Scientific experiments

Various experiments have been conducted to measure the changes that occur within the body during the practice of sirshasana. These confirm scientifically what we have discovered from personal experience.

X-rays taken during the practice of sirshasana have shown a considerable shift of the diaphragm, changes in the longitudinal and transverse dimensions of the heart, and widening of the arteries and veins leading to and from the lungs, especially in the upper lobes. The significance is that more blood is travelling to and from the lungs, increasing oxygenation. The upper lobe which usually is not well oxygenated by a normal breath, is washed free of stagnant blood.

The tests clearly indicate that the amount of air breathed per minute (minute ventilation) during the performance of sirshasana was considerably reduced. The frequency of respiration (the number of breaths per minute) was lowered. Oxygen consumption by the tissues increased and the amount of oxygen exhaled was less, indicating that the transfer of oxygen to the blood is greatly increased.

There was an increase in the leucocyte (white blood cell) count, implying that the body's ability to withstand and resist infection is increased as the white blood cells are used to destroy bacteria and other foreign objects in the body.

These tests are significant and apply if the individual is completely relaxed. If the practitioner is tense or stressed while performing sirshasana, then it is possible to obtain contradictory results.

From these experiments we can conclude that sirshasana allows for a greater possibility of adaptive mechanisms in respect to circulation and respiration.

In the future, no doubt, more intricate experiments will be carried out to record and map out the actual blood flow changes in the brain; how the blood flow to the pituitary and pineal is modified and how it improves their functional efficiency; how other organs of the body are influenced and so forth. The influence of sirshasana on brain waves would also be an interesting scientific experiment. There is much scope for these kinds of tests and they would put the physical benefits obtainable from sirshasana on a firm scientific basis.

The Chakra Checklist

The chakras are described as being aligned in an ascending column from the base of the back to the top of the head. New Age practices frequently associate each chakra with a particular color.
