Answer to Question 1
Proper breathing is vital to optimal health, as the process of inhaling air feeds life-sustaining oxygen to the lungs and, in turn, the cardiovascular system feeds it to virtually every part of the body, revitalizing organs, cells, and tissues. It's best to avoid a pattern of shallow, quick breathing in reaction to stress because this type of breathing restricts the body and brain from receiving the amount of oxygen required for healthy function. Instead, breathing fully and deeply has been shown to ease anxiety and pain, improve asthma symptoms, burn calories more efficiently, lower blood pressure, strengthen the immune system, and help people with diabetes control blood sugar.
Students who practice deep breathing meditation significantly increase academic learning and achievement. One study in particular found that college students who practiced deep-breathing exercises before an exam reported decreased levels of anxiety, nervousness, and loss of concentration.

These exercises have been used for centuries in the Orient and India to improve mental, physical, and emotional stamina.
