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. One can live without food for weeks,  and without water for days; but not without  breath, as it can cause death within a few minutes.With each breath we exchange carbon dioxide from inside our body 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.

* It helps to get rid of waste products and toxins from the body.

Breathing is a simple and obvious act, and we often take it for granted ignoring the effect it has on the 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.

A large number of people breath incorrectly and are not even aware of it. Instead of breathing deeply to brign air down to the bottom of the lungs, where the richest blood supply is, people breath in a shallow manner that bring air only into the uppermost part of the lungs.

What's wrong with the way we breathe?

Often, our breathing is too shallow and too quick. We neither take sufficient oxygen nor eliminate carbon dioxide completely. As a result, body becomes oxygen starved and a toxic build up occur. Every cell in the body requires oxygen and our level of vitality is a product of the health of all the cells.We should breathe slowly and deeply. Quick shallow breathing result in reducing the immune system, premature ageing and other factors.Infact most of our energy requirements come not from the air we breathe not from food. By purifying the blood steam, each and every part of the body benefits as well as the mind.

The role of breathe is very important in practice of Yoga. First we need to understand why breathing is incorporated in the practice of yoga. The breath is prana or vital force. The requirements of oxygen or pranic energy for our body changes depending on our action. When we do exercise, more oxygen is required and breathing becomes faster and with force. When we relax the need for vital energy is lower and breathing becomes relaxed and deep.

Mental activities also affect 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 mid-body complex. The exhalation can be used for relaxing and removing the stress from the mind-body complex.

Benefits of deep breathe

The first rule for correct breathing is that we should breath through the nose. But quite often, people breathe through the mouth. Breathing through mouth can adversely affect the development of thyroid gland. It can retard the mental development. The nose has varied defence mechanisms to prevent impurities and excessive cold air entering the body. We should breathe slowly and deeply through the nose.

Deep breathing produces the following benefits.
