Can Zero Gravity Massage Chairs Help Your Spinal Column?
One of the new trends in massage chairs is the zero gravity massage chair. We are starting to see the zero gravity position becoming mainstream with certain recliners. Does this mean that you are weightless in the chair? If so, then I think the age of the Jetsons has arrived. Unfortunately, the technology is not quite there for us to float in the chair. What is zero gravity and what is its relationship to massage chairs?
So let’s start with the basics. Zero gravity is a place where there is an absence of gravity. To understand gravity, it is a force coming from the mass of a particular object. Every object in the universe has some level of gravitational pull. However, the gravity can only extend within a certain range from the object. When you are beyond the range of any objects gravity, then you are in zero gravity.
We can only associate zero gravity with pictures we see of astronauts floating. We see them spray in the air and it just continues in the same direction. There doesn’t seem to be any direction up or down.
How did a zero gravity chair come about? Well, one of the challenges of space travel is to escape the gravitational pull of the Earth. In order for a rocket to get to outer space, it must overcome the force of gravity from the earth itself. This requires a tremendous amount of thrust to escape from this tremendous force.
The astronauts when they launch their rocket must bear a tremendous amount of force. Minimizing the wear and tear on the astronauts was an important consideration. It was soon found that if an astronaut was in a fully recline position, then there was less stress put upon them during takeoff.
The development of the zero gravity chair was an enormous success for the astronauts. This help them better withstand the forces of takeoff. Imagine you have to start your mission by pulling multiple g’s. This is tremendous wear and tear on the body. Remember, this is the first 15 seconds of the mission. The zero gravity position was important because it better distributed the weight of the astronaut.
This became the standard takeoff position for astronauts. It is now known as the zero gravity position. This helps the astronauts to endure the rapid increase in gravitational force. This enabled the weight of the astronaut to be more evenly distributed across their body to absorb these extra forces of takeoff.
Back on Earth, you can choose from a selection of zero gravity massage chairs. Although, they will not help you escape the forces of Earth’s gravitational pull. However, they generally have two main functions. The first is to better distribute your weight for relaxation. Some of these recliners may elevate the legs above the heart.
One class of zero gravity massage chairs seeks to spread your weight more evenly across your body. When you are in the reclined position then your weight is distributed across the surface area which is in contact with the entire recliner. This helps to spread the forces on the body.
Some zero gravity recliners can elevate the legs slightly above the heart. This has the additional benefit of reducing swelling and improving blood flow to the region. It is common medical practice to elevate their part of the body to reduce swelling. This can also be accomplished by lying flat and elevating the body part as well.
I hope we have unraveled the mystery to the zero gravity massage chair. This is a new feature which is being integrated as a way to further induce relaxation. You will not be weightless in the chair; however you will feel much more relaxed. There are quite a few good zero gravity massage chair models on the market. Try one and see what you think.
