Benefits of the Zero Gravity Position

While zero gravity may sound like a term that’s straight out of a sci-fi film, its use in recliner chairs can have significant benefits for your health. From enhancing your circulation and reducing ulcers to improving your lung function, there are lots of reasons to consider a Perfect Sleep Chair.

What is Zero Gravity?

In the 1960s, NASA began sending astronauts into space to examine the universe surrounding us. While their missions initially involved fleeting experiences, NASA started extending the amount of time astronauts spent outside of the Earth’s atmosphere. It wasn’t long before each one began reporting adverse health effects, including unwanted weight loss, muscle wastage, and a reduction in bone density.

From there, NASA went back to the drawing board to see how it could send its professionals into space without impacting their health. Eventually, they developed the zero-gravity concept, which involved using pressure to hold the astronauts in place. Thanks to the techniques they created, the poor health effects NASA’s astronauts encountered were reduced. Today, similar techniques exist in recliner chairs and sleep chairs.


The Mechanics of Zero Gravity

Unlike an astronaut, the mechanics of your zero-gravity chair won’t cause you to fly into space. Instead, it adopts the same reclining position that allows astronauts to accelerate through space without letting gravity impact their bodies negatively. Such chairs will achieve the benefits of zero gravity in several ways:

  • They distribute your body weight throughout the chair, which means gravity places less stress on some areas of your body.

  • More specifically, the chair will elevate your legs and allow you to adopt something called the Trendelenburg position. The Trendelenburg position works with the small valves in your veins that allow blood to return to the heart in a smoother manner.

  • At the same time, elevating the legs alongside a sleep chair’s massage function means that two factors work alongside each other. By causing your muscles to move, lift chairs that deliver massages cause the muscles that help your veins’ valves to open more easily than if you simply recline.

Zero Gravity’s key benefits

As you age, a loss of muscle mass and a reduction in bone density become more likely. Every person rebuilds their bones by reabsorbing phosphate and calcium from them. For a significant proportion of the population, such processes become less effective as they age. With zero gravity, you have the opportunity to place less stress on your muscles and bones. As a result, both can support each other a little better. It’s also worth noting that there are other health benefits too.

How is Zero Gravity beneficial to your health?

Although moving around is a key factor in building bone density, constantly fighting against gravity can have negative effects too. Around 10 million people in the U.S. suffer from osteoporosis. When you use zero gravity, your body isn’t fighting against the Earth’s pull against your bones. Although the exact science behind why lift chairs featuring zero gravity isn’t fully understood, some scientists believe it’s due to the regulation of an enzyme that can exacerbate conditions such as osteoporosis.

Your muscles experience benefits too

Sleep chairs such as the Perfect Sleep Chairs combine massage with the freedom of reclining to an endless number of positions, including zero-gravity. By distributing your weight evenly, zero-gravity allows your muscles to enter a state of relaxation. As a result, Perfect Sleep Chairs limit tension. As the tension in your muscles is reduced, the chair will massage them to relax them further, giving your muscles a chance to heal after a long day.

You’ll encounter better circulation

When lift chairs allow you to elevate your legs and aid your veins’ valves in opening more, blood returns to the heart faster. There are several benefits to elevating your legs when it comes to your circulation:

  • Your heart’s right atrium receives old blood containing toxins and carbon dioxide faster. Because of this, its partner, the right ventricle, doesn’t have to pump as hard to return blood to the lungs for reoxygenation.

  • If you suffer from conditions that predispose you to ulcers or edema in your legs, you’re less likely to develop blood pooling. Blood pooling can cause pressure against your skin, resulting in painful ulcers that become difficult to heal.

  • When your blood’s cells have the chance to receive oxygen at a greater pace, that oxygen reaches other organs, giving them a chance to reperfuse (The restoration of blood flow to an organ or to tissue). When reperfusion occurs after the use of sleep chairs, your body’s organs are more likely to work with each other to place less strain on each body system.

Your lungs will see the benefits of zero gravity too

Your lungs depend on several surrounding structures to function. One of the most important ones is the diaphragm, which is a large muscle that works hard to help your chest expand. Your lungs then fill with air. When you use lift chairs that recline, your diaphragm allows for maximum expansion, which then improves your lung function. Over time, expanding your lungs more can lead to deeper breathing, which then sends more oxygen throughout your body

Why choose the Perfect Sleep Chair?

The Perfect Sleep Chair’s designers have designed the chair to give you the freedom of reclining to infinite positions. An Infinite position chair features two motors in the sleep chair; one at the legs and one at the back. This allows you to fully recline, and you achieve greater flexibility when moving the chair, as the two motors don’t have to operate at the same time.

Perfect Sleep Chairs act as all-in-one solutions

Each of the Perfect Sleep Chairs available act as all-in-one solutions. The lift chairs can adopt an endless number of positions, making your life simpler:

  • Lift: Which helps you transfer from a sitting to a standing position, or vice versa.

  • Sitting: A more upright position that makes visiting with loved ones comfortable.

  • TV Watching: A mild recline that makes watching TV more relaxing.

  • Zero gravity: A position that comes with a multitude of health benefits.

  • Sleeping: A complete recline that’s similar to your usual sleeping position.

Massage and heat functions that soothe aches and stresses

Everyone develops aches and pains throughout the day, but there’s no denying they become more common as you age. Perfect Sleep Chairs are lift chairs that feature massage and heat functions you can customize to your own comfort level. Each function is available at the touch of a button, giving you luxury relaxation in a recliner chair.
