Brain vulnerable to damage during oxygen deficiency. So it multiply oxygen into the body for the brain to stay awake, because of lack of oxygen can lead to disability to death.

Thursday (12/16/2010), the brain is very greedy for oxygen.Although the composition of the brain is only 2 percent of total body mass, this section spends a total of 20 percent oxygen demand. That is, one-fifth of the incoming supply of oxygen while breathing will immediately run to the brain.

Once the brain’s need for oxygen while the brain has little oxygen reserve. This also causes the brain vulnerable to damage under conditions of oxygen deprivation.

If you did not get oxygen supply within 3-7 minutes, brain cells will begin to experience death.

The human brain weighs an average of 1.4 kg (1,400 grams) and there are about 100 billion neurons, or there are about 70 million neurons per gram. These cells must receive a full oxygen for its maximum.

Man will be dying when the body can not get the oxygen needed to survive. So no wonder the help of oxygen is first given if someone passed out for the heart and brain still get oxygen.

Oxygen is little point in a person’s body healthy. Food and healthy lifestyle can increase the amount of oxygen in the body.

Likewise with breathing exercise can increase the transport capacity of oxygen into the blood. Sufficient oxygen can enhance the metabolic processes, because this excess oxygen level will enhance the ability of cells to use fat as energy.

Breathing exercises using the diaphragm would allow a person to inhale longer than the breath through the chest, so that more oxygen into the system.

By doing regular breathing exercises, then one can train the body to increase the amount of oxygen into the blood.

On the other hand the oxygen in the body has not been maximized due to air pollution, lack of sleep, closing the head while sleeping, smoking, chemicals, medicines and certain foods.

Lack of oxygen can cause many diseases such as brain stem damage (traumatic brain injury) and Down syndrome (mental retardation).

Children who experience a lack of oxygen when the baby is usually in a period of growth will have difficulty learning, inability to concentrate, problems of balance and coordination body. Autism and epilepsy also allegedly associated with oxygen deprivation at birth.
