High Blood Pressure and Inversions

High Blood Pressure and Inversions

The practice of Yoga poses (Hatha Yoga) offers tremendous health and wellness benefits, but certain health conditions require important modifications and omissions of specific asanas. High blood pressure is a serious health condition that generates many possible contraindications especially in Yoga postures that invert the head below the level of the heart.

High blood pressure (or hypertension) is the occurrence of abnormally high arterial blood pressure at resting state. High blood pressure can result from a variety of factors but is commonly associated with atherosclerosis (a common arterial disease in which raised areas degeneration and cholesterol deposits form on the inner surfaces of the arteries), poor dietary habits, lack of physical activity, and high proportions of body fat.

High blood pressure is a result of arteries having poor blood flow. This resistance to flow requires the heart to pump more vigorously in order to circulate the blood (oxygen and nutrients) to all the cells of the body. This extra effort placed on the heart has a wearing effect on heart tissues and places a greater amount of fluid pressure against the walls of blood vessels.

How Does High Blood Pressure Affect Yoga Poses?

When we invert the body such that the head is below the level of the heart, there is a tendency for blood to pool into the head. This pooling of blood into the head greatly increases when one also elevates the lower body and legs above the level of the head. When we do Yoga poses and other forms of exercise, there is an increased demand for oxygen by muscle cells.

The way that the body meets this increased demand for oxygen is by increasing heart rate and blood flow. So if we invert or place the head below heart-level during Yoga poses and other exercises, not only is there a pooling of blood in the head, there is elevated blood flow and pressure coming into the cranial region.

Normally, the body is adapted to handle blood pooling and mild pressure in cranial blood vessels. But if one already has elevated blood pressure at resting states, the sudden inversions in Yoga can add to the elevated blood pressure, thus generating pressure that is enough to damage delicate blood vessels in the brain. In severe cases, high blood pressure combined with inversions may cause blood vessels to hemorrhage.

Another area of awareness required, when high blood pressure is present, is the process of breathing. When one holds the breath while doing heavy exertion, blood pressure dramatically increases. This contraindicating effect is called the Valsava Maneuver. Many people are familiar with hearing fitness trainers saying “breath out” during the exertion stage of an exercise repetition.

Again, this breathing pattern not only keeps a steady flow of oxygen moving to the tissues but also has physiological benefits in preventing negative pressure occurring in heart and brain tissues. Therefore, when one has high blood pressure, holding the breath in Yoga poses or holding the breath in specific pranayama (breathing exercises) should be avoided.

If you have concerns about having high blood pressure, consult your physician. If you are diagnosed with high blood pressure, make certain you tell every Yoga teacher with whom you practice. Your Yoga teacher can then offer the appropriate modifications and variations in Yoga postures and pranayama.

Poses to Avoid When One Has High Blood Pressure

In simple terms, avoid Yoga poses that position the head below heart level especially when the practice or pose is vigorous. Here are examples of complete and partial inversions:

  • Salamba Sarvangasana (Shoulder stand)
  • Shirshasana (Head Stand)
  • Adho Mukha Svanasana (Downward-facing Dog)
  • Setu Bandhasana (Bridge or Spinal Lift pose)
  • Uttanasana (Standing Forward Bend)
  • Prasarita Padottanasana (Wide Leg Standing Forward Bend)

Having high blood pressure should not prevent one from doing Yoga. By understanding the degree of the health condition and by following the recommendations of physicians, one can still have a fulfilling Yoga practice with a wide range of Yoga poses.



Yin Yoga Poses

This article is an exploration of 10 Yin yoga poses. Yin is a style that is practiced by holding poses for a long time in a relaxed state. Yin stands in contrast to other contemporary styles of yoga, such as Vinyasa or Hatha, which generally move the practitioner from pose to pose quickly. Yin yoga ‘asana’, the Sanskrit word for poses, are practiced by following the three principles that Bernie Clark explains in Yin Yoga with Bernie Clark.

Three Principles of Yin Yoga

  • Principal 1: Play with your edge
  • Principal 2: Stillness
  • Principal 3: Hold for Time

Play With Your Edge

Yin is a lunar practice, which tends to be healing and cooling. Unlike solar practices such as sun salutations, yin does not call for heating postures, breathing styles, or sequencing. Therefore the muscles are typically not warm throughout a Yin practice. Entering into poses with cool muscles requires special attention to the first edge.

The first edge is found by gently getting into the shape of a pose and noticing where the body naturally wants to stop. Yielding the natural limitations of the body prevents injury. There should be no pain at the first or any other edge, yet there may be some discomfort. Discomfort without radiating pain is a sign that the connective tissue around the joints is stretching. Reasonable discomfort is a gateway to more flexibility and greater range of motion. Props can add additional comfort and accessibility to yin yoga poses.

You may experience strong physical sensations during a Yin practice such as heat or discomfort. Finding the first edge is a method of exploring the strong sensations and sitting with them. When yoga asana is briefly mentioned in the Yoga Sutras of Patanjali, they are prescribed to be Sthira sukham asanam, or done with steadiness and ease. Steadiness points to the second principal, stillness, which is explored later in the article.

About 30-60 seconds into a pose, or if and when the body shows signs of being able to go deeper, it is safe to move to the second edge (or third or forth). It is important that the body, not the ego, give the signal to deepen. This humble practice never asks the yogi to prove or force anything. There is no need to try to “achieve” or to look a certain way. Gentleness, acceptance and honesty are critical in a yin practice. If the body starts to tighten, it’s a sign to slowly come out of the pose.

Stillness

Classical yoga was practiced as a means to still the mind for meditation. Sitting still in yin yoga poses lets the contemporary yogi dip their toes into the waters of deep meditation. One exception to stillness is when the body opens to a new edge. With the awareness that the body is ready to deepen, Yin yogis consciously move deeper and return again to stillness and breath. Another exception to stillness is the awareness of pain. In response to pain, it’s time to come out of the pose slowly.

Hold for Time

The third principal is to hold the poses for time. Poses can last anywhere from one minute to longer than 15 and in general are done for 5-10 minutes. Using a timer tells you how long you are staying still, which can be a way to gauge stillness from practice to practice. A timer can also ensure that both sides of the body get the same amount of time, which results in feeling delightfully balanced. The breath can continue to deepen the longer a pose is held. The lungs can expand seemingly forever. Counting breath is an interesting way to observe the expansive nature of the breath, which becomes possible during long holds. Profound experiences become accessible only when conscious and deepening pranayama is practiced.

Breathing expansively while remaining still presents the practitioner with what is rarely otherwise observed: the quiet inner dance of consciousness, an inner world so rich and mysterious, it is invisible most of the time. Holding (still) for time never seemed so tempting.

10 Yin Yoga Poses

1. Chest and Shoulder Expansion

Sit cross-legged, your right side adjacent to the wall, reach your right hand back so the palm is flat against the wall at about shoulder height. Scoot your right hip in closer to the wall if you feel you can safely tolerate more stretch. Once the shoulder feels settled, bend the arm so you have the palm directly above the elbow at the height of your gaze. Sit and breathe for several moments. If you feel you can safely deepen, allow the left hand to come beside and slightly behind your left hip and press fingertips into the floor. Lift and open your chest. Slowly drop the left shoulder down and perhaps the chin and gaze point follow. Stay for 1-5 minutes breathing gently.

 

2. Lower Back Pose

Sit on a cushion if you have tight hamstrings or flat on the mat for more open hamstrings. Let the legs extend and relax so that the feet flop out gently to their respective sides. Knees can be slightly bent. Pressing the fingertips downward into the ground beside the hips, lengthen the heart higher in contrast. Then tuck the chin into the chest. Let the upturned palms fall to the outside of the thighs near the knees. Allow the upper spine to round. For your second edge, the hands may move down the legs closer to the ankles. Remember not to strive or do too much. Stay and breathe 1-5 minutes.

 

3. West-Facing Pose

This pose just like the lower back pose, sitting up legs relaxed and extended. Place one bolster over your thighs. Lift though the chest as you inhale and as you exhale fold forward and down, hinging from the hips so as to keep length in the low back. If you are not able to lay upon the cushion, add more props until you can easily lay your chest and face on them. Find your first edge. At this time you may determine to remove or reduce the props so that you can go deeper. Stay in the pose for 1-5 minutes. Note, this pose is called “west-facing” because it is cooling, like the setting sun, which sets in the west.

 

4. Wide Leg Child Pose

On your mat, add cushion beneath the knees using a blanket or towel. Bring the knees as wide or wider than the mat and big toes to touch or towards one another. Press your hips back toward the heels and walk your hands forward as you fold from the hips. Imagine a gentle anchor keeps the hips downward and the low back spreading wide. From there, stretch the arms, chest and head forward and down. If the head cannot touch the floor, put a block or folded blanket beneath it so it can rest. You may prefer to rest upon the forehead or to turn the head to one side and then the other. Let your arms and hands relax into the floor. Notice your edge and deepen if and when it feels right. Come out if the knees start to bother you, moving slowly. Practice for 1-5 minutes.

 

5. Wide Leg Child Pose, Thread the Needle Variation

From wide leg child pose, slightly raise the head and walk the right hand back. Thread the right hand under the left until the right shoulder is on the ground and put the right temple on the floor. Repeat on the left side. Practice 1-5 minutes on each side.

 

6. Lizard

Come to your hands and knees with a folded blanket under the knees for padding. Bring your right foot forward so it is just to the right on the right hand, make sure your shoulders are over the wrists. The right knee stacks over the right ankle so your shin may feel as though it is moving forward in space. If the right knee pops out to the right, redirect it over the ankle, pressing down into the right foot and imagine pressing the shin forward.

If needed, bring your hands up on blocks, lift through the chest, curl the left toes under and squeeze the left leg so the thigh lifts off the ground. This will cause the thigh to rotate internally, which means the alignment is now safe for deepening. Now , bringing the left knee down onto the blanket and then flatten the top of left foot into the mat. You may stay like that or bring your elbows onto the blocks to deepen. You may end up with no blocks, elbows on the mat beneath the shoulders or you may end up staying high on blocks. Honor where the body needs to go and remain for 1-5 minutes before repeating on the other side.

7. Pigeon

Place a flat bolster horizontally across the mat or a folded blanket about halfway down the length of the mat. Place both knees on the bolster. Bring the right knee forward of the cushion in front of the right hip and the foot toward on left side of the mat. Place the palms on blocks beneath the shoulders and bring the left leg back so that the thigh and top of left foot are pressing into or towards the floor. Let the pelvis be supported by the cushion. You may stay upright, opening the chest, or choose to ease yourself down, perhaps deepening to the point where your head rests on blocks or on the floor. Remain in the pose 1-5 minutes and repeat on the other side.

8. Supported Reclined Butterfly

The use of props to recline makes this supportive and relaxing. To do so, place a block the tall way and another the short way so they make an L. Lay a bolster or supportive cushion over the blocks so that it a slanted toward the floor. Place yourself with your back against the lower part of the cushion with the souls of your feet touching. To keep the feet together and to allow the hips to relax, use a strap or a long rolled blanket to wrap the feet.

9. Supported Gentle Fish

Place a block at medium height near the top of the mat. Sit so the block is behind you with the legs extended and relaxed. Lay your back over the blocks so they land between your shoulder blades boosted your heart up. Let your head relax back onto a block, making sure the neck is supported. Allow the arms to pour open and drip into the floor on either side. Breathe into the heart and let the body seep down onto the props. As your edge moves, notice the chest may boost higher. Remain 1-5 minutes.

10. Corpse Pose/ Savasana

Lay on the mat on your back. Let the arms and legs relax. Arms by your sides, feet slightly flop out. If your lower back is uncomfortable place blocks or a cushion under the knees. Stay as long as you wish. Let go of doing and drop into being.
