Figure 9.15. Comparisons of postulated regional blood pressures in standing and various inverted postures. For each posture (from the left), the average arterial blood pressure (systolic/diastolic, over time) is estimated locally for the head, neck, chest and ankles.

We can gain insight into this puzzle and Gnd a possible solution to it b; comparing the inverted action pose with the shoulderstand. The distant-i between the heart and the neck, and between the heart and the head, ar almost the same in both postures, so any differences in blood pressure du to the pull of gravity should be minimal. But anyone who has compared th postures experientially notices two things about the inverted action pos< in the neck there is dramatically less local tension and pressure than in tl shoulderstand, and in the eyes, ears, and face, there is an increased sens tion of pressure. There is only one way to explain these findings easily—1 postulating that, compared with the classic shoulderstand, the invert* I action posture releases constrictions in the great vessels of the neck, whi in turn allows blood to course more easdy into the head.

The lifted shoulderstand has its own special effects on circulation (fi 9.15). With the shoulders elevated the heart is lifted even higher than in t shoulderstand, and this will increase the blood pressure in the brain i accordance with the height of the lift. You do not notice this so much if yi u are using a one-inch mat, but it becomes pronounced as you raise your; If higher. Lifted up five inches you feel a rush of pressure in the head whi- h is almost identical to that felt in the headstand.

The plow postures, with the feet touching the floor overhead, have si II a different effect on circulation. Here there is no pronounced drainage >f blood from the lower extremities, but once blood is in the abdominal reg n it will be recirculated quickly back to the heart. As far as effects in the ht d and neck are concerned, if your hamstrings and hip flexibility allow yoi o draw the feet overhead without lifting the chest very far off the floor fa n variation one of the plow), the heart will be just a little further off the fl< >r than it is in the corpse posture. The feet and lower extremities will not '>e very far up in the air, and the posture will affect blood pressure in the b d only mildly (fig. 9.15). But if you are flexible enough to take the plow o variation three by pushing the feet to the rear and flexing the n< k maximally, the expected effect on blood pressure in the head and neck ¡11 be similar to what we see in the shoulderstand (fig. 9.15).
