How Deep Breathing Exercises Support a Strong Heart
20 September 2024
Proper breathing plays a crucial role in maintaining the health and functionality of our lungs, heart, and other vital organs. However, many of us tend to breathe shallowly, utilizing only a small portion of our lung capacity. This can result in various health problems, including shortness of breath, anxiety, and stress. Shallow breathing can also elevate heart rate and blood pressure, placing unnecessary strain on the cardiovascular system.
In contrast, deep breathing exercises can expand lung capacity and enhance the performance of both the respiratory and cardiovascular systems. These exercises also help alleviate stress and anxiety, promoting a sense of calm and relaxation.
Deep breathing involves slow, deep breaths that engage the diaphragm to draw air fully into the lungs. This method of breathing activates the parasympathetic nervous system, which helps relax the body and soothe the mind.
Incorporating deep breathing exercises into your routine can have significant benefits for both physical and mental health, while also supporting heart health. In this blog, we’ll delve into the advantages of deep breathing exercises for your heart and share simple techniques you can easily add to your daily routine. Let’s take a deep breath and explore how these exercises can help keep your heart healthy.
Does Breathing Play a Role in Heart Health?
The respiratory and cardiovascular systems are interconnected through the lungs, which sit between the right and left sides of the circulatory system. Because of this, breathing directly influences cardiovascular function.
Although circulation and respiration are often treated as separate ‘systems’ in academic and medical disciplines, shortness of breath is a primary symptom of congestive heart failure.
Likewise, individuals with structural lung diseases frequently develop pulmonary hypertension, which can lead to right-sided heart failure. Serious, right?
So, how does deep, mindful breathing fit into this? And how can something so simple be beneficial?
Breathing can have therapeutic effects, as seen in everything from the common advice to “take a deep breath” to religious practices and scientific research. Studies show that structured deep breathing exercises can reduce anxiety, manage pain, regulate blood glucose levels, and lower blood pressure.
The Importance of Breathing Exercises
You inhale and exhale with your diaphragm handling about 80% of the work, filling your lungs with a mix of oxygen and other gases, and then expelling the waste gases.
Like a door that can spring open, our lungs are naturally elastic. However, conditions like asthma and COPD (Chronic Obstructive Pulmonary Disease) cause the lungs to gradually lose this elasticity. As a result, they can no longer return to their original state, causing air to become trapped.
Over time, stale air builds up in the lungs, reducing the space for the diaphragm to contract and bring in fresh oxygen. When the diaphragm isn’t functioning properly, the body compensates by using muscles in the neck, back, and chest for breathing.
This leads to lower oxygen levels and decreased physical endurance. Regular breathing exercises can help clear the trapped air from the lungs, boost oxygen intake, and restore the diaphragm’s role in efficient breathing.
How Does This Benefit Your Heart?
It’s not just general breathing, but specific breathing exercises and techniques that have been proven to benefit your heart.
-
- Deep breathing can slow down your heart rate.
- Slow breathing helps lower blood pressure.
- It also reduces symptoms of anxiety and depression, both of which can put strain on the heart.
- Breathing at a slow rate of 6 breaths per minute has been shown to improve blood circulation.
Boost Your Heart Health with These Breathing Techniques
Yoga is a holistic practice that combines physical postures and breathing exercises to enhance strength, balance, flexibility, and relaxation. It encompasses various styles such as hatha, ashtanga, and anusara, each emphasizing different aspects like strength training or mindfulness.

The Core of Vital Living Yoga, particularly Pranayama, can significantly impact cardiovascular health. Just a few minutes of Pranayama practice can lower heart rate and resting blood pressure. Over time, this can lead to a lasting reduction in both, easing the burden on the heart. But what exactly is Pranayama?
The term Pranayama is derived from two Sanskrit words: ‘prana’ meaning ‘life force’ or ‘vital energy’, and ‘ayama’ meaning ‘extension’ or ‘expansion’. Therefore, Pranayama refers to the ‘expansion of life force’.
To practice, block your left nostril with your finger and inhale slowly through the right nostril for 10 seconds. Then, close the right nostril and exhale through the left nostril for 10 seconds. This process involves alternating nostrils for inhalation and exhalation. - Power Breathing
Power breathing exercises can be performed virtually anywhere—whether at your desk, on public transport, in the car, or at home. These exercises help cleanse the sinuses, boost energy, enhance endurance, and improve the efficiency of the nervous and digestive systems. They also provide pain relief and sharpen concentration. As your body relaxes, your blood vessels expand, which improves circulation and lowers blood pressure. - Belly Breathing or Diaphragmatic Breathing
To practice this technique, breathe in through your nose while placing your hands on your stomach to feel it rise and fall. Exhale through your mouth for twice as long as your inhalation. Keep your shoulders and neck relaxed, and use your diaphragm to help fill and empty your lungs. This breathing method enhances blood circulation and slows down your breathing rate. - Yoga Nidra Meditation
Yoga Nidra, while akin to meditation, has some distinct differences. The primary aim of Yoga Nidra is to enter a profound state of conscious sleep, a deeper level of rest where you remain aware. This practice involves moving through stages from wakefulness to dreaming, and then from dreaming to a state of non-dreaming, all while maintaining awareness — effectively bridging the unconscious and conscious realms.
Yoga Nidra is particularly beneficial for reducing blood pressure and easing the cardiovascular strain for individuals with heart conditions. Research has shown that Yoga Nidra can even reverse severe heart diseases like ischemic heart disease (IHD). - Kapalabhati – fast breathing
It involves a vigorous, forceful exhalation followed by a passive inhalation. Previous studies have shown that altering the breathing pattern during Kapalabhati results in a decrease in cardiac vagal tone, which is a marker of emotional stress and fatigue.

Best Times to Practice Breathing Techniques
The early morning hours are ideal for this practice. The air is crisp, and the atmosphere is pleasant. Even if you live in the city, there’s a sense of purity at this time of day.
Start your day on a positive note by incorporating breathing exercises or yogic breathing into your routine to invigorate your spirit.
Conclusion
Incorporating deep breathing exercises into your daily routine can greatly benefit your heart health. Regular practice can enhance lung capacity, reduce stress and anxiety, lower inflammation, and improve blood flow, all of which contribute to a healthier heart.
Start gradually and avoid deep breathing exercises when you’re already out of breath. Aim to practice for 5-10 minutes each day, and increase the duration as you become more accustomed to the exercises.
If you find the initial sessions challenging, don’t be discouraged; with time and practice, deep breathing will become more natural. By focusing on your breathing and caring for your heart, you can support your overall health and well-being.
