What is the primary characteristic of inversions in yoga?

Inversions in yoga refer to any pose where the heart is positioned higher than the head. This unique positioning creates a variety of benefits, including increased blood flow to the brain, stimulation of the lymphatic system, and a sense of mental clarity and rejuvenation. Inverted poses such as headstands, handstands, and shoulder stands are examples where this characteristic is prominently displayed.

When the heart is higher than the head, it encourages a shift in perspective both physically and mentally. This not only enhances circulation but can also invoke feelings of grounding and stability through balance and strength, challenging the practitioner to engage their core and maintain alignment.

In contrast, the other options do not accurately describe inversions. While it is true that the position of the heart can vary in different yoga poses, in the context of inversions, it specifically refers to the heart being elevated above the head.
