best to keep your feet level on the ground with your back well supported.
Who would have thought?
Holding in your pee when you need to go isn’t a healthy habit. We all know that. But the impact it has on blood pressure measurements isn’t widely known.

This is another common myth to bust.
Ensure the cuff is in line with your heart every time you check your blood pressure.
The cuff needs to be on the correct place on the upper arm, ~2.5 cm above the inner bend in the arm at the elbow.
The cuff is too high on your arm? You’ll get a lower reading.
Is the cuff is too low? You may get a reading that’s up to 10 points higher than your true blood pressure level.
Solve this problem by resting your arm on a table or chair at the appropriate height.
While your first blood pressure measurement may take place in a clinician’s office, the reality is you can’t visit your doctor every day.
There is a greater risk of invalid results when you check your blood pressure at home without professional guidance.
Nonetheless, if you follow the correct method (as shown in the image above), then you should be able to rely on the reading.
Earlier, we said that some people may need to measure their blood pressure five times or more each day.
Realistically, that’s over 15 minutes a day, considering the breaks in between each reading. Even checking your blood pressure once per day using the standard cuff method can be time-consuming when you factor in taking the equipment out, getting everything set up, then putting it all away again.
Additionally, having a system to log your readings can take time and effort. Whether you write them down on a notepad or use a spreadsheet, it creates another task to remember throughout your busy day.
