The value of breath can be quickly understand by comparing it to the other primary mechanisms that the human body requires to sustain life such as food and water. The amount of time it takes for the body to die if air, water and food are not available reveal the healing power that each one has.
Breath: Approximately 3 – 5 Minutes Water: Approximately 3 – 5 Days Food: Approximately 4 – 6 Weeks
As you can see, the level of energy that breath provides the body to keep it alive is incredible. The body will decay until the point of death in minutes without air.
Yoga breathing which is known as pranayama yoga is the first step toward re-orienting and improving the functioning of your mind and body by learning to optimise the breathing process. The Yogis were the first to discover the importance of oxygen and breath control and devised an exact science of breathing. Pranayama implies correct breathing and breath control. The purpose of yoga breathing exercises is to supply the body with oxygen and cleanse it of carbon dioxide and other toxins.
3 STAGES OF BREATH:
Inhalation which is called (puraka), fills the lungs with air and stimulates the whole body.
Retention, is called (kumbhaka) during retention the bodies temperature is raised and the oxygen is absorbed.
Exhalation, is called (rechaka) here the diaphragm is returned to its original position and toxic air is released into the atmosphere.
