A zero gravity chair with the Zero Gravity position, what is it?
The Zero Gravity position is the ideal position for a perfect relaxation, this sensation is an innovation in the era of relaxation. This state-of-the-art technology provides a deep relaxation by proportionately distributing body weight.
The “neutral” position (NBP) gives you a feeling of absolute comfort like the take-off and rest of astronauts.
Benefits of the Zero Gravity Position
The first Zero-Gravity zero gravity chairs were designed in 1986. The “zero-gravity” posture is recommended by doctors, occupational therapists, and health specialists. This is the posture adopted by NASA astronauts when firing on take-off. This posture allows the alignment of the heart, legs and back for total and instant relaxation and a remarkable reduction in stress. The position of the legs at the same level or higher than the heart can greatly reduce the pressure on the lower back and the entire spine (1).
In addition, the muscular tension in the lumbar region (2) is reduced, the blood circulation in the lower limbs is facilitated and the demand for the heart is reduced. The very open angle between the torso and thighs encourages the expansion of the lungs for better oxygenation.
The zero gravity armchairs with the Zero-Gravity position are without a doubt the most comfortable armchairs, of course, the model chosen is a format compatible with the morphology of the user.
1) Reduced pressure on discs
Vertebral discs have viscoelastic properties. They compress and lose volume when pressurized (disc loading) and resume their initial volume when the pressure dissipates. The higher the pressure, the greater the compression. The effect of the weight imposed daily on the spine during physical tasks and activities causes a subsidence of up to 20mm per day. (Astronauts measure up to two inches more when they return from spacewalks.)
During disc compression and decompression, the migration of the disc liquid (osmosis) allows the nutrients to feed the discs. The osmosis of the disc liquid is essential to the health of the spine. We do not know how often the column should be relaxed for one day to maintain good spinal health. However, we know that osmosis is facilitated during movements (exercises).
Considering the fact that industrialization in societies such as ours leads to the premature degeneration of the column and that more primitive societies develop this problem later, it makes sense to think that relaxing / decompressing discs or exercising More often can only be beneficial.
2) Relaxation of the dorsal muscles
The heart circulates the new blood to the vital organs and parts of the body. The muscles “pump” the blood to evacuate the waste produced by the metabolism towards the heart. Pumping causes a massage action on the blood vessels that pass through the muscles. This action is caused by the intermittent contraction/relaxation of the muscles. When the muscles are in continuous contraction, the blood circulation in the muscles is reduced or blocked. It is important to create conditions to relax the muscles intermittently (see any basic physiology manual as a reference).
Zero-Gravity zero gravity chairs reduce disc pressure and cause muscle relaxation in several ways:
A) The lumbar spine reaches a neutral posture (angle 125-135 between the torso and thighs) The ideal angle may vary according to the individual.
B) In sitting posture, the pressure on the lumbar discs decreases more than when the angle is more open.
• Inclined posture
A) Pressure on the lumbar discs decreases as the torso tilts backward. When the lower back rests on the lumbar support, part of the weight of the torso is transferred to the latter, thereby reducing the weight supported by the lumbar region.
B) The lower back muscles relax in the inclined position.
