The Mysterious Effects of Sleeping in the Astronaut Position on Your Body

The Benefits of Sleeping in Zero Gravity Position

Sleeping like you’re in outer space is the “untold secret” to a good night’s sleep here on Earth, doctors say.

The Weightless Position

The sleep experts at Opera Beds claim that the sleeping position known as the “weightless position” (zero gravity) used by astronauts, which involves sleeping with the head up and legs above heart level, with the middle of the pelvis lowered, can improve the overall quality of sleep and well-being, as well as reduce the likelihood of problems such as snoring, arthritis, muscle pain and heartburn throughout the body during sleep.

This pose aims to create a feeling of weightlessness by lifting the upper and lower body at the same time. They were originally developed by NASA scientists to help astronauts balance their weight and de-stress their bodies in microgravity.

Better Sleep Quality

The experts said: “Sleeping in zero gravity reduces pressure on your body and can help you fall into deep, rejuvenating sleep. This position is intended for sleeping on your back and allows the bed to adjust to align your spine to a neutral position.” This sleeping position essentially allows your spine to assume a natural S-shape rather than sleeping positions that are terrible for your back, like sleeping on your stomach with your head on your side.

Pain Relief

Tension, pressure, and poor posture are all common causes of muscle pain, and these conditions can occur for many reasons, such as the way we sit in a work chair. But the weightless position can help to cope with this resulting pain.

Sleep experts at Opera Beds said: “This position mimics weightlessness and relieves pressure, so it can help relieve everyday pain. Often, sleeping in other positions, including on your side, can lead to hip and shoulder pain. Gravity, people with chronic pain can relieve symptoms when the spine is in a neutral position.”


Arthritis causes pain around the joints and also makes them stiff. So it’s not surprising that this affects your sleep, which you need to restore.

Opera Beds experts explained, “Because weightlessness can help release tension in the body, this sleeping position can directly help arthritis. Your weight is evenly distributed in this sleeping position on an adjustable bed, unlike a regular bed, it helps with pressure, which can lead to unpleasant symptoms of arthritis. If you sleep in an elevated position, you also help reduce swelling around the joints.”

Sleep Apnea and Snoring

Experts said: “The weightless position gently raises the head to place you in an optimal position that opens up your airways, helping to prevent vibrations in the throat tissue, which reduces snoring.”

And the experts continued: “The head is also raised to prevent the tongue from falling back into the throat and blocking the airways, which can lead to snoring again, providing a more practical and comfortable solution than piling up a pillow, which can be harmful to the neck muscles.” The head and knees are aligned and raised slightly above the level of your heart. This, combined with minimal stress on the body, allows for improved circulation, resulting in healthier sleep.

Heartburn and Acid Reflux

Since your head is elevated above your heart in weightlessness, this can help prevent heartburn and acid reflux, as stomach acid cannot easily enter the esophagus.

Experts said: “It can also promote healthy digestion. Sleeping in an elevated position helps the body digest food more easily, as sleeping in a horizontal position can slow down the process of digestion and make it more difficult.”

Varicose Veins

Experts say that those suffering from varicose veins can benefit from the weightless position. Varicose veins are swollen veins, mostly in the legs and feet, that cause spasms, swelling, and burning.

They added: “Sleeping with legs elevated helps in the treatment of varicose veins, as it allows them to rest properly without pressure building up, which promotes healing and relaxation.”

Overall, sleeping in the weightless position has many benefits that can improve your sleep quality and overall well-being. To experience the benefits of weightlessness and improve your sleep quality, consider investing in an adjustable bed that allows you to mimic this position and enjoy better rest at night.
