From the moment of birth to death we are breathing. Our life is measure by breath .Breath is more important to us than either food or water. we can live without food for weeks and without water for days, but without breath ,we will die within a few minutes .With each breath we exchange carbon dioxide from inside our bodies for oxygen molecules from the surrounding air.
Breathing is important for two reasons:
* Its supply of oxygen to various organs of the body, which is vital for our survival.
* The second function of breathing is , to get rid of waste products, toxins from the body.

Breathing is so simple and so obvious. We often take it for granted; ignoring the power it has affect body, mind, and soul. With each inhale we bring oxygen into the body and spark the transformation of nutrients into fuel. Each exhale purges the body of carbon dioxide, a toxic waste.
Breathing also affects our state of mind. It can make us excited or calm, tense or relaxed. The rhythm of our breathing varies according to our activities and our feelings. It quickens with physical exertion or emotional upset, it slows down during sleep or periods of relaxation.
The majorities of people breathes incorrectly and are not aware of it. Instead of breathing deeply, brining the air down to the bottom of the lungs, where the richest blood supply is, and the breath is very shallow, only brining the air into the uppermost part of the lungs.

What's wrong with the wat we breathe?
Our breathing is too shallow and too quick, we are not taking sufficient oxygen and we are not eliminating sufficient carbon dioxide, as a result, our bodies are oxygen starved and a toxic build up occur. Every cell in the body requires oxygen and our level of vitality is just a product of the health of all the cells.
We should breathe more slowly and deeply. Quick shallow breathing results to reduce the immune system, premature ageing and other factors.
Infact most of our energy requirements come not from food but from the air we breathe. By purifying the blood steam, every part of the body benefits as well as the mind.

First we need to understand why breathing is incorporate in yoga practice. The breath is prana or vital force. Our body requirements of oxygen or parnic energy are changing depending on our action. I f we exerci8se then more oxygen is required so breathing becomes faster and with force but if we are relaxing then this need of vital energy is lower and breathing becomes relaxed and deep. Also the mental activities affect the breathing. So for physical, mental function, breath is very important.
Generally every yoga session should have a positive resolve, may it be for better physical or mental health. The positive resolve should be integrated with inhalation process, as the air or prana entering into the body affects the entire body _mind complex. The exhalation can be used for relaxing and removing the stress from the body &mind complex.
