Did you know that the load pressure on the intervertebral discs is greater when sitting than when standing? And this difference is not small - it is a whole 75 kg!
You are probably wondering how this is possible, as we are sitting and resting. To understand the functioning of the spine and its burden, you first have to see what the backbone is comprised of:
Each of the components has its role, and together they allow us to move. A generalized description of the spine: intervertebral discs in a healthy spine absorb shocks and vibrations, while the vertebrae provide the back with sufficient support.
The joints in the spine facilitate the accurate fit of the components and, at the same time, together with ligaments, make sure that there is no "dislocation" of the spine.
The nerves (or nervous system) point to burdening or other damage while muscles allow movement of the whole.
Each part of the spine is further composed of even smaller elements, which make the backbone flexible but at the same time firm. In case of damage to only one of these elements, this is indicated by pain.
Damage is mainly due to overburdening and / or lack of exercise. In both cases, the spinal column starts to lose its flexibility and mobility becomes limited.
The SpinaliS Chair solves this because it allows active sitting which strengthens the muscles, keeps ligaments flexible and prevents point burdening of individual parts of the spine, due to the continuous movement.
The spine supports and carries the upper part of the body. For this reason, it is always burdened. The spinal load is measured by the pressure inside the discs, created by body weight, body posture and external weight (lifting).
The burden on the spine is lightest in a laying-down position and is around 25 kg. Interestingly, the pressure on the inner part of the intervertebral discs is higher when sitting than when standing. In a standing position, the pressure is increased to 100 kg, while sitting it is at 175 kg.
In an upright position (standing) part of the burden of the intervertebral discs is borne by ligaments and muscles. When sitting, the muscles and ligaments relax, which increases the workload and pressure on the intervertebral discs. Additional pressure induces irregular posture. Due to the ever-increasing presence of sedentary work and longer periods of sitting, muscles and ligaments become more lax. This increases the burden on other parts of the spine, which assumes the burden of the inactive parts, leading to injury. Long-term burdening (increased pressure) on the intervertebral discs in the short term is welcome because, like exercise for the muscles, it helps strengthen the intervertebral discs and keep them healthy.
Excessive and / or permanent over-burdening of the intervertebral discs causes spillage of liquid contained therein. With the gradual desiccation of the intervertebral discs it also minimizes the distance between them, which leads to friction, often by trapping a nerve or even the complete destruction of the intervertebral discs.
More exercise, relaxation and a healthier lifestyle will help you maintain a healthy spine. But how, when you are bound to sitting many hours a day, at work and at home? This is where the SpinaliS chair helps. SpinaliS is the only chair in the world that allows for comfortable sitting while also mimicking the active sitting that takes place on a therapeutic ball, which is what therapists recommend as the best tool for healthy sitting. SpinaliS can help you even more - with a very precise ergonomic design, making your work environment healthier and more easily accessible. And it's not at the expense of your spine.

SpinaliS is important for preventive measures
The idea of constructing a chair with a moving base or moving seat seems to me to be one of the very important things in preventing the degeneration of the discs. Because of the constant movement of the seat back muscles have to work constantly, so there is no unilateral burdening of the spine and l discs, but the burden is distributed to the entire spinal area, sometimes more on one side, sometimes more on the other.

Stol SpinaliS toplo priporočam vsaki bodoči mamici
Sem mamica dveh otrok in med drugo nosečnostjo sem ves čas vodila ginekološko ambulanto, doma pa so me čakale še običajne vsakodnevne obveznosti. Morda sem se ravno zaradi stola Spinalis, redne vsakodnevne vadbe, ki pa časovno ni presegla 15 minut, v nosečnosti počutila izredno dobro.
Stol SpinaliS toplo priporočam vsaki bodoči mamici, saj vsaka lepa ura v nosečnosti pomeni veliko več kot ostale ure v življenju.
