Understanding Blood Pressure

Let’s begin by getting clear about what exactly is blood pressure?

What is Blood Pressure?

Blood pressure is the force exerted by circulating blood against the walls of blood vessels. It is measured in millimeters of mercury (mmHg) and recorded as two numbers: systolic (pressure during heartbeats) over diastolic (pressure between heartbeats).

Types of Blood Pressure

Normal Blood Pressure: Systolic less than 120 mmHg and diastolic less than 80 mmHg.

Elevated Blood Pressure: Systolic between 120-129 mmHg and diastolic less than 80 mmHg.

Hypertension Stage 1: Systolic between 130-139 mmHg or diastolic between 80-89 mmHg.

Hypertension Stage 2: Systolic at least 140 mmHg or diastolic at least 90 mmHg.

Hypertensive Crisis: Systolic over 180 mmHg and/or diastolic over 120 mmHg, requiring immediate medical attention.

Importance of Blood Pressure Management

Maintaining the right blood pressure is essential to prevent conditions such as heart disease, stroke and kidney damage which nobody wants of course. Uncontrolled hypertension can lead to severe health complications and even death.

How Breathing Affects Blood Pressure

In this section, we’re going to discover how surprising powerful an effect breathing has on your blood pressure.

The Physiology of Breathing

Breathing involves the intake of oxygen and release of carbon dioxide by the lungs. This process is controlled by muscles - namely the diaphragm (at the bottom of your lungs) and intercostal muscles (these are in between your ribs).

Proper breathing ensures adequate oxygen to the body and efficient removal of waste gases.

Connection Between Breathing and Blood Pressure

When you breath deeply and slowly, you activate a part of your nervous system called the ‘parasympathetic nervous system’. This promoting relaxation and reduces your heart rate. This, in turn, can lower blood pressure by decreasing the resistance in blood vessels.

Benefits of Breathing Exercises

Let’s find out the beneficial effects of doing breathing techniques and exercises on your blood pressure, and which ones could be best for you.

Breathing Techniques for Reducing Stress

Breathing exercises are known to reduce stress levels by calming the mind and body. Lower stress can directly impact blood pressure, as chronic stress is a known risk factor for hypertension.

Breathing to Enhance Heart Health

Consistent practice of breathing exercises can improve heart (cardiovascular) function by reducing the strain on the heart and promoting better circulation.

Breathing Exercises Improve Mental Clarity

Regular breathing exercises increase oxygen flow to the brain, enhancing mental clarity and cognitive function, which can be beneficial for overall well-being. So not only could these exercises lower your blood pressure, they can help you to feel more focused and reduce brain fog.

Popular Breathing Techniques

Let’s learn the most popular breathing exercises, known to reduce blood pressure.

Diaphragmatic Breathing

Also known as abdominal or belly breathing, this technique involves breathing deeply into the lower part of your lungs (diaphragm) rather than shallowly into the chest. It promotes full oxygen exchange and can help lower heart rate and stabilise blood pressure.

4-7-8 Breathing Technique

This method, popularized by Dr. Andrew Weil, involves inhaling for 4 seconds, holding the breath for 7 seconds, and exhaling for 8 seconds. It helps to reduce anxiety and promote relaxation.

Alternate Nostril Breathing

This yoga technique involves inhaling through one nostril while blocking the other, then switching. It balances the body's energies and calms the nervous system.

Box Breathing

Also known as square breathing, this method involves inhaling, holding, exhaling, and holding again, each for 4 seconds. It can reduce stress and improve focus. The exact number of seconds can be adjust so it’s comfortable for you.

Resonant Breathing

Also called coherent breathing, this technique involves breathing at a rate of 5-6 breaths per minute. It maximizes heart rate variability and promotes relaxation.

How to Practice Breathing Exercises

In this section, I explain in further detail how to do these exercises.

Creating a Conducive Environment

Choose a quiet, comfortable space, free from distractions if possible. Especially the first time you do this. With experience, you can do these in any environment.

You may sit or lie down for these exercises, ensuring your posture allows for deep, unrestricted breathing. Avoid slouching as this restricts your lungs.

Step-by-Step Instructions

1. Diaphragmatic Breathing:

- Place one hand on your chest and the other on your abdomen.

- Inhale deeply through your nose, allowing your abdomen to rise while keeping your chest still.

- Exhale slowly through your mouth, feeling your abdomen fall.

2. 4-7-8 Breathing:

- Inhale quietly through your nose for 4 seconds.

- Hold your breath for 7 seconds.

- Exhale completely through your mouth for 8 seconds.

3. Alternate Nostril Breathing:

- Use your right thumb to close your right nostril.

- Inhale deeply through your left nostril.

- Close your left nostril with your right ring finger and exhale through the right nostril.

- Continue alternating for several minutes.

4. Box Breathing:

- Inhale through your nose for 4 seconds.

- Hold your breath for 4 seconds.

- Exhale through your mouth for 4 seconds.

- Hold your breath for 4 seconds.

5. Resonant Breathing:

- Breathe in for 5 seconds.

- Breathe out for 5 seconds.

- Continue this pattern to maintain a steady, calming rhythm.

Consistency and Routine

Incorporate breathing exercises into your daily routine. Practicing for just 5-10 minutes a day can yield significant benefits over time. Aim to practice at the same time each day to develop a habit.

Incorporating Breathing Exercises into Daily Life

Morning Routine

Start your day with a few minutes of breathing exercises to set a calm tone for the day. This can help reduce morning stress and prepare your body and mind for the tasks ahead.

During Work

Take short breaks during your workday to practice breathing exercises. This can help manage work-related stress and maintain focus and productivity. I like to do these exercises before meals, too.

Before Sleep

Practicing breathing exercises before bed can promote relaxation and improve sleep quality, helping you wake up refreshed and ready for the day. It’s a wonderful time to do a breathing exercise.

Scientific Evidence

Studies on Breathing Exercises and Blood Pressure

As Harvard states, a review article published on 25 January 2023 in Frontiers in Physiology examined the impact of various breathing exercises on individuals with high blood pressure. Among the 20 studies reviewed, 17 reported reductions in blood pressure. The studies differed significantly in terms of duration, frequency, and types of breathing exercises performed, making it challenging to recommend a specific regimen.

However, experts suggest that any form of breathing practice could be beneficial. Professionals usually provide patients with a range of options, saying, "Here are several ways you can start a breathing practice. Which one seems best for you?" This blog includes some breathing techniques to help manage your blood pressure.
