Yoga Relaxation Techniques: They're Not Interchangeable

by Nina

Patterns in the Sand 2, by Brad Gibson

Okay, I admit it. It’s probably my fault. I’ve been going around saying that you can trigger the Relaxation Response (see The Relaxation Response and Yoga) using any of the following: restorative yoga, inverted poses, Savasana, pranayama, meditation, and yoga nidra, etc. as if all those practices were somehow interchangeable. This has led to questions like the following comment left on a Friday Q&A: Yoga Nidra, Restorative Yoga, Meditation and Savasana:

It is very helpful to read the distinctions between these four practices as I try to practice all of them, but it's hard to find the time. I'd be really interested to get your thoughts on whether it's important to do all four? For example, if you do restorative while listening to a nidra CD, do you also need to meditate? I'm interested to know what the various benefits are of these four practices, or are the benefits all the same?

Let me start by saying that what I said previously—that you can use any of these practices for stress management—still holds true. And it is also true that you can choose whichever techniques you prefer to trigger the Relaxation Response. However, these practices each have different roles to play in a balanced yoga practice.

The role of meditation in a balanced yoga practice is particularly important. That’s why I asked Timothy to write an article on the purpose of meditation (see his absolutely wonderful post Is Meditation an Essential Par of Practicing Yoga?). Basically, although you can use meditation for stress reduction, its role in classical yoga is to quiet the mind to allow union with the divine or “liberation”:

1.2 Yoga is the cessation of movements of consciousness.
1.3 Then the seer dwells in his own true splendor.

— from Yoga Sutras, trans. B.K.S. Iyengar

Meditation is also, as Timothy mentions, a “fabulous tool to study your mind and slowly gain more control over it.”

Pranayama is also an important component of classical yoga, which precedes meditation as one of eight steps on the path to samadhi (union with the divine). It is considered an instrument to “steady the mind” and a gateway to dharana (the first phase of meditation).

“Pranayama removes the veil covering the light of knowledge and heralds the dawn of wisdom.

Its practice destroys illusion, consisting of ignorance, desire and delusion which obscure the intelligence; and allows the inner light of wisdom to shine. As the breeze disperses the clouds that cover the sun, pranayama wafts away the clouds that hide the light of intelligence.” — Sutra 2.52 trans. by B.K.S. Iyengar

On the other hand, the two types of asana I recommended for triggering the Relaxation Response, restorative yoga and supported inversions, are brilliant 20th century inventions, mostly developed by B.K.S. Iyengar, which are designed specifically to maximize physical relaxation and reduce stress. Judith Lasater, one of the most renowned teachers of restorative yoga, writes in the introduction to her book Relax and Renew:

“The antidote to stress is relaxation. To relax is to rest deeply. This rest is different from sleep. Deep states of sleep include periods of dreaming which increase muscular tension, as well as other physiological signs of tension. Relaxation is a state in which there is no movement, no effort, and the brain is quiet.

"Common to all stress reduction techniques is putting the body in a comfortable position with gentle attention directed toward the breath.”

Likewise, yoga nidra is also a 20th century invention (though you may see some claims to the contrary) developed by Swami Satyananda Saraswati. The first sentence of his book Yoga Nidra defines the practice like this:

“Yoga nidra, which is derived from the tantras, is a powerful technique in which you learn to relax consciously.”

In yoga nidra, you lie in Savasana while the voice of a teacher (or a recording) guides you through a physical and mental relaxation process. So, like restorative yoga, yoga nidra is specifically intended as a relaxation technique, and as such does not replace meditation or pranayama in a balanced yoga practice. This would be true of any form of Savasana in which an external voice is providing instructions and/or imagery for you. Unlike other relaxation techniques, yoga nidra includes a sankalpa (an intention) that allows you to influence your subconscious (or so it is claimed). For example, “I will awaken my spiritual potential,” “I will be a positive force for the evolution of others,” or “I will be successful in all that I undertake.” So this may be something you wish to take into consideration when choosing your relaxation practice.

Unlike the modern restorative postures, Savasana is a much older pose. Based on what I’ve read about the original practice, I’m going to go out on a limb here and say that Savasana is a reclining form of meditation. For some traditional yogis, it was a meditation on death, hence the literal translation of the name Savasana is “Corpse pose,” and it was sometimes even practiced alongside actual corpses. To practice Savasana properly, however, you must actually do the work of meditating while you are in the pose (and make sure you don’t fall asleep). If you don’t actually meditate while in Savasana, then, well, you are simply relaxing. But that's okay, too, if that is what you are after.

So there you have it. Which of these practices you decide to adopt really depends on what your goals are as well as your preferences. If you’re just after stress management and better health, it doesn’t really matter which you chose. However, if your goal is the “liberation” that is yoga’s ultimate aim, both pranayama and meditation are essential steps along the path.

Sorry if I caused any confusion!

Ultimate liberation is when the gunas, devoid of any purpose for the purusa, return to their original [latent] state; in other words, when the power of consciousness is situation in its own essential nature. —Yoga Sutra 4.34 trans. Edwin Bryant

Healthy Eating, Stress and Self Control

by Nina

One of the most important things you can do to support healthy eating is to practice stress management. Thought the reasons for this weren’t immediately obvious to me, the more I’ve looked into this topic, the more compelling those reasons become. Recently I wrote a post Yoga, Stress and Weight Management about how chronic stress causes weight gain by stimulating your appetite. As if increased hunger isn’t bad enough, it turns out that being stressed out can pose an even bigger challenge to your commitment to eating right: it weakens your willpower and causes you to be more impulsive. Say you had a long, traffic-jammed commute on the way to the office, there’s a critical meeting with a client that you make with a minute to spare, and someone’s left a big, pink box of fresh donuts glistening there on the table. Then, even though you planned a day of healthy eating, with a homemade lunch and a healthy snack, before you have time to stop yourself, you somehow you find yourself with a half-eaten donut in your hand.... Does this sound familiar to anyone? According to The Willpower Instinct by Dr. Kelly McGonigal, you’re more likely to cave in to temptation when you’re experiencing the stress response than you are when you are in a state of relaxation.

“While your body was getting ready to defend your life, the alarm system in your brain was busy trying to make sure you didn’t get in the body’s way. It focused your attention on the saber-toothed tiger and your surroundings, making sure no stray thoughts distracted you from the threat at hand. That’s right, the fight-or-flight response wants to make you more impulsive.”

As is often the case, a response that makes sense when your life is actually in danger (a time when over-thinking is probably not a good idea) can backfire on you in modern times. The traffic jams and the meeting with the client that were stressing you out weren’t exactly life threatening, so not being “distracted” by your plans for healthy eating won’t improve the situation (and might even make you feel worse after you come down from your sugar high).

Line of Moss by Brad Gibson

Fortunately, yoga has a few solutions to offer, both for the short term and the long term, to help you reduce the impulsive behavior that can accompany chronic stress. For the short term, Dr. McGonigal recommends slowing down your breathing to four to six breaths per minute, which she says helps shift your body from a state of stress to “self-control mode.” This is obviously something you could do discretely at your desk or even in that conference room where the donuts lay glistening at you. (Your meeting might even go better if you stopped for a minute to “center” yourself this way before it begins.) And since lengthening your exhalation is also a good way to turn down the stress response, I’d add that you could practice any form of pranayama that emphasizes the exhalation over the inhalation.

For the longer term, Dr. McGonigal recommends that you spend some time practicing conscious relaxation to “restore your willpower reserve.” She suggests lying down and breathing deeply, which sounds like Savasana (Relaxation pose) to me! Besides this, of course, yoga has a huge repertoire of ways you can de-stress, including meditation, yoga nidra, restorative yoga, supported inverted poses, and active asana poses practiced with mindfulness (see The Relaxation Response and Yoga for further information).

So if you’re having trouble sticking to your healthy eating plans for the new year, why not experiment by trying one or more of these relaxation techniques and see if they strengthen your willpower. I’d love to hear back about any results. (Besides, if worse comes to worst, you’ll at least be less stressed out!)

Featured Pose: Easy Inverted Pose

by Nina (with a little help from Baxter)

Supported inverted poses are some of the most wonderful yoga poses for reducing stress. By physically inverting yourself (having your heart higher than your head), you employ the natural physiology of your body (the mechanisms that control your blood pressure—see Blood Pressure: Talking About Baroreceptors and Yoga) to invoke the relaxation response. However, in order for an inverted pose to work its magic, you not only need to be able to do it, but it also must be comfortable for you. If you’re in pain or even just uncomfortable you’ll be slightly stressed, so the relaxation response won’t be triggered and you won’t be able to relax completely.

So what’s a person with a bad lower back (a problem for Supported Bridge pose and standing forward bends with head support), tight hamstrings (a problem for Legs Up the Wall pose), or tight shoulders or neck issues (problems for Supported Shoulderstand, Half Plow pose, and Supported Downward-Facing Dog pose) supposed to do? And what about people who are afraid of being upside down or have been recommended to avoid it due high blood pressure or heart disease?

The answer, my friends, is today’s pose, which Baxter and I like to call Easy Inverted pose. Resting your calves on a chair with a support under your pelvis puts your body into a slightly inverted position, so the blood flows from your legs down toward your heart (the opposite of standing upright). So Easy Inverted pose is a very calming inversion, which is also very restful for your leg muscles. (In fact, I find it so effective that I can feel myself start to relax just thinking about it!) And, yet, Easy Inverted pose is so comfortable and accessible, almost everyone can do it (hence the name). If the support under your pelvis irritates your lower back, you can simply do the same pose without it. And one of my favorite MDs (that would be Baxter, of course) assures me that this is a safe pose, too, even for people who have controlled high blood pressure, managed coronary artery disease, or glaucoma (see below for a few cautions).

You can practice this pose on its own for stress management or as an alternative to Savasana at the end of any longer practice. When I’m teaching supported inversions, this is my “back pocket” pose. When a student can’t get comfortable in any of the other poses, I pull this one out for him or her and so far have always found success! I hope you do, too.

Instructions: To set up for the pose, find a chair either with an opening through the back you can put your legs through or one your can turn sideways to let your feet dangle off of. Place a blanket or folded yoga mat on the chair on the chair seat to soften the surface. (If your legs are long, you may need to place extra padding on the chair seat.) Next, if you are not practicing on a carpet, you may wish to set a yoga mat on the floor in front of the chair (we don’t show that in the photo). Then stack one or two blankets folded length-wise about a foot or so from the chair legs (you’ll have to experiment for your body type to find the exact length). This will support your pelvis when you are in the pose. Finally have another blanket, towel or thin pillow nearby to put under your head.

To get into the pose, sit sideways on your pelvis support. Then, using your hands on the floor to stabilize yourself, swing your calves up onto the chair seat. Finally, with your legs resting on the chair seat, lie back and place your head under your head (but not under your neck or shoulders). Allow your arms to rest on the floor, slightly away from your body.

Make sure that your pelvis is close enough to the chair seat so your calves can actually rest comfortably on the chair seat (they should be completely relaxed). But be far enough away from the chair so your thighs are at a good angle (not perpendicular with the floor). Now close your eyes and allow your body to relax. (If you wish, you can put an eye pillow or silk scarf over your eyes as the final touch.)

To come out of the pose, bend your knees and move your feet to the edge of the chair seat. Then slowly, slowly, slowly roll over onto your right side for a couple of breaths. From there, slowly, slowly, slowly use your hands to push yourself up to a seated position, leaving your head for last.

Cautions:  Baxter says that although this is a generally safe pose, if you are on blood thinners or tend to have blood clots, don’t stay in the pose more than 5 to 10 minutes. For lower back problems, instead of using the lift under your pelvis, try turning the blanket the opposite away to support your torso, from your tailbone up through your head.

Friday Q&A: Propping for Relaxation Pose (Savasana)

Q: I have been wondering something about Savasana: Aside from the fact that Savasana has not been all that great for me due to low back/SI joint issues which are lately resolving, I find that my knees feel like they hyperextend in the relaxed state with gravity's pull. Would that alone be reason to always place a support under my knees, or not necessarily? Additional information: I developed the habit of sleeping with pillows under my knees probably 15 years ago at the recommendation of a physical therapist I was seeing at the time for neck problems. Lately my back & SI problems are greatly improved so now I am noticing the feeling of knee hyperextension more as I try to back off of over-reliance on knee support during Savasana. Engaging the quads to ease that seems counterproductive to Savasana. I feel fine with props. I just don't want to overuse them if that would set me up for some imbalance elsewhere.

Thank you so much for your time and dedication to the mission of educating us!

A: I have studied with the foremost expert (in my mind and others) on restorative yoga, Judith Lasater, and her teaching as I interpret is that a restorative pose should feel WONDERFUL when you are in it. The aim of Savasana is deep relaxation, and sometimes we have to work a little to get the pose perfect. So if you need to prop your knees or arms, support your head or low back, or whatever, then that is what you need to do for YOUR Savasana to be inviting and nourishing. There is no one way to do any yoga pose, and that is the gift of yoga which is to find out what works for you.

Please allow yourself to explore and experiment in how you position yourself for the utmost ease and enjoyment. Yoga is not “one size fits all.”

Happy journey.

Restorative Yoga: An Introduction

by Nina

Last fall I did a series of posts on yoga and stress. Working from my first major post on the topic (see Relaxation Response and Yoga), which listed the various types of poses and practices that are helpful for stress, I added posts that expanded on each of the items I listed, except one: restorative yoga. My reason for skipping over the topic of restorative yoga was simple: I didn’t have any good photographs of restorative yoga poses that I could use with my post! But last week for Baxter’s post on digestion (see Mini Restorative Practice for Digestion), I finally had a chance to take a few photos of three of the classic, most frequently practiced restorative poses. And I woke up this morning realizing that it was finally time to address this topic.

Restorative yoga is a form of yoga that was specially designed to provide deep rest and relaxation. In restorative yoga, you use props to support yourself in the shape of a classic yoga pose, including forward bends, backbends, side stretches, twists, and inversions. For example, in Child’s Pose, rather than folding forward all the way on to the floor, you use a bolster or stack of folded blankets to support your entire front body.

The props you use in restorative yoga not only make the pose more comfortable but they take the effort out of the pose. Rather than using your muscles to hold you in the shape of a pose as you would normally, the props hold you in the pose so you can simply let your muscles relax. With your muscles completely relaxed, you can then turn your attention inward, focusing on your breath, physical sensations, or any other object of meditation, which allows the relaxation response to switch on.

Restorative yoga is perfect for those days when you depleted, sick, stressed out, low on energy or are just in the mood for a soothing practice. For people who can’t practice inversions for stress reduction, restorative yoga poses are an excellent alternative. For example, Reclined Cobbler’s pose with props is the perfect choice for a 10 to 20 minute stress reduction practice.

Are you looking at this photograph and wondering why you would want to go through all the trouble of getting all those props together when you can just lie down in Savasana (Corpse pose)? Well, I’m writing today to answer that very question.

First of all, like active yoga poses, the type of restorative pose you do can have a strong effect on your moods and emotions. And because you typically stay in a restorative yoga pose for longer periods of time, the emotional effect can be even stronger. For example, the forward bend of Child’s pose is normally quieting (as a forward bends for people who can practice them comfortably), and the restorative version is even more quieting. Active backbends can be simulating and uplifting, and while the restorative versions are not stimulating (all the effort is taken out of them), a restorative backbend can also be uplifting, providing an anti-depressant effect. (See Yoga and Your Emotions for information on the emotional effects of poses.)

And, secondly, in Savasana your body is in an anatomically neutral position, so no muscles are being released or stretched. In a restorative pose, however, you still receive many of the benefits of the pose itself. For example, in a restorative backbend, you are opening your chest and stretching many of the muscles that become tight after driving long distances or sitting hunched forward at a desk all day. Passively stretching your muscles as your relax increases your feeling of relaxation, as some of the stress you have been holding in your body is gently released. And because you are completely comfortable and relaxed, you can stay in the pose for much longer amounts of time. So restorative poses are actually a good way to work on flexibility, as well as relaxation.

But the best way for you to understand the benefits of restorative yoga is to experience them. So if you’ve never tried restorative yoga, experiment by trying either one of the poses I’ve shown today (or any other you’ve seen before). As always, you can just do a single pose or you can do short or full-length sequence (see Mini Restorative Practice for a short sequence). If you’re feeling hyper from stress or anxiety, you may find it difficult to lie down in a restorative pose. In this case, I recommend doing either an active yoga practice or some other form of exercise first before the restorative pose.

New Releases: Yoga Nidra and Deep Physical Relaxation

by Baxter and Nina

Happy New Year, everyone! We've been talking for some time about providing you with a few relaxation tracks that you can stream from our site or download onto your own audio devices. Now, at last, thanks to help from Margy Cohea and Quinn Gibson, we're pleased to release our first two tracks, both featuring Baxter Bell.

We're starting out by providing two shorter relaxation sessions, around 15 minutes each, because we know so many of you have busy schedules or aren't quite ready to commit to a whole hour of yoga nidra. You can play these tracks directly from our blog, or, if you wish to download a track, you can go to our new—gotta love it—Band Camp site (see http://yogaforhealthyaging.bandcamp.com/). Band Camp earns money through the donations you make when you download a track, so if you can afford it, help us support this wonderful site.

The first track is a physical relaxation practice, intended to be practiced in Corpse pose (Savasana). Baxter will gradually guide you, step by step, into a deep relaxation of your entire body and nervous system.
The second track is Baxter's 15 minute version of a yoga nidra practice, which is also intended to be practiced in Corpse pose (Savasana). Baxter will guide you into the state of conscious relaxation that is also referred to as "yogic sleep."
Let us know what you think! And if you have ideas for other audio tracks you'd like us to provide, be sure to let us know.

Just in Time for the Holidays: Inverted Poses

by Nina

In my original post about the relaxation response and yoga (see here), I mentioned that inverted yoga poses are one of the many ways you can trigger the relaxation response. Inverted poses are my personal go-to stress busters of choice, and if I could get my hands on Paul Weston (see here), I’d certainly teach him one or more of these amazing poses. So today I’m going to explain what I mean by “inverted poses,” and I’ll also provide some scientific background on them because understanding why these poses work can help you get the most out of them. Okay, here goes:

Any yoga pose where your heart is above your head is considered to be an inversion. Inverted yoga poses include full inversions, such as Headstand and Shoulderstand, where your heart is directly over your head and the rest of your body is also fully inverted. Also included as inverted poses are partial inversions, such as Downward-Facing Dog pose and Standing Forward Bend, where your heart is less directly over your head and your legs are either not fully and not at all inverted.

Standing Forward Bend from Yoga: The Poetry of the Body

The reason these poses trigger the relaxation response turns to be related to the mechanisms that control your heart rate and blood pressure. The nerves that control your heart rate and blood pressure are regulated through pressure sensors called baroreceptors. Your baroreceptors are located in the wall of each internal carotid artery at your carotid sinus (the arteries on each side of your neck that carry blood from your heart to your brain) and in the wall of your aortic arch (just above your heart). These baroreceptors detect any changes in your blood pressure, stretching when blood pressure is high and shrinking when blood pressure is low.

If your baroreceptors detect a fall in your blood pressure, they send signals via your nerves to increase your heart rate, constrict your blood vessels to raise your blood pressure, and switch your nervous system to fight or flight mode. Likewise, if your baroreceptors detect abnormally elevated blood pressure, they send signals to slow your heart rate, relax your blood vessels to lower your blood pressure, and switch your nervous system to relaxation mode.

In an inverted pose, your heart is higher than your head, the opposite of its position when you are upright. With your heart higher than your head, gravity causes more blood to flow in the direction of your head, creating more pressure than usual on your carotid sinus and aortic arch. As the arterial pressure is increased, your baroreceptors are stretched and signals are transmitted to your central nervous system as if your blood pressure was high throughout your body. Feedback signals are then sent back to your body to reduce the arterial pressure, slowing your heart rate, relaxing your blood vessels, and releasing hormones that decrease adrenaline production. This automatically switches your body to relaxation mode.

In addition, inverted or partially inverted poses where your neck is flexed (that is, your chin is pointing toward your chest), as in Shoulderstand, Plow pose, or Bridge pose, puts additional pressure on your carotid sinus (the arteries on each side of your neck that carry blood from your heart to your brain). This added stimulation of your baroreceptors may enhance the calming effects of the inversion.

How simple is that? As long as you are warm, quiet, and comfortable in the inverted pose, all you have to do is let pose work its magic! Naturally, supported versions of the poses (such as Shoulderstand with a chair or Bridge pose on blankets) are more relaxing than straight versions of poses in which you must support yourself, so if you’re practicing inversions for stress reduction, choose the supported versions.

In the coming weeks, I’ll provide details about the various inverted poses, but until then, the following is classic sequence of calming inversions. You can do any or all of these poses, but if you do more than one, I recommend doing them in the order shown below.

1.    Downward-Facing Dog pose, with your head resting on a block or folded blankets (1 to 3 minutes)
2.    Standing Forward Bend, with your head resting on a block or with folded arms and head resting on a chair seat (1 to 3 minutes)
3.    Wide-Legged Standing Forward Bend (Prasarita Padottansansa), with your head resting on the ground, a block, or the seat of a chair (1 to 3 minutes)
4.    Headstand (3 to 10 minutes)
5.    Shoulderstand, with a chair (3 to 10 minutes)
6.    Half Plow pose, with your legs supported by a chair seat (1 to 3 minutes)
7.    Supported Bridge pose, with your shoulders and head resting on the floor, your torso and legs supported by blankets or bolsters (5 to 15 minutes or longer)
8.    Legs up the Wall pose (Viparita Karani) with your pelvis supported with a bolster or blankets (5 to 15 minutes)

I’ve taught this sequence many times, and there are always people in each class who have difficulty with one or more of these poses. So I always teach a non-classic pose as well, Easy Inverted Pose (see here), because this is one pose almost everyone can do. Use this as a substitute for Shoulderstand, Plow pose, Bridge pose, or Legs Up the Wall pose, or just use it on its own.

Caution: Inverted poses may be unsafe for those with certain medical conditions (see here).

Yoga for Insomnia, Part 1

by Nina

Paul Weston and his new therapist from "In Treatment"

There I was on Saturday night, doing that thing where you talk out loud to a fictional character on your TV screen. But, really, Paul Weston in Season 3 of “In Treatment” was asking his new therapist for another Ambien prescription. And when he told her that he’d been taking Ambien every night for over a year, I just lost it. I said, “That’s addiction, not a solution! You need to help him wean himself off the pills!” But his therapist wouldn’t listen to me. And then Paul told her that even with the pills he didn’t sleep through the night, but always woke from a nightmare after several hours, and then had trouble going back to sleep, often taking another Ambien to get himself through the second part of the night. He was worried that he might have Parkinson’s Disease. But even though I begged her to offer him an alternative, in the end his therapist wrote him another prescription and said he could come back and talk to her if he wished, so besides the pills all she had to offer him was long-term talk therapy.

Then on Sunday morning I was doing it again because I read an article in the NY Times “Sleep Medication: Mother’s New Little Helper” (see here) about mothers who can’t sleep because they are too stressed out about all the little things they had to do, and instead spend hours in the middle of the night fretting over their “To Do” lists. Both the author of the article and the women themselves seemed to think the only options these women had were sleeping pills or lack of sleep. “Conscious relaxation!” I shouted to the author and the women in the article, but to no avail. It is just part of being a mom these days, they claimed. Some of them even talked about how useful it was to have time to themselves in the middle of the night, when they could get even more work done.

It’s a good thing I can rant in this post today! I do think sleeping pills can be useful on a short-term basis to get you through a short, difficult spell, but they are not a long-term solution because they do not solve the underlying problems (and you do, in fact, become addicted after just two weeks). If you read my first post on chronic stress (see here) you will know that what’s keeping both Paul and the women in the NY Times article from sleeping well is chronic stress. And a different solution to their insomnia could be practicing yoga stress management techniques. So what would I prescribe for Paul Weston?

During the afternoon or evening, Paul should practice calming yoga poses, such as restorative poses, supported forward bends or supported inversions (such as Legs Up the Wall Pose). Seated meditation is another good option for this time of day. If Paul can do Savavana or yoga nidra without falling asleep, these practices would also be effective, but taking a nap won’t be effective. The idea is for him to switch his nervous system from chronic stress to the relaxation response, providing him with time in a state of conscious relaxation. (See here for info on the difference between conscious relaxation and sleep.)

Then when Paul is in bed trying to fall asleep, I’d recommend either yogic breath awareness (or extending the exhalation) or a self-guided Savasana (such as progressive physical relaxation of different body parts) so that when he falls asleep he will be more relaxed (and will hopefully sleep deeper and longer). Even though he has important things to worry about, the key is to keep his mind on neutral subjects when he is going to sleep (he can always do his worrying the next day!).

Finally, if Paul wakes in the middle of the night, rather than getting up and turning on the light to read a book, work on the computer, or watch TV (these activities are mildly stimulating), I’d recommend that Paul stay in bed in the dark, and again do a yogic breath practice or a self-guided Savasana. There is a good chance this will help him get back to sleep again. Granted, worrying is very tempting; in the middle of the night it feels like important work. But like any other practice, moving the mind away from worry to a more neutral subject gets easier and easier with experience.

“Paul,” I’d say, “I’ve been there, too. And these are all practices that have helped me learn to sleep better, even during stressful times.”

Friday Q&A: What is Yoga Nidra?

 

Q: What is yoga nidra (yogic sleep)?

A: Well, this is a good question. A straight up translation is “the sleep of the yogi,” however, done correctly, one does not enter fully into sleep, but is guided by a teacher on a journey while resting in a restorative version of Savasana. I love this practice, as it can lead to a profound conscious rest (that means, again, you are not sleeping!) that has many physiologic, mental and emotional benefits.  Because you are listening and following the voice of a teacher while resting anywhere from 20-45 minutes, your mind is gently occupied and does not tend to revert to its typical habits of remembering, anticipating or judging. This provides a mental respite for your mind, and your body tends to more quickly shift into the rest and digest part of the nervous system, even faster than in normal sleep. Yoga nidra is being used to treat PTSD in vets returning from Iraq and Afghanistan, so the potential effect on anxiety, fear and worry seems obvious.

You can practice yoga nidra is the physical presence of the teacher who is guiding you (in a class or workshop) or on your own using a recording of your favorite teacher. And I hope to record a version of yoga nidra for your listening pleasure in the next few weeks. Nina will fill you in on yoga nidra’s modern roots, which may surprise some of you who have been told it is an “ancient “practice.” — Baxter

A: Yoga nidra was developed by Swami Sivananda Saraswati in the early twentieth century (based on the teachings of his guru, Swami Sivananda). Yes, the twentieth century. He wrote, “I came across many important but little known practices, which interested me greatly. After practicing them myself, I decided to construct a new system called yoga nidra which would incorporate the essence of these practices without having complicated ritualistic drawbacks.” He says the yoga nidra practice was inspired by the tantric practice of nyasa, but nyasa was performed in a sitting posture and involved the use of specific mantras which were “placed” in different parts of the body.

Swami Sivananda Saraswati’s disciple Swami Satyananda Saraswati describes the yoga nidra practice in great detail in his book Yoga Nidra. Swami The form of practice taught by Swami Satyananda includes eight stages: Internalisation, Sankalpa, Rotation of Consciousness, Breath Awareness, Manifestation of Opposites, Creative Visualization, Sankalpa and Externalisation. Contemporary teachers, such as our very own Baxter Bell, often create their own versions of yoga nidra.

So yoga nidra is not ancient after all! But that doesn’t mean it’s not a very powerful practice. Much of the yoga that we know and love was actually developed by a few brilliant Indian yogis during the early twentieth century (Desikachar, Iyengar, Jois, etc.), a very exciting and fruitful time in the long history of yoga.

In simple English, yoga nidra is a practice where you lie in some version of Savasana (Corpse pose) and allow a teacher, who is following a format devised by Swami Sivananda Saraswati, to guide you into a state of conscious relaxation that is referred to as “yogic sleep.” It doesn’t feel like being asleep and it doesn’t feel like being awake—trust me, I’ve tried it.

Conscious Relaxation vs. Sleep

by Nina

Did you ever wake up in the middle of the night with your heart racing, short of breath, mouth dry, and thoughts racing? Maybe you just had a nightmare. Or maybe your mind was spinning, worrying about some difficulty at home or at work, or even about a disaster somewhere else in the world. Then you know intuitively that sleep is not necessarily “relaxing.”
 

Dr. Herbert Bensen, who originally discovered the relaxation response (see here for information), tells us that sleep, although necessary for our physical and emotional wellbeing, is a very different state than conscious relaxation. He identified the following four basic differences:

1. Dreams can actually cause stress through nightmares and anxiety dreams. During conscious relaxation on the other hand, your production of stress hormones gradually decreases, and other symptoms of stress, including both the physical and emotional sensations, subside.

2. During conscious relaxation, oxygen consumption decreases 10 to 20 percent during the first 3 minutes of practice while during sleep it decreases only 8 percent after about 4 or 5 hours. This reduced need for oxygen reflects the fact that during conscious relaxation your body is in rest and digest mode, not in stress mode where you are preparing to run or fight.

3.    During conscious relaxation, there is a marked decrease in blood lactate, a substance associated with anxiety attacks. Blood-lactate levels fall rapidly within the first 10 minutes of conscious relaxation, while sleep has no effect on blood-lactate levels. As you relax, your thoughts stop racing and your mind quiets while your body is resting and digesting.

4.    Alpha waves (slow brain waves) increase in intensity and frequency during conscious relaxation, but are not commonly found during sleep. Dr. Roger Cole, a sleep researcher and long-time yoga teacher, says that during rest or meditation our brain waves may slow to the alpha rhythm (8-12 cycles per second), during which we remain quietly aware of ourselves and our surroundings, without a lot of self-directed mental processing. Sometimes they may slow even further to the theta rhythm (4-7 cycles per second), during which we may get a “floating” feeling, dreamlike mental imagery, and withdrawal from the outside world. There is still much that is unknown about these unique states, but what is known is that regular practice of conscious relaxation helps foster ongoing feelings of serenity, contentment, and even happiness.

Now you can see why taking a nap or sleeping in on Sunday morning just won’t produce the same results as yoga. On the other hand, practicing conscious relaxation on a regular basis will not only provide you with immediate relief, it can also reduce your overall stress levels, so you can maintain your health and face the difficulties that life presents with greater equanimity. To be honest, I don’t practice conscious relaxation just because I’m hoping that it will reduce my chances of getting heart disease or having a stroke in the future (although that’s definitely a bonus), I do it because it makes my life better, right here, right now.

Furthermore, as anti-intuitive as it might seem, relaxing while you are awake can even help you sleep better. When you are under great stress, it is difficult to fall asleep. Or, if you can fall asleep (because you are so tired) you often can’t stay asleep. To sleep well, your nervous system needs to be relaxed (if you are in a state of stress, you will be wakeful and alert, watching for danger) and your mind needs to be quiet (if your thoughts are racing, reviewing the past or worrying about the future, you will have a hard time settling down). But conscious relaxation, especially practiced before bed, will relax your nervous system and quiet your mind. And any of the methods I listed in my Monday post will produce these results. See here for further information.

THE RELAXATION RESPONSE AND YOGA

by Nina

Last week I wrote about the stress response, and how dangerous chronic stress is for your physical and emotional wellbeing (and possibly your longevity). So at this point you might be wondering: wouldn’t it be nice if there were an easy way for you to switch off your stress? I mean, something quicker and less expensive than a month in Tahiti or a week in a spa.

Well, it turns out there is. Remember, between stressful situations, your body needs to rest, recover, and acquire new energy. So your nervous system responds by:

• lowering your blood pressure
• reducing your heart rate, diverting blood back to the skin and gastrointestinal tract
• contracting your pupils and bronchioles
• stimulating your salivary gland secretion, accelerating digestion, and promoting normal movement of food through the gut

Dr. Herbert Benson coined the term “the relaxation response,” to describe this phenomenon, and he discusses it in detail in his book The Relaxation Response (which I highly recommend). I’ve also heard the term “rest and digest” to describe this state, when your body is recovering and restoring itself, and I find this is a helpful way to think about it, as the opposite of “fight or flight.”

Of course when you are stressed out, you can’t just tell yourself to relax. (I remember when I was suffering terribly from chronic stress, a therapist told me to “stop worrying.” I said, “Are you kidding?” and, duh, never went back.) But this is where yoga performs so brilliantly. Because, as Dr. Benson discovered, to trigger the relaxation response all that is required is:

1. A quiet environment

2. A focus for your mind, such as a sound, word, phrase, physical sensation (breath or body part), or fixed gaze at an object

3. Passive (non-judgmental) attitude

4. A comfortable position

5. 10 to 20 minutes

If this makes you immediately think of meditation, you’re right about that. But yoga has bunch of different options that you can use to trigger the relaxation response:

1. Meditation. See here for information on how to meditate.
2. Breath practices (pranayama). See here for information your nervous system and your breath.
3. Restorative poses with a focus for the mind (such as your breath or the relaxation of your muscles).
4. Corpse pose (Savasana) with a focus for the mind (such as your breath, the relaxation of your muscles, or peaceful imagery). See here for information.
5. Yoga nidra (yogic sleep), a long, structured form of Savasana. See here for information about yoga nidra and here for a mini version of yoga nidra that you can stream or download.

Eventually, after his initial studies, Dr. Benson removed two items from the list: a comfortable position and a quiet environment. He soon realized that a mind-body practice, such as the yoga asana practice, can be a “moving meditation,” as long as there is a focus for your mind (such as the physical sensations of your body in the pose) and a passive attitude (refraining from judging yourself in the pose, such as how you look or whether you’re doing it “right”). See "What is Mindfulness?"

Finally, studies by Dr. Roger Cole proved that inverted and semi-inverted poses, where your heart is higher than your head, trigger the relaxation response through the mechanisms that control your blood pressure. This is why supported inversions, such Legs Up the Wall pose and Easy Inverted Pose (legs on a chair), are so effective. I’ll write soon specifically on inversions and how they work (see "Just in Time for the Holidays: Inverted Poses").

And in weeks to come, we’ll provide further information about all seven of these options for triggering the relaxation response: meditation, breath practice, restorative yoga, Savasana, Yoga Nidra, mindful yoga practices, and inverted poses.

By now you may be saying to yourself that while these practices definitely seem like a bargain compared to vacations and spas (free to be exact), they seem like a bit of work. Can’t I just skip all this “practicing” stuff and get a bit of shuteye instead? Sorry, but it turns out the state of conscious relaxation you achieve by triggering the relaxation response is very different than sleep, and I’ll be discussing that difference in my next post (though, of course, a good night’s sleep is also important for your physical and emotional health). See here for a comparison between conscious relaxation and sleep.

What about turning on the TV or reading a good book? Activities, such as TV and reading, while good distractions, aren’t necessarily relaxing. Hey, suspense, though good for a plot, can be very stressful, and I not only cry at the movies, but sometimes during sad parts of a novel! I’m not saying you should never watch TV or read, just that these activities can’t take the place of the conscious relaxation that yoga provides. So as Baxter said last week, "Got 10 minutes?"

And now, dear readers, I’d like to ask you for your help. What are your favorite yoga stress management techniques? What do you find the most useful? And have I overlooked anything? Also, if you’d like to vote on which yoga stress management techniques you’d like to hear about first, let me know.
