Zero Gravity Chairs place the body in its optimum resting position by making sure that the heart and the rest of the body are on an equal plane. When that happens, our heart has to work less to pump blood to other parts of the body. This, in turn, relieves stress from lower back issues.
Also, when the entire body is on the same plane, blood circulation improves throughout the body. Consequently, with different body parts receiving more than normal supply of blood, they tend to relax and the body health improves.
Those body parts which were aching before you turned to the zero gravity chair stand to gain the most from it. For, with an improved blood circulation, these ailing parts tend to get a fresh supply of oxygenated blood, which helps in their speedy recovery.
Finally, when you’re sitting on a zero gravity chair, your lungs work at full capacity to make sure the blood gets a full supply of oxygen. Consequently, with the blood full of oxygen, it performs a healing effect wherever it circulates in our body.
One of the reasons why astronauts return to earth after a specific time period is because long-term exposure to zero gravity causes bone and muscle loss. Therefore, if you use your zero gravity chair for extended periods every day, you might suffer the same consequences.
