Benefits of Inversion
Gravitational power has a big impact on a vertical circulation of blood in human body. The most affected are veins below the heart.
Deoxygenated blood is pushed towards the heart and lungs mainly by the contractions of the muscles. This works perfectly, when a person does mostly physical work. But todays typical person has a sedentary job, and in that case, the pressure generated by the muscles is not big enough. This leads to the cumulation of blood in lower limbs and the stomach area, which may lead to organ malfunction.
Persons, who work mostly with their brain, are in a big need of oxygen supplies in their head. But the arteries in the above-heart parts of the body are affected by the same problem as veins, thus leading to lower amount of oxygenated blood travelling through the brain.
The upright position is also the cause of the shift in the insides (descent of stomach, bowels ...) which may lead to functionality issues. That's why even yogis logically stress the importance of the inverted position, which almost immediately removes the drawbacks of the upright position.
The inversion table has a great impact on lots of human body parts.
