The spine is composed of 33 vertebrae, intervertebral discs, muscles and ligaments. The intervertebral discs act as support points for movement and as shock absorbers for the vertebrae. When you jump, when you are standing still... or simply when you sit down, your intervertebral discs compress to protect your vertebrae, absorbing shock or excess pressure.
How does it work? The intervertebral disc consists of an outer fibrous ring and a gelatinous nucleus. This nucleus, made of more than 90% water, generates internal water pressure. This water pressure varies depending on the position of the vertebrae, and therefore on the position that one adopts and the movements performed. As the day progresses, depending on your position, this hydric pressure empties the core of its water, which reduces its damping power.
Fortunately, the nucleus is recharged with water thanks to the presence of hydrophilic (water-attracting) cells that rehydrate it when the pressure decreases while lying down at night.

Prolonged non-dynamic sitting has negative effects on posture. It can lead to skeletal and muscular disorders, but it also increases the risk of many health problems such as :

⦁ Cardiovascular diseases, high blood pressure, ...
⦁ A slowdown in blood circulation, depriving the body of its correct supply of oxygen and therefore the proper functioning of cells.
⦁ An increase in body weight, with an increased risk of type 2 diabetes
⦁ An increased risk of colon, prostate and breast cancer
⦁ Negative consequences on the brain, which receives less oxygen
⦁ Liver and kidney problems
⦁ ........

Studies show that if, in a standing position, the pressure between the 3rd and 4th lumbar vertebrae corresponds to an index 100, the pressure can rise to an index 200 in a poor sitting position. And each day spent in a seated position reproduces the same stress, which in the long run can have a negative impact on your health.

Why adopt dynamic sitting with NOA for your back?

The dynamic seating provided by the NOA cushion stimulates the erector muscles of the spine, which reduces the pressure on the intervertebral discs. This allows the intervertebral discs to function as shock absorbers for a longer period of time. It also helps to better vascularize this area of the body. It therefore promotes the transport of oxygen in the blood, which is essential for the proper functioning of the back muscles. This better vascularisation also makes it possible to nourish the intervertebral discs. In addition, sitting dynamically with the NOA cushion will help you become aware of the position of your back. It will allow you to return to a healthy sitting position that respects the three morphological curves of the back and neck.

Why adopt dynamic sitting with Noa for your health?

Beyond that, the dynamic sitting provided by the NOA cushion keeps the body from going into lethargy. Maintaining correct posture while sitting requires a certain amount of effort that we are unable to maintain over time. We must constantly reposition ourselves to avoid a position that becomes harmful to our health. In the sitting position, the spine no longer has its three natural curves, the pelvis spontaneously tilts backwards, the discs are pinched forward, the core slips backwards, the viscera and vessels are compressed. Even if they seem minimal, the cushion allows exercises of maintenance and compensation thanks to the movements it generates. These imperceptible movements force your muscles to work for all the hours you spend sitting. In doing so, the cushion will, among other things, strengthen your back muscles, an effective means of preventing back pain and improving organ function. Your overall health will improve.
