The Element of Air
Air is one of five basic elements of life viz. Air, Water, Earth, Fire & Sky. As I discussed in my article “The Human Body : Five Basic Elements” in my another website, www.healthwithoutmedicines.com , the human body as well as the universe is composed of all these five elements. However, in the present article, I am writing about element of air exclusively.
Air : Defined
In pure physical terms, air is the name given to atmosphere of earth, used in breathing and photosynthesis. Dry air contains (by volume) 78.09% Nitrogen, 20.95% Oxygen, 0.93% Argon, 0.039% Carbon Dioxide plus small amounts of other gases (trace gases) and water vapors of roughly 1%. We know that the air content and atmospheric pressure varies at different levels of atmosphere; the air suitable for survival of plants and animals ( including humans) is only available in troposphere; the lowest portion of earth’s atmosphere
The Nitrogen Cycle
Nitrogen occurs in all living organisms. The Nitrogen Cycle describes movement of the element from air into biosphere and organic compounds, then back into the atmosphere. The human body contains roughly 3% of Nitrogen by weight. Nitrogen is an essential building block of amino and nucleic acids, essential to life on earth. The human activities such as fuel consumption, use of artificial nitrogen fertilizers and release of nitrogen into the waste water, are affecting the Global Nitrogen Cycle.
Atmospheric Nitrogen ( which is about 78.09% as mentioned above) must be processed or fixed to be used by the plants. Some fixation occurs in lightning strikes, but the major fixation is done by free-living or symbiotic bacteria. Hence, the importance of saving the environment from pollution.
Carbon Dioxide & Oxygen
Elemental Oxygen is produced by cyanobacteria, algae and plants. It is used in cellular respiration for all complex life. Free oxygen is too chemically reactive to appear on earth without photosynthetic action of living organisms, which use the energy of sunlight to produce elemental oxygen from water.
As part of Carbon Cycle, known as photosynthesis, the cyanobacteria, algae and plants absorb carbon dioxide, light and water to produce carbohydrate energy for themselves and release Oxygen as a waste product. Carbon Dioxide is also the bye-product of metabolism in human body and combustion; emitted from volcanoes, hot springs, and geysers; and freed from carbonate rocks by dissolution.
Oxygen : the Basis & Health-Keeper of Human Life
As I told in my article, “The Quantity & Quality of Oxygen” published in my another website www.healthwithoutmedicines.com , the oxygen is not only the basis of human body, it is the health-keeper of our body. Ancient scholars rightly viewed air as the Life-force. Now we know through physiology, the importance of the supply of oxygen to our body. The lungs are the main instruments or organs of human body responsible for supply of oxygen through the breathing process. Keeping in view the importance of this function of lungs, I have devoted this website www.healththroughdeepbreathing.com to focus on breathing exercises and breathing techniques in maintaining or regaining health through natural means. In my next article, I will concentrate on the breathing process prior to writing articles on various breathing exercises and practices.
As I said earlier, I am not a doctor or a health care professional. My articles are the result of my personal experience and are for information and educational purpose only. The consultation with a doctor is desirable and recommended. In health care, the choices made by the individual are very important and only the concerned individual is responsible for his or her choice.
