Qigong practices are designed to improve the flow of chi throughout the body, and some practitioners report experiencing a range of physical or emotional sensations as a result. One of the most common sensations of chi is a feeling of warmth, heat or tingling in the body, often accompanied by a sense of relaxation and well-being. Some practitioners report feeling a pulsing, vibrating, or magnetic sensation in specific parts of the body, or a sense of energy flowing through the body. With time and practice, many experience a heightened sense of awareness and a feeling of being "in the zone."
However, not all chi reactions are pleasant.
