Oxygen is one of the most important and abundant elements on Earth. About 46 percent of the Earth’s crust is oxygen. It is colorless and odorless and makes up about 20.95 percent of the atmosphere by volume. Oxygen exists in water as part of water molecule, in the atmosphere as a gas, in the Earth’s crust and in an enormous variety of rocks and minerals. It can also be released from the plants through photosynthesis. Moreover it is very essential for life and is part of almost every biological molecule in our bodies. Without it, human life simply could not exist. Humans can live for weeks without water, and go without food for months, but without Oxygen, life could only carry on for a matter of moments.
About 90% of the body’s life energy is created by Oxygen. In fact, all functions of the body are regulated by Oxygen. Our brains process billions of bits of information each second, thanks largely to Oxygen. Other important benefits are that Oxygen appears to dramatically help nervous system response, promote brain function, relieve mental fatigue and restore mental clarity to optimal levels. This is due to the electrical conductivity of Oxygen. Furthermore, the human body must have oxygen to convert fuel like the carbohydrates, fats, and proteins from our diet into heat, energy, and life. Through the process of metabolism, which is similar to combustion, fuel and oxygen are consumed, while heat and energy are generated.
The Essay on Determination of Dissolved Oxygen In a Water
INTRODUCTION In an alkaline solution, dissolved oxygen will oxidize manganese(II) to the trivalent state. 8OH-(aq) + 4Mn2+(aq) + 2H2O(l) －－＞ 4Mn(OH)3(s) The analysis is completed by titrating the iodine produced from potassium iodide by manganese(III) hydroxide. 2Mn(OH)3(s) + 2I-(aq) + 6 H+(aq) －－＞ 2Mn2+(aq) + I2(aq) + 6H2O(l) Sodium thiosulphate is used as the titrant. Success of the method is ...
When the body is deprived of an adequate oxygen supply, even for a short period, various organs and processes in the body begin to suffer impairment from oxygen deficiency. This condition is known as “hypoxia”. It has been shown that any type of stress to the body will bring oxygen deficiency. TOXIC STRESSES (toxic environment), EMOTIONAL STRESS, PHYSICAL TRAUMA (reduces circulation and the subsequent oxygen supply) and INFECTIONS are the four main stresses in today’s modem society. Surprisingly, the hypoxia can cause an individual to a variety of degenerative illnesses, such as, digestive disorders, over all bodily weakness, muscle aches, depression, dizziness, irritability, fatigue, memory loss, irrational behavior, chronic hostility, circulation problems, poor digestion, acid stomach, lowered immunity to olds, flu, infection, bronchial problems, tumors and deposit build ups, bacterial, viral and parasitic infections, and even cancer (which is caused by the replacement of normal oxygen respiration of the body’s cells by an anaerobic cell).
Generally, inhaling excess amount of Oxygen is good to health. However, when oxygen exists as triatomic molecule called ozone, O3, it then becomes quite destructive to materials and harmful to our lung tissue. During periods when there is an excess amount of ozone in the air, which is about more than 120 parts per million parts of air, it is usually suggested that older people and children not engage in any severe physical activity that would increase the deep inhalation of ozone. The chief source of ozone in the lower atmosphere is called “bad ozone” which is the photochemical destruction of nitrogen dioxide from cars. In contrast, the “good ozone” exists in the upper layers of the Earth’s atmosphere. It shields the surface of the Earth from UV radiation emitted by the sun.
As a result, Oxygen is indeed an important key to good health. Torn Valentine, author of “Medicine’s Missing Link”, says, “It would be interesting to compare the amount of Oxygen in a strong, healthy person with the amount in a chronically ill individual.”
The Term Paper on Meditation Body Stress 2004
Meditation is defined as a mind-body technique, which practices awareness, and induces tranquility in order to connect the mind and the body. It is also described as "mental fasting," implying clearing and cleansing of the mind by the absence of distractions and negative emotions (Leikin, 2003). It has shown to benefit its users psychologically, physically, as well as spiritually. Meditation works ...
