Explore the Anatomy and Correct Alignment of Headstand Pose
Knowledge dissolves fear. With a basic understanding of the structures in your neck, and application of these five keys, one can practice sirsasana safely.
Let’s first take a look at the anatomy, and the neck’s role in our daily life.
The seven little bones of the cervical spine (neck bones) are unique in that they are designed for mobility rather than stability. Like other joints in the body, where stability is sacrificed for mobility, the primary purpose of the C spine in daily life is ease of movement. Therefore, ideal alignment and muscular harmony are particularly important.
The load bearing structures of a cervical vertebrae are the body and two articular facets. A typical cervical vertebral body is approximately two centimeters in diameter depending on the vertebrae (C3 – C7), gender, and individual differences. This is comparable to the diameter of a dime. One may make the comparison of a lumbar vertebral body and cervical vertebral body to the chunky heel of a walking shoe to a high heeled pump. Imagine walking a gravel road in stilettos versus the former.
Another feature worth noting is that the C spine houses the vertebral arteries. Transverse foramen, or holes from top to bottom on the side wings of the bones, house this paired blood vessel which travels up to the brain, taking a rather alarming posterior jog at the top of the neck bones before entering the skull. Symptoms of blocking this small artery include dizziness, blurred vision and occipital headaches. Any lesion compromising the integrity of this passage way is exacerbated by misalignment and the additional and uncustomary weight of your body on the cervical vertebrae in a posture like sirsasana.
Nerves exit the intervertebral foramen (holes in the sides between the neck bones), the branches of which pass laterally between the anterior and middle scalene muscles. These muscles help to hold your head and neck up like guide wires, and provide movement in your neck. Overuse these muscles through misalignment or overload them, and they will become inflamed or tight, possibly pinching the nerves.
How to Safely Practice Headstand (Sirsasana)
Armed with this information, how can you incorporate sirsasana safely into your practice? Headstand or any posture for that matter doesn’t have to look like the pose in your yoga syllabus to start. Practice the actions of the pose in a modification, and you will receive more benefit than forcing the pose.
Here are some important points to practice sirsasana.
1. A strong headstand begins with sensible upright posture.
Carry your upper palate above your physical heart. Assume a natural lordosis in your neck. Your best posture will be your tallest, most easeful posture. Maintain this easeful alignment of your spine in upright yoga postures. If you don’t know what good alignment feels like upright, you won’t know what it feels like upside down.
Practice holding Tadasana in ideal alignment and full attention for several minutes. To simulate the postural muscles further, root down from the outer hips into your feet. Place a block on top of your head while standing, and root up into it from your upper palate as you gently resist. Breathe fully to expand and lengthen your torso. Drop your shoulders away from your ears, and slide the upper arms back to widen the clavicles (collar bones). Invite the ribs back, as this action tends to cause them to splay forward. Breathe into your back, particularly just above the waist.
Practice integrating your body from head to feet with these polar actions of rooting and lifting. When you are in perfect alignment, your body will feel like your favorite pair of walking shoes: No friction, no effort, just ease.
Which brings me to the next key.
2. Stretch your hamstrings and plantar fascia.
To get into any posture, the closer to ideal postural alignment you can get, the less likelihood of injury. To keep your neck safe in headstand, you need to be able to align your entire spine before taking away the support of your feet. In order to achieve this, the back of your legs and soles of your feet must be supple enough to walk into the posture without rounding the lower back and therefore the neck.
3. Apply the rules of progressive overload.
No one walks into a gym and does a clean and jerk with 150 pounds off the bat with no experience. So why would headstand be any different? The neck is accustomed to bearing a mere ten pounds of weight. Add resistance incrementally in weight and duration.
4. Create a stable foundation.
** **When you are ready to do sirsasana, interlace your fingers into prayer hands, with the exception of your pinky fingers. Your pinky fingers should be stacked, overlapping each other front to back. You should be able to see both middle fingers from above but not any of your palm to start–so slightly pronate your forearms. Once you tuck your head into your palms, the tendency is to roll onto the dorsum (back) of your hand. Starting in slight pronation will bring you into neutral alignment once you are in the posture. Now root down through parallel upper arms into the forearms, wrists and hands while keeping the spine neutral and your chest open. Nestle the back of your head into your hands. Distribute the weight between the crown of your head, forearms, wrists and hands.
5. Keep your mouth shut.
This one is mostly for teachers. Although designed primarily to aid in tongue movement and swallowing, the variety of muscles attached to the base of the tongue help to support your neck. Anchor the tongue to the roof of your mouth for additional stability. When it comes to standing on your head, recruit as much help as possible. So teachers, explain your demo first, and don’t speak once you are in the posture.
Precautions and Contraindications
There are precautions and contraindications to performing sirsasana, such as osteoarthritis of the C spine, any autoimmune disease affecting the musculoskeletal system, diabetes, heart condition, degenerated discs, down syndrome, or any other pathology affecting the neck.
However, even with these conditions, one can enjoy many of the benefits of the pose by simply embodying the actions of the pose in a modified form. With patience and keen attention, headstand can be performed safely to benefit your wellbeing.

What Really Happens in Hip Openers
One of the most common requests heard in a yoga class is hip openers today please. This request is usually followed by the other half of the class groaning. We love to hate hip openers yet our bodies crave them and often feel lighter and more open after — for good reason. The majority of us sit for most of our days, shortening the hip flexors at the front of the hip (psoas, rectus femoris, sartorius) and tightening the hip rotators (piriformis, obturator internus, gamellus, to name a few).
A Look Inside the Hip
The hip joint itself is a ball and socket type joint with the head of the femur (thigh bone) sitting in the acetabulum or socket of the pelvis. A variety of muscles attach into the femur starting from the pelvis itself, the lumbar spine, the sacrum, or other parts of the femur. Hip openers could affect any of the muscles surrounding the hip depending on the position of the joint at the time of the pose.
In general when we stretch or open a muscle we are lengthening its position, moving the two attachment points away from each other. This is easy to assess with linear muscles like the psoas which attaches from the front of the lumbar spine, crosses through the pelvis and attaches to the head of the femur. If we flex the hip forward we are shortening the psoas, bringing the two attachments of the muscle closer together. If we extend the hip backwards (such as in the back leg of Pigeon pose we are opening and lengthening the psoas. The effect becomes greater in King Pigeon pose if we assume an upright posture with our spine so that we lengthen the upper attachment more. In this example we can also rethink our definition of hip openers. Suddenly, poses with a bent knee where we rotate the hip are not the only way to open our hips. If the psoas attaches into the femur, and a shortened psoas tightens our hip (not to mention the affect it has on our low back) then poses like Warrior / Virabhadrasana or Half Moon / Ardha Chandrasana become hip openers too.
Rotate to Open a Rotator
The rule of how to open a muscle becomes less clear with the hip rotators where the angle of the joint actually affects the action of the muscle. For example, the piriformis muscle attaches from the front of the sacrum to the back of the femur. It acts as an external or outward rotator of the hip. Except if the hip is flexed, then it assists in abduction or sideways movement of the hip. So to follow the rule of opening we would want to internally rotate the femur, flex the hip and adduct or bring the femur towards midline. This can be achieved with the top leg in Marichyasana (sit with your left leg extended, bend your right knee and step the foot across your left thigh so that the femur is flexed, adducted toward midline, and gently internally rotated.) Other hip openers don’t seem to follow the rule of opening. We often externally rotate the hip to stretch the external rotators of the hip. Huh? The reason this works is because we typically flex the hip at the same time.
Use Your X-Ray Vision
To understand how hip openers work we have to picture the position of the muscle. Let’s picture the obturator internus muscle, a close friend of piriformis. It attaches from our sitting bone or ischial tuberosity to the greater trochanter of the femur, a bony outcropping on the side of the hip. We can feel both of these pieces of bony anatomy. Our ischial tuberosities can be felt when sitting, they are the bony bits under the flesh of our buttocks. Our greater trochanter can be felt by first finding the top of our pelvis by by placing our hands at our waist, firmly pressing in and down until we feel a ledge. This is our iliac crest. Slide your hands down and with your thumb you will feel a bony prominence that is the femur. You can feel it move by slowing rotating the hip in and out. So now we can feel the attachment points for the obturator internus, between the ischial tuberosity or sitting bone, and our femur. From this observation we can see that in a neutral position the muscle wraps around the hip. So if were to flex the hip, the ischial tuberosity scoops under thus increasing the space between the two attachment points and increasing the wrapping distance of the muscle – hence lengthening the muscle. This is why a simple squat (using the term simple lightly) can stretch our hip rotators and can be one of the reasons Westerners find it so challenging to achieve.
Opening Our Hips to Open to Possibility
Since there are many muscles in the hip with many functions depending on the demands we place on our body, keeping these muscles supple can help us in ways that may not seem obvious at first. Hip openers may help us attain a standing pose we’ve been struggling with, or they may help us get down on the ground easily to play with our kids or our kitten. Traditional yogic thought attributes many healing properties to hip openers from organ issues to sexual dysfunction. So if you are one of the groaners when hip openers are suggested, perhaps pause to wonder if they could be helping you in ways you weren’t even aware.
