When we adjust the position of the body, as we often do in yoga practice, the head sometimes goes below the heart. When this happens, gravity pulls blood into the head, raising the blood pressure. Our body adjusts by decreasing the blood pressure in the head to protect the brain and face. This effect can be both positive and negative depending on our health and our bodies’ ability to adjust the pressure.
If we are healthy, the shifting of the blood pressure up and down can be beneficial, teaching our systems how to respond to changing conditions. This is why healthy people should put the head below the heart.
If we have high blood pressure we must be very careful. Whenever the head goes below the heart, it is possible that the blood pressure will get dangerously high before the body responds. Or the body may not respond effectively and let the blood pressure stay too high for too long. So those of us with high blood pressure should take care when putting the head below the heart.
We can do gentle “inversions” by bringing the head even with the heart or only slightly below. This can be done in forward folding positions and kneeling positions like Half Tortoise or Child’s Pose.
