Ultimate Position In
Relaxation:
Maintaining good posture, even when watching TV or reading a
book is not only good for your spine, it's now made easier with
our new Exclusive Zero Gravity Equipped Adjustable Bed from
Astrabeds.com
Origin:
NASA developed the idea of using a zero gravity position from
the experiences of astronauts who spent many hours while in
orbit. During take-off, astronauts recline with their feet
raised higher than their hearts. This zero gravity position
reduces the amount of gravitational force exerted by the extreme
acceleration it takes to achieve orbit. When you are in an
upright standing or sitting position, gravity places pressure on
your spine causing discs to compress and the back muscles to
tighten to maintain balance. When you are suffering from back
pain, this can be extremely uncomfortable. By neutralizing the
effects of gravity, your back muscles can rest and your discs
can return to their usual normal size and shape. Because of the
effects of gravity, this explains why you are taller in the
morning than you are at the end of your day. Overnight while
sleeping, your back's spinal discs are relieved of the pressures
of gravity and the weight of your body.
Benefits:
When you recline in a true Zero Gravity Position, with
your legs elevated above your heart and an open angle created
between your torso and thighs, a number of good things begin to
happen.
The Position- Also sometimes called "90/90" because of the
approximate right angles that occur at the hips and knees -
immediately puts your back in the correct resting or "neutral"
position.
Since all our body parts are
co-dependent, this Zero Gravity modification begins to have
beneficial effects in other areas:
Correct Spinal Alignment
-The proper neutral position for the 5-curve of your spine is
maintained along the three regions of your back: cervical
(neck), thoracic (upper back), and lumbar (lower back).
Back Pressure Relief -The lumbar
region (lower back), especially, is relieved of almost all
pressure. Disc compression is greatly reduced or eliminated
completely.
Expanded Lung Capacity
-Via the open angle created between the torso and thighs.
Breathing is improved, thereby increasing oxygen levels in the
blood.
Improved Circulation
-With the legs elevated above the heart, stress on the heart is
minimized, and the oxygen-rich blood being pumped to fatigued
muscles helps them to recover faster.
Overall Stress Relief
-The Zero Gravity position approximates the weightless
conditions of outer space, in which the body experiences an
absolute minimum of internal and external stresses.
Unloading of spinal discs
- Human spinal discs have visco-elastic properties. That is,
they compress at a decelerating rate when loaded and expand at a
decelerating rate when unloaded. Higher loads result in a higher
rate of compression. Spinal loading from daily activities will
cause shrinkage in stature, of up to 20mm over the day. This
transfer of fluid in and out of the disc is the body's mechanism
for supplying nutrition to the discs. Spinal discs do not have a
direct blood supply, and this osmosis and diffusion is essential
to maintaining spinal health. It is unknown how often the spine
needs to be "unloaded" during a day to maintain good disc
health. Of course, disc fluid transfer is also increased with
movement (that is, exercise!). Given that the onset of
degenerative spinal changes occurs is commonly at a young age in
industrialized societies such as our own, and that these
degenerative spinal changes occur only at more advanced ages in
primitive societies, it is likely that we need much more
unloading and/or exercise in our daily lives than we currently
get. Loads on the lumbar spine are reduced in neutral lumbar
postures. Technically speaking, the neutral posture is defined
as being near the mid-point of the available range-of-motion in
that body region.
Relaxation of spinal muscles -
The heart pumps blood, full of nutrients and
oxygen, to our body parts. Muscles "pump" blood, carrying the
waste products of metabolism, back to the heart. The muscle pump
works by massaging the blood vessels which pass through them.
The pumping massage action occurs as the muscles intermittently
contract and relax. During sustained muscle contractions, blood
flow through the muscles is restricted or occluded. So it is
important that the muscles have intermittent opportunities to
relax.

closest thing you'll find here on earth to the weightless
conditions of outer space.
