Human's life begins with breathing in, maintains by breathing and ends with exhalation. Regulating the breathing allows human to change his/her condition. Indian sage X-XI c. Horaksha claimed the breathing to be a fire which burns the consequences of the actions: inhalation gives strength, controls and clears the body, breathholding makes thoughts clear and gives a long life, and exhalation has cleaning functions. According to the Indian yoga, breathing exercises influence on life energy ( ci or chi - in Chinese, ki - in Korean and Japanese, thi - in Vietnamese). Among most people its activity is poor, the circulation is chaotic or blocked that causes diseases, which can be omitted by the breathing regulation. The objects of the regulation are the way of breathing: through the mouth or nose (preferable), through one nostril, by turns: through left or right etc; the phase (inhalation, exhalation, breathholding, and pause); type (upper, intermediate, lower); duration and intensity of phases, rhythm, tempo. Inhalation increases the cortex tone, exhalation reduces it.
