The "civilized" man has created a habitat, very different from the natural one, whose surfaces where he usually lives (flat ground, chairs, desks) are completely unfavorable for human biomechanics and physiology. This artificial environment inexorably entails psycho-physical problems including, starting from the first steps, postural alterations.
What the brilliant French physiotherapist Francoise Mezieres had guessed, before the advent of postural analyzes with specific and modern electronic devices, has been fully confirmed by the latter:"The" lumbar hyperlordosis is always primary ". In fact, studies show that our organism, our postural and balance system, react to the flat ground by creating a lumbar hyperlordosis. It is usually "spread" along the entire lumbar spine (classic case of lumbar hyperlordosis), therefore compensated, consequently, with an excessive and wide opposite arching at the dorsal level (dorsal hyperkyphosis) and a straightening of the cervical spine (this " the latter is formed as a reaction to "cervical hyperlordosis, which would be consequential to the first two curves, but which would not allow us to look at the horizon, the primary factor for the organism), or, in the case of the (false)" disappearance of lumbar lordosis " or its "straightness", concentrated between the "last lumbar vertebrae and the first sacral vertebrae (L5-S1) which consequently corresponds to an acute and excessive opposite arching at the dorsal level and, again for the same reason as in the first case, a straightening of the cervical tract. The posterior angle formed by L5-S1 considered physiological is approx. 140 °.
Furthermore, lumbar hyperlordosis is often accompanied by rotations of the pelvis in the transverse plane
On the basis of various parameters, including certainly the genetic makeup, the compensations imposed by "lumbar hyperlordosis are nothing but" forcing "that our brain, through the postural tonic system, is forced to ask the connective system, muscles, tendons, ligaments, joint capsules, joints, nerves, organs, etc., in order to obtain a posture as stable as possible on a ground that is not congenial to us. Our musculoskeletal system and our postural control system have in fact evolved, in millions of years, to allow us to better adapt to the natural terrain, which is uneven (it is no coincidence that our foot has 33 joints). We have seen that man represents a cybernetic system or a system capable of self-regulating, self-adapting and self-programming. On the basis of the information received moment by moment from the external and internal environment, he constantly tries to best pursue the goal of homeostasis (condition of dynamic equilibrium of the organism). Although it represents the cybernetic system par excellence, it encounters, like all systems of this type, an adjustment / programming error tending to infinity the more the input variables tend to zero and vice versa. In other words, the more the information environmental conditions that our organism receives are numerous and diverse, the more it succeeds in pursuing a fine and correct regulation of its functioning. natural.
"The flat terrain is an" invention of the architects. It is "suitable for machines, not for human needs (...) If modern man is forced to walk on the flat surface of asphalt and pavements (...) he is alienated from his natural and primordial contact with the earth. A crucial part of his being atrophies and the consequences are catastrophic for his psyche, for his balance and for the well-being of his whole person "Friedensreich Hundertwasser (Viennese architect, painter and philosopher), 1991.
The current lifestyle is also increasingly "unnatural", often based on a sedentary lifestyle, stress and inadequate nutrition.
There sedentary lifestyle adds to the postural problems the decrease of proprioception and motor skills with what follows. In addition, as discussed in the paragraph on relaxation, the frenetic rhythms of modern life impose an excessive use of the exteroceptive senses, sight and hearing, which also leads to a gradual decrease in the "feeling" of our body (bodily despair) leaving room for unconscious or permanent tensions to the detriment of joints, muscles, tendons, organs and systems.
Our instincts react to situations stress preparing for flight or combat by carrying out the related physiological adjustments: increased metabolism (heart rate, blood pressure, sweating, breathing), increased concentration of sugar and fat in the blood, contraction of skeletal muscles, confluence of blood from peripheral areas and secondary organs towards the heart, lungs, skeletal muscles, reduction of gastrointestinal secretions and motility, raising of the pain threshold (betaendorfins), decrease in the activity of the immune system.
While short-term stress can be decisive in dangerous situations (positive stress or eustress), if the stress lasts too long (chronic, negative or distress stress) it can lead to even serious psycho-physical discomfort (including "alteration of the genetic code).
