Do you know when and how to measure blood pressure? Discover everything!

Hypertension is a very common disease that affects millions of people around the globe. However, it is estimated that half of these people are unaware that they have high blood pressure. Why? It’s simple: since it’s a disease that doesn’t cause pain and there are no immediate symptoms, if regular measurements are not taken, high blood pressure is not diagnosed – and consequently, not treated.

In silence, high blood pressure wears down the human body and increases the likelihood of developing other coronary diseases, such as strokes or heart attacks. Therefore, even without visible symptoms, it is extremely important to maintain a preventive attitude towards blood pressure by adopting healthy lifestyle habits and engaging in physical exercise. But after all, what is blood pressure?

What is blood pressure?

Throughout the 24 hours of our day, the heart never stops. Its function is, with each heartbeat, to pump blood so that it circulates through the arteries, carrying oxygen and nutrients to all cells of our body. The pressure at which blood circulates within the arteries is called Blood Pressure. It is this pressure that ensures that blood circulates properly throughout the body.

What are the normal values ​​of blood pressure?

The measurement of Blood Pressure is based on two parameters: the maximum – or systolic – blood pressure, and the minimum – or diastolic – blood pressure.

The Minimum Arterial Pressure corresponds to the pressure exerted on the walls of the arteries during the heart’s rest between heartbeats. The Maximum Arterial Pressure is the one exerted on the walls of the arteries with each heartbeat.

Normal Blood Pessure is considered when the maximum blood pressure is between 12 and 13 mmHg, and the minimum blood pressure is between 8 and 8,5 mmHg.

Variations in Blood Pressure

And when the values ​​do not correspond to the normal parameters?

When the measured values are significantly below or above the considered normal values, it could be one of two scenarios:


In these cases, what happens is that the blood flow doesn’t have enough force to reach the entire body and transport oxygen and nutrients to all cells, affecting the proper functioning of some organs – leading to drops in blood pressure. This condition can be associated with a range of causes, including heart failure, dehydration, blood loss, excessive medication, nervous system disorders, among others. It’s also a recurring issue during pregnancy. In most cases, drops in blood pressure are accompanied by symptoms such as dizziness, blurred vision, and fainting.

Hypotension is Low Blood Pressure when the measured values ​​are below 9/5 mmHg. The treatment for hypotension is based on medication prescription and the adoption of a healthier lifestyle, allowing blood pressure to rise to normal values.


Hypertension is High Blood Pressure when the measured values ​​are above 14/9 mmHg, and it’s a condition that affects a large number of people worldwide.

At its root, it can have various causes: infections, kidney diseases, diabetes, unhealthy lifestyle habits, obesity, among others. There are two types of hypertension: primary, which increases with age and is not associated with any specific cause, and secondary, which is caused by an underlying condition and tends to appear suddenly, being more common in younger ages.

In most cases, hypertension is asymptomatic. The treatment is based on medication prescription and the adoption of a healthier lifestyle, allowing blood pressure to lower to normal values.

Is it important to measure blood pressure regularly?

For a healthy individual, there’s no need to measure blood pressure very regularly. Blood pressure should be measured annually, along with other routine clinical examinations recommended for adults. However, individuals with diabetes or with renal, cardiac, or neurological pathologies should do it more regularly, according to the doctor’s instructions.

Unless requested by a healthcare professional, there is no benefit in very frequent blood pressure measurements. On the contrary, it can be a source of anxiety and worry.
Nevertheless, since hypo and hypertension are diseases that do not cause pain, diagnosing them in a timely manner is crucial to ensure early and effective intervention. So, maintain a preventive attitude and monitor your blood pressure.

The “White Coat Effect”

Surely it has happened to you – or you know someone to whom it has happened – to go to the doctor, measure blood pressure, and the values are high. These cases are known as the ‘White Coat Effect,’ and what happens is that the patient has isolated high blood pressure when they are in the doctor’s office, but outside of the office, their blood pressure values are always normal. In many cases, when hypertension is detected during the appointment, unnecessary medication is prescribed, which then brings other implications in the patient’s daily life.

Therefore, to avoid unnecessary medication administration, doctors have been avoiding blood pressure measurement during appointments and advising that it be done at home, in a calm and quiet environment, with a blood pressure monitor. If the values recorded at home are indeed abnormal, then the doctor may prescribe the most appropriate medication. But how to measure blood pressure correctly at home?

How to measure blood pressure correctly?

If you are going to measure blood pressure at home using a blood pressure monitor, we provide you with an Essential Guide on how to do it. First of all, when should the measurement be taken?

  • In the morning, take the measurement upon waking up, before any medication and on an empty stomach.
  • At night, take the measurement at least two hours after dinner and before going to bed.

Before the Measurement

  • Preferably, take the measurement directly on the skin, without clothing on the arm area.
  • Sit comfortably with your back supported and in a relaxed and rested position.
  • Do not measure blood pressure if you are experiencing any emotional disturbance or physical alteration (such as needing to use the bathroom, for example).
  • Do not smoke or drink coffee or other stimulant beverages at least one hour before taking the measurement.

How to make the correct measurement with a blood pressure monitor?

To make the correct measurement of blood pressure using a blood pressure monitor with an arm cuff, you should:

  • Place the cuff (which should be suitable for the diameter of your arm) about 2 to 3 centimeters above the elbow.
  • Support the arm so that the cuff is at the level of the heart and never below it.
  • Press the button to start the measurement on the device and remain still and relaxed throughout the process until the device displays the final readings. Avoid talking or crossing your legs during the process.

For accurate and reliable readings, it’s ideal to take three measurements spaced one to two minutes apart. The first measurement should not be taken into account, and only the last two should be recorded for monitoring purposes.

Is your Blood Pressure outside the normal range for the first time?

If you measured your blood pressure following our tips and the readings are outside the normal range, it’s important to note that a single measurement is not enough to diagnose hypo or hypertension. After detecting abnormal readings, you should adopt a preventive approach and measure your blood pressure more frequently in the coming days. If the anormal readings persist, consult your doctor and follow their advice.

Types of Blood Pressure Monitors

Blood Pressure Monitors can be of two types: arm cuff – or brachial cuff – and wrist cuff. These two types differ mainly in how they are used and where they are placed to take the measurement.


It is placed on the arm, usually at the level of the heart. It is more accurate and more recommended for reliable measurements. It is more comfortable, especially if the person has circulation issues in the hands or wrist.


It is placed on the wrist and is more compact and portable. It is more convenient for travel or occasional use, but it can be less accurate, especially if not used correctly or if the wrist isn’t in the proper position during measurement.

What are the best Blood Pressure Monitors?

Generally, arm blood pressure monitors are more reliable. So if you’re buying a new blood pressure monitor, choose an arm cuff model.
