The Fourth Branch of Yoga: Pranayama (Toning down Agitation through Breath Practice)

by Ram

Irises in Monet's Garden by Claude Monet

In the Sadhana Pada of the Yoga Sutras by Patanjali we are introduced to the concept of Ashtanga Yoga (Ashta=eight; Anga=limbs), which refers to the eight-fold path/eight rungs/limbs/steps of yoga as described in the Raja Yoga section of the yoga philosophy. Its practice helps us to discriminate between ignorance and awareness and truth from illusion, which is the means for liberation or enlightenment. The first three limbs namely Yama, Niyama, and Asana, which I discussed in earlier posts help to prepare the body and mind for regulating the breath and achieving stillness.

The fourth limb in the Ashtanga series is Pranayama: Prana =life force, breath, wind, air, respiration, vital energy, and ayama = extend, stretch, draw out, regulate. Pranayama, a formal practice of regulating the breath, consists of techniques designed to gain mastery over the respiratory process while building a connection between the breath, the mind, and the intellect. The technique refers to a particular system of breath control involving three processes namely: puraka (inhalation), kumbhaka (retention), and rechaka (exhalation). When these three processes are balanced, there is union of the body and mind.

According to the Yoga Sutras, the practices of pranayama and asana are considered to be the highest form of purification and self-discipline for the mind and the body, respectively. Pranayama serves as the gateway to meditation and higher yogic practices, and the practice produces the actual physical sensation of heat, called tapas, or the inner fire of purification. It is believed that this heat is part of the process of purifying the nadis, the subtle nerve channels of the body. This allows a more healthful state to be experienced and allows the mind to become calm. As the yogi follows the proper rhythmic patterns of slow deep breathing, the patterns strengthen the respiratory system, soothe the nervous system, and reduce craving. As desires and cravings diminish, the mind is set free and becomes a fit vehicle for concentration. Thus, any individual who has a regular practice of pranayama is able remove the impurities of the body, the senses, and the mind through the power of breath regulation.

Pranayama not only pacifies and revitalizes a tired body, but it also calms, rejuvenates, and uplifts the mind, leading the individual into deeper state of meditation. There are several different forms of pranayama, however, several teachers caution that pranayama practice needs to be restricted only to experienced practitioners. There is some wisdom in being vigilant about the practice, for if done incorrectly it can lead to problems in the nervous system and psychological disturbances. But there are a few basic pranayama practices that are safe for nearly everyone, and we have discussed a few of them on our blog (see Pranayama for Everyone: Bhramari Breath and Balancing Your Nervous System with Your Breath). You can practice pranayama as an isolated standalone technique or integrate it into your daily yoga asana routine.

Thus, the first three limbs together with pranayama practice refine our personalities, helping us gain mastery over the body and develop an energetic awareness of ourselves, all of which help us to control our senses and our mind, and attain a higher state of consciousness. Several researchers have now reported that pranayama techniques are beneficial in treating a range of disorders, including:

• improving cardio-pulmonary functions 
• increasing autonomic functions 
• balancing the blood pressure 
• relieving symptoms of asthma 
• reducing physical and mental stress 

Additionally, pranayama practitioners report that this breathing practice helps in developing a steady mind, strong willpower, and sound judgment.

I consider pranayama as a “green therapy” because no harm is done to the environment, trees, or animals around us. All it requires is a place to be seated and your willpower, focus and concentration. While the requirements for this practice are minimal, the benefits are immense!

Friday Q&A: Breath Practices for Anxiety

Statue and Bird by Melina Meza

Q: I’ve been having bouts of anxiety lately, especially first thing in the morning after I wake up. Is there a short, simple practice that I can do before I get out of bed that will calm me down so I can start my day in a better emotional state?

A: There definitely are some simple breath practices that you can use in the morning before you get up as well as any time during your day that you may find very helpful! In his post How Your Breath Affects Your Nervous System, Baxter gives the scientific background about why breath practices are so effective. And I myself regularly use a simple breath practice to help me relax when I’m feeling stressed and to help me fall back to sleep if I awake in the night.

I discussed your question with Baxter, and together we came up with a list of three practices that you can choose from. In general, all three are different ways of lengthening your exhalation. Because your heart rate is naturally slower on your exhalation than on your inhalation, making your exhalation longer than your inhalation begins to slow down your overall heart rate, sending a message to your brain that everything is more peaceful and calm than it was five minutes ago. This message encourages your brain to support this shift by activating the Rest and Digest or Relaxation Response (see The Relaxation Response and Yoga), which will reduce your stress hormones, quiet your mind, and hopefully quell your anxiety. 

Try all three techniques and see which ones work best for you. When you are initially learning the practices, it is best to do them for shorter periods. But I recommend over time working your way up to ten-minute sessions because it seems to take about 7 or 8 minutes for the Relaxation Response to take full effect. However, in a pinch, even a minute or two of a simple breath practice can help head off an anxiety attack, so even a short session can be very beneficial.

Exhalation Pausing. The simplest breath practice you can do is to pause briefly at the end of each exhalation. You can do this practice in a seated position or even lying in bed, on your back with your head supported by a pillow. Start by practicing basic breath awareness. This means focusing your mind on how your breath moves in your body, perhaps on how your belly rises and falls with your breath or, if it’s easier, how your chest moves with your breath. You could also focus on the more subtle sensations, such as the feeling of your breath moving in and out or your nostrils or, if you prefer, the sound your breath makes in your body. I actually like to lie on my back with my hands on my belly because that makes it very easy for me to feel the movement in my abdomen.

Now you’re ready to try pausing at the end of your exhalation. When you reach the end of your next exhalation, simply add a beat or two—without straining—before moving on to your inhalation. Keep it relaxed and easy. And if the practice irritates you in any way, simply return to your natural breath.

If at any point you realize your attention has wandered from your breath (it will, of course), simply—and without self-judgment—bring your attention back to your breath.

Bhramari (Buzzing Bee) Breath. This breath practice, in which you make a buzzing sound as you exhale, naturally lengthens your exhalation. To practice a simple version of Bhramari, start by inhaling normally through your nose. Then, keeping your mouth closed, make a low- to medium-pitched humming sound in your throat as you exhale. As you make the buzzing sound—which should last the entire length of the exhalation—tune into the literal vibration of the sound waves in your throat and even in your skull and brain. After you complete your exhalation, inhale through your nose, and if you're comfortable, repeat the cycle. Try to make your transitions into and out of each humming exhalation as smooth as possible. See Pranayama for Everyone: Bhramari Breath for more information.

1:2 Breath. In this breath practice, you actually control the length of your inhalations and exhalations, and aim for a ratio of 1:2, for example, a one-second inhalation and a two-second exhalation or a two-second inhalation and a four-second exhalation. 

Before starting this practice, spend a little time observing your natural breath and mentally counting the length of your typical inhalations and exhalations. If your inhalation is longer than your exhalation, start by making them the same length by consciously slowing your exhalation. 

Once your inhalation and exhalation are equal, try gently increasing the length of your exhalation by releasing air more slowly. Keep your breathing relaxed so you are not straining, and if at any time you begin to feel agitated, simply return to your natural breath. As long as your breath feels smooth and relaxed, continue to gradually increase your exhalation bit by bit until it is twice as long (but no more than twice as long) as your inhalation. If the 1:2 ratio feels uncomfortable or if you're gasping on your next inhalation, return to a ratio that is more comfortable. You can gradually work up to the 1:2 ratio with practice. 

Another way to lengthen your exhalation to a 1:2 ratio is to use a gentle version of Ujjayi breathing for your exhalation only. To do this, breath in normally through your nose, with a relaxed feeling in your throat and vocal cords. Then, as you start to exhale, slightly constrict your throat, keeping it very gentle and relatively quiet. This action in your throat is similar to the one who use on your sunglasses when you try to clean them off, and it will naturally slow down your exhalation a bit and bring you closer to the 1:2 ration. As you practice this form of breathing, relax your throat as you inhale, engage your throat a little as you exhale. 

Baxter recommends doing a set number of repetitions of the 1:2 breathe, such as six rounds or twelve rounds. Then let your breath return to its natural length and depth, and notice how things feel internally. 

If controlling your breath in this manner is stressful, practice the exhalation pausing practice described above instead, and maybe give the 1:2 practice another try after you have some experience with breath work under your belt.

Because chronic stress can exacerbate or even cause anxiety (see Chronic Stress: An Introduction), I think it is also important that you address your overall stress levels in general (see The Relaxation Response and Yoga). So see if you can manage to incorporate some time for gentle or restorative yoga or any form of conscious relaxation into your schedule.

Friday A: The Three-Part Breath

Ladder by Melina Meza

Q: I was taught the way to breathe is through the belly to the chest and ending in the sternum area.  I saw a video from Leslie Kaminoff where he stated he does it the opposite way meaning sternum to belly. So, what does yoga teach us? Does it matter?

A: I’ll start right off with the assertion that from my perspective there is no one right way of breathing. And from my exposure to different styles of yoga and different modern lineages of yoga, I have often encountered conflicting recommendations on how to imagine the breath is moving in the body or how it is filling the lungs. But, as our reader points out, one of the more commonly taught ways of imagining, experiencing or encouraging the breath to come in on the inhalation is often called the three-part breath. In this variation, you imagine that you are filling your belly area with breath first (reflected in the belly gently expanding before any other part of the body or chest changes shape), followed by your lower chest, and lastly your upper chest. As an example, if you decided to do this over the course of a three-second inhalation, you could divide the filling or shape change of each area of your belly and chest into one-second increments. Remember you are not actually breathing into your belly, as your breath only goes into your lungs, which are located inside your ribcage! We suggest to our students that the breath is going into the belly during a full, relaxed breath because of the change in shape that takes place in that area of the body, when the breathing muscle—the respiratory diaphragm that separates the chest and abdomen—contracts and pushes down on the abdominal contents, leading to the outward bulge of the belly.

The exhalation is then sometimes said to exit in the opposite direction, from your upper chest first, your lower chest next, and your belly last. When performed in a relaxed, deep way, this breath is said to shift your nervous system to the Relaxation Response (Rest and Digest), slow your heart rate and lower your blood pressure, to name three typical benefits. But everyone experiences the breath differently, so not everyone will have those results, especially when first learning to breath differently. When I travelled to India in 2005, I was taught the style of breathing that our reader describes in his question, just the opposite of the more common three-part breath I just described. It is the same one Leslie Kaminoff describes in video that our reader mentioned. In this version of the three-part breath, you first invite your inhale into your upper chest, then your lower chest, and finally your belly. You then move your exhalation out of your belly first—with the assistance of the abdominal muscles contracting—then your lower chest and finally your upper chest. 

When I was first guided into this breath, I immediately recognized that it was the opposite of what I had been taught back home. But I was curious to try it and see what it felt like. My instructors at the Krishnamacharya Yoga Mandiram claimed this breath reflected the spinal movements that more naturally occur with inhaling (slight backbend of the spine) and exhaling (slight forward rounding of the spine), and stated that it would lead to a deeper, longer, fuller lung capacity. I have worked with both styles of breath over the ensuing years, and I can say for certain that one is not necessarily “better” than the other. 

Sometimes teachers of one method or the other will claim that the breath style reflects the movement of prana or internal energy in the body. Some sources state that prana moves upwards towards the head on inhalation, and moves downward on the exhalation, so therefore the first style of three-part breath reflects and supports that. Other teachers have suggested that there are energetic benefits to drawing the prana downward on the inhalation and releasing it upwards on the exhalation; and that inhaling downward towards the belly flips the digestive flame downward toward the lowest part of the belly, where the ancient Hatha yogis felt we stored all kinds of waste and toxins we needed to burn up. 

As I shared this potential difference of opinion with my friend and very experienced yoga teacher Susi Amendola, she promptly suggested the following:

“There is no one right way to breathe. There is just the ability to observe our habits and adapt if you discover that you are limited in your breathing capacity. Why are you reluctant to do a particular method of breathing: does it hurt, is it just weird and unfamiliar, or are you wed to a particular technique because you feel it is the “right way” to breath? These first two aspects are more interesting ways of assessing your breath than deciding which is the right way to do it.” 

I was reminded of the response of some of my fellow students back in India after we were first introduced to the second version of the three-part breath. Several said they would refuse to try the second version again because it was not the way they learned in their tradition, and it was therefore not something they were interested in learning.

So, when you are learning new pranayama techniques, consider giving it a try and notice how it makes your feel and how that jives with the purported benefits of the technique. If you are really struggling with either form of three-part breath, ask your teacher for guidance. Lastly, pick your teacher’s brain to see what other tidbits of wisdom about the breath you can learn.  Also, keep in mind that there can be an accumulated benefit of doing the breathing techniques regularly for a while, just as there is when doing your yoga asana home practice each day.  So add in a regular pranayama practice to your home yoga practice if you have not done so already!

Balancing Your Nervous System with Alternate Nostril Breathing

by Timothy

Mountain, Sky, Clouds by Melina Meza

In my last post Pranayama for Everyone: Bhramari Breath I wrote about the importance of pranayama (yogic breathing practices) and introduced one of my favorites, Bhramari, the buzzing bee breath. Today, I'm going to tackle the pranayama I consider the most important: alternate nostril breathing (Nadi Shodhana or Anuloma Viloma).

It turns out that almost all of us breathe primarily through one nostril for parts of the day, and then switch to breathing primarily through the other nostril at other times. The ancient yogis knew wrote about this and modern science has confirmed it (see p. 62 of my book Yoga as Medicine for details). Research has confirmed that breathing through the right nostril is linked to the sympathetic nervous system (SNS), whereas left nostril breathing activates the parasympathetic nervous system. This is pretty much exactly what's described in ancient yogic texts, albeit using metaphoric language. The left channel ida [pronounced ee DAH] is the feminine, lunar, cooling side, the texts say, whereas the right channel pingala [pronounced peen gah LAH] is the masculine, solar, heating side.

Many people in the modern world have an imbalance in their nervous systems, usually too much activation of the SNS, the flight or fight response. Others, such as some people with chronic fatigue syndrome, have too much parasympathetic tone. In either case, alternate nostril breathing can be useful. In Ayurveda, Nadi Shodhana is felt to be good for people of all constitutional types. I have found it particularly useful for students with an increase in the vata dosha (see Autumn, Healthy Aging and the Ayurvedic Dosha Vata), which is especially common now as we move into the cooler weather of the fall season.

If you have never tried alternate nostril breathing, you may have seen pictures of yogis using their fingers to alternately close of one nostril, then the other. Typically the thumb of the right hand is used to close off the right nostril and the fourth finger (or sometimes the fourth and fifth together) is used to block the left nostril. This "digital pranayama" is a wonderful practice that I've done daily for many years. But not everyone can do it.

For example, some people with arthritis find it too cumbersome or painful to use the fingers this way. If you've got a deviated septum or nasal congestion, digital alternate nostril breathing similarly may not work well due to the obstruction to air flow. In these instances, mental alternate nostril breathing, where you simply imagine to air going into one side and out the other is a great option. And the practice is so simple and safe that I often teach it to beginners.

To practice mental alternate nostril breathing, sit as you would for meditation, relaxed but perched high enough that your lower back can have its healthy inward curve. With your eyes closed, slowly breath in and out a couple of times. Then imagine you are inhaling through the left nostril and that you are exhaling through the right nostril. Next imagine inhaling through the right nostril, and exhaling through the left. Continue this pattern:

1. Inhale left
2. Exhale right
3. Inhale right
4. Exhale left

If you're new to pranayama, try this practice for just a minute or so. If it feels comfortable, you can continue for five minutes or longer. Since you began by inhaling on the left, end your session after an exhalation out the left nostril. Did you notice that your breath followed your intention?

If you are comfortable, I'd suggest you sit quietly for a few minutes after you finish or, if time allows, do a meditation practice. The ancient yogis taught that the balancing effects of Nadi Shodhana make it the perfect prelude to meditation, helping your meditation be calmer and more focused.

If you are an asana practitioner who tends to skip both pranayama and meditation, I have a challenge for you. For the next two weeks, try to do two minutes of mental Nadi Shodhana, followed by three minutes of sitting every morning before eating (or another time that suits you), and let us know how it goes. I suspect you'll be pleasantly surprised by the results.

Pranayama for Everyone: Bhramari Breath Practice

by Timothy

Bee and Flower by Melina Meza

One of the dirty secrets of the yoga world is how few yoga practitioners—and how few teachers—do pranayama, yogic breathing exercises. It's better in some yoga traditions than others, but overall I've been shocked to see how few of my colleagues practice pranayama regularly. This is a shame!

The breath is probably the single best way to affect the autonomic nervous system, which in turn controls the function of every internal organ, as well as systems like digestion and immunity. Pranayama can also be the gateway into meditation and higher yogic practices. Furthermore, there is a potential synergy: the regular practice of pranayama can make your asana practice subtler and more refined, and your meditation deeper and more concentrated. For therapeutic purposes, I believe there is synergistic benefit from doing some asana, along with pranayama, meditation, and other yogic practices.

Some schools teach that only experienced practitioners should attempt yogic breathing practices. There is wisdom in being careful, as pranayama done incorrectly—and especially if it's done too aggressively—can lead to problems with the nervous system and, in extreme cases, to psychological decompensation. But there are a few basic pranayama practices that I have found are safe for virtually everyone, and I'll be writing about them in this and my next few blog posts.

I'll begin today with one of my favorites: Bhramari [pronounced brah mah REE], which means the "buzzing of the bees." Although, in my experience, this is one of the pranayama techniques that's rarely taught (at least in many traditions), it's simple, safe, and has tremendous therapeutic potential.

To do a simple version of Bhramari, sit in a comfortable upright position as you would for meditation. Keeping your mouth closed, with your exhalation make a low- to medium-pitched humming sound in your throat. As you make the sound, which should last the entire length of the exhalation, tune into the literal vibration of the sound waves in your throat and even in your skull and brain. Then inhale through your nose, and if you're comfortable, repeat. Try to make your transitions into and out of each humming exhalation as smooth as possible.

At first, you might try Bhramari for a minute, but if it's goes well you can progress to a few minutes at a time. Depending on your breath capacity, the exhalation might vary from short to quite long. I'd suggest doing as long an exhalation as feels completely comfortable. At all times, each subsequent inhalation should be smooth, without any breath hunger. If you are feeling at all short of breath, you've likely pushed harder than you should, and if so, simply take a catch up breath and then resume Bhramari. If you feel at all agitated, I'd suggest you suspend the practice for the day and try it again another time with shorter exhalations.

Most people who do Bhramari as I've described it above will find the practice soothing. Since you will be lengthening your exhalation relative to your inhalation, the Bharmari breath activates the parasympathetic nervous system, and within a few breaths can bring you to a greater sense of relaxation and calmness. According to the classic text Hatha Yoga Pradipika, "with regular practice of bhramari, bliss arises in the heart."

A recent study Immediate effect of a slow pace breathing exercise Bhramari pranayama on blood pressure and heart rate suggested that the practice can lower blood pressure. In my yoga therapy work, I've found it useful for stress and various stress-related conditions, including insomnia (try a low-pitched sound). It's also useful for nasal congestion due to colds, allergies or sinus infections (use a slightly higher-pitched sound so that you can feel your nose and sinuses vibrating).

I even sometimes recommend Bhramari as a meditation alternative for people who find their minds so distressingly busy when they sit that they can't do the practice. It's harder for the monkey mind to go wild over the racket the buzzing of the bees makes internally, allowing you to settle in something moving in the direction of meditation.

Next up: Alternative Nostril Breathing.
