“For breath is life, and if you breathe well you will live long on earth.” ~Sanskrit proverb
Breath is essential to life. It is the first thing we do when we are born and the last thing we do when we leave. In between that time, we take about half a billion breaths. What we may not realize is that the mind, body, and breath are intimately connected and can influence each other. Our breathing is influenced by our thoughts, and our thoughts and physiology can be influenced by our breath. Learning to breathe consciously and with awareness is the fourth limb of yoga, and it can be a valuable tool in helping to restore balance in the mind and body.
Researchers have documented the benefits of a regular practice of simple, deep breathing (1,2,6), which include:
- Reduced anxiety and depression
- Lower/stabilized blood pressure
- Increased energy levels
- Muscle relaxation
- Decreased feelings of stress and overwhelm
In the medical community, there is a growing appreciation for the positive impact that deep breathing can have on the physiology, both in the mind and the body. According to the research, many of these beneficial effects can be attributed to reducing the stress response in the body. To understand how this works, let’s look at the stress response in more detail.
Pranayama as a Tool to Counter Stress
When you experience stressful thoughts, your sympathetic nervous system triggers the body’s ancient fight-or-flight response, giving you a burst of energy to respond to the perceived danger. Your breathing becomes shallow and rapid, and you primarily breathe from the chest and not the lower lungs. This can make you feel short of breath, which is a common symptom when you feel anxious or frustrated. At the same time, your body produces a surge of hormones such as cortisol and epinephrine (also known as adrenaline), which increase your blood pressure and pulse rate and put you in a revved up state of high alert.
With deep breathing, you can reverse these symptoms instantly and create a sense of calm in your mind and body. When you breathe deeply and slowly, you activate the parasympathetic nervous system, which reverses the stress response in your body. Deep breathing stimulates the main nerve in the parasympathetic nervous system—the vagus nerve—slowing down your heart rate, lowering your blood pressure, and calming your body and mind.
In addition, with deep breathing, you engage the abdominal muscles and diaphragm instead of the muscles in the upper chest and neck. This conditioning of the respiratory muscles results in improved efficiency of oxygen exchange with every breath by allowing more air exchange to occur in the lower lungs. It also reduces strain on the muscles of the neck and upper chest, allowing these muscles to relax. In short, deep breathing is more relaxing and efficient, allowing higher volumes of oxygen to reach the body’s cells and tissues.
As well as reversing the physical stress response in the body, deep breathing can help calm and slow down the emotional turbulence in the mind. Breathing can have an immediate effect on diffusing emotional energy so there is less reactivity to our emotions.
4 Deep Breathing Techniques
Beyond the practice of simple deep breathing, the ancient yogis described different types of rhythmic deep breathing techniques that can have differing effects on the mind and body. In fact, many studies document the beneficial effects of yogic breathing in treating depression, anxiety, PTSD (posttraumatic stress disorder), COPD (chronic obstructive pulmonary disease), and asthma. (3,4,5) There are also theories that support the notion that by slowing down and controlling the breath, we can improve our longevity.(3)
The basis for all deep breathing practices originates in the science of yoga, specifically the branch of yoga known as pranayama. The word pranayama is derived from two Sanskrit words: prana (life force) and yama (control). By controlling the breath, you can influence every aspect of your life. You can train yourself to breathe in a way that has a positive influence on your health.
Each of the following simple yogic breathing techniques has specific effects on the mind-body physiology.
Complete Belly Breath: With one hand on your belly, relax your abdominal muscles, and slowly inhale through the nose, bringing air into the bottom of your lungs. You should feel your abdomen rise. This expands the lower parts of the lungs. Continue to inhale as your rib cage expands outward, and finally, the collar bones rise. At the peak of the inhalation, pause for a moment, then exhale gently from the top of your lungs to the bottom. At the end of exhalation, contract your abdominal muscles slightly to push residual air out of the bottom of your lungs.
Alternate Nostril Breathing: When you are feeling anxious or ungrounded, practice Alternate Nostril Breathing, known as Nadi Shodhana in the yogic tradition. This will immediately help you feel calmer.
- Hold your right thumb over your right nostril and inhale deeply through your left nostril.
- At the peak of your inhalation, close off your left nostril with your fourth finger, lift your right thumb, and then exhale smoothly through your right nostril.
- After a full exhalation, inhale through the right nostril, closing it off with your right thumb at the peak of your inhalation, lift your fourth finger and exhale smoothly through your left nostril.
- Continue with this practice for 3 to 5 minutes, alternating your breathing through each nostril. Your breathing should be effortless, with your mind gently observing the inflow and outflow of breath.
Ocean’s Breath: When you feel angry, irritated, or frustrated, try a cooling pranayama such as Ocean’s Breath, or Ujjayi (pronounced oo-jai). This will immediately soothe and settle your mind.
- Take an inhalation that is slightly deeper than normal. With your mouth closed, exhale through your nose while constricting your throat muscles. If you are doing this correctly, you should sound like waves on the ocean.
- Another way to get the hang of this practice is to try exhaling the sound “haaaaah” with your mouth open. Now make a similar sound with your mouth closed, feeling the outflow of air through your nasal passages.
- Once you have mastered this on the outflow, use the same method for the inflow breath, gently constricting your throat as you inhale.
Energizing Breath: When you are feeling blue or sluggish, try Energizing Breath or Bhastrika. This will give you an immediate surge of energy and invigorate your mind.
- Begin by relaxing your shoulders and take a few deep, full breaths from your abdomen.
- Now start exhaling forcefully through your nose, followed by forceful, deep inhalations at the rate of one second per cycle. Your breathing is entirely from your diaphragm, keeping your head, neck, shoulders, and chest relatively still while your belly moves in and out.
- Start by doing a round of ten breaths, then breathe naturally and notice the sensations in your body. After 15 to 30 seconds, begin the next round with 20 breaths. Finally, after pausing for another 30 seconds, complete a third round of 30 breaths. Beginners are advised to take a break between rounds.
Although Bhastrika is a safe practice, stay tuned in to your body during the process. If you feel light-headed or very uncomfortable, stop for a few moments before resuming in a less intense manner.
Contraindications: Do not practice Bhastrika if you are pregnant or have uncontrolled hypertension, epilepsy/seizures, panic disorder, hernia, gastric ulcer, glaucoma, or vertigo. Use caution if there is an underlying lung disease.
A regular daily practice of deep breathing is one of the best tools for improving your health and well-being. Performing one of these breath techniques twice daily for only three to five minutes can produce long-term benefits. You can also use them any time you are feeling stressed or notice that your breathing has become constricted. By training your body with a regular practice of deep breathing, you will begin to breathe more effectively even without concentrating on it.
