Gradual development of problems arising from sitting – What others won’t tell you

Familiarize yourself with the surprising results of the study which logically and clearly defines how pain and health problems arising from sitting develop gradually.

 

Common undesirable effects, such as discomfort, pain, health problems and fatigue, occur when sitting on regular, health and ergonomic chairs for a long time. Even despite their perfect design, materials and ingenious mechanisms.

 

Each producer offers their customers a guaranteed ideal solution to the elimination of problems arising from sitting. A suffering customer can encounter with a wide range of recommendations and ideas of how to avoid pain and health problems arising from sitting.

 

It is really difficult to choose from them, if you are not a specialist in ergonomics. The existence of so many various solutions, which solve the problem arising from sitting only partially, points to the inability of ergonomists, designers and producers to fully understand the sitting phenomenon.

 

We offer you a complex analysis of how your problems arising from sitting on regular chairs develop gradually in chronological order of their actual development. The so called DOMINO effect occurs when sitting and individual problems are logically interrelated.

 

The first phase ................... where it begins:

 

The beginning of sitting 10 - 20 min.

 

1. Discomfort in the region of 2 lower pelvic bones, between which the anus is located, begins.

 

2. Then the pressure on genitals begins within several minutes.

 

The course of sitting 20 - 40min.

 

3. This imperceptible slight discomfort causes subconscious “bending aside” i.e. the person, who is sitting, starts to lean sideward and they subconsciously try to shift the pressure from one side of the lower part of the body to another.

 

 4. By doing so, the pressure on the points on which we lean increases; actually twice the amount of pressure is concentrated on them.

 

5. The person is forced to subconsciously take the “relaxing position” - they slide forward on the seat and they take some kind of a half-lying position.

 

6. At this position the seat comes into contact with the tailbone on which unnatural and intense pressure is exerted.

 

The course of sitting 40 - 120 min.

 

7. At this point of time the discomfort increases and the tailbone starts to generate pain. At the same time when the person leans or slides down the pelvic bone changes its optimal position and subsequently a front to back misalignment of compressive strength between the spine and pelvic bone occurs.

And of course, at the same time the problems in the anal region (sweating, irritation, inflammations, … hemorrhoids…) and pressure applied on the genitals keep being generated.

 

8. Due to constant pressure from below and an attempt to avoid discomfort, the pelvic bone keeps changing its position and angle to the spine.

 

At this stage it is necessary to note that the first phase of the development of problems has nothing in common with the backrest or its position and the position of the seat or its dynamic properties or adjustability options.

It is very simple...

These problems arise due to a full seat and the pressure it applies on the human body. Paradoxically almost no attention is paid to this in common ergonomics.

 

 Second phase ................... where it ends:

 

The course of sitting 120 – infinite number of minutes

 

9. At this stage the upper part of the body becomes affected, since its weight is transferred through the spine into the pelvic bone. The pelvic bone represents a static solid beam, into which weight from the upper part of the body is transferred through the backbone. An optimal angle is an angle when the pressure from the weight of the head and body is transferred linearly from the head through the cervical spine into the spine and then into the pelvic bone (just like the upright walking position).

 

10. The change of the optimal angle in any direction leads to the misalignment of compressive strength and extreme strain of ligaments and muscles in the lumbar and neck regions which hold it all together.

 

11. If it lasts for a long time it results in intense nape, shoulder and lower back pain.

 

12. This subsequently generates various chronic deformation of ligaments and the body skeleton, etc.

 

The first phase is the real cause of the problem and the second phase is only a consequence of the problems arisen in the first phase.

And it is in the second phase where all present-day chair producers start their solutions trying to put the spine and the pelvic bone back into the correct position. All existing world-wide known ergonomic studies ignore the first phase completely and testify to the misconception of the real cause of problems arising from sitting.

They are trying to solve the consequence not the real cause.

And therefore the majority of the chairs developed based on this knowledge do not work or work only partially.
