Medical facts regarding breathing:  

• When the heart is deprived of oxygen it goes into spasms, therefore it is not surprising that shortness of breath and heart diseases are linked to one another.
• Cancer does not survive high levels of oxygen, it is anaerobic.
• There is a correlation between High blood pressure and poor breathing.
• Breathing controls the nervous system. When we don't breathe correctly the nervous system goes out of balance, which usually results in emotional issues such as anxiety and depression.
• Oxygen aids in the process of burning fat and calories, therefore promoting weight loss.
• If you don't breathe well - you won't sleep well and you won't wake up well either. It's important to treat any breathing problems (snoring among them) and start breathing correctly in order to set yourself free of this downward spiral.
• Almost every health condition and human activity can virtually be improved by correct breathing.
• Lung volume is directly connected to your life-span. It is important to take lung tests and keep track of what is going on inside your body.
• When you hold your breath it causes vasoconstriction (constriction of blood vessels) which leads to a sharp raise in blood pressure.
• Every minutes you breathe in the amount of air equivalent to 13 pints.
• Your lungs contain almost 1500 miles of airways, and over 300 million alveoli.
• Chronic oxygen deficiency in tissues is connected with coronary disease and heart attacks.
• Hypoxia, or lack of oxygen in the tissues, is the fundamental cause for all degenerative disease.
• Lungs are very delicate organs and are vulnerable to a range of illnesses, in which the most common are bronchitis and emphysema. This diseases are often caused by smoking.
• Lung cancer is often a result of smoking and it is the world's most common cancer. It is diagnosed in 1.4 million people a year!

   

• Inhaled air is approximately 78% nitrogen, 21% oxygen, about 0.04% carbon dioxide and 1% other gases (eg argon).
• Exhaled air is approximately 78% nitrogen, 16% oxygen, 4% carbon dioxide plus the other gases and an indeterminate amount of water vapour (which a waste product of respiration).
• The airways (trachea, bronchi and bronchioles) are lined with cells with hair-like projections called cilia. They also have mucus producing goblet cells. This mucus traps dirt, bacteria and viruses.
