Kapalbhatti is form of Pranayama, which means (__ampersandsignbdquo;breath of life?). This exercise helps to regulate and control breathing. It is useful in clearing of mind, weight loss, diabetes, it improves the quality of life in people with heart diseases and prostrate enlargement. This procedure uses excess inhaled air to flush the blood vessels in the heart and clear them of nascent block. It involves taking normal breaths, diaphragm and abdominal muscles are to be moved violently and the air is exhaled with that movement. This is done for 2 minutes and Reaction times are recorded before and after the procedure. During normal breathing, we just take shallow breaths, and we don?t fill our lungs to capacity. Shallow breath causes excessive weight. Kapalbhatti teaches us how to take deep breath which increases oxygen supply to body and removes waste products. Continuous inhalation of oxygen and expulsion of carbon dioxide converts the venous blood to oxygenated blood. The heart__ampersandsign#39;s function to pump blood to the lungs is sub-served by the breathing technique. The heart is given extraordinary rest. Hyperventilation washes out carbon dioxide which leads to central vasoconstriction that leads to a filling of emptiness in the head. This possibly explains, scientifically why kapalbhatti cleanses the head. This is the reason we ventured to see reaction times in our study.
