Why does sitting hurt?

 

A regular chair is equipped with a solid full seat which directly applies pressure on the human body. Besides the buttock and thigh muscles, other parts of the body, which are not intended for sitting, are compressed as well, such as the anus, tailbone, pelvic bones and genitals. The pressure from the seat has destructive effects on these compressed parts and it is transferred through the tailbone into the spine, neck and the head. At the same time a regular seat does not provide a stable pelvic position, into which pressure from the upper part of the body is transferred through spine under certain angle. The change of the optimal angle between the pelvis and the spine leads to extreme muscle and ligament strain in the lower back region. This results in lower back and neck pain, headaches, hemorrhoids, fatigue and impaired alertness.

What to do and how to avoid pain

 

This analysis shows that if we want to completely eliminate all problems arising from sitting we have to eliminate the pressure applied on all of these critical parts of the body. It is necessary to transfer the pressure from the seat into the buttock and thigh muscles, which are intended for this purpose. At the same time we need to ensure stable natural position of the pelvis towards the spine so that the misalignment of compressive strength from the upper part of the body does not occur. Provided that compressive strength is directed in the right way, an immediate perceptible effect occurs and sitting becomes a pleasant and relaxing or working position. We simply sit in the right position employing those parts of the body which are intended for this purpose.

Virasana the “divine design” of the seat

 

The particular solution to an ideal seat follows from a basic yogic sitting pose on one’s own legs called “VIRASANA”. It is a relaxing body posture which is used to reduce lower back pain and overall fatigue. The anatomy of human calves creates an ideal seat, which does not apply pressure on the above mentioned critical points of the human body, which are strained during regular sitting. The tailbone, pelvic bones, anus and genitals remain free; the pressure is applied only on the buttock muscles and thighs. At the same time the pelvis is fixed by the heels and calves in the position equal to upright walking. A structural solution to an ideal seat for people is arrived at by applying these principles.

Application

 

 

Based on these facts, the ASANA series of sitting furniture has been designed. It is equipped with an optimal seat VIRASANA, which ensures healthy and comfortable sitting even when sitting for too long. When used regularly it eliminates existing health problems arising from sitting.
