The spine consists 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, stand awkwardly... or simply sit, your intervertebral discs compress to protect your vertebrae, absorbing the shock or overpressure.
How does it work? The intervertebral disc is composed of an outer fibrous ring and a gelatinous nucleus. This nucleus, made of more than 90% water, generates an internal water pressure. This water pressure varies according to the position of the vertebrae, i.e. the position we adopt and the movements we make. As the day progresses, depending on your position, this water pressure drains the core of its water, which reduces its shock-absorbing power.
Fortunately, the nucleus recharges itself with water thanks to the presence of hydrophilic (water-attracting) cells that rehydrate it when the pressure drops 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 slowing down of blood circulation depriving the body of its proper oxygen supply and thus the proper functioning of cells.
⦁ An increase in body weight, with an increased risk of type 2 diabetes
⦁ An increased risk of colon, prostate, breast cancer...
⦁ Negative consequences on the brain which receives less oxygen
⦁ Liver and kidney problems
⦁ ........

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

Why should you adopt dynamic seating with NOA for your back?

The dynamic sitting position of the NOA cushion stimulates the erector muscles of the spine, which reduces the pressure on the intervertebral discs. This allows them to play their role as shock absorbers for longer. It also improves the vascularity of the entire 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 helps to nourish the intervertebral discs. In addition, sitting dynamically with the NOA cushion will help you to become aware of your back position. It will help you to find a healthy sitting position that respects the three morphological curves of the back and neck.

Why is dynamic sitting with Noa good for your health?

Beyond that, the dynamic sitting provided by the NOA cushion prevents the body from becoming lethargic. Maintaining a correct posture while sitting requires a certain amount of effort that we are unable to maintain over time. We have to keep repositioning ourselves to avoid a position that becomes unhealthy. When sitting, the spine no longer has its three natural curves, the pelvis tilts spontaneously backwards, the discs are pinched forward, the nucleus slides backwards, the viscera and vessels are compressed. Even if they seem minimal, the cushion allows for support and compensation exercises thanks to the movements it generates. These imperceptible movements force your muscles to work during all the hours you spend sitting. In doing so, the cushion will, among other things, strengthen your back muscles, which is an effective way to prevent back pain and improve organ function. This will improve your overall health.
